PATENT OFFICE

CLASS 55: Paper manufacture.

α is the paper to be cut. It is located on a roller ν, which by means of the pulley c and the driver d is brought into rotating motion between the tips 1 and 2, i is a slide on which the carriage k is located; A support p , which carries two steel points 3 and 4, is attached to this slide. Between these two tips is the support 0, which can rotate around the centers of these tips.

The support 0 carries the upright, 1.08 m long knife u, which cuts on the longitudinal edge and which is clamped to the support 0 by the plate r by means of the double bar s. The double bar ί is pushed back and forth by the lever / to either hold the knife in place or to release it again.

Simultaneously with this movement, the lever / also has the purpose of rotating the ratchet wheel χ by one tooth by means of the latch w , whereby the gear wheel y rotates at the same time. This engages in the rack z, which has the same length as the knife and is connected to it at its two outer ends.

The screw / turns by means of the handwheel g in the two bearings e; it is connected to the slide k through the nut h and is used to move it sideways.

The latch /, which can rotate on a pin between the screw nut h and the plate A, serves to regulate this movement. After each cut, the same is lifted out of the serration -in screwed onto the slideway i , in order to collapse again when the slide k has advanced by one division.

At the same time, a support B is screwed onto the slide k , for the double purpose:

1. to give the knife u more support on one side;

2. To carry a tooth segment C , in which a toothed piston D engages, the spindle of which is stored in the support 0 , and which can be turned with the crank E in order to press the knife against the paper.

In Fig. 1 to 3, sheet I, the machine and in Fig. 4 to 6 the support ο is drawn. From Fig. 1 to 4, sheet II, the devices can be seen by which the knife is pressed against the paper and by which the same can be adjusted in its longitudinal direction. In Fig. 5, the cross section of the support ο is shown with the plate r and the knife ti at the level of the center of the paper roll.

The machine works in the following way:

At the beginning of the cutting of a whole roll of paper, the slide k with the knife u is on the right-hand side at the steel point 2. The paper is now set in a rotating motion, the knife u is pressed into the paper by means of the crank E and thus causes the first cut.

Now you move the knife back again and press the lever t downwards, whereby the double bolt s moves upwards, the knife u. gets rid of and the trap w in a new tooth

of the ratchet wheel χ falls. During the upward movement of the lever t consequently the ratchet wheel is rotated around a tooth and thus the rack BEZW. the knife, which was in the highest position, pushed downwards by ι cm. This offers the second cut a new sharpness.

One now lifts the trap / it out of the tooth division m by pressing it with the finger, pushes the spindle / slide k forward until the trap hits the next tooth of the division. In this way everything is ready for the second cut.
