Abstract (en)
[origin: EP0864382A1] The drawing tools roll on rigid guide tracks in an endless loop so that opposing tools press on the work material and pick it up through frictional contact. The pressing forces of the drawing tools in the area in which the tools come into contact with the tube, are supported by load-bearing rollers which in an endless loop are picked up between the inner surfaces of the draw members and the rigid guide. Two rollers (7) joined at both ends by tabs (9) and located on bolts (8) are assembled to form a carriage-type roller component. A number of those roller components are accommodated on the face side, loosely located one on the other, in the endlessly formed guide tracks (10), which are arranged in the plane of the draw chains (1).
