Neumair, Hollis, N. Y., assignor to International Cigar Machinery Company, a corporation of New Jersey 1 Application September 18, 1934, Serial No. 744,597 Renewed September 4, 1937 24 Claims.

This invention relates to wrapping or enveloping machines, especially those wherein individual cigars are wrapped and sealed in transparent envelopes or wrappers formed of regenerated cellulose coated with athin layer of fusible moisture proofing composition, or similar material, so that the overlapping portions of the wrapper may be sealed together by fusion of the coating upon application of heat and pressure.

The main object of this invention is to provide an improved machine for producing a sealed envelope containing a cigar, and provided with a tear strip protruding .from the seam of said envelope, the package and method of making the same being disclosed in the co-pending application of H. A. Burns, S. N. 722,959, filed April '28,

A further object of this invention is to provide means for nicking the web of wrapping material to provide nicks on the outer seam edge ofthe wrapper blank at either side of the tear strip before the cigar is wrapped therein.

Another object lies in the provision of adjustability of the tear strip web feed mechanism to produce various lengths of tear strips. Still another object is to so arrange the device that the tear strip mechanism can be easily adjusted for different positions of the tear strip within the wrapper. Still another object is to. so construct thetear strip web feed mechanism as to enable its ready connection with a web feed control mechanism. With these and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations hereinafter fully described'and then specifically set forth in the claims hereunto appended.

These various objects are achieved. by the machine shown in the accompanying drawings in which:

In carrying the invention into effect there is provided a folder pocket, a web feed for feeding a Web of wrapping material in front of the pocket longitudinally thereof, means for feeding a tear strip. web in front of the wrapper web transversely of the pocket, mechanism for severing a wrapper blank and a tear strip from said webs and nicking one edge of the'wrapper web at either side of the tear strip web, a device for periodically advancing a row of articles and transferring an article sidewise from said row into the pocket, whereby the article is enfolded in the wrapper blank and the tear strip is held between the wrapper and the article, mechanism controlled by the advancing movement of the articles in said row for incapacitating said means when there is no article in position to be transferred to the pocket, folders for folding the Iongitudinal edges of the wrapper into overlapping relation with the nicked edge outermost so that the tear strip protrudes from the seam between the nicks of the outer wrapper edge, and means for sealing the overlapped wrapper edges to each other and to the tear strip. Inthe best constructions contemplated the tear strip feeding means is photoelectrically controlled to register printed areas thereon with the wrapper web. These various means and parts may be widely varied in .construction within the scope of the claims for the particular arrangement selected to illustrate the invention is but one of many possible concrete embodiments of the same. The invention, therefore, is not to be restricted to the particular construction shown and described.

The tear strip wrapping device hereinafter described maybe used in connection with a cigar wrapping or enveloping machine of the type disclosed in Patent No. 1,899,174, granted Feb. 28,

supported in bearings of a reel-holder bracket ll adjustably secured to a horizontal supporting bar l2 adjustably fastened to brackets l3 mounted on main frame It of the wrapping machine. The

tear strip web I is led over a guide roller l5- revolubly mounted in the bracket H, and is pulled off reel 5 by means of a feed roller l6 splined to a shaft ll slidably mounted in lugs H of bracket ll and bearings IQ of brackets 25 and 20a (Fig. 1) attached to supporting bar It. A tension roller M (Fig. 2) presses the web '1' against feed roller it and assures good traction of the latter on the web '1. Roller 2i is pivoted in a pair of arms 22 loosely mounted on shaft 23 supported in bearings oi lugs id and a hearing it of bracket flu. Arms 22 areprovided with tension springs 25 anchored to the adjacent lug l8, whereby the roller 26 presses web '1 against feed roller it. It will beobseived from the following description that the adjustment of bracket H and bar it will, resprctlvely, vary the position at which the tear strip is enfolded in the enveioped cigar and increase or diminish the lengthof the tear strips severed from web I.

In order to control its feed in such a manner that prints or designs on the web T will appear in the same relative position on all tear strips severed therefrom and the enveloped cigars in, in which the tear strips are enfolded, the tear strip web T is led between a photoelectric cell 26 (Fig. 2) attached to holder bracket ll and a lamp housing 260. containing an incandescent lamp arranged to project a beam of light through the web T onto the photoceliZB. The photoelectric cell 25 through wires 21 (Fig. 1) is connected with the grid of a thermionic valve (not shown) in a control box 2% (Fig. 1), the anode circuit of the thermionic valve being connected to a relay which controls the circuit in the wires 29 through an electromagnet 3d attached to bracket 39 mounted on main frame it, and the filament of the thermionic valve, the photocell 26 and the wires 29 being in circuit with the supply mains 32. Control box 2d contains all the elements of an electrical clutch control mechanism such as shown in Fig. 5 of Patent No. 1,998,069, granted April 16, 1935, on the co-pending application of R. J. Beutel, S. N. 611,909, filed .May 1'7, 1933, including a commutator C (Fig. '1) connected in series through the relay to the line it and also connected to one of the leads 29 and acting to break the circuit through the electromagnet 30 after the same has been closed by the relay.

With the passage of a printed design D on the tear strip web T through the light beam projected onto the photoelectric cell 26 the latter will be dark and it passes no current and hence the grid potential of the thermionic valve will be changed so that sufllcient current flows in its anode circuit to energize the relay and close the circuit through the electromagnet 30 whereby the latter is energized and attracts an armature plate 33 attached to a sleeve 34 loosely mounted on shaft 35 (Figs. 1 and 6), supported in bearings of main frame It.

Sleeve 34 carries a vertical stud 36 (Fig. 6) which engages with arm 31 of a double lever 38 pivoted to a lug 39 of pedestal l3. The other arm of double lever 38 is equipped with an operating plate Ml facing the end of the tear strip web feed drive shaft II. On the latter is mounted the clutch member or disk 4| (Fig. 1) engaging with the clutch member or disk 2. Clutch member 42 is mounted on a housing carried by a,

drive shaft 43 intermittently rotated in one direction only through a ratchet 44 and a spring pawl 45 from an oscillating gear 46 driven by a reciprocating gear rack 41 connected to a web feed controlmechanism F of the general type disclosed in Patent No. 1,875,974, granted September 6, 1932, on the application of T. W. Alm, which is operated by means of a cam lever (it I fromthe main drive of the wrapping machine.

- Feed shaft ll is equipped with a collar 49 (Fig. 1) and a compression spring 55 to keep the clutch members engaging during the feeding operation. As soon as the beam of light thrown onto the photoelectric cell -25 is intercepted by the prints or designs D of the tear strip web T, the electromagnet 30 is energized and attracts armature plate 33, whereupon the lever 38 presses the operating plate Ml against the end of shaft ll, causing clutch member (ii to disengage clutch member 42 and thereby stop feed roller IS. The latter is splined to the shaft ll by a key M (Fig. 1) slidably engaging in a keyway 5?.

of shaft H. In this manner the feeding of the web T is interrupted until the circuit through theelectromagnet 30 is broken by the commutator C, whereupon the feeding of the web T is resumed. While the photoelectric cell is illuminated by the beam of light projected thereon through the web T it passes a current which opposes the grid current of the thermionic valve and thus reduces the same sufi'iciently until there is no current in the anode circuit. The relay is then no longer energized to close the circuit through the electromagnet and latter is thus maintained ina deenergized condition until the light beam is intercepted by a printed areaof the web T.

After passing feed roller it the tear strip web T is led through a vertical guide 53 attached to lugs ill. Guide 53 is provided with a concave channel 54 (Fig. 7), the shape of which will minlmize the friction of the tear strip T while pass- I ing therethrough, and serve to increase the stiffness of the free end of the tear strip web T, thus assuring that itwill be fed into position to be enfolded in the enveloped cigar.

To guide 53 is attached a knife holder bracket 55 on which is mounteda stationary ledger plate 56. A swingable knife blade 51 is pivoted on stud 58 set in bracket 55 and disposed obliquely of the tear strip web T to form a pointed tab on the severed tear strip. Knife blade 51 and stud 58 are connected by means of a torsion spring 59 (Fig. 1) for the purpose of keeping blade 51 while it is at inoperative position, in contact with the adjusting screw 60 of the knife operating lever (ii. The latter is fulcrumed on a stud 62 (Fig. 2) set in one of the lugs I8. Arm 63 of the lever 6l carries a cam roller 66 engaging the plate cam 65 mounted on oscillating shaft 23. Roller 6B is held in engagement with cam 65 by means of a tension spring 66. Shaft 23 carries a gear El (Figs. 1 and 2) which is actuated by means of a reciprocating gear rack lid guided by the roller 69 (Fig. l) and connected to an operating lever Hi mounted on a rocker shaftnicking the outer seam edge of the wrapper web W at either side of the tear strip web T in order to start the tearing of the wrapper when the pointed tab on the protruding end of the tear strip T is pulled, after the same has been enfolded in the enveloped cigar, to remove the wrapper from the cigar. To the back of guide 53 is attached a ledger plate 13 (Fig. 2) through the slots of which the nicking knives 12 will pass during the nicking operation, thus assuring clean cuttingof the nicks.

The wrapper web W is fed from a roll R by means of a web feed of the type shown in the Patent No. 1,796,073, granted March 10, 1931,

on the application of R. J. Beutei, comprising a pair of rollers 14 (Fig. 1) into horizontal guides 15- attached to main frame I4, and a desired length of wrapper is cut off therefrom by means of a knife 18 actuated from the main drive of the wrapping machine in the manner shown in said Patent No. 1,796,073. R011 R is supported by a stub shaft 11 loosely mounted in a bracket 18 fastened to main frame l4. Feed rollers 14 are driven intermittently by means of a bevel gear 19 (Fig. 1) meshing with a bevelgear '80 fast on shaft operated by means of the rack F of the wrapper feed drive and control mechanism F (Fig. 3), the rack F being gearex o shaft 35 to turn it one direction only.

The cigars to be enveloped are advanced sidewise in a row on a table 8| (Fig. 2) with a stepby-step motion by means of pusher fingers 82 .towards a pair of oscillating transfer arms 83 out tear strip T andwrapper blank W (Fig. 2)

into a turret or folder pocket 84, the cutting of the tear strip T taking place as the cigar in arms 83 touches the strip T and wrapper blank W. After the cigar with the tear strip and wrapper is pushed into folder pocket 84, a folding plate 85 moves upward and folds the lower outstanding edge of the wrapper W and strip T onto the cigar. The other longitudinal edge of the wrapper is folded over the inner ,edge by means of a stationary folding plate 88 as the turret advances in the direction indicated by the arrow in Fig. 2, the pointed tab of thetear strip pro truding from the seam so formed, between the nicks of the outer seam edge. Stationary folder plate 88 is attached to main frame l4 and folding plate 85 is vertically oscillated by means of a pair of levers 81 operated from the main drive of the machine. c

In case the pusher fingers 82 fail to advance a cigar into position to be transferred to the folder pocket the control "mechanism F will be incapacitated in the manner shown in the Aim Patent No. 1,875,974 referred to above, thereby temporarily. stopping the wrapper web and tear path of the cigars being advanced by the pushers 82 and connected to linkage (not shown herein) carrying a knock-out screw (not shown) which engages the tail of a latch lever (not shown) pivotally mounted on the rod F connected to the collar F loosely mounted on the rod F, unless the feeler is pushed back by an advancing cigar. The collar F is pivotally connected to the lower ends of the racks 41 and F wherefore the absence of a cigar in the row of cigars being advanced by the pushers 82 will cause the latch:

a pawl 88 acting upon a ratchet 89 mounted on shaft I'I. Pawl 88 is equipped with a spring 90 urging it against the ratchet 89 and provided with a pin 9| projecting over a stationary cam 92 having its hub loosely mounted on shaft l1. By means of a set screw 93 the cam 92 can be fastened to shaft I! in any desired position to control the feed for the. length of tear strip T desired. As soon as pin 9i rides onto the high portion of cam 9 pawl 88 disengages' from ratchet 89 and th eby arrests the tear strip feed. Reciprocating gearrack 41 is always held in engagement with oscillating gear 48 by a guide roller 94 pivoted to the rear portion of bracket 28.

While the invention hasbeen illustrated in connection with the cigar enveloping machine shown in the ,Wheeler PatentNo. 1,899,174, it will be understood that the invention may be applied to cigar enveloping machines of other types, such as that shown in Patent No. 1,964,411, granted on the application of R. J. Beutel. With the latter machine, when regenerated cellulose coated with a thin layer of fusible material is used for the wrapping material and the tear strip web, the overlapped wrapper edges will be heat sealed to each other and to the end of the tear strip protruding from the seam. so formed. One advantage resulting from the union of the tear strip and thewrapper edges is that when the tabof the tear strip is grasped to tear open the wrapper, the tear strip cannot be pulled out from "between the wrapper edges without rupturing the wrapper as in prior arrangements in which the overlapped wrapper edges are unsealed.

It will also be understood while the invention has been described in conjunction with cigar enveloping machines, it may be applied to candy. bread, and chewing gum wrapping machines, cigarette packaging machines and the like.
