Patented in the German Empire on June 23, 1905.

In the previously known devices for the production of stapled with wire Tubes made of cardboard etc. must first be pre-bent with the hands, from these into the Stapling saddle inserted and after stapling in the opposite to insertion Direction can be brought out of it, whereby the work process with each tube to be stapled ίο a considerable interruption suffers.

The new machine allows uninterrupted work by moving the material Shaped by the machine into a tube, automatically inserted into the saddle for stapling and is conveyed out of it in the direction of insertion.

In drawings represent:

Fig. Ι a front view of the machine,
Fig. 2 is a plan view of the machine,

Fig. 3 is a side view of the same,

FIG. 4 shows a section according to AB of FIG. 2, FIG. 5 shows a plan view of FIG.

6 shows a section according to CD of FIGS. 5 and

Fig. 7 is a cross-section of the tube with a view of the dome and the closed one Peel.

The machine is driven by the pulley α , which is attached to the shaft d together with the cam disk b and the gear wheel c. The toothed ring cam e is driven by the gear wheel c and. through this the levers / and g are set in motion.

The movement of the lever / is transmitted by means of the tie rod h and the cranks j and k attached to the shaft i to the crank I and the shaft m connected to it, the one with the curves η and 0 attached to it perpendicular to the one in the table ρ movable box q is rotatably mounted. The rollers r and s of the slides u and t engage in the curves η and 0, which are moved up and down in the vertical direction by the curves mentioned in the box q and thereby alternately close and open the shells χ and y by means of the rollers ν and w .

The box q is provided on its upper surface, which serves as a support for the material, with a frame which determines the position of the latter and rests with the curves η and 0 on rollers 1 and 2 attached to the table below the same.

The points of the curves η and 0 which come into contact with the rollers 1 and 2 are shaped so that the box, q makes an upward movement during the closing of the trays χ and y which effect the shaping of the material, and thereby the material in order to avoid it Shift against the mandrel 3 presses. However, this pressing stops again after the shells are closed, so that the material can easily be removed from the shells through the slide 4

out and into the sleeve 5, which together with the mandrel 3 is the so-called stitching saddle forms, can be pushed.

The slide 4, which is guided by the rail 6, receives its movement from the lever 7 mounted on the table, which in turn is driven by means of the pull rod 8 and the lever g through the cam disk e .

The sleeve 5 has without an opening 9, which is the stapling point for the wire stitching head 10 the machine releases, and is also laterally provided with slots through which the The pawls Ii of the feed body 12 come to rest with their front ends according to the action of the springs 13 to apply to the mandrel 3.

The feed body 12 ■ is moved back and forth several times from the cam disk b by the intermediate members 14, 15 and 16 during a reciprocating movement of the slide 4, each time by as much as the distance between the staples to be driven into the material requires .

The wire stitching head is driven in

the known way from the disk b .

. If, for example, a suitably cut piece of cardboard is placed in the frame \ of the box q , it is pressed against the mandrel 3 by the latter, bent around the mandrel by the shells χ and y and out of the former through the slide 4 and into the Sleeve 5 pushed in.

As a result, some of the pawls are initially pushed away by the cardboard advancing and slides on this without having any effect, while the pair that was first pushed away shifts as it retreats of the slide 4 behind the cardboard again rests on the mandrel 3 to the cardboard during the forward movement of the feed body 12 by a movement corresponding to the same Push forward piece, whereupon the cardboard is stapled by the wire stitching head 10.

The feed body moves back again during stapling and the second A pair of pawls is inserted behind the cardboard in order to push it forward a corresponding piece for the purpose of stapling. This The process is repeated as often as the number of times to be driven into the tube Requires brackets.

As soon as the cardboard enters the. Sleeve 5, the shells χ and y open to release the system formed by frame % and box q for further material to be inserted; then the shells close again and thereby form the newly inserted material into a tube, which in turn is conveyed through the slide 4 into the sleeve .5. The finished tubes are then transported out of the stitching saddle by the subsequent tubes. In this way there is an uninterrupted 6g of work.

Claims (1)

Patent claim: Machine for the production of pipes stapled with wire from cardboard, leather or similar material, characterized in that to achieve an uninterrupted working process, the cut material of two movable shells, ^ and y) around a mandrel (3) is formed into a tube and a Slider (4) conveys the tube shaped in this way over the mandrel (3) into a sleeve (5) and under a stitching head, whereupon pawls (11) advance the sleeve in certain paragraphs for the purpose of stitching, which is then transported out of the machine after stitching has been completed . For this purpose 2 sheets of drawings.
