The present invention relates to a `method l narrow band asa rule, must be visible on the 1 imposed upon the tax band-one must be ydisplaced from the other so thatone edge ofthe' tax bandwill be visible. Y l

Formerly banding with two diierent bands was accomplished by having the band applying device operate with two magazines of' bands,

the device drawing a band from one magazine.

and applying it and then being shiftedto draw a band from the second` magazine andapplying it over the rst. Such a device is not only com-f plicated in construction and delicate because of the various motions it must have, but itis slow. A single cigar. must remain in the region of the banding devicev while the deviceperf. forms two' operations. vi

A considerably more rapid and satisfactory method of banding rwith two diiierent'bands is to employ two banding devices of similary .con-` struction and move the cigars successivelypast 30 them. One of the -devices applies the first' bandf and the second applies the second band.

The presentinvention has for its object to provide means whereby two similarly constructed banding devices may be used'to apply 35 two bands in partly overlapping relation. f

Another object is to provide means in which two bands of different widths may be applied in the desired relation on a cigar.`

A further object is to provide a continuous banding device to accomplish the ab'ove'named objects. v

Another object is to provide a method of peration for use in applying two or more super imposed bands on a cigar in partly overlapped relation. Y y

In general the Ainvention is carried out by moving the cigar past two similar banding devices and eiecting, after the iirst band has 'been applied, an axial displacement between the cigar and the second banding device. In one forni .of construction this effect is produced by having the second banding device of a shorter amplitude of movement than therst whereby the second band is placed nearer to the end of the cigar than the rst byv anamount sufficient so that The presence of a1 A portion of the tax band,v which is acigar so that if the ornamental band be supera portion of vthe underlying band will remain visible afterthe upper band is applied.

Another construction to accomplish the purpose consists in' locating one of the banding devices closer to the path of themoving cigars than the other whereby the same amplitude of movement places the bands in different positions on' thev cigar. Althird type of construction involves the displacement of the cigar itself after it leaves-the first banding device.

With 4the foregoing and other objects in View, theinvention will be more fully described hereinafter, .and will be more particularly pointed out ,in the claims `appended hereto.

Referring now to Figures 1 and 2,12 represents avvork4 table which is provided along its length with a pair Yof slots 2 in which operates an inter-f mii-tentY conveyor l which has troughs or cradles 3 atspaced points to receive cigars Z. Thisconveyor is driven in any of a'number of well known manners to produce a vstep by step advance of the cigars along Ithe table in the direction. of the arrow in Figure 1. The cigars Z are held in linev by means of a guide 8 which runs parallel to the conveyor I. At spaced points along the conveyor |-the band applying devices 4 andl 5 are located. These devices are shown in dotted lines in Figures land 2 and areof well understood construction. For instance the band applying devices may be of the type shown in the patent to Malocsay No; 1,261,831. It will be noted from Figure 1, that the band applying device 5 isr nearerto the left run'of the' conveyor I than is theband applying device 4. Opposite the device 4' is ka feeding head 4' which, as is well known, is constructed of hollow arms connected at one end with a vacuum pump and open at the other end, as foi-instance, is shown in the Malocsay Patent No..v 1,261,831. The ends of the head 4', nearest to the conveyor rl, are upturned and open. The

head 4' is carried by `a bracket 20 which is secured pivotally to the top of an arm 2|. The bracket 20 is likewise pivotally secured to the top of an arm 22 which as shown is of adjustable length. The arm 2| is pivotally secured to a shaft 23 running lengthwise beneath the table 2. This arm 2| moves the bracket 20 and head 4 into and out of the path of the cigars. The required motion is produced by the rotation of a shaft 24 carrying a cam disc 25 against which bears a roller 26 on the arm 2|. The roller 26 is yieldably pressed against the edge of the disc 25 by means of a. spring 21 secured at one end to the arm 2| and at its outer end to the bracket 28 fastened to the table 2. As the shaft 24 is rotated the arm 2| swings about the shaft 23 and advances the head 4' to a position beneath the banding device 4. The head 4 is rocked in a vertical sense by means of the adjustablearm 22 which is pivotally secured at its lower end to a yoke 29 pivoted on the shaft 23 and carrying at its opposite side a short arm 30 which'carries a' roller 3|. A smaller cam disc 32 fixed to the shaft 24 provides the motion for the arm 30 and the adjustable arm 22. The roller 3| is retained against the edge of the disc 32 by means of the spring 33 fastened at one end to the short arm 30 and at its opposite end to the table 2. It will be seen that in the position shown in Figure 2 the roller 3| is riding on the highest point of the disc 32 and the head 4 is in its uppermost position against the bottom of the stack of bands Zu' which-areheld in the'magazine 6. This .magazine, as is well known, is open at the bottomand the open upper ends of the head 4 are applied against; the surface of the lowermost band Zu. For example of the details of this structure see Malocsay Patent No. 1,261,8311.4 'Ihe suction in the head 4 is suflicient to pull this lower band 40 away from the stack when the'head 4.' is` moved downwardly as the roller 3| rides downA on a lower portion of the cam disc 32. The band Zu' is thenY carried with the head 4' out beneath the applying device 4 which wraps it and secures it 45 about the cigar Z. V

The band applying device 5 has located` opposite it a feeding head 5' of identical structure with Ythe head 4. The head 5 moves in the direction of the cigars a shorter distance than 50 the head 4'. The amplitude of movement of the head 4 isA indicated by the length line marked X` in Figure 1 while the 'amplitude of the head 5 is indicated by the length line Y. The shortening of the stroke of the head 5 is accomplished by 55 reducing the maximum diameter of the cam disc corresponding to the disc 25 associated'with the head 4. Such a reduction in diameter is indicated in dotted lines in Figure 2.

The movement of the conveyor I and the oper- 60 ation" ofthe heads 4 and 5' and of the band applying devices 4 and 5 is timed so that a cigar isV placed in front of Teach of the devices and stopped long enough for thedevices to perform theiroperations and then the conveyor moves 65 suffcientlyto place a subsequent cigar opposite each of the devices. 'Such synchronous operation of the conveyor, the band feeding, and the band applyingunits'is well-known in the art and may be accomplished by adopting a driving mechanism 70 such as shown in the U. S. patent to Schmiedel No: 2,065,029.` The structure above-referred to forms no part of this invention or the claims directed thereto. In this way, the operation of the banding machine 'is constant and the second 75 band is being applied to one cigar as the'rst is second band applying devices.

being applied to another; thus, only the time of a single banding operation is consumed. In the drawings the first band, usually the tax band, is indicated by Zu and held in the magazine 6. 'I'he second band Zu" is the ornamental or identifying band and is held in the magazine 1. The ornamental band Zu is placed nearer to the round end of the cigar than the tax band by an amount sufficient to leave a substantial portion of the tax band visible. The magazines I5` and 1 and the feeding heads 4' and 5 are placed on the table 2 in line with one another, that is, they are spaced equal distances from the conveyor I.

` The only difference in the devices is that the band applying device 5 is nearer the left hand run of the conveyor than is the band applying device 4 and the stroke of the feeding head 5 is shorter as explained.

Figures 3 and 4 illustrate the second form of construction. In this construction identical band feeding heads 4 and 5'vare used. The stroke of each also is the same, the cam disc of the feeding devices being identical. The variation in the position at which the band is applied is obtained by locating the entire feeding head assembly 4 nearer to the left run of the conveyor I than the feeding head assembly 5'. The band applying devices 4 and 5 are located as in the previously described form of construction shown in Figures 1 and 2. Figure 4 shows clearly the lateral displacement of the magazines 6 and 1, the magazine 1 being further away from the ends of the cigars than the magazine 6. The result of this construction is that the same magnitude of stroke in the two feeding heads 4' and 5 produces different positloningsfof the bands Zu. and Zu upon the cigar. s

Referring now particularly to the thir'd form of construction as shown in Figures 5 and 6, the band applying devices 4 and `5 are shown directly inline with regard to the conveyor I. The feedirgheads 4' and 5' togetherwith their respective magazines 6 `and 'l are likewise located in the same longitudinal line on the table 2. In this construction the cigar itself ismoved before the second band is applied. The cigars are held in line at Vthe end of the table 2 adjacent the band applying device 4 by means of a short guide rail I1 which ends somewhere between the rst and After the end of the guide` rail I 1 another short guide |8 is located on theV table at a point further removed from the conveyor Opposite a portion of the guide` I8 a pusher 9 is located and synchronized with the conveyor and the band applying device so that when the cigars stop it pushes one of them against the guide I8 thus shifting it lengthwise before it arrives opposite the second banding device 5. As shown in Figure 6 the pusher 9 is composed of a rod 9' slidably mounted in a pair of spaced blocks I0. 'I'he end of the rod S opposite the cigars extends over the edge of the table 2 .and carries a pin 34 at one side. A bell crank lever II is pivotally mounted on the table 2 by means of the pivot I2. At its upper end the lever II' carriesI a yoke 35 which fits around the pin 34 and transmits the motion of the lever thereto. At its lower end the lever II'carries a roller I3 which plays against the edge of a cam ldisc 36 and against which edge it is held by means of the traction spring I4 attached at one end to the lower arm of lever I I and at the' other end to a portion of the table 2. rI'he disc 36 is mounted on they shaft 24 with the discs controlling the feeding heads 4 and 5 and rotates with them.

At the same time that the feeding heads advance a band over a cigar the pusher 9 advances against the end of a cigar Vadjacent to it and shifts it by an amount'sufcient to place it against the guide I8. The amount of this movement issufflcient to produce the desired displacement of the second band Zu awayfrom the first band Zu'.

The invention above described is not limited, ofcourse, to the particular bands applied but the need for spacing the tax band and the ornamental band of a cigar forms one useful purpose to which the invention may be applied. In its broader sense the invention consists in employing banding devices of the same type at spaced points. The cigar is moved past the banding devices and some time before the rst and the second of said devices a shift lengthwise of the cigar is produced between the position of the rst band and that of the second.
