In carrying the invention into effect, there is provided a method of, and apparatus for,

cutting and applying a cigar wrapper to a cigar bunch. In the best practice of the invention the method includes-stretching a tobacco leaf section over a wrapper cutting bed with the edge which is to form the overlap on the bunch superstretched, then cuttlng out a wrapper from said leaf section,

and then applying the wrapper .to a ci ar bunch. vAll the apparatus that is essential to the practice of the invention is a cutting bed positioned with its overlap side nearer the operator and a wrapper carrier. unit arranged to take the cut wrapper and de-- liver 1t to a cigar bunch to be wrapped.

When an operator stretchesa tobacco leaf on the cutting bed, the leaf section L, as shown 1n Fig. 1, for'reasons explained below, is held with its far side raised so as to first make contact with the cutting bed D at the side nearest the operator who then slides the leaf across the bed in order to spread it as evenly as possible before laying the remainder of the leaf. As the central portion of the near edge of the leaf comes to rest on the cutting bed, it is held fast thereon by the suction connected to the bed casing and acting on the leaf through openings 0, so that the subsequent forward mo tion of the operators hands, shown by the vertical arrows in Fig; l, superstretches the leafL in the-direction of the horizontal arrows and causes the leaf to curve away from the operator, with the result that the far side of the leaf relaxes and, when out into wrapper'shape, often even becomes more or less wrinkled, according to the condition of the tobacco. But, even if the cut wrapper apparently lies perfectly flat on the bed, this curving effect of the progressive suctionhold is great enough to cause a considerable difference in the. tension between the forward and rear edge of the wrapper thereby producing a variance from its true shape.

VVith the'o rdinary position of the cutting bed, shown in dotted lines in Fig. 2, the loose orrelaxed edge of the wrapper, when applied to the cigar, forms the overlap edges of the turns, producing poor, partly open joints as shown in an exaggerated manner in Fig. 3. With the cutting bed reversed, as shown in full lines in Fig. 2, the superstretched edge of the wrapper forms the overlap edge of the finished cigar while the on the leaf from the flag end of the bed towards the tuck-end, and the portion of the leaf which covers the head-end, technically known as the flag, must be free of veins. In order to comply with these conditions on a cutting bed as ordinarily placed, Fig. 4:, the leaf section L must be gripped at its outer edge It and must be placed on the bed as far away from theoperator as possible, sothat the operator can watch the flag F while feeding the leaf and see that the same will be located on the bed withthe flag between two veins. This procedure brings the stem-edge S of the leaf section close to the 1 near side of the bed D 'andthus wastes the portion R of the leaf overhanging the far side of the bed, provided the overhang is notlarge enough to out a second wrapper.

With the bed r'eversed,Fig. 5. the leaf section L must also'be reversed so as to have the veins run in the proper direction, and the leaf section will thus be gripped at the stem side S, causing the latter to overhang when the rim-edge'R of the leaf has been val brought into: final-position .1 close .to the bed D. In this.case,therefore, the outer'or: thin part of f the ieafis use'd and Y the inferior stem-portion is wasted. 1

1 It has been sought to overcome the defects shown Fig. 3: by'theexpedient of cutting I the wrapper with its visible lappingedge substantially shortened from its true shape, so: that, in applyingthe wrapper, more than theprovided length is required: to fit properlyaround lthecigar; thereby taking up the looseness produced by the curving :of. the

leaf onthe die. But,' si11cetthe curving action produces varying :resultswithdifferent operators, with different-1 qualities of tobacco, and under different atmospheric conditions, this expedient only corrects the tron-- ble for the average case assumed in laying out the modified shape; when the curvature is greater than that assumed, the joints will still be loose, and when it is smaller, the Wrapper will be too tight and may tear at the laps.

The heavy dash lines in Fig. 2 show the :path of the wrapper from the cutting bed at F T to the starting positionFg T at the tuck end of the cigar bunch C in the wrapping mechanism. The flag end of the wrapper moves along the path F F F F making a part turn about its tuck end which at the same time moves along the path T T T T When it has arrived at F near the head or flag end of the cigar C, the'fiag end of the wrapper is carried along path F F .F F while the tuck end describes first a concave path T T and then a convex path T T From position F T the wrapper carrier returns in the reverse order, the wrapper being applied to the cigar bunch while moving from F T to F T from which point the carrier returns empty to the bed position F T to pick up the next wrap-v per. In the old position of the bed, the initial position of the wrapper is T F shown in dotted lines, the tuck end T taking the place of the flag end F and the flag end F that of the tuck end T To reach the position F T.,, from which the path of the wrapper must be the same as before so .as to pass along the cigar bunch in theproper positions for wrapping on its return path, the flag end moves along the approximately straight dotted path F F F F' and the tuck end along the dotted path Ti T T 3 T which joins the dash line path T T making a rather sharp turn.

The mechanism for performing the modified motion of the cut wrapper necessitated by the reversed position of the cutting'bed is as follows: The carrier unit is mounted on a hollow shaft 10 rotatable in the vertical bore 11 of a bracket 12 mounted on the bed plate 13 of the cigar machine. The upper end of shaft 10 is closed by a plug 14 while its lower end is connected by a pipe, not

respectively.

-17 v antd'l5uand shaft 10, withfithe suction apparatus referred to. The head 22 has the interchangeable bottom portion. 23 which is 5 formed to Sllit'i'llG shape .offthe wrapperto be applied and which is closedat its bottom by: the detachable carrier plate .24 provided 7 with rows ofisuitably'placed holes for..per-

mitting the suction to pick .up the cigar wrapper f-rem thec utting'bed'D when in position above thelatter. Theupperend of carrier head 22 is closed by. gear25 meshing with "gear segment 26 pivoted onstird 27 supportedbylug 28 of carrier arm '17.

' The extending end of segment 26 forms r the cam lever 29 carrying .cam roller '30. guided in cani 'track '31 of ia cam plate :32 mounted on carrierbracket 12. PCarrier arm. 17 has a cam levcr 33 carrying .roller 34 guided by cani track 35iof the cam plate 32. The lower endtofFhollow shaft 10.carries gear segment 36'meshing with gear segment 87 pivoted' on stud38' held'bybearing bracket ESQ-which is fasteil'ed to bedeplaterl3. Segment 87 is provided with a cam lever i0 cngagingby means of cam roller 41 in cam track42- of ca1n4'3 '.mounted.on the main drive shaft of. the lcigarx machine. In the operation of the machine for carrying .outrthe methodpthe carrier 23' must takelfthe cutwrappe-r from the bed D to the wrapper. applying position at the. tuck end ofthe cigar bunch C locatediu the wrapping device, must guide the wrapper along the cigar bunch While being wrapped and then goempty-toits initial position over the bed D,xalong thepath shown by the dashlines infFi'g: 2. This isaccomplished by. a combination ofthe turning motion of: hollow shaft 10 produced by. gearmsegment 37, of the pivotal movement of arni-17 produced by -cam lever33, and ofthe'turning motion of the .carrier head 22 by the. gear segment 26. Arm'15 onshaft 10 carries the pivot end. of arm-.17 alonga. circular path, while at'the same time. the 8111117 swings. around the moving pivot. and the carrier head 22 turns in the movingzfree end 21 of arn1f17;

allt-h ese movements being. guided by the cam tracks'3l, and 42 which are laid out for each-cigar shape to pjvethc carrier-head its correct position and proper speed at every pointof its path. The wrapper carrier is providedqvith. valves, not shown, which automatically control the suctionin the carrier head as required at the different stages of its motion. The carrier head 23 also communicates, through flexible pipe 44, with an air- I compressor, not shown, controlled by a valve which turns on compressed air to free the flag end of the wrapper from the 'carrier plate 24, in the position F T of the carrier head, at the moment when it leaves the nowfinished cigar C to return to the cutting bed for the next wrapper.

What is claimed is: 1. The method of applying a wrapper to a cigar bunch, which consists in stretching a leaf section over a wrapper cutting bed, superstretching the edge which is to form the overlap on the bunch, then cutting out a Wrapper from the leaf section so stretched and superstretched, and then applying the cutout stretched and superstretched wrapper in that condition to a cigar bunch, to avoid looseness at the overlap of the wrapper.

2. The method of applying a wrapper to a cigar bunch, which consists in stretching a leaf section over a wrapper cuttingbed, superstretching the outer edge of the leaf which is to form the overlap on the bunch, then cutting out a wrapper from the leaf -section so positioned and stretched and superstretched, and then applying the cutout stretched and superstretched wrapper in that condition to a cigar bunch, to avoid looseness at the overlap of the wrapper and T to avoid using the inferior part of the leaf section.
