The invention relates to the processing of materials by cutting and can be used for cross-cutting continuously moving material, such as a strip of polymeric material.

The purpose of the invention is to increase the accuracy of the cut blanks.

FIG. 1 shows a device for transverse cutting of long material, general view; in fig. 2 is a view A of FIG. one.

The device consists of a frame 1 on which the drum 2 in the bearings is rotatably mounted, on the shaft of which a carriage 3 is mounted, having the possibility of reciprocating rotational movement and made in the form of two pairs of radially mounted and interconnected struts. In the planes perpendicular to the end surface of the drum 2, the axes 4 of the clamps 5 with rotating rollers 6, which contact the copier 7 fixed on the bracket 8, are mounted. On the carriage 3 there is a platform 9 for engagement with the axles 4, and for the resetting of the axis 4 is provided with springs 10. On the C-shaped crossbars 1 of the carriage 3, the knives 12 are fixedly fixed, and the U-shaped crossbars 11 are in the guide bushings 13 of the carriage 3 and are able to reciprocate as a result of interactions Twi roller 14, the axis of which is fixed in a U-shaped cross member 11, with cam 15 rigidly attached to the bracket 8. The U-shaped cross member 11 are provided with nuts 16, regulating the working ho blades 12 by a spring 17, and I

the spring 18 ensures the return of the carriage 3 to its original position. The clamping mechanisms 19 mounted on the drum 2 have clamping plates 20 and each is made in the form of a two-arm lever 21, one of the arms of which is a V-shaped profile, and a contact roller 22 interacting with the cam 23 fixed on the bracket 8 is fixed on the second shoulder and the damping spring 24 has the ability to move the bar 20 to its original position. On the frame 1 is fixed puller 25.

The device works as follows.

The strip material 26 is guided to the outer surface of the rotating drum 2, the roller 22 slides on the copier 23, and the presser bar 20 of the double-arm lever 21 presses the material 26 to the flange of the drum 2. Next, the axis 4 of the retainer 5 moves as the result of the movement of the roller 6 along the copier 7 , engages with the platform 9 of the carriage 3, which begins to move synchronously with the drum 2. When the carriage 3 moves, the roller 14 U-shape of the cross member 11 interacts with the cam 15 and the material 26 is cut with the T2 blades, upon further movement the roller 14 comes out with the cam 15, and the U-shaped cross member 11 together with the blades 12 returns to the non-operating position under the action of the spring 17, while the axis 4 of the retainer 5 slides off from the platform 9 under the action of the spring 10, and the carriage 3 reverts to the initial position . Next, the contact roller 22 comes off the copier 23, and the double-arm lever 21 under

the action of the spring 24 expands the cut strip material 26, and the puller 25 removes it from the surface of the drum 2 and sends it for further transportation.
