W. T. B. ROBERTS ET AL MACHINE FOR APPLYING TAPE T0 SHEET MATERIAL Filed May 25, 1929 2 Sheets-Sheet 2 Patented Oct. 11, 1932 Umran STATES WILLIAM THOMAS BUCKINGHAM ROBERTS AND HARRY HARDY JACKSON, OF LEICES- TER, ENGLAND, ASSIGNORS TO UNITED SHOE MACHINERY CORPORATION, OF PATER- SON, NEW JERSEY, A CORPORATION OF NEW JERSEY MACHINE FOR APPLYING TAPE TO SHEET MATERIAL Application filed May 25, 1929, Serial No. 366,057, and in Great Britain June 9, 1928.
This invention is concerned with improvements in machines for applying tape to sheet material and is herein illustrated and described as embodied in a machine for apply- 3 ing adhesive tape to boot or shoe uppers.
- Such uppers generally comprise two parts united together by a seam (usually called the back seam) which seam extends, in the finished boot or shoe, up the back thereof from the heel seat to the top of the.up-
per.
The, margins of the two parts where they are joined by the seam necessarily stand up from the body of the upper along the length v of the seam due to the presence of the seam and form a ridge, and it is desirable that this ridge shall be flattened down somewhat in order that it shall not chafe the foot of the wearer. reason and also to strengthen the seam, to cover the ridge by a tape secured to the parts of the upper on the respective sides of the seam close to the latter, the tape overlying the seam rid e along the length thereof. In the United tates Letters Patent No. 1,646,- 212', granted Oct. 18, 1927, upon an application filed in the name of Walter 1?. Osgood, and in the British Patent No. 297 ,349, there are described machines which may be used to operate upon a boot or shoe upper along the back seam to press the seam ridge to fiatten it while applying adhesive tape along and over the seam, the flattening of the seam ridge and the application of the tape being eflected in a single operation and by the same instrumentalities, which include a Presser having an oscillatory movement.
According to the present invention novel and improved means are provided in a tapn 1 ing machine for eflecting oth the flattening of the seam and the said taping.
\ In one of its several aspects the present invention provides a machine having means for flattening the seam ridge and other means a: for applying the tape therealong only after It is also desirable, for the same it has been so flattened. The tape applying means may comprise a roll.
In another of its several aspects the present invention provides in one and the same ing-and tape applying means operate continuously uponthe work during the whole of such time as the latter is presented to them. This enables the seam pressing and tape applying operations to be eflected in the minimum of time and therefore allows separate pieces of work to be fed to the .operating means in quick succession.
In still another of its aspects the invention provides a machine comprising a pluralit of rotary tools, one of which uides the Wor in a direction lengthwise o the seam, another of which rubs down the seam ridge, and another of which applies the adhesive tape to the seam.
The invention will be readily understood from the following description, reference being made to the accompanying drawings, in which, I
Fig. 1 is a front elevation of the said ma 1 chine Fig. 2 is a side view partly in section and on an enlarged scale showing the relative positions of certain parts of this machine;
Fig. 3 is a plan view of the parts shown in Fig. 2;
Fig. 4 is a detail view on a still larger scale showing the formation of one of the parts shown in Figs. 2 and 3; and I Fig. 5 is a plan view of a work sup ort.
The machine now to be-described 1s, save as otherwise indicated, similar to themachine described and illustrated in United States Letters Patent Nos. 1,259,134 and 1,474,350, granted March 12, 1918 and Nov. 20, 1923 upon applications filed respectively in the names of WilliamT. B. Roberts and Frederick William Farrar, and reference will frequently be made to the former of these specifications throughout the following description. The machine illustrated in the accompanying drawings comprises a frame member consisting of a base 1 and an overhanging arm-3 rising from the ri lit-hand side of the base (viewing the m8.0l11ll8 from .the'front) and extending to the leftover the base at a considerable height thereabove as shown in Fig. 1.
. A short main shaft 5 (ex tending from theright towards the left of the machine) is mounted in horizontal bearings in the base 1, and the'right-hand'end of this shaft projects beyond the right-hand end of the-frame. Fast and loose pulleys 7 and ,9 are arranged uponthis end of the main shaft, and a-belt shifter(not shown) is provided to shift a driving belt from the fast to the loose pulley A second horizon-ta shaft-10 extending from the right towards the left of themachine is mounted in bearings in'the overhanging arm and has secured to it at -itsfright hand end whichprojects beyond the frame) a pulley- 11 adapted to be driven by a belt from. another pulley 13 fast on the main shaft'5 aforesaid. The left-hand end of this second hori- I hanigmg arm substantially over and parallel wit "the second horizontal shaft .10. The right-hand end of the shaft 17 has a pulley 19 secured to it and a pulley 21 fast on the main shaft 5 is coupledb' belting to this latter pulley'19 through re ucing ulleys 23, 25 mounted ona countershaft 27 v etachably secured to the back of the arm 3. B
at a lower speed than is the one 10 immediately belowit carrying the rubbing roll 15. The horizontal shaft 17 extends completely across the machine to the left-hand side thereof and carries on its left-hand end, outside the machine frame and as shown in Fi 5 of the drawings of the Letters Patent dast mentioned, a small pinion. This pinion meshes with anidler pinion mounted below it in a stub-shaft secured to the frame. Two smaller pinions are arranged below the idler pinion as shown in the machine of the same Letters Patent and are driven thereby, the said pinions beingvspaced apart around the lower periphery of the idler pinion, and bein adapted, as in the patented machine, to drive the shafts of two of the work engaging rolls.-
One of said pinions (ie., the one nearer (or vlce'versa) as desired."
I the this means the upper horizontal shaft 17 is rive n from t to the front of the machine) is secured to a short shaft 291(see Fig. 3) extending towards the right as viewed in Fig. 1 parallel to the shaft .10 carrying the rubbing roll, the righthand end of .the short shaft 29 lying close to and alongside the rubbing roll-15 on the forward side thereof. A combined seam opening, work-feedingand guiding device more fully described in said Letters Patent No. 1,474,350 is mounted upon the right-hand end of this short shaft 29, said device comprising two smooth conical portions 31, 33 arranged on the shaft with their smaller ends facing each other and with a peripheral rib 35 (formed on the shaft) between the coni cal portions. The conical portions are'slidable on the shaft (but cannot rotate relatively thereto) and are each urged inwardly towards the other and towards the said rib by springs 37,- 39 arranged behind them. Each of said conical portions is approximately some twenty-one thirty-seconds of an inch in diameter at its widest part and some sevensixteenthsof an inch at its narrowest part.
The rearmost of the .two small pinions aforesaid is secured to a shaft similar to that just mentioned but positioned on the other side of the rubbing tool 15 (i. e., the rear side). Fixed upon the right-hand end of this shaft alongside the rubbing tool is a tape-applying roll 41. This tape applyingroll is employed in place of the ironing rollreferred to in said Letters Patent No. 1,47 4,- 350 and differs therefrom in form, consisting of a smooth roll some five-sixteenthsof an inch in diameter having two diametrically opposite'portions of its periphery flattened as shown at 43 (Fig. 2) to allow the work tobe presented easil manipulated relative y thereto while it is being acted upon by the roll.
' A eripheral groove45 (Fi .4) (to receive attened seam ridge as" ereinafter explained) is, however, cut in the cylindrical portions of the roll surface at such a position along the length thereof that its middle is directltyl in line (when looking at the machine e front) withthe aforesaid peripheral rib 35 forming part of the workvice. I The peripheral groove 45 1s approximately an eighth of an inch wide and one thirty-second of'an inch deep.
A carrier 47 (Fig. 1) for a roll of adhesive tape is mounted on the rear of the machine on the overhanging arm 3 and tape from a roll on the carrier is led from the under side of the roll down a guide 49 positioned over the tape applying roll 41. The tape guide 49 is so positioned with respect to the tape-applying roll 41 that the tape can extend from the ide round the forward side of the roll, over yingthe groove'45, and under the underside of t e roll as indicated in Fig. 2. The tape guide'49 comprises a pair of side members 51 securedto a bed 53 which is adjustto the rolland to,be
guiding debeing operated upon, a carrier for a work-- bear upon the tape applying tool 41 to clean it. 'A set screw 63 passing through a. downwardly turned end of the guide bears against the pivoted block 55 to limit the position ofthe guide relatively to the tape applying device. A spring detent 66 in the guide is ar-' ranged to press on the tape and to allow the tape to be drawn forward during the operation of the machine; but it prevents the tape running back at the conclusion of the operation, as it isliable to do on account of the tendency of the roll of tape to draw the tape in again when the tape is severed at the end of an operation. The tape guide is rigidly but adj ustably secured at the desired height over the tape applying tool on a stud 56 supported in ears projecting from the rear side of the overhanging arm 3.
From the foregoing description it will be evidentj that as shown in Fig. 2 work fed through the machine from the front will first of all be acted upon by the work-guiding and feeding device 31, 33 and will be fed by the latter to the grooved or corrugated rubbing tool 15 after which it will be fed to the grooved tape applying roll 41 tohave the tape only then laid on and pressed securely to it. a
In order to support the work while it is support is arranged on the base 1 of the frame directly underneath the operating tools substantially as described in Letters Patent No. 1,474,350 aforesaid. 'The work-support comprises a block 65*which normally occupies an inoperative position below the tools but can be raised by a treadle (not shown) into operative position close to the underside of the tools when work is to be presented to the machine as shown in Figure 2. The upper face of the block 65, upon which the work rests while it is being operated upon, is slightly convex when viewed from the side as shown in Figure 2, and the edges of the upper face are beveled off at the leading end of the block as shown at 67 for about half the length of the convex face to form a central V-shaped ridge 69 (in the illustrated machine about an inch and a half lo ig) with which the workguiding and feed roll co-operates and which helps to guide the work as it is being presented to the machine. The rear part of the convex face also has its sides bevelled off as shown at 71 but instead of forming a sharp V ridge as at the forward end they form a V ridge terminating in a narrow, and almost fiat,
work-supporting face 7 3 which is roughly a quarter of an inch wide and about an inch long.. The slo ing faces of the front V- shaped part of t e work support are ada ted to co-operate with the conical parts o the work-guiding and feeding member n presenting the work properly to the tools; and the narrow, flat, work-su porting face 73 last mentioned is adapte work while the seam ridge is being rubbed down by the corrugated rubbin tool 15.
The part of the work-support or cooperatto support the.
in with the ta e-applying roll 41 comprises ters of an inch in diameter) mounted in a yoke 77 which is attached as hereinafter described to the rear face of the block 65 aforesaid. The yoke has projecting forwardly from it a stud 79 perpendicular to the roll axis whichenter's into a substantially horizontal hole in the block; and a slot cut in the face of the stud receives within it a stationary pin 81, there being limited relative freedom of movementbetween the pin. and slot. The arrangement is such that the yoke 77 and therefore the roll 75 carried thereby can tilt about-a substantially horizontal axis (that is the stud axis 79) which lies in the vertical plane containing said sharp V ridge 69, to an extent limited by contact of the said pin 81 and slot. The generally convex face of the a reely rotata le roll 75 (about three quar work support as seen in Fi ure 2 (i. e., from i the side) and the top portion of the periphery of the said roll 75 form a more or less back seam in the work to beoperated upon,
is supported approximately along the whole length of the work-support. Such convexity corresponds roughly to an are about three inches long struck with a five inch radius.
The roll 7 5 (Fig. 5) itself comprises two coaxial cylinders of metal or other rigid material and of equal diameter, screwed together and clamping between them a yielding washer 85, of rubber for example, the periphery' of which lies very slightly below the periphery of the roll. This rubber washer is arranged midway along the length of the roll and lies directly underneath the groove 45 in the tape-applying roll 41. The outer ends of the cylindrical parts of the roll are bevelled as shown in Figure 5 to make the peripheral supporting face of the roll generally similar in lateral formation to that of the adjacent part 71, 73 of the work supporting block but leaving the central part I of the tape. The widthof the rubber washer is about three-sixteenths of an inch, that is to say somewhat greater than the width of the groove 45 in the taping roll'41. The shaft-s before described which carry' the guiding, rubbing and tape-applying-rolls are so located that the active portions of said rolls are disposed, when viewed from the side, on
a curve similar to that presented by the upper faces of the various parts of the worksupporting means as shown in Figure 2.
.The mountings for the guiding, rubbing and tape-applying rolls are so arranged that the rolls may be urged downwardly on to the work by springs; and ad usting means 87 are raised or lowered by itself or the work guiding and taping rolls raised or lowered in unison.
The operation of lows Assuming the machine to be running (i e., all the three. rolls to be rotating) and the work-support to be in its normal lowered position, the operator raises the latter by means of a treadlc (not shown) to its working position. He then takes a piece of work, opens it out and urges its leading edge into the bite between the parts 31, 33 of the combined work-feeding and guiding roll and the worksupport 65, the two pieces of work joined by the machine is as folthe seam straddling the work-support and -the seam itself overlymgthe V-shaped rib 69 thereon. The rib 35 on the work-feeding and guiding roll enters in the gap between the two narrow margins of upper projecting from the seam thereby separating them and serves to guide the work to the rubbing tool, while the pressure on the sides of the seam ridge exerted by the conicali'nembers 31 and 33 and the pressure of the roll on the work serve also to feed the latter by friction. The work is passed thereby to therubbing to l 15 by which the seam ridge is rubbed down. The work thereafter passes to the taping roll 41 and. owing to the flattened parts on the taping roll before mentioned, enters readily therehetween. As the work comes under the taping roll the adhesive tape passing-around the front of this roll and rearwardly under it is, by the action of that roll, automatically laid on and pressed against and secured to the work on both sides of the already rubbeddown seam parts. The steam ridge, together with that part of the tape overlying it, enters into the groove 45 in the taping roll, and the depth of the groove is so chosenas to be somewhat less than the thickness of the work at the flattened seam ridge plus the thickness of the tape. The taped work at i to accommodate the extra material and allow the taping roll to press the tape on the work at each. side of the seam parts while also pressing by the bottom of its groove 45 on the tape on top of said seam parts and continuously and uninterruptedly pressing the same notwithstanding the presence of the flats 43. Should the portion of the work at one side of the seam parts be thicker than that on the other, the supporting roll 75 under the taping roll will tilt on the axis of the stud 79 to accommodate itself to this varying thickness and will tend thereby to distribute the pressure evenly over the work on both sides of the seam ridge.
As will have become apparent all the rolls, with the exception of the seam rubbing roll, are smooth: and, owing to the work which the latter has to do in flattening the seam ridge and the. consequent resistance ofl'ered thereby to the passage of the" work through the machine, slippage occurs between the other driven rolls and the work. The work is therefore fed through the machine by the friction of the driven rolls at a speed considerably less than the slowest peripheral speed of anyof these rolls.
' It is to be understood, however, that all the driven rolls (i. e., {those above the work) rotate in the same direction (i. e., anti-clockwise as seen in Figure 2) and they all play some part therefore in feeding the wor through the machine while both the seam flattening and the tape-applying are, if not essentially at all events largely, rubbing or wiping operations.
The drawing-off of the tape from the supply is controlled by the passage of the work through the machine, the flattened faces 43 on. the tape-applying roll releasing the tape intermittently so as not to feed it too fast; the tension'on the tape as it is drawn from' the supply also prevents excessive feed of the tape.
We have found that where separate fric tional tools are used for applying the tape to the material and for feedmg the work and for rubbing down the seam, it is difficult to provide such an arrangement thateach tool will perform its particular duty efi'ectively. If one or other of the-tools does not operate in proper harmony with the associated tool, then wrinkling of the upper or of the tape or failure of the tape to' stick is liable to occur. By forming the tools as above described with referenceto the drawings and by so organizing the tool driving means that the rubbingdown roll-15 rotates at approximately two thousand eight hundred revolutions per V upon the seam ridge, means being operable to apply tape to. each 5 portion of the seam ridge only after thatv minute while the work guiding and feeding . roll 31, 33 and the taping roll 41 each run at approximately five hundred and forty revolutions per minute, no difliculty has been found under ordinary conditions in feeding the work and the tape non-positively at the ,correct relative speeds while performing means operable subsequently to the operation of said flattening means for applying adhesive tapeupon said portion of the seam ridge.
