Abstract
In order to verify the new pattern-producing methods for the circular rib-knitting, proposed previously by the authors1, 3), a prototype unit for the pattern-producing controller was deviced, and some experiments are performed on the apparatus with three-color pattern (a circular rib-knitting machine of 20-inch diameter, the gauge with 12 needles per inch, and 6 yarn feeders).
The results showed the high utility of the new pattern-producing methods, and it was confirmed that not only the enlargement of pattern area, simplification and rapidification of pattern change are promoted but also some new patterns can be knitted by this method.
Moreover, it is considered that by the utilization of the industrial digital computer as the general pattern controller, the multification of pattern varieties is promoted and lower cost for equipment can be expected by adopting the concentration control method for several knitting machines
