In the treatment of the pattern producing signals, two kinds of logical elements are avaliable. One is the logical element which has high speed operation time such as transister elements, and the other that has multi-outputs in response to a single input such as the electro-magnetic relays.
In this paper, the circuit for logical operation of pattern producing signals was designed by suitably combining these two logical elements.
The objective of this study was a double jersey circular rib-knitting machine of 20-inch diameter, having the gauge with 12 needles per inch, and 12 yarn feeders.
The circuit was designed to produce two-colour fabric with a design width of 120 wales, three-colors pattern of 60 wales, or four-colour pattern of 40 wales.
The numbers of logical elements of the designed circuit are as follows:
Flip-Flop circuit 267,
AND circuit 315,
OR circuit 128,
NOR circuit 70,
8 T-relay 7,
4 T-relay 5,
2 T-relay 15,
15 M-relay 35,
8 M-relay 4,
2 M-relay 5.
