ABSTRACT:
A machine for the manufacture of an axially prestressed coil out of a strip of material for covering various types of machine components, such as spindles, shafts and columns. The coil is to have an elongated and spiral-like form. The machine which is capable of manufacturing this product includes a feed roller pair for feeding the strip by the use of an associated feed drive mechanism. The feed rollers are movable against one another through a clamping device. A bending roller is arranged at the exit from the feed rollers. A support structure is provided for the bending roller to facilitate a movement thereof to effect not only a cylindrical bending of the strip material but also, and upon a swivelling of the bending roller, a cylindrical as well as an increasing diameter spiral can be formed.
