Abstract
- It has been shown in the preceding paper how high-speed cam systems were desired to give substantial increases in the rate of fabric production of weft-knitting machinery. This paper provides a detailed analysis of the effect of cam shape on the knitting-yarn tensions, machine performance, and individual needle forces. It is explained that, although the yarn tensions developed within the knitting cycle are greater for high-speed cams than for conventional linear cams, these tensions do not affect the resulting fabric appearance or the machine performance. In addition, calculations of individual needle forces and high-speed trials indicate that speeds many times as great as commercial speeds may be achieved with the mathematically designed high-speed cams.
