To all whom it may concern:

I 3e it known that I, HEN YIC. HUNTER, cltizen ofthe United States, residing at Jersey Clty, Hudson county, New Jersey, have invented'certain new and useful Improvements in Compounding-Machines for Manufacturing Paper or Pasteboard, of which the following is a specification;

My invention relates to a compounding machine by which a composite article is produced in the form of a' fiber board having an adhesive substance incorporatedwith the fibrous structure of the board and a label p sheet placed upon-the faceof-the board and united therewith bythe adhesive material.

By the use of my com ounding machine the composite article is ormed and cut at one operation, 'the'adhesive material being incorporated with the structure of the board,

30 and .the label sheet being immediately applied thereto, so that it will -bemade to adhere strongly and be dried flat upon said board'.

In the accompanyin drawings: Figure 1 represents a longitu inal sectional view through the machine. Fig. 2 is-ja detail view relating to the compounding roller. Fig. 3-. is a sectional plan view of the said roller. Fig. 4 isa transverse sectional View of. the compounding roller. Fig.- 5 is a detail' relating to the compounding roller. Fig. 5? is a detail viewo'fthe cutters. Fig.

. 6 is a detail-sectional vielw of a heated pressure roller for pressing'the labeland fiber sheets together. ig. 7 is asectional plan view of the upper series of pressurerollers and certain driving connections. Fig. -8 is a detail view of the adhesive rollers; Figs. 9 and 10 are detail views.

The machine comprises a feed table 1 upon which the fiber boards are placed.'

The label sheets which'are to be intimately associated with the fiber boards to make the composite article are preferably first placed upon an inclined feed board2. This table is hollow and is heated by steam introduced through a pipe 3 and escaping through a suitable outlet 4.. ()n this table the label sheets are piled and heated and; they are transferred from this storage table, one by one, to an inclined. feed table 5 which also may be heated, like the table 2 just menlioned,- by steam let in throughapipe 6 and roller the fiber boar escaping "through a suitable outlet. On

these two tables the label sheets are heated and are thus rendered, under certain circumstances, better condition for the subsequent fiClZlOIl'Of becoming united with the fiber board. The fiber board passes from the feed table 1 beneath the label feed table 5 to a compounding roller 7 where it receives upon its upper surface the edge of'the label sheet to be united thereto, both sheets then passing between the compounding roller 7 and its pressure roller 8, by which the label sheet will be applied accurately-throughout its whole extent to the fiber board as will,

be hereinafter. referred to. V

Previous to arrivin at the compounding" first passes through feed rollers 9, 10, and thence between 'the adhesive applying rollers 11, 12. 'The upper one of these rollers is driven by a belt wheel 13 thereon and it rotates at the bottom of a, fountain 15 so as to take the adhesive therefrom and grind the same into the fibrous structure of the board, so as to intimately incorporate the said adhesive with the fiber and form, as it were, a part of the board itself. In order to aid in this thorough incorporation of the adhesive substance with the fibrous structure of the board, the adhesive is ground before being applied to the board and for this urpose I use a roller 14 having slightly diff drential speed to that of the roller 12, bearing upon the said fountain roller 12 and forming therewith the bottom of the fountain. This grinding roller is set slightly at an angle'to the main roller, as shown in Fig. 8, as I find that the tendency of this roller, being smaller than the main roller, is to spring at its central portion away from the surface of the main roller and with a parallel arrangement of rollersthis allows the adhesive to pass through at this point in a greater quantity than at the ends of the roller and also without being thor-v deflected by the pressure, because of its size,

and when the middle portion of the smaller and weaker roller springs away the space between the rollers at this point will be the same as that between the rollers at their ends where the intermediate space results fr the angular arrangement of the roll 14 in respect to the roll 12, and thus a uniform film is delivered. When an adhesive is used .which is influenced or is soluble by heat the applying rollers 11 and 12 are heated similarly tothe pressure rollers to keep the adhesive in fluid condition.

When the fusible adhesive is already applied to the underside of the label sheet the fountain may be disused and the heat of the adhesive rolls 11 and 12 may be utilized to heat the fiber board and render it suitable for receiving the label sheet with its adhesive coating. Roll 14 is driven from roll 12.

The lower roll 11 is driven through gearing 16 from the shaft of the upper roll, and the lower feed roll 10 is driven through an idler; 17 and ear 18 from lower roll 11.

'After passing between the rolls 11 and 12 and receiving the adhesive substance, the fiber board rests upon the endless traveling apron or series of tapes 19 passing around rolls 20 and drivenin any suitable manner. This endless apron carries the board towards the rear of the machine until its leading edge strikes a series of register and stop pins 21 projecting up from the compounding roll 7 and disposed at different points along the same. These stop pins lie normally not only across the path of the fiber board but also across the plane-of the inclined feed table 5 for the label sheets, so that the operator in order to register the label sheet in relation to the fiber board and also in relation to .the cutting devices hereinafter referred to, simply feeds the label sheet against the register pins so that its leading edge will lie directly overthe leading edge of the fiber board. In order to support the said edge of the label in register with the leading edge of the board and ready to be pressed thereon, I employ a supporting plate 24 forming an extension of the feed table 5. It has fingers 21" bearing upon the register pins and it is secured to the under side of the feed plate by screws 22 passing through slots 23 in theextension plate and into the feed plate. This extension plate is retracted at the proper moment to allow the leading edge of the label sheet to-contact with the fiber board, and this retracting movement is etfected'by a lever 23, one at each side of, the machine, fixed to a rock shaft 24 suitably journaled in the frame and operated by an arm 25 from a suitable-cam on the shaft 26 journaled in the frame. The purpose of this extension plate is to furnish a temporary support for the leading edge of the label sheet while the same is bein properly registered in relation to the leading edge of the fiber board and the cutting devices, and when the board and label sheet have been properly registered against the pins 21 the tem orary support 24 is retracted'and the labe sheet at its leading edge is free to contact with the the label sheet upon the fiber board. This action takes place while the compounding roll 7 is stationary,'and as soon as the two sheets at their leading edges are pressed together by the pressure roll 8 the compounding roll 7 begins to rotate and carries the fiber board and the label sheet to the rear, the pressure roll 8 pressing the label sheet as it comes off the inclined table 5 down upon the fiber board. The compounding roll 7 makes a number of revolutions during the passage over it of the fiber board and during this time the register pins 21 remain retracted within the compounding roll as will be hereinafter described. In rear of the c mpounding roll, a series of pairs of heated p essure rolls 25 are arranged, between which the composite board passes after leaving the compounding roll, and by these pressure rolls the label sheet is pressed firmly upon and most intimately associated with the fiber board so that the article as it leaves the machine is of a substantially homogeneous structure, fiat and dry, the adhesive material being incorporated with the fibrous structure and the label sheet being closely united to the fibrous structure by the adhesive material.

After leaving the pressure rolls the composite board passes between a pair of cutter rolls 26 which cut the board into a number of strips exactly as registered by the registering pins and side guide a:, so that the printed design may be cut square and true in the same manner that an additional color would be registered thereon, the board being so registered that the cutters will operate be tween the designs on the label sheet, so that after leaving the machine the strips will be accurately cut as printed to the proper size for making the can tubes or like articles which carry labels on their outer sides. The cutter rolls are made up of circular cutting blades mounted upon a roller and are of ordinary form. In rear of the cutter rolls 26 I arrange a pair of delivery rolls 27. The pressure rolls are driven from the belt wheel 28 on the shaft of one of them and the members of each pair'of pressure rolls are connected by gears 29, while idler pinions 30 communicate the motion between the gears of the lower set of pressure rolls. The cutters are connected by gears 31 and are driven from one of the pressure rolls through an idler 32. The delivery rolls are also geared together, as at 33, and are driven through an idler pinion 34. All the rolls are suitably journaled in the frame of the machine as well as the idler pinions.

action which takes place in connection with this roll is the retraction of its register pins '21, for which purpose the said pins are carried by blocks 35, Figs. 2-4, arranged to move substantially radially of the rolland guided in ways 36, Fig. 3, of a stationary filling piece 37 within the said roll. The blocks have lateral-1y projecting pins 37" en tering inclined slots 38 in the slide 39', ar-

rangedto move longitudinallyjof the roll.

This slide, asshown in Fig. 4,'-is of substantially semi-circular form in cross section and is' fitted against the. filling piece 37. It'is normally pressed in one direction to hold the blockswith pins 21 'projectedfrom the roll, by means of a spring 40 bearing at one end against a block 41 fixed in one end of the roll and at its other end upon a shoulder 42 formed on the slide 39. The slidehas a phi 43, Fig. 3, at its end projecting beyond the end of the roll and in the path of a cam carried by a gear 45,'loose.on the journal 46 of the compound roll. Thisgear is rotated at proper intervals and its first action whenstart-ing from its, position of rest is to bring the cam 44 against the pin 43 of the slide and move the latter so that its incline slots working upon the pins 37 will retract the registering pins 21 within the compounding roll. As soon' as this is effected and the leading edge of the label sheet has been-- pressed upon the fiber board by the descent of the pressure roll 8 as will be hereinafter a groove across which the clutch pin 48 extends; This groove 50 is intended toredescribed, the compounding roll is set in rotation. For this purpose a clutch connection is provided between the gear 45 and the compounding roll, consisting-of a projection 47 on the gear and a clutch pini48, adapted to engage the same-and carried by a collar 49 fixed to the compoundingroll and having ceive a crescent 51 on the end of a lever 52 I loosely pivoted upon the main. driving shaft 53, as shown in Fig. 2.

The crescent controls the clutch1pini48 and when itis removed from groove 50 the clutch pin 48., will be forced by its spring 49,- Fig.{ :3, intothe path ofthe projection 47 on the =55 gear 45 which isnow in rotation-and consequently the compounding roll will be rotated int-unison with the said gear. This rotation takes place, as before stated, after the registering pins have been retracted and, in order to control this timing of the parts, the cresmotions arederived and thus easily kept in unison, the said cam acting upon a roller poundmg roll has ceased to rotate.

cam shown at 69 is representative suitable cams on the shaft 26.

cent carrying arm 52 is controlled by a cam on the shaft 26 from which all. automatic carried upon an arm 55 connected with the crescent arm 52. V I

After the fiber board and "label sheet have passed over the compounding roll, the rotation of the said roll is stopped and the register pins 21 are projected to stop and register the next fiber board and label sheet. For this purpose the crescent carrying arm 52 is moved by its cam to throw the crescent into the groove 50. The crescent has an incline 54, Fig.2, up which the head of the clutch pin 48 will now ride, thus retracting said pin from engagement with the clutch projection on the rotating gear 45, and as soon as-this disengagement takes place a pin 56 on the clutch collar will contact with the pin 57 on the crescent carrying arm and thus theroll 7 willbe arrested when its register pins 21 come exactly where wanted. After the compounding roll" is at rest the gear wheel 45 continues to rotate long enough to carry the cam 44 away from the pins 43, andfthis allows the spring 40 to exert itself to move the slide 39 longitudinally and project the registering pin by means of the incline slot and pin connection 38-37 before described. As soon as this has been accomplished the rotation of the gear wheel '45 is stopped for a predetermined length of time sufiicient to allQW the operator to properly feed and register the label sheet and fiber board, For this gear 58 loose on the main drive shaft 5.3 and purpose the clutch gear 45 is driven from a carrying a clutch collar 59 similar to that described above, the clutch pin 60 of which coiiperates with the clutch projection 61 on a clutch block '62 fixed to the main drive shaft ,53. This clutch is controlled by a crescent similar to that described above carriedon an arm 63 suitably pivoted on a bracket 64 on the main frame and'havin an extension 65 carrying a roller-engaged y a cam on the cam shaft 26. The gear wheel 58 is arrested accurately in the desired position by means of stop pinsj66 similar to those described. By means of this arrangement the gear 45 w1llbe given an intermittent movement, the

intervals between its actions being properly determined for the feedin in and registering of the label sheet an will'be seen that the said gear wheel 45 is started in rotation earlier, and remains in fiber board. It

rotation longer,'than the compounding roll,

its excess of movement being utilized to move' the register pins in and out after the com- The crescent levers are pressed in opposition to their cams. by means of springs 67, 68. The of any The pressure roller 8 is lifted positivel by a rod69 connected to an arm 70, whic is in turn connected to and operated by the crescent arm 63, the said rod 69' at its upper end is slotted as at71 and receives a pin on I fall by gravity as the register pins are retracted, so that the said pressure roll will follow the downward movement of the pins and will accurately press the leading edge of the label sheet onto the fiber board, this action taking place at just the moment that the register pins free themselves from the label sheet and fiber board. This lifting pressure roll 8 may be driven through suitable earing, but I prefer to let it remain idle, and I also prefer to control its weight by any suitable means of counter-balancing. As shown in the drawings the normal position of the register pins when projected and at rest is slightly to the right of the vertical axial plane of the compounding roll, the purpose of which is to insure a substantial contact of the pressure roller 8 with the label sheet. In other words, the leading edge of the label sheet is thus made to extend slightly'across the vertical axial plane of the compounding roll, so that the pressure roller will make a good contact therewith when it is lowered to a position directly over the axis of-the said compounding roll.

In order to control the feeding in of the fiber boards, I provide a stop 73 immediately in rear of the feeding-in rolls 9 and 10, carried by'a block 74 arranged to move vertically in a suitable guide way in the frame and pressed normally upwardly by a spring 75. The block is connected with a lever 76 pivoted at 77 and having a roller at its rear end acted on by a cam shaft 26.

-. The arrangement is such that, when the register pins 21 are projected and are in the position shown in Fig. 1, the forward stop 73 is down and the fiber board can be fed into the machine, but when the registering pins are retracted and the compounding roll is in action the forward sto 7 3 will be elevated to prevent the feeding in of a fiber board until the compounding roll has ceased to rotate and its registering pins have been projectedto arrest and register the label and oard, at which time the forward stop is lowered and the next board can then be fed in, or the exact relation between these stops and the registering pins-may be easily adjusted'by turning the cam on its shaft so that the board is made to come in at the right time to receive the new label sheet.

' The drive shaft 53 is. operated through a gear 78, Fig. 7, meshing with one of the gears 29 on the forward lower pressure roll. This gear 78 is loose on the shaft 53 but may be connected with the same to drive it by means of a clutch 79, Fig. 7, controlled by a lever 80 extending to any convenient point for operation by the attendant.

The cam shaft 26 is driven from the shaft 53 by means of a pinion 80 on the said shaft 53 and agear 81 on the cam shaft. All of the rolls as well as the apron or tapes 19 are driven at the same surface speed.

The pressure rolls 25 are'heated to better unite the label sheet with the fiber board and dry the same and also to assist the union when a fusible adhesive is used, and for these purposes they are formed hollow and into the ends of one of them, as shown in Fig. 7, a steam pipe 82 enters through a stufling box 84 arranged in the hollow journal of the said roll. From this roll the steam passes out through a pipe 85, the end of which is bent down as shown in Fig. 6, and is located at the far end of the roll from the steam inlet pipe 82. The pipe 85 passes out through the pipe 82 and connectswith an inlet pipe 82' of the next adjacent roll, which inlet pipe extends through a stufling box in the journal of the roll in a manner similar to that described above and through the whole system of rolls it proceeds similarly and is finally discharged through a suitable outlet.

In a similar manner the steam may be applied to the adhesive set of rolls to heat them when required or any convenient method of applying heat to all the rolls and tables at will and as the circumstances of the work requires may be used.

In Fig. 5 I show the preferred form of register pins consisting or a screw 86 threaded into a dove-tailed block 87 fitting in a recess 88 in the upper end of the block 35. The screw is surrounded by a clamping sleeve 89, the foot of which rests upon the upper end of the block.

It will be understood that I use the terms label sheet for convenience of description, as

it will be understood that the sheets'to be united with the fiber board may notalways carry a label.
