Abstract: A laying head tripper has a ramp with a lip detachably secured to its forward edge. The ramp and/or the lip are contoured to match the curvature of the rings being formed by the laying head.
Abstract: A method and apparatus is disclosed for temporarily interrupting the passage of a long product between upstream and downstream paths in a rolling mill. Product passing along the upstream path is delivered onto a cylindrical drum. The drum is rotated in one direction to accumulate the product thereon in a series of windings. The direction of drum rotation is then reversed to unwind and deliver the accumulated product to the downstream path.
Abstract: A laying reel for coiling wire has a generally spiral laying tube generally centered on and rotatable about an axis and having offset from the axis a tangentially directed output end. The wire to be coiled extends through the tube and exits the output end thereof. A brake shoe at the output end is engageable with the wire extending therefrom. An actuator urges the brake shoe against the wire and thereby brakes the wire as it exits the output end.
Abstract: Coil-forming head to form coils starting from continuous and substantially rectilinear rolled stock, of the type comprising a mandrel rotating around a substantially horizontal axis, containing inside itself a shaped tube conformed as a spiral inside which the rolled stock is introduced, there being included, in cooperation with the outlet end section of said shaped tube, a ring-shaped containing element arranged outside said shaped tube and including at least a segment of inner wall which tapers and diverges towards the outside suitable to allow a controlled expansion of the trailing-end segment of the rolled stock.
