The invention relates to the cold working of metals by pressure and can be used to transfer lengthy material.

The aim of the invention is to expand the technological possibilities by forming protrusions displaced relative to each other on the sheets in order to prevent the sheets from sticking together when they are stacked on top of one another.

Fig. 1 shows a device for moving sheet material; 2 is a view A of FIG. 1.

The device contains hollow feed rolls 1 and 2, covered with elastic friction material 3, grooves 4 and 5 spring-forming shaping rods 6, on the ends of which the mapping signs 7 are made, toothed lugs 8, axes 9 with prisms 10, guides 11 mounted on the base 12, the adjusting screws 13, the springs 14, the cams 15, the gear rims 16, the screws 17, the nuts 18, the gears 19, the position 20 designates the sheet material. On the base 12 there are slots 21 and 22 in which the prisms 10 move, the springs 14 are located between prisms 0, Axis 9 are integral with with prisms 10, axles 9 with cams 17 and nuts 18 secured cams 15, fitted with gear rims 16. Rods 6 are spring-loaded to cams 15 by springs 23. Cams 15, gears 16 and rods 6 with springs 23 are located in cavities of feed rolls 1 and 2, and the feed rolls 1 and 2 are mounted on axles 9, the toothed protrusions 8 are threaded to the rods x 6 with the possibility of interaction with the toothed rims 16.

The number of gear rims 16 rods 6 installed in the feed roll 2, less than the number of gear projections In the rods 6 installed in the feed roll 1, one.

The device works as follows.

The rotation of the feed rolls 1 and 2 is carried out through gears 19 from a gearbox (not shown).

During the rotation of the rolls 1 and 2, the rods 6 under the action of the cams 15 move along the grooves 4 and 5 and with their ends (marks 7) interact with the material 20 and form protrusions in it. At the same time, the toothed protrusions 8, interacting with the toothed rims 16, rotate the rods 6, which eliminates the coincidence of the protrusions when applying material when cutting it into sheets or laying sheets into a foot.

Claims (1)

Invention Formula A device for moving the strip and tape material comprising hollow feed rolls mounted on an axle base mounted on axes, cams mounted on axes and located in the cavities of the feed rolls, and spring-loaded shaping rods mounted in feed rolls with the possibility of movement in the radial direction and interacting with the cams, which is so tachodied by the fact that, in order to expand technological capabilities by forming protrusions offset from each other on the sheets, aversive sticking it is equipped with gear rims associated with the cams, spring-loaded shaping rods are installed They have jagged ledges with the possibility of interaction with the toothed rims.
