Patent DE-2012125-A1 (DE)
Title: Roll forming of cylindrical tubing
IPC: B21D22/16
Filed: 1970-03-13
Abstract: Forming of hollow objects such as tubes is effected in a machine tool which consists of a stationary head in which is mounted one end of the mandrel and a sliding head connected with the stationary head by guide pillars, in which is mounted the radially adjustable tooling and a device for moving the workpiece end over the mandrel at the beginning of the working stroke and remove it from it afterwards.
