摘要

The high speeds in warp knitting frequently require technical modifications to be made along the entire production chain - especially in warp preparation. Lace production is one example of this. KARL MAYER's modern lace raschel machines can currently reach speeds of up to 900 min~(-1) and are equipped for highspeed running with an active yarn delivery unit and the Positive Patternbeam Drive (PPD). The PPD electric motor system delivers the exact amount of yarn required, thus minimising stressing of the yarns during processing. However, the PPD can only realise its full potential if the yarn carriers, i.e. the pattern beams, are wound extremely precisely. All the packages on one beam axle must have exactly the same diameter. If the pattern beams also have long running lengths, the setting-up time needed to change the beams at the warp knitting machines can be reduced.
