at. the front end of the rolling. table and is picked up .thereby the operator and placed into a. pressing mould or meohanism. This use of half leaves causes,considerable'waste o fY tobacco, since generally a4 considerable Dartof each half leaf is not required. for the` binding of the tobacco filler. Furthermore the sizes of such tobacco leaf halves forming binders are variable, so thatthe size; ofthe finished cigars might differ. Therefore, it hasA been found advisable to cut out of, the tobacco leaf the part only4 that is necessary for the producing of the bunch binder, and to utilize the waste parts for other purpose. In other machines hitherto known this has been accomplishedby cutting the binder on av cuttingr die, from vwhich the binder is au.-

tomatically.` transferred to the :bunch rolling table. By the use of,r such a, cutting die and transfer the capacityof the machine has been increased `since the application of the tobacco leaf on; the cutting die and the cutting and removalV of thebinder from the die can take place simultaneously WithV the winding of a tobaccov ller into a binder previously delivered to the rolling table. Such improvements have been accompanied, however, by certain drawbacks that do not affect the simple machine to be served manually as described previously. Thus the automatically operating machine is expensive, and it cannot, easily befserved by a single operator, unless the finished bunches are transferred automatically from the bunch .rolling table to a suitable position convenient to the operator. Such` an automatic transfer would, however, make themachine still more complicated and expensive, Partly on account of the necessity of means for thev automatic transfer, partly because the, bunch thus transferred would have to. be pasted so as to prevent the (binder from getting loose of ther filler. Moreover, such pasting might deterioratel the product inasmuch as the adhesive (if not of a very high quality) may impair the taste of the cigarl when ignited.

`It is a main objectof my.present1 .inventicn t0` makeprovision for utilizingthe advantages; mentioned above and. avoiding.: the,` drawback, thus providing .a machine. in. the operation, ofxwhioh tobacco is savedfthe output of.. which. is high and which. can easily be servedby a singleoperator. Machines. of, the simple. and inexpensive, type previously, mentionedcan` easily be, rebuilt for that purpose.A It will notbe necessary to make radical changespof. the., constructions and. arrangements` of suchA machines. already., existing. iii-plants for the. manufacture .of cigars., Thus,. in. plants. in whichthebunch-` machines. are as-v sociated with juxtaposed bunch. compressingand wrapping machines... no. change ofL the.r elatv e positions, of said. machines. will be necessary, which; is very. important, particularly Where` suchV changeV might. beimpossible ,because the space islimited,

To thev accomplishmentof the,` foregoing and such other objects as. may. hereinafter appear, my invention. resides the; construction andl novel combination of parts. fully described here,- inafter, illustrated inthe accompanying draw.- ings, and. pointed, outA in, thewclaims appended hereto, it being; understood thatlvarious changes inthe form, proportionI and arrangement of the various parts. withinA the scope.` ofY the claims, may be resorted to Without departing `from the spirit of my invention.

Referringto. the drawings, the cigar bunch machine has. abunchi. rolling table VI upon which is4 placed abunchgrolling apron 2. In front; ofthe table l, relatively, near same,.is positioned a die. 3r for cutting voutgbinders of tobacco, leaves; takenV by. the operator at 4 from a supply on thetable 5 and placedupon theY cuttingdie. To cut thebinder, .tvvol cuttingl rollers B and; l'; are movable across the cutting; die 3, pressingupon its cutting edge 8 which is. positioned; obliquely relative to thedirection of. movement of the cutting rollers. Thecutting rollers 6 andglj are rotatably mounted each onV an armY 9; and; l0.,

respectively, and are rigidly connected each to a supporting roller 48 which is adapted to roll upon a bar II arranged slightly below the level of the cutting edge 8. The arms 9 and I0 are by means of tension springs 41 connected to an arm I2 which is pivoted to the arm 9 and provided with a rotatably journalled roller I3 which by the spring 41 is pressed against the underside of the bar II. The arms 9 and I8 are both pivoted to a lever arm I5 which is pivotally mounted on a stationary shaft I4. The lever arm I5 is by means of links and arms driven by a cam disk I1 which is secured to a rotatably journalled driving shaft I6. Thereby, the cutting rollers 6 and 1 are moved back and forth across the cutting edge 8.

rPhe cut binder is transferred from the cutting V die 3 to the bunch rolling table I by a binder carrier I8. The table I is perforated in its upper surface and interiorly connected to a suction conduit 48 which is also connected to the cutting die 3 and the binder carrier I8. As the suction surface of the binder carrier I8 is flat the surface I9 of the bunch rolling table upon which the binder is placed should also be flat. The flat surface I9 may, however, not be too wide, for then the bunching roller cannot satisfactorily enclose the bunch within the rolling apron 2, when it is moved across said surface I9 at some distance above same. Y Therefore, the extent of the surface I9 in the longitudinal direction of the bunch rolling table I is somewhat less than that of the binder, i. e. of the cutting edge 8. Therefore, the fiat suction surface of the binder carrier I8 at its corners 2I does not place the binder in tight engagement with the rolling apron 2. However, this does not cause any inconvenience since the apron is perforated so that it can transmit the suction effect from the perforated rolling table I when valve 3l is open and suck to the apron the ends of the binder projecting beyond the flat surface I8 when the suction in carrier I8 is destroyed by closing of valve 32 (Fig. 3). The tobacco llerplaced into the pocket 22 of the apron 2 is in usual manner Wound up by the bunch roller 2B and apron into the binder, and the Wound bunch A is by the apron introduced into a yieldable Aholder 23 at the front end of the rolling table I.

The binder carrier I8 is pivotally journalled on a hollow arm 24 which is secured to a rock shaft 26 which is rotatably journalled in a. bracket; 25. The shaft 26 is hollow and perforated so as to rcommunicate with the suction conduit 48. The shaft 26 is driven by an arm 4I, a link 42, a double-armed lever 43, a link 44 and a cam disc 45 which is secured to the shaft I6. In order Yto adjust the binder carrier I8 to direct its suction surface parallel to the sloping surface I9 of the table I, when the carrier is moved from the horizontal cutting die to the surface I9, a link 21 is pivotally connected to an arm 28 fixed to the bracket 25 and to another arm 29 that is slightly shorter than the arm 28 and is secured tothe binder carrier I8. The suction effect in the cutting die 3, the rolling table I and the binder carrier I8 are as usual created periodically by means of automatically operated valves 30, 3I and 32, respectively. The bunch roller 28 is rotatably journalled in the bifurcated end of a long lever arm 33 which is pivotally journalled on a shaft 24 that-is positioned at the bottom of the machine frame in a -plane extending transversely to the centre portion of the surface I9 and parallel with the shaft 26. The lever arm 33 is swung back and forth by a link 35 that is actuated by a cam disc 36 secured to the shaft I8. The shafts 26 and 34 are parallel.

The distance of the cutting die 3 from the front end of the bunchv rolling' table I is not greater than that required to enable the cutting rollers 8 and 1 to move past the cutting edge 8 to a position immediately in front of the bunch holder 23. After the cutting operation the rollers 6 and 1 return to their initial position (see Fig. 5) below the supply table 5. Therefore, the operator positioned at 4 can, over the cutting die 3, easily reach the bunch A in the holder 23, remove it from said holder and transfer it manually into a mould press of wood or a revolving mould drum of a cigar machine (not shown) mounted in the proximity of the cigar bunch machine. During such transfer the operator can hold the binder fast about the ller, so that no pasting is required to adhere the binder to the filler. A tobacco leaf can be picked up by theoperator from the table 5 and placed onto the cutting die 3 simultaneously as a tobacco filler is wound up into the binder previously cut out. Thus, as distinguished from known bunch machines of the main type to which this invention relates, the operator needs not be inactive and wait for the end of the winding process and the return of the bunch roller 28 before applying the binder manually. The operator usually occupied with the application of tobacco leaves on the cutting die can easily reach the finished bunch, take it out of the holder 23 and put it into a. press mould since the bunch is easily accessible over the cutting die. As no means are required for conveying the bunch to the pressing mould there is no risk that vthe binder will get loose of the ller when the bunch is transferred to the press mould. Therefore, no supply of paste to the binder is required. In order still more to facilitate the attendance to the machine the cutting die 3 may be movable up and down, so that it is elevated from a position of rest (shown in dash and dot lines in Fig. 4) into a. position, substantially at a level with the table 5, in which position a tobacco leaf is placed onto the cutting die. Thereafter, the die is moved down into the cutting position shown in dash and dot lines in Fig. 4, and the cutting rollers 6 and 1 are put into operation simultaneously as a winding operation takes place. For that purpose, the cutting die 3 together with its cutting edge 8 are mounted on a rod 31 which is movable up and down in the machine frame and driven by a lever arm 38 which is pivotally journalled on the shaft I4 and actuated by a cam disc 38 secured to the shaft I6.
