FRIEDRICH ALTMANN, OF BRESLAU, GERMANY.-

MACHINE FOR MAKING PAPER-LINED PASTEIBOARD BOXES.

' Specification of Letters Patent.

Patented Dec. 2, 1913.

Application filed October 23, 1912. Serial No. 727,471.

To all whom it may concern:

Be it known that I, FRIEDRICH ALTMANN, a subject of the German Emperor, and resident of Breslau, Germany, have invented certain new and useful Improvements in Machines for Making Paper-Lined Pasteboard Boxes, of which the following is a specification.

Hitherto, a machine for making paperlined paste-board boxes has become known, in which previously cut lengths of pasteboard are singly ejected from a container by a hand-operated slide onto a somewhat wider, stepwise movable paper ribbon, which is on its upper surface provided with glue, and are then brought to below a press and combined therein with the paper ribbon carrying them, which at the same time is cut off by a knife, whereupon the projecting paper edge of the work-piece, which is intended for lining the upper box edge, is turned over by a hand-operated tiltingledge, whereas all other work, namely the transformation of the work-piece to a frame, the insertion of the bottom and the bending and pressing-on of the other paper edge, which is necessary for fixing the latter, must be effected by hand. Certainly, it is not novel to perform the transformation and further formation of the paste-board pieces, which are prepared on the known machine and connected with the paper webs, on a ma chine, in which the web, of which one paper edge must already have been turned over, is

brought between a winding bolt and a guiding roller located directly above the latter and from which the web is led around the bolt, while at the same time a folding roller, which is connected with the guiding roller, places the projecting paper web edge over the edge of the box bottom, which has already been previously pressed upon the face of the winding bolt. In this machine, however, for turning over the web around the winding bolt, besides the guiding roller a further winding cord, which is led over the latter and the bolt, is necessary, and each finished box must be removed from the bolt by hand. Besides, the two known machines cannot be so combinedthat the manufacture of the box would be possible in a continuous, uninterrupted way.

The resent invention provides a machine, by .WlllCll paper-lined paste-board boxes of previously cut lengths of paste-board can be automatically made in a continuous, uninterrupted way and the finished boxes also be automatically ejected.

According to the invention, the paper ribbon and the front, non-supported end of the paste-board length, which is located at a certain distance above the paper ribbon and periodically supplied, are caught by a pair of known periodically disengageable conveying rollers and are glued together during their advance, while the projecting edge of the paper web, which has meanwhile been cut off from. the ribbon, is first bent by an inclined ledge, whereupon the whole workpiece, while advancing, passes beneath a winding bolt, which is narrower than the paste-board length, where it is caught by a rotary clamping member and led around the bolt, while at the same time also the other projecting paper edge, which serves for fixing the bottom of the box is turned over by known folding rollers upon the bottom, which has previously been pressed upon the face of the winding bolt. Furthermore, in the extension of the winding bolt a piston and a shell inclosing same are movably located on a common axle and adapted to be moved successively toward the winding bolt and back by means of a pair of camoperated levers, so that the piston places the paper edge, which has first been bent by the ledge, around the inner box edge, while at the same time a vertically movable molding-roller, which is located beneath the winding bolt, smoothens the outer box envelop and the shell, which is movable on the piston, ejects by its now following forward movement the finished box from the winding bolt.

Periodically disengageable conveying rollers for conveying work-pieces are, of course, not new per 86 but according to the invention they do not only serve for advancing a work-piece but, further, for combining the two parts of the work-piece and at the same time for assisting in the further formation or transformation of one part, that is they are used for a purpose hitherto not known in the art.

The accompanying drawing shows the improved machine.

Figure 1 is a plan view of the same, Fig. 2 a front view omitting the container for the paste-board pieces, Fig. 3 a side view of part of same, Fig. 4 a fragmentary sectional side view on the line BB of Fig. 1, Fig. 5 a plan View, partly in section, of the container for the paste-board pieces with cutting-off device and clamping means for the paper web, Fig. 6 a front view of the latter arrangement, and Figs. 7 and 8 sections on the lines CG and DD of Fig. 6 respectively.

The paper web 1 (Fig. 4) arrives from a paper roll and is led over a roller 2, which rotates in glue, its free end being before commencement of the operation introduced by hand into the race 3 of the machine. Beside the latter, a container 5 (Figs; 5 and 6) is fixed and filled with superposed paste-board pieces 4, a slot being provided on each longitudinal side of same directly above its bottom, so that by means of a slide 11, which is connected with levers 6, 7, 8 (Fig. l) and controlled by a cam disk 10 on an axle 9 one paste-board piece can be ejected from the container 5 upon each stroke of the slide until it abuts against a lateral boundary abutment-ledge 12 of the race 3. Thereby, the paste-board piece is put upon a number of horizontal tongues 13 attached to the bottom of the container and provided with clamp-springs 13 and which serve to keep the same apart from the somewhat wider paper web. In this position, the non-supported projecting end of the ejecting paste-board piece is disposed beneath a roller 14, which is located on an angle-lever 15 (Figs. 1 and 4) which is loaded by a weight 15 and controlled by a cam disk 16 on the axle 9, so that it can be alternately lowered and again be raised by action of said lever. The end of the paper web in the race 3 is carried by cross-ledges 17 (Fig. 5) and supported in the vertical plane of roller 14 by a roller 19, which can be driven from a toothed gearing 18 Upon the roller 14 being lowered by action of the cam disk 16, it presses that part of the paste-board piece, with which it comes in contact, upon that part of the paper web, which rests upon the roller 19, whereby, owing to the paper web being provided with glue on its upper surface, the contact points are glued together, while the toothed gearing 18" is put in gear, so that the two connect'ed pieces are advanced and thereby glued together on their whole length. Meanwhile, the cam disk 16, during its further rotation, turns the lever 15 in such a way that the roller 14 is again lifted by the same, whereby the movement of the paper ribbon is stopped. At this moment, a knife 24, which swings on spring bolt 23 and which is acted upon by levers 21, 22 which are controlled from a cam disk 20, is operated in such a way known in the art that it cuts the paper web off, somewhat behind the paste-board piece connected therewith. In order to prevent, during this action, a back ward displacement of the free end of the paper ribbon, which lies then loosely in the race 3, the operating lever 22 of the knife is connected with a double-armed lever 26, which is fulcrumed 25 and the front arm of which presses with its angularly bent horizontal end 26 on the free end of the paper ribbon at the moment of the cutting operation and thus prevents the same from slipping back. Upon the two parts of the work-piece being connected and moved forward, one projecting edge of the paper web, which serves for lining the upper box edge, strikes against a lateral ledge 27 5) in the race, which bends the same angularly. Thus prepared, the workpiece passes beneath a winding bolt 28, on the face wall of which a box bottom, which is taken from the container 29, has meanwhile been placed and secured in a way known in the art. At this moment, the front end of the workpiece is caught by a clamping member 30 (Fig. 2), which rotates with the winding bolt 28 and which is periodically disengageable, and wound around the bolt, while the other projecting edge of the paper web, which serves for fixing the bottom, is placed upon thebottom edge by folding rollers 31 (Fig. 4) known in the art.

The clamping member 30 receives its movement from a double-armed lever 32 connected therewith and fulcrumed on the end of a member 35, which is fixed on a toothed wheel 33 and movable on the axle 34 and provided with an angular arm 35*. The front arm of the double-armed lever 32 is connected with the arm 35 by a tensioned spiral spring 36, while the end of its rear arm is disposed in the vertical plane of a ring segment 37. The toothed wheel 33, is connected with the member 38, which is moved to and fro by action of a lever which is controlled by a cam disk 39, where by the member 35 on the double-armed lever 32 is alternately moved in opposite directions on the axle 34. By the tendency of the tensioned spring 36 to approach the front arm of the double-armed lever 32 to the arm 35, the clamping member 30 is pressed against the winding bolt 28, where by it catches the front end of the advancing work-piece. As the lever 32 is then turned on the axle 34, the clamping member 30 re mains on its pressure place and rotates with the winding-bolt, it placing the work-piece, which is guided on the ledge 17 around the bolt. At the same time, the rear end of the double-armed lever 32 moves around, the ring segment 37 until it slides down from the same and finds its abutment on a gripper-like finger 41 connected with the segment axle 38 (Fig. 3). At this moment, the segment 38 passes into its backward movement and causes thereby also the movement of the double-armed lever 32 in opposite direction the rear arm of same being by the finger 41 pressed below the segment ring, on the lower surface'of which it moves then back, so that the clamping member 30 is raised from the winding bolt, until the lever arm, at the end of its backward movement passes from below the other end of the segment ring and by action of spring 36 outward so that the clamping member 30 can catch the next work-piece and place the same around the bolt at the following forward movement of the lever 32. Upon the work-piece being-wound on the windingbolt and the bottom glued thereto by the folding rollers 31 (Fig. 4), a piston 43, which is located beside the winding bolt 28 and movable on the axle 42 of same, is moved toward the bolt by action of a doublearmed lever 45 which is controlled by a cam disk 44, the piston pressing then the previously bent paper edge onto the inner edge of the box, while at the same time a vertically movable pressure-roller 46, which is located below the winding roller and shaped corresponding to the form of the box, and which may also be fitted with printing types for printing on the name of the firm or the like, smoothens the box envelop. This process being finished, immediately after lowering of the roller 46 a shell 47 inclosing the piston 43 moves toward the bolt by action of a double-armed lever 49, which is controlled by a cam disk 48, and ejects the finished box.

The putting of the box bottom on the face of the winding bolt is effected in a way known in the art during the time, in which the roller 14 combines the parts of the work-piece and moves same toward the winding roll, the bottoms being stored in a container 29 beside and above the winding bolt, from which they are periodically ejected by levers, which are controlled by a cam disk, the bottoms being then led to a pair of tongs 50, which bring same by action of an eccentric into vertical position and place them on the face of the winding bolt, where they are held by the head 34" of the movable axle 34, which is controlled by cam disk 52, until the projecting paper web of the work-piece has been placed around the edge of the bottom by action of the folding rollers 31.

I claim:

1. In an automatic machine for making paper-lined paste-board boxes, the combination of a pair of periodically disengageable conveying rollers designed to catch the paper lining and the front end of a pasteboard piece and to press them together on their forward movement, an inclined ledge to first bend the projecting edge of the paper web which is to line the upper box edge, a winding bolt of narrower width than the paste-board piece, a clamping member to lead the workpiece around the winding bolt, folding-rollers to turn the other proj ecting edge of the paper web upon the bottom of the box which has been pressed upon the face of the winding -roll, a movable piston and a shell inclosing same arranged in the extension of the winding bolt, a common axle for the piston and shell, levers to move the latter alternately toward the wind ing bolt and back and to allow the piston to place the previously bent projecting edge of the paper web around the inner box edge, and a vertically movable molding roller beneath the winding bolt to smoothen the outer box envelop, all for the purpose set forth.

2. In an automatic machine for making paper-lined paste-board boxes, in combination a winding bolt, a clamping member to wind the work-piece on the same, a doublearmed lever to carry said clamping member, a toothed wheel on the fulcrum of the lever adapted to be moved alternately to and fro, and a tensioned spring as well as a ring segment to control said lever and to cause same to alternately press the clamping member upon the bolt, in order to rotate with the same, or to lift it away therefrom to start for the engagement of the next workpiece.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
