SU1574378A1 - Guiding arrangement for feeding continuous material - Google Patents

Abstract

The invention relates to the field of mechanical engineering and can be used to feed a long material with a constant cross section profile. The aim of the invention is to increase durability and speed. When the body is fed under pressure into the cavity 8 through the opening 13, the corrugations of the bellows 3, covering the elastic element 16, are compressed in the radial direction, deforming it before clamping the material 18. The deformation of the bellows in the radial direction in the rest of the area is prevented by washers 17 deformations. Under pressure, the piston 6 moves when there is no pressure in the cavity 7. The bellows 3 is then extended, and the bellows 2 is compressed in the axial direction. There is a supply of material in one step, equal to the course of the piston. 7 il.
