DEVICE FOR SUPPORTING OF SHEET MATERIAL IN CUTTING Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: device has supporting member in the form of bracket 2 coupled to rear rest 1. Bracket 2 carries moving member made as turning lever 4 with counterweight 6 fixed at right angle to axle 10 at one end and catcher 7, at the other. Turning lever 4 moves under the action of sheet material 5 towards rest 1 and is capable of returning to initial position. Supporting member 8 is mounted on axle 9 of catcher 7 for contact with sheet material 5. Bracket 2 is provided with longitudinal recess 11. Turning lever 4 has recess 12, and it is hinge-connected for movement along recess 11 of bracket 2. Catcher 7 is mounted for axial movement in recess 12 of turning lever 4. Supporting member 8 may be fitted with controllable electromagnet. EFFECT: more effective feed of sheet material. 3 cl, 1 dwg
