For basing the feed material 14, the device 2 is equipped with rulers 15, rigidly connected with the supports 6 and located perpendicular to them. The stop 4 is made in the form of rods 16 located parallel to the supports 6, heads 17 mounted with the possibility of adjusting movement along the rods 16 to set the length of the cut sheet 3 and fixed on the rods with latches 18, guides 19, placed at both ends of the supports 6, and rods 16 parallel to the shaft 12, bushings 20, 21 mounted on the guide 19 with the possibility of longitudinal displacement and ........ sharnirnosoedinennyh with the rods 16, ^Λ al crossmembers 8 - by means of hinges 22. The sleeves 20 are connected to the hollow cylinder ndrami 10 by means of leads 23 fixed to one end of the hollow cylinder 10.

The adjustment unit 5 is made in the form of rods rigidly fixed to the 'guides 19, the gears 24 interacting with the racks and connected with the bushings 20 21 and with the drive 2 5'. The drive 25 may be manual in the form of a handwheel. The movement of the heads 17 of the stops can also be either mechanical or manual '. The receiving device is installed from back 10. . . . .. 55 ’’ neustrons of scissors 26, for example guillotine ones ”with fixed lower and movable upper knives.

........ 7 The receiving device does not work as it should.

Rotating the flywheels 25, they move to the width of the sheet 3 along the guides 19 of the sleeve 20 and 21 with the supports 6 and stops 4 mounted on them. Then, moving the heads 17 of the stops 17 on the rods 16, the required length of the cut-off sheet 3 is set4 and the heads are locked with clamps 18. The machined sheet 14.

served in scissors 26 to the stop in the head 17 and cut off the workpiece. At the end of the knife stroke, the system is triggered. control (not shown), including the power drive 13, which by means of the shaft 12, levers 10 and brackets 9 rotates the supports 6, leading them out from under the cut sheet 3. Sheet 3 falls down and is stored in a stack. The receiving device can work with one emphasis, basing the cut sheet 3 along the lines 15.

The use of an individual drive ensures the formation of an even foot and the possibility of storing short sheets in a bundle without the scissors knives running.

The presence of two stops allows you to accurately set the length of the cut sheet, regardless of its width.

the design of the receiving device expands its technological capabilities, providing cutting of both narrow and wide sheets and their basing.
