Coincident ends of the rods have fixed thereto sprockets 55, over which are trained "chain section's' 56' for operating the sprockets whereby the plates are actuated-from their open or "upright positions, as shownfin dotted linesin Figure'3, to folded or horizontal positions as shown in full-lines, the

rearplate being disposed above the front plate. The ends V deposit onto the conveyor-and'whichreceptacle is provided'with'an open front end and bottom and

rear walls

61 and 62, respectively; A wrapper retainer 63 is secured in sliding engagement with thefrearwall 62 and has its upper end provided with an angled end section overlying the rear ends ofthewrappers-WJ The ends of the angled end section are equipped with blocks'in which are secured pins, one of which is illustrated at 64, having their lower ends relatively sharp and penetrating a plurality of the uppermost wrappers fora purpose hereinafter more fully described. 7 I i An'adhesive distributor overlies the wrappers W and comprises a reservoir 65 formed with apair of forwardly extending arms'66 fixed to' a supporting shaft 67 journaled in the brackets 31' and'on whichshaft is loosely mounted a pair of relatively fixed sprockets 68. The rear end of the reservoir 65 is provided with 'an'adhesive applying roller or applicator 69 constructed of suitable material, for instance, rubber, formed about and fixed to a drive shaft 70. The roller 69 functions to apply adhesive to the rear marginal area of the uppermost wrapper W disposed immediately subjacent the reservoir. The roller extends through an openingformed-in the bottom wall of the reservoir and is engaged by a distributor plate 71 adjustably secured to the bottom wall by means of screws extending through elongated apertures provided in the plate. The face of the plate, which engages the roller, is slotted, the slots being of a width and depth to permit a desired quantity of the adhesive A, contained in the reservoir, to be distributed by the roller onto the uppermost wrapper NV through the opening upon rotation of the roller. The shaft 70' of the roller is provided with a sprocket 72 connected to one of the pair of sprockets 68 by means of a chain- 73, the other sprocket of the pair being connected to a-sprocket'74 by means of a chain 75. The sprocket 74 is fixed to the shaft 32 whereby the roller 69-is rotated when the retaining belts are operated. Also fixed to the shaft 32 is a cam-76 for operating a cam arm 77 fixed to the shaft 67 and which functions to raise and lower therear end of the reservoir and roller out of and into engagement with the wrappers W.

In operation, assuming that plates 54 to be in open position and the roller 69 is disposed out of engagement with the uppermost wrapper which has previously been supplied with adhesive, the uppermost wrapper is grasped by the fingers of the operator and moved outwardly from the receptacle 60 and positioned upon the upper run of the conveyor between a pair of the flights and the plates 54 as illustrated in dotted'lines in Figure 3. As the uppermost wrapper is thus withdrawn, the rear corners are ruptured by the pins 64 to effect release of the Wrapper thus permitting the weight of the retainer to insure further penetration of the pins into another of the uppermost remaining wrappers for holding the latter during application of adhesive. When the wrapper has thus been disposed on the conveyor, a roll 30 is disposed within the wrapper and the treadle operated to actuate the plates to their folded positions as illustrated in full lines in Figure 3,

thus enfolding and sealing the roll the wrapper.

As the conveyor advances, the treadle is released to permit the plates to return to their open positions while the roll, which is now enfolded in the wrapper, is conveyed into engagement with the lower runs of the belts and retained As the conveyor and belts advance, the rolls are successively severed by the knife sections into relatively short lengths, thus, forming the toilet paper rolls or packs.

As diagrammatically illustrated in Figures 5 and 6 of the drawings, automatic mechanism may be employed for feeding the wrappers W from the receptacle 60 into position on the conveyor for wrapping about the rolls 30. The mechanism comprises a'pair of arms 80 each formed at its upper end with an angularly disposed section and wvith a longitudinally extending slot or track 81 terminating in a seat 82 in the section. The slots 81 have mounted therein flange rollers 83 journaled on the ends of a transverse hollow shaft 84 connected by means of a flexible tube 85 to a negative source of pressure. The

hollow shaft 84 has pivotly connected thereto and in 7 described. The lower ends of the arms 80 are connected together and provided with trunnions 87 journaled in the standards 24 and on which are loosely mounted pairs of relatively fixed. sprockets 88, one sprocket of each pair being connected to a similar sprocket 89, mounted on the upper end of each arm, by a chain 90 which is provided with a dog 91. The other sprocket of each pair 88 is connected to one of apair of sprockets 92 fixed to a shaft 93 also journaled in the standards 24. The shaft 93 has one end provided with a spur gear 94 meshing with a spur gear 95 loosely mounted "on a stub shaft 96 carried by one ofthe standards 24. The spur gear is fixed to a sprocket 97 also loosely mounted on the stub shaft and connected with a sprocket 98, fixed on the shaft 26, by means of a chain 99. One of the trunnions 87 has fixed thereto the upper end of a cam arm 100, the lower end of which is provided with a roller 101 engaging a cam 102 mounted on the shaft 26 of the conveyor.

In operation, assuming the cups 86 are in engagement 9 with the uppermost wrapper as disclosed in full lines in Figures 5 and 6,.and the conveyor shaft 26 is being rotated, the cam 102 serves to pivot and raise the arms 80 towards a vertical position and away from the receptacle 60 and with the chains 901being operated through the sprocket and chain assembly heretofore described. As the arms 80. arethus rotated, the uppermost wrapper will be detached from the other wrappers and moved outwardly from the receptacle. As the arms 80 continueto move away from the receptacle, the hollow shaft 84 will be engaged by the spring fingers 103 fixed to the brackets 31 and force the rollers 83 out of the seats 82, whereupon the shaft 84 and rollers 83 will be gravitated downwardly to the lower ends of the arms 80 and thus carry the wrapper downwardly. This action results in the wrapper being completely withdrawn from the receptacle and deposited upon the conveyor and between the plates 54 as shown in dotted lines inFigure 5. When the wrapper has thus been positioned, a valve (not shown), connected between the cups 86 and the source of negative pressure, operates to break the pressure and release the front ends of the wrapper from the cups whereupon a roll of paper maybe placed within the wrapper and between'the plates 54.

mit engagement of the cups 86 with the next uppermost wrapper for shifting the latter to the conveyor in the foregoing described manner.

From the foregoing it will be apparent that my invention provides a relatively simple and compact machine wherein the use of endless cutting bands for the severing of major rolls into short minor rolls is permitted due to arrangement of the bands with respect to the conveyor and retaining means.

Without further elaboration the foregoing will so fully explain the invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service. Moreover, it is not indispensable that all the features of the invention be used conjointly since they may be employed advantageously in various combinations and subcombinations.

It is obvious that the invention is not confined to the herein described use therefor as it may be utilized for any purpose to which it is adaptable. It is therefore to be understood that the invention is not limited to the specific construction as illustrated and described as the same is only illustrative of the principles of operation, which are capable of extended application in various forms and the invention comprehends all construction within the scope of the appended claims.
