摘要:
A process and an apparatus for the peeling of wire wound into a coil and/or to be wound into a coil in a wire peeling machine. The wire is peeled bent in the form of a loop, with the individual wire loops having a curvature corresponding essentially to the curvature of the wire in the coil and the wire loops being separated so that the wire is being guided on a helically curving path. At least in one location a piece of a wire loop is spaced apart from two adjacent pieces of the adjacent loops so that a peeling head peeling a first loop piece may be accommodated between the two other loop pieces. In particular, the wire is guided helically on the circumferential surface of a partial annular torus or a cylinder. The wire may be peeled directly, i.e., without prior straightening. The axis of rotation of the peeling head is perpendicular to the plane formed by the curved axis of the coil, which also contains the axes of the disk or disks. The axis of rotation of the peeling head is horizontal. The peeling plane is located vertically above the axis of the coil.

A pipe-welding mill for production of coiled pipes from coiled strips comprises a coil preparation section including unwinders disposed in a manner allowing displacement thereof in a direction perpendicular to the direction of pipe movement, and a magazine including a reel with set-up coils, the mill further including a strip coupler, shaping, welding, and drawing stands, a coiling arrangement with bending rollers, and cutting and receiving arrangements, the components being successively installed in the direction of pipe movement. Guide or receiving rollers of the receiving arrangement are located on a platform installed in a manner allowing the platform tilt with respect to the axes of the bending rollers, the receiving rollers being connected to the output shaft of the drive of the bending rollers through a universal joint.
