The linear motion of the drawing slides is produced by guide curves provided on a rotating cylinder either in form of protrusions (40) or in form of grooves (43). The curves are in positive driving contact with lugs (34,35) connected to the drawing slides. The relevant feature of the design is that with the exception of turning point areas (41,42) the flanks of the curve are undercut so that the corresp. carrier lug is not in contact with the flank. |
