Abstract (en)
[origin: EP0887125A2] The drawing tools are fastened to the drive chains, and each drive chain (2,3) is guided at least on the approach side on a constant deflection track (7). To reduce radial acceleration of the chain links in the contact area (8) of the drawing tools (6) on the workpieces, the curve radius of the track is larger than half the distance between the drive chains. The track curve is described by a cycloid function or by a multi- sectional three-centre curve.
