Description

They provide high quality joint of edges 4 and 5, as well as high frequency of the surface of the tool roll, which excludes the possibility of damage to the coil material. In order to increase the fastening strength, the screws 9 and the pins 10 are arranged in a staggered order in two rows.

In order to ensure the failure of the cutting elements, the wedge 7 must be (see FIG. 3) brought along the inclined bottom of the caiaca 8 all the way into the sheet metal. This is accomplished with the longitudinal movement of the wedge due to the pins 11 and the grooves 12 that are co-located in the body, with which the wedge is placed on the pins 11. With the emphasis placed on the leaf spring, the wedge and the wall of the groove 8 should be equal along the entire length of the gap. This is accomplished by the accuracy of the dimensions of the wedge and spring manhole. In addition, the (Pre-fastening of the leaf spring determines the desired position of the wedge into two grooves 8, ensuring the contacting of the wedge with the leaf spring along the entire length is mandatory. The coordinates of the holes for the pins 11 are determined through the grooves 12 of the wedge located in specified method position.

A manual paper cutter shown in FIG. 1 is an example implementation of the invention. Rolls 1 and 3 are mounted in sliding bearings 13 to 14 on vertical stands of the bed. The ends of the rolls from the side of the arm extend beyond the end of the stand 15 and gears 16 and 17 are fixed on them to synchronize the rotation of the rolls, and also the handle 18 to rotate the tool roll. A roll of paper 19 with bearings at the ends of the centering axis is mounted on the prisms 20. The paper tape, unwound from a roll, is tucked into the gap between the rollers. Further, the rolls are pressed towards each other by rotating the nuts 21 at the ends of the bolts 22. The rolls are pressed against this by the eccentricity of the mounting holes in the bearings 13 and by the rotation of these bearings by the brackets 23.

The dimensional cutting process is carried out as follows. With a tool roll diameter of 63 mm, the roll circumference is 200 mm. For pieces of a sheet 1200 mm long, it is necessary to make a handle 18 six turns, three of this before completion

the sixth turn you need to move the copier 25 by the handle 24 after the cutting edges 4 and 5 leave the cutting area, the copier 25 returns to the initial position by the handle 24, so that the wedge 7 before the next

the entrance of the cutting edges to the cutting zone returns to its original position, supporting the leaf spring and preventing the cutter device from operating (up to the twelfth rotation of the tool roll). Further

operations are repeated. The required number of revolutions is measured visually. The cut sheets of paper are retracted from the rolls with the virgin hand and after the pieces are stacked, placed in the immediate

proximity to the machine.

If there are several knife devices on the tool roll, the visibility of the reference of the required number of passages of the knife devices through the cutting zone can be

made easier by installing a special counter above the instrumental.
