Patented Jan. 16.193126 Application filed September 1%. 1910. Serial No. 581,983.

To all whom it may concernlle it known that .l. linear-inn (it nwnor, a suh ieet of the King of Prussia. residing at No. ll d'orinserstrasse. in the city of lien tin. German Empire. have invented certain new and uset'ul improvements in Machines tor lroduoing Fabric. Paper, or tlardbmird Having: an lnelosui'e of Cross ing: 'lhreads; and I do hereby declare the following; to he a toll. dear, and exact deaeription ot' the same.

his" in ention relates to a machine for prodneihQ' 'lahrie'. paper. or r-ard board having an ii'ielosure ot' eros. ng threads, preferably of Crossing metal wires. A process for prodin-in; paper with such an inelosure is known. zit-wording to whit-h a series of longitudinal wires or the like is introdut'ed betwe n two widths of paper or tabrit', whereupon a HQI'lOH of transverse wires is inserted. so that. on stirking the widths of paper together. which is done in the well known roll sinking machine. the wire in closure is fastened. in the prot-esseis and ioat'hinee of this kind heretofore known the threads inserted aeross the loi'igitudinal threads were inserted in. a more or less loose rendition. that is without suttirient tension. 'lhese transverse threads were not able to prevent the paper from being torn. because they were only able to otter resistanee after the paper had been broken. lhis drawbaek orert'oine by my invention. as I insert the transverse threads under tension and keep them stretehed. until they are tightly grasped by the pressure roll of the sticking mat-hiue and eannot get out of position. in my invention the transverse threads are raun'ht at their tree ends and are pulled at a oertain tension from a spool. and then. while still retaining this tension, are introdured. parallel to eaeh other. into the apparatus designed to t-ombine the separate widths. my maehiue being provided with suitable derives. whieh enable the wire to he kept under tensit n. ;,nntil it is taken hold of by the pressure rolls: and cut.

tin the accompanying drawing illustratin r sueh a niarhine by 'ay of example, l igntre t is a side elevation and a part seetion on the line A-B of Fig. 2. Fig. 2, a plan of the front part of the machine. and Fig. a front elevation. while Figs. 'l:-l 1 show details.

The two widths of fabric, paper or the like. are combined with the wire inclosure between the two rolls 1 of the sticking inaohine. To these rolls thepaper width is led from above. while the paper width 3 in introdueed from below. The lower paper width 3 is previously passed over a. roll 4. whit-h rotates in a vessel 5 containing an adhesive. so that this adhesive is applied to one side of the paper width Bet ween the widths of paper 2 and 3 a series of longitudinal wires it are intrmlueed. which are wound otl spools 7. At the same time the wires 8 are introduced between the widths at an angle to the longitudinal wire 6. By the pressure of the rolls '1 the paper widths are continued and the wire inelosnre is thus fixed. 'lhe finished paper with inelosnre then led in suitable manner over a drying drum 9. hiarhines oi this kind are already' known so that a more detailed description will not he neeessanv.

My invention relates to the manner of introducing: the transverse wires. The apparatus. as above mentioned. must fulfil the conditions that said transverse wires are in serted parallel to eaeh other and at a right angle to the longitudinal wires. and that.

before all. the transverse wires are kept under tension. until they are taken hold of by the pressure rolls of the maehine.

Arvin-ding to my invention the series of transverse wires H are gi'iided and moved to ward the pressure rolls 1 by two rotary disks it). it. which are provided in the same. horizontal plane. Said disks to. 11 rotate'abtait their vertical axes at a unilorm speed in opposite dirertions. ()n the disk is provided a number of wire spools 12 at a uniform eireuinterential distance from each other, from each of which spools a wire passes to a nozzle 13 provided at the edge of the disk. (lot-responding to earh nozzle 13 there is a gripping device 14 on the rotary disk 11. Said grip 'iingg devices 14 are so arranged at the edge of the disk 11 that at the point at r" tat which the circumferences of the two disks 10, 11 are nearest together, a nozzle 13 is always exactly opposite a gripper 1-1. At this point the gripper 1 the construction and operation of which I will describe bclow, seizes the end of the wire projecting out of the nozzle 13. According; as the distance of the respective nozzles and grippers, owing to the rotation of the disks 10, 11, increases, the wires will be drawn d the spools 12 and introduced parallel to each other between the pressure rolls 1.

In order to explain the manner of guiding the wire from the spool 12- to the nozzle 13 I refer to Figs. i-6. Fig. l is a radial sec-- tion through the outer part of the horizontal disk 10. Fig. is plan thereof and Fig. ll a section on the line. C-l3 of Fig". The wire drawn oil the spool 12 is first led around tightening pins 15 secured to the disk and then through the slot 16 of a guide piece 1'? and under the roll 18, which rotates about the cylindrical part of a screw 20 inserted in the forked end 21 of a bell crank lever 22. From the roll 18 the wire passes over a cross piece :23 and through a guide 24 on the dish 10 and then tlllOllQll the nozzle 13. In order to prevent the wire from being injured by the front edge of the nozzle 13 a roll 25 is arranged in front thereof. As soon as the respective gripper ll has seized the projecting free end, the wire 8 is subjected to a certain tension and the bell crank lever which can rotate about the pivot. 26 in the guide block is gradually raised until it reaches the position 22 shown in dotted lines in Fig. l. The highest position of the lever 22 is detern'iined by the stop 27, which then bears against the top edge of the lever. As soon as the. pull at the end of the wire 8' projecting out of the nozzle ceases, that. is, as explained below, when the wire is cut. the bell crank lever falls again by rcasoi'i of its own weight. It then pulls the wire 8" back to such an extent thatv only asmall piece projects through the nozzle 13, which is adapted to be caught by one of the grippers 14-, as soon as the disks 10. 11 have described complete revolution. In this wa) all waste ofwire is avoided and the gripper is caused to takehold of the wire at its end. By the wire being pulled back through the nozzle, the free end, which as evident from Fig. 2, is bent sidewise over the roll 25 by the lateral pull, will be straightened.

in order to assure that the wires, when being drawn oil their spools l2 receive a certain tension, a special brake is provided for each spool 12 (Fig. 7). ()n the circiunferonce of each spool bears a brake block 28, which is carried by a spring 29. The inner ends of these springs are all fastened to a. ring 30. which is connected to the disk 10 in suitable manner (l 1'). As soon as one of the wires 8, owing to the rotary moremeat of the disks l0, ll has been brought close to the pressure rollers .l the bra he is put on, so that the rotation of: the cori'cspomliug spool 12 is retarded. and, us a camsequcwgex, the wire receives a considerable tension. 'Illhc. brake is put on with the assistance of a stop ill, which is secured to a rail 32 carried by the frame of the inacbii'ic. This stop ill, the bottom of which is suitably curved. projects down solar that the spring 29 passing there under is depressed and the respective brake block 28 accordingly pressed a rainsl; the spool. The stop 31 is so arranged that the spool 12 is still retarded some short time after the wires between the pressure rolls have been cut oil. Bf, this means the spool is prevented from being rctatcd further by momentum, which would cause the wire to become loose on the spool or entangled, and would occasion disturbances in the opcratimi of the machine. This. and all unnecessary unwinding of the spools, are prci'cnlwl by the action of the brakes.

In order to reduce the friction of the spring 21) on passing under the stop ill. rolls may be provided under the stop 31. as shown, for example. in Fig. 8.

As soon as a transverse wire 8 has been introduced between the pressure rolls, it. must of course be cut. oil. For this purpose the axes 34: of the rolls 1. are provided with circular cutters. the ope 'ation of which. will be evident from F which shows the particular part of the pressure rolls in front elevation. Fig. 10 is a section on the line ll-l? oil. Fig. 9.

Should it occur that. one of the wires is cut oil before it has been properly taltcu hold of by the pressure rolls 1 and fastcncd between the paper widths 2 and Il. said wire mightv los tension. Tliis must however be avoided. because otherwise the strength of the material produced would be impaired. Now the rotating disks 10. 11 are so arranged in regard to the pre sure rolls 1 that the wire is not cut: oil, until it is held by the rolls. It is however preferable to provide an auxiliary device consisting of? two disks 36 of rubber or other similarmatei'ial, which are provided on one side of the circular cutters on the axes 34- ot the rolls 1. 'lhesc disks have a somewhat larger diameter than the circular cutters 35, so that they come into contact. with each other in ad 'ance of the vertical middle of the rolls 1 and are thus somewhat flattened, as shown in Fig. 10. lletwccn these llattcned portions of the disk 36 the wire is held until it is fastened in position by the paper widths being stuck together. The same clicct. would of course be obtained. if a disk 36 of elastic material were provided on the axis of one of tl e circular cutters and press against the flange of the other circular cutter. The elastic disk would also be flattened by pres sure against the llange and thus hold the wire. A corresponding device preferably provided on the opposite side ot the pres sure rolls, in order to balance any differences in letting hold of the Wire. Instead of constructing the cutting device to cut the wires as soon as they arrive between the pressure rolls. said device may be so arranged as to out the u after they have left the rolls. For this purpose the cutters may, for (5X- an )le, be fitted on special axes behind the are rolls instead of on the axes of these latter.

The cinistructum and operation of the grippers carried by the disk 11, which, at a. suitable mon'xent, catch the free ends of the wires projecting through the nozzles is shown in Figs. 11-14. '11 is a radial section through the outer part or the dish 11 and shows the closed gripping device in side elevation. Fig. .12 is a section on the line lrl--ll of Fig. 1.1, Fig. 13, a plan, and let, a side elevation corresponding to Fig. 11, showing; the gripper in the open position. The wire is held between the ribbed jaw; 37, 38 of the gripper H. The upper jaw 37 is fastened to an angularly bent guide piece 39 and the lower jaw 38 to a guide piece 40, which has also an anp'ularly bent shape. The guide pieces 35}, l 1' n vertical guides 11, t2. which enable the paws to he opened by a movement parallel to each other. This movement is effected by a all 43, the back end of which rests in a fork ll provided on the disk ll, and is provided with a longitudinal slot -15, through which passes a bolt 46 carried by the fork i The front forked end ll of the rail 4-3 is jointed by a pin 4-8 to a rod 4-9, the other end of which attached to a disk 50 adapted to turnv about the pin A slot 51 of this disk tits on a pin attached to the guide piece 40 on the lower jaw 38, while a. second slot tits on a pin provided on the guide piece 539 oi. the upper jaw 37. If the rail is moved inward as far as possible (to the right according to Fig. 11) the link 49 will occupy a vertical position. and the two jaws 3T, 38 of the gripper will be closed. it however the rail 4-3 is moved outward (to the left according to Fig. 11) the link 4-9 and the di k connected thereto will be moved into an inclined position. As a consequence the lower jaw will be moved downward by the pin 52 and the upper jaw upward by the pin 54, so that the gripper will be opened, as shown in lfig. 14 The movement of the rail necessary to open the jaws of the gripper is obtained by a curve 55 secured to a cross rail of the frame over the disk 11. Against this curve 553 presses a roll 56 at thebach end of the rail 43. As a consequence the rail. at?) is pressed outward (to the left according to Fig. 11) and the gripper is opened. At the same time the springs 57 are bent, which at one end, are fastened to a book 58 attached to the rotary disk ll, and at the other end, to a pin 59 fastened to the rail 43. Between the open jaws the end of the wire projecting through the nozzle 13 can pass. Owing to the fun ther rotation oil the disk the roll. 56 passes oil the curve 55, whereupon the rail all will he moved inward by the springs 57 (to the right. according to Fig. 11), so that the jaws will be closed and the wire between them held fast. Said wire is thus held, until it passes between, the pressure rolls 1. At this moment. the roll 56 atthe lvacl; end. of the rail 43 will bear against the second curve 60. The rail 43 will be moved outward again, the gripper opened, and the wire accordingly released. As soon as the roll -56 lea ves the curve (30 the gripper closes again and remains closed until the roll 56, owing to the rotation of the disk again reaches the curve 55, whereupon the described operation will be repeated.

It now it should happen that the end of the wire projecting through the nozzle 13 does not take a horizontal position, but is bent somewhat up or down, it might occur that it will not pass between the jaws 37. 38, butslip over one of the same. In order to prevent this, there is provided in ad Vance of the point, where the gripper has to catch the wire, a guide 61, which is about concentric to the disk 10. This guide is shown in Figs. 1 -17 Fig. 15 is a side elevation, Fig. 16, a. plan and Fig. 17, a section on the line l--li of Fig. 16. The guide consists substantially of two parts 62, 63, between which there is an opening 6st. 'At their outer ends the parts (32, 63 are bent outwardly, as shown in Fig. 15. The opening 65, which is wide at the end and gradually decreases in width in passing into the opening (ll. causes the end of the wire projecting through the nozzle to be led, during; the rotation of the disks 10. 11, exactly between the jaws 37, 38 of the gripper 14. The disks 10, 11 are rotated by the spurwheels (36, 67 keyed to the axes of these disks. In the spur-wheel 66 engages'a spurwheel (38, which is rotated through the agency of. the bevel gearing 69 by the driving shaft 70, carrying the pulley 71. From the spur-wheel (i the motion is transferred to the spur-wheel 67 by the interu'zediate wheels 72 in such a way, that the two disks 1.0, 11 are rotated at the same speed, but in opposite directions.

The speed at which the cross wires 8 are fed to the pressure rolls 1 can be regulated.

not only by suitable construction of the gearing, but also by choosing a larger or smaller number of spools 12 on the disk 10 and a corresponding number of grippers 14 on the disk 11.

I do not desire to limit myself to the preill-5 else details of construction and arrangement herein shown and. described, as it is obvious that various uujidiliculions may he made therein without de 'iarting from the essential features of my lILVGlltlOIl as defined in the appended claims.
