OTTO HESSER, OF CANNSTADT, GERMANY.

PAPER-BAG MACHINE.

SPECIFICATION forming' part of Letters Patent No. 643,843, dated February 2o, 1966.

Application filed May 25,7`1896. Serial No 592 ,985. (No model.)

To all whom t may concern:

Be it known that I, OTTO HESSER, machine manufacturer, a subject of the King of )Viirtemberg, residing at Cannstadt, in the Kingdom of Wrtemberg, Germany, have invented a certain new and usef ul Machine for Making' Paper Bags and the Like, of which the following is a specification.

My invention relates to improvements in machines for making paper bags and the like.

This invention has for its object to enable paper bags and the like (more particularly paper bags with bottoms) of any suitable form and size to be made on the same machine, also to enable the mandrel, foldingbox, longitudinal folder, bottom-folder, and gumming-stamp of the machine to be changed or adjusted according to the form and size of the bag to be made, while the various other parts of the machine may remain for all sizes and forms of bags.

My invention consists in the features, details of construction, and combinations of parts, which will first be described in connection with the accompanying drawings and then particularly pointed out in the claims.

In the drawings, Figure 1 is a plan view of a machine embodying my invention; Fig. 2, a detail plan view showing the driving-shafts and gearing; Fig. 3, a longitudinal sectional View; Fig. 4, a transverse sectional view; Fig. 5, a detail plan view with some ofthe mechanism removed; Figs. 6, 7, and 8, detail longitudinal sectional, transverse sectional, and plan views, respectively, illustrating the blankfeeding devices; Fig. 9, adetail side elevation illustrating the folding mechanism; Fig. 10, an end view; Fig. 11, a detail side elevation taken from the side opposite that shown in Fig. 9; Figs. 12, 13, and A14, detail views of the folding mechanism; Fig. 15, a transverse sectional view showing particularly the pasting mechanism; Fig. 16, a detail plan view, also showing said pasting mechanism; Figs. 17 to 24, inclusive, diagrammatic viewsillustrating the steps of procedure in folding the bag; Fig. 25, an enlarged detail view showing the manner of discharging the completed bag; Fig. 26, a detail view of the means for driving the gumming-roller; Figs. 27 and 28, detail views of the gum-applying stamps and their attached parts; Fig. 29, a detail view showing the manner of securing the table O to the bed-plate A; Figs. 30 and 31, detail views of the mandrel and its adjacent parts; and Fig. 32 shows two views of the cam mechanism for vibrating the lever F2, which moves the stamps into and out of position. Fig. 33 is an enlarged side view showing modifications in the arrangement of the bottom-folders. Fig. 34 is a vertical part sectional elevation thereof, taken substantially at right angles. Fig. 35 is a similar view to Fig. 33, taken from the opposite side; and Fig. 36 is a plan view of Fig. 35.

The paper blanks Z, (see Fig. 1,) which have been previously stamped out into a suitable form, are placed on a carriage B, which has an intermittent reciprocating movement and between the two rails of which there is arranged a fixed table O, fastened on the bedplate A of the machine. The said table C is secured to the-bed-plate A by means of legsl c3, which are secured to the table and to the bed-plate A in any suitable manner, as by bolts c4, passing upward through the bedplate A and screwed into the table C, as shown in Fig. 29, the legs c3 being tubular.

` In one movement of the carriage B, which is carried by rollers b', Fig. 4, the paper blanks Z are conveyed from the first station I (on which they are placed) onto the first haltingplace Il, where the sheets are gummed at certain places and retained on the immovable table C by means of a plate d, carried by an oscillating arm D. On the return of the carriage B this plate d holds the sheets fast on the table C until the next forward movement of the carriage, when a fresh blank Z, which has been placed on the rst station I, is conveyed to the gumming-station II, while the blanks Z, which have already been gummed, are released by the arm D and conveyed from station II to the next station III, and there again retained on the table O by another similar device d D on the return of the carriage.

In this manner the paper blank Z is gradually conveyed to stations IV and V. In this latter station the blank Z is folded into a shitable form on the mandrel L and the open sides, as well as the bottom, are stuck down. From station V the finished bag is then pushed (at right angles to the previous course of movement) off they mandrel L and conveyed to the IOO next station VI, where it is prevented from returning with the ejecting-rod by an elbowpiece placed in front of its open edge, and is subsequently pushed overa beveled block V.

Stations III and IV have no further object than to give time for the gum to dry-z'. e., to become viscid.

The operation of the carriage B, as well as of the variousoperatingfdevices which are necessary for the conversion of the paper blank Z into a bag Z with a bottom, is effected by means of suitable peculiarly-shaped cams 1 to 15. These are mounted on two parallel shafts A/ and As and a cross-shaft A2, Fig. 2, which three shafts are mounted in bearings or brackets a on the frame under the bedplate A. The shaft A is driven by means of a friction device from the belt-disk E3, while the shafts A2 and A3 are driven from the shaft A by means of bevel-gearing a.

As already mentioned, the table C is fixed stationary on the plate A. The forwardingcatches b are arranged on the carriage B (see Figs. 6 to 8, Sheet 2) and are beveled off at the rear and have recesses in front in which the blanks Z are laid. On the carriage moving` forward these catches b carry the blank Z with them and bring it to the next stoppingplace. In order that the sheet may not be carried too far on the stopping of the carriage B, elbow-levers C are arranged beneath the fixed table C, and are each provided at both sides with two small adjustable an gle-pieces c, which encounter and retain the blank. These elbow-levers are coupled at their other end with a lever c2, Fig. 3, by means of a common rod c', which lever c2 is mounted in a bracket C2, fixed to the bed-plate A, and receives its movement from the stopping-cam 2, Fig. 3, by means of the rod C3, connected therewith.

The carriage B, which is carried by the rollers b', is connected by means of an elbowpiece B' and link b2, pivoted in sockets b thereon, with an operating-lever B2, which is mounted on the rock-shaf t a2 of the frame and receives an oscillating motion from the cam l, mounted on the cross-shaft A2, by means of the rod B3, connected with it, and transfers this movement to the carriage B. As soon therefore as the carriage B makes a forward movement the elbow-pieces C are turned so far that the angle-stops c project above the table O and come in contact with the blank Z. The retainer-plate d then immediately presses the blank Z down onto the table C and holds it fast. The elbow-levers C then turn back again, and the stops c disappear under the table. On the return of the carriage B the catches b, which are beveled or tapered in the rear, slip Linder the paper blanks Z, which are held down by the retainers, lift these sheets, and then slip away under them. Before the forward movement again takes place the retainer-plates dare raised by means of the arms D and release the blanks Z, and the latter are then on the next forward movement further forwarded to the next stopping-place.

The retainer-arms D are mounted on a common shaft D', Fig. 1, and are operated by means of a lever d', fixed to the latter and rod D2, Fig. 15, from a cam 3, which is mounted on the parallel shaft A3, Fig. 15.

The arrangement at the station II, where the sheets are gnmmed, consists of gummingstamps H, H', and H2, Figs. 15 and 16, adj ustably mounted on a plate F5, as is obvious from Figs. 27 and 28, which is detachably connected to a sliding piece F, which latter is moved on guide-barsf by means of a rod F', connected to a lever F2, which latter receives movement by means of a rod F3 from a cam device 4, which is operated by the shaft A, which cam device consists of a collar 1, fixed on the shaft A and rotating Within a link 2, secured to the end of the rod F3 and carrying at each end a roller 4, said rollers being on opposite sides of the said link 2. At each side of the collar la is secured a cam 4b, these cams being Secured to the said collar and to the shaft A'. The periphery of each cam is in contact with its corresponding roller 4, whereby as the shaft A rotates the link 2 will be reciprocated, so that the sliding piece F is caused to describe a horizontally-reciprocating movement at right angles to the direction of movement of the carriage B. The gumming-stamps H, I-I, and H2 also make this horizontal movement. The guides fof the sliding piece F, to which is attached an operating-rod F', are fixed to a support G, which is vertically adjustable on guide-bars g and which is connected with a rack G', this latter being pivotally connected with a verticallyoscillating lever g. The latter receives its movement by means of a roller connected thereto and traveling on a cam 5, which is fixed on the parallel shaft A.

If the gumming-stamps H H H2 convey no gum onto the blanks Z, the stamps or rather the vertically-moving support G is not lowered, and this is effected by not releasing a pawl g2, which engages in the rack G and is mounted on a bracket G2. A lever G3, Fig. 15, mounted on a projection fAl of a bracket F4, which carries the lever F2, serves for releasing the said pawl g2, and for this purpose said lever G3, which is maintained in a given position by means of a spring g4, is connected with the pawl g2 by means of a connectingrod g3, having a slotted end, through which passes a pin g5, carried by the pawl, whereby the pawl is forced to remain constantly engaged with the teeth of the rack G, so that the latter can only descend when the machine attendant places his foot on a treadle at the free end of the lever G3, thus causing the latter to be pressed down and the pawl g2 to be disengaged from the rack G, and in this condition it can descend, together with the mechanism connected with it.

The gumming-roller e ofthe gum-holder E is constantly rotated by means of the device shown in Figs. 1 and 2G, so that fresh gum is always equally distributed over the surface IOO IIO

of the roller. The stamps II H2, which rub on the gumming-roller e, are always evenly coated with gum on their stamping-faces, and on the descent of the support G the gum is conveyed onto the parts of the sheet Z which are shown shaded in Fig. 1 of the drawings, (station II.)

The continuous operation of the gummingroller e is effected by means such as shown in Fig. 26 and consisting of beltpulleys e2 e2 e4 c5 from the shaft E', which through belt-pulleys e and e7 is operated by means of a frictionpulley es, mounted on the same shaft as the pulley e7, which pulley es rests on the drivingbelt pulley E3 of the machine. The shaft of the friction-pulley es is adjustably mounted in a lever E2, and the pulley e8 may be thrown out of operation by elevating the` lever E2.

The blanks Z pass from station II over stations III and IV (where they are intermittently held down by retainer-plates d) to the station V, Where the main functions are completed.

The mechanism operating at station V is mainly shown in Figs. 9 to 14 of Sheet 3 or Figs. 33 to 36 of Sheet 6 of the accompanying drawings. In place of the table C, which ends at this stopping-place, and of the carriage B, which alsoonly travels as far as this stoppingplace, a vertically-movable folding-box J is provided, Figs. 10 to 14, which box when atl rest has its upper part level with the table C, and on this boX the blank Z is held in a proper position by contact with two vertical elbowpieces w in place of the elbow-pieces c, previously mentioned. A hollowcore or mandrei L lies over the folding-box J, which mandrel is removably fixed in a support K, fixed on the bed-plate A at one side of the machine, as will be fully understood from Figs. 30 and 31. The folding-box J is fixed on a vertical guide-bar t', which is held in a socket J4, and connected with an operating -lever J3 by means of a coupling-piece J2 and a link ft2. Said lever J3 is operated by a cam 6 on the shaft A'. An extension of the couplingpiece J2, which is guided at the end by a bar t4, prevents the folding-box from turning sidewise. The blank Z lies in the position shown in Fig. 17, Sheet 5, on the foldingboX J, directly under the folding-mandrel L. On the box J being raised the blankZ looked at from above assumes the form shown in Fig. 18. The blankZ is then folded over the upper surface of the mandrel L by the first longitudinal folder q, which is attached to the folder-carrier Q. The carrier Q, carrying the folder q, (see Figs. 11 and 12,) slides in guides on the support K and is moved over the mandrel L by means of a lever Q', which is pivotally connected at k to the support K and connected by means of the coupling-rod q' with the carrier Q. The lever Q' receives movement from a lever Q2, whichis connected with the lever Q by a link q2 and which carries at its other end a roller-bearing on a cam 7. The gummed -longitudinal side of the blank Z is nowpressed over the already folded-down side (to which it adheres) in a similar manner to that previously described by means of a second longitudinal folder .19', which is mounted on a carrier P and operated from a cam S by means of link p', elbowlever P', and rod p2. the gummed side, a plate N, Fig. 10, provided with an india-rubber face mis employed, which by means of an elbow-arm N', pivotally mounted in projection 7c' of the support K, is pressed down by means of a rod N2 from a cam 9 on the longitudinal side of the folded blank Z. In order that the elbow-lever N shall return automatically to its normal position,in which the plate is elevated, a suitable weight n2 is provided on the rod N2. The blank Z has now the form shown diagrammatically in Fig. 20, looking from abovethat is to say, the bottom parts are not yet folded down.

S S2 S3 S4 are the bottom-folding slides, (shown on a larger scale in Figs. 13 and 14,) which slides are mounted firmly on bars s to s4,which are arranged to slide on the inner side of a support O, and serve for folding around the bottom parts of the bag. The movement of the bottom-folding slides takes place one after the other in the succession I II III IV, (shown in Fig. 14,) the slides S to S4 successively rubbing on the end of the mandrel L and effecting the folding down of the bottom parts of the bag Z. Thus two diametrically opposite bottom-folders always rest on the core. The three slides S S3 S4, or rather their guidebars s' s2 S4, receive their movement from a common slide-bar O', (see Figs. 9 and 10,) mounted in projections 0 on the support O, which slide-bar O receives a reciprocating motion by means of elbow-lever R, link fr, and rod R from a cam l1. This movement is transferred in dierent ways to the operating-levers T T3 T4 of the respective bottom-folders, which are revolubly mounted on pivots o, o3, and o4. The elbow-lever T comes first into action and pushes the bottomfolder S' downward. Then folding-slide S2 is moved by means of a special cam 10 through a lever T2, which is pivotally mounted on a support a3 and is connected by means of a link t2 with the slide 32 of the bottom-folder S2. The drawing back of the lever T2 into its normal position is effected by means of a spring t3. In its normal position the lever T2 rests on the set-screw t4, Fig. 9. After bottom-folder S2 there comes into action bottomfolder S3 by means of a lever T3, pivotally mounted on a projection o3 of the support O, which lever is operated by an arm 05, fixed on the slide bar O, and` finally the bottomfolder S4 is operated by lever T4, pivgted at o4, connected to the folders S4, and provided at its upper end with a pin which projects into a slot in the slide-bar O', whereby the latter is first moved back to a certain extent before the slide S4 comes into action. A spring 06, connected at one end to the slide O' and In order to firmly press roc IIO

at the other end to the support O, serves to retract the slide O' after it has been moved byits actuating mechanism from the cam 11. The folding around of the bottom parts of the blank Z, which now forms a bag Z', is thus eiected, and there then takes place the further action of the ejection of the bag Z' from the mandrel L under the constant pressure of astamp against the bottom of the bag, which function may most clearly be seen from Figs. 10 and 13 on Sheet 3.

An ejecting-rod L is movably mounted in the hollow mandrel L, Fig. 10, and on one end of this rod is attached a small plate Z', which passes into the conical front opening of the mandrel L and forms one plane with the end face of the latter. The rod L' is connected by means of a connecting-link Z2 with the lever L2, pivotally mounted on a bracket L", which lever L2 receives motion from the ejecting-cam 14 by means of a rod L2. A rod M is arranged in guide-supports M' in a line with the rod L' on the opposite side, and said rod M is provided in front with an india-rubber-covered plate m. Before the rod L or its plate Z' commences the ejection of. the bag Z' from the mandrel L the india-rubber face of the plate m presses against the folded bottom of the bag Z'. The rod M is connected by means of a link m with a lever M2, which is pivotally mounted on a bracket M4 and operated by means of a rod M2 from a earn 12. A brake-segment m2 is fixed onto lever M2. A brake-block m2, which is pressed down by means of a spring m5, having an adjustable pin m6, bears on said brake-segment. The pin m6 of the brake-block M8 is ,adjustably mounted in one end of a lever M6, the other end of which carries a roller engaged by a brake-cam 13. The lever MG is pivotally mounted on a standard M5, which is attached to the bracket M4. The latter is supported from below by means of a support m4. So long as the ejection of the bag from the mandrel takes place the india-rubber face of the plate m rests, as already mentioned, against the bottom of the bag Z', and the cam 13 is operated in such a way that it presses the brakeblock M3 strongly against the brake-segment m2. The pressing back of the rod M by means of the rod L' forms, therefore, a yielding resistance, and the consequence of this is that the bottom of the bag Z', situated between M and L', is powerfully compressed during the ejection of the bag from the mandrel, so that the gum in the bottom parts adheres so firmly that anyau tomatic separation of the gum med bottom is avoided and a thoroughly-smooth bottom is obtained. The rods L' and M, together with the bag Z', having reached the end of the ejecting movement, the rod M, together with the plate m, remains temporarily stationary, while the ejecting-rod L' moves so far back again that its conical plate Z' rests in the corresponding recess in the hollow mandrel L.

In order that on the return of the ejectingbar L' the bag shall not return with the same, the device shown in Figs. 9, 12, and 25 is employed. This consists of a plate U2, on which two elbow-pieces U are adjustably mounted. On one of these elbow-pieces U, as shown in Figs. 25 and 12, thereis attaehedin addition a retaining-arm u. The plate U2, together with the elbow-pieces U and arm u, is operated from the cam 15 (see Fig. 9) by means of an arm u', mounted on the lever U' in such a way that the plate U2, together with the elbow-piece U and the retaining-arm u,'is before the returning movement of the ejecting-bar L' pushed so far against the bag Z" that the arm u rests in front of the endofthe bag and prevents its return movement. Before, however, the plate Z of the rod L reaches the edge of the bag the plate U2, together with the arm u, returns so far back that the plate Z' can pass by. A second and more powerful pushing of the plate U2 against the bag Z', which lies loosely on the block V, then takes place, the elbow-piece U throwing the finished bag Z' over the sloping-shaped block V, from whence it slides into a collecting-receptacle. The lever U' is retained in a suitable position by means of a spring u2, and by mea-ns of this spring its roller u' is pressed against the cam 15 and operated by the latter.

On each reciprocating movement of the carriage B a fresh sheet is always laid on the first station and a finished bag, with a bottom completed, is ejected. The cams 1 to 15 are so arranged that the actions of the various devices, more particularly those of station V, follow in succession at the right time.

Sheet 5 of the drawings, Figs. 17 to 25, shows the gradual formation of the paper blank Z into a bag with a bottom. Fig. 17 sltows the blank Z lying under the mandrel L. In Fig. 1S the folding-box J has pressed the sheet over the mandrel L. In Fig. 19 the first sidefolder q has completed one longitudinal fold. In Fig. 2O the second side-folder p has completed the second longitudinal fold. Figs. 2l to 24 show the formation of the bottom after the bottom-folders S' to S4 have successively operated. Fig. 25 shows the removal of the finished bag from the mandrel and theejection of the same.

According to the sectional form of the mandrel L (which may be of a round, oval, rectangular, polygonal, or other form, as desired) the forms of the longitudinal folders q and p must be arranged. A modification of the bottom-folders must be made corresponding to the sizes of the bag by changing the respective folders S' to S4.

A device for folding broad bags is shown in Sheet 6 of the drawings. Attention in this case is directed to the fact that the blank which is pushed over the folding-box J ou passing the recess t' of the folding-box would descend in front and encounter with its front edge one side of the recess t' and would bend or could not be brought into the correct position. In order to avoid this, a bridge-piece IOO IIO

X is arranged in the recess c' of the foldingbox J, lying at the top and level with the upper surface of the folding-box. This bridgepiece is vertically movable, which movement is produced by mounting it on a bar Which' slides in a socket on the folding-box J. A spring x3, which is iixed at one end to the socket of the folding-box and at the other end to the lower stop-ring 002 on the guidebar or, holds the bridge always in the abovementioned position, while aniupper stoppingring x4 bears` against the socket 0c. If the folding-box J be pushed against the mandrel L, the bridge X yields with a spring action and lies then in a suitable depression in the recess i of the folding-box. On the descent of the folding-box the bridge X presses the sheet of paper Z from below against the mandrel L until the bridge again lies level with the upper surface of the folding-box. The folding of the bottom parts in the case of wider bags is also performed in another manner to that hereinbefore described. The succession in which the bottom-folders S to S4 come into action is also different. In this case the horizontal folders S3 and S4 first come into action and then the upper folder S and finally the lower folder S2. The corresponding succession in the action of the folders is indicated by I to IV in Fig. 28. The device for operating the bottom-folders is of course suitably moditied. The bottom-folders S3 and S4 are again operated from a common slide O by means of levers T3 and T4, and the lower slide S2 is also set in action as before by the lever T2. On the other hand, the operation of the bottom-folder S', which is here the third bottom folder which comes into play, is effected in a different manner from that previously described by means of an elbow-lever T5, Fig. 26, which is operated by means of a slide-bar i5. This slide-bar t5 is beveled at the top, and one arm o5 of the lever T5 is drawn, by means of the spring t7, against the bar t5 in such a way that the roller r4 always rests on the edge of the bar t5. The latter is arranged so as to slide in a socket or bearing o7 of the support O and is operated from the extended lever T2 by means of a link t6. On the raising of the slide-bar t5 the lever T5 is turned, the roller r being forced outward by the upper inclined edge of the bar. As soon as the roller r' has passed the inclined part of the bar t5 and engages the vertical part a further movement of the lever T5 can no longer take place, even if the slide-bar t5 be moved farther, since there is no tendency of the bar t5 to force the shoe outward. The return movement of the lever T5 takes place by means of the spring t? after the bar t5 has been lowered.
