Concrete reinforcement or sheathing support - cutting tools with U-shaped cutting edges arranged in pairs to centre line

摘要

Reinforcing sheet has two shanks angled near an upper belt where, by slotting, struts formed by sheet strips are drawn out or bent out to meshes. a sheet strip is stepped by a mesh length. A device forms the top belt, and spaced and displaced to each other a set of cutting tools with V-shaped cutting edges arranged in pairs are raised and lowered so taht the first pair of cutting tools is farthest from and the last pair closest to the centre line. The cutting tools are inwardly displaced according to the width of the struts forming the meshes and the spacing of the tool points corresponds to 1 1/2, 2 1/2, etc. the mesh length. The cutting tool pair also has a device for after-pressing the struts, a debarring device (5), a device for bending the bottom meshes and a cut-off device (7).
