Computerized Pattern Designing and Production System

Part 3 : Development of Electronic Weft Knitting Machine

Abstract

To achieve a technological progress in a pattern designing and production field of weft knitting, computerized weft knitting machinehas been developed. The main features of the electronic weft knitting machine are :
(1) A pattern control part and mechanicalcontrol part of conventional jacquard weft knit-ting machine are computerized, then weft knitting machine can be operated by the aid ofpattern information tape, knitting stitch information tape and machine control tape.
(2) A pulse-motor type actuater, mountedon the carriage of the electronic weft knitting machine, selects the each knitting needle offront or back needle bed, and then produces aknitting pattern.
(3) Since a conventional jacquard weft knit-ting machine is easy to modify, this electronicweft knitting technique is highly processablefor a variety of weft knitting machine types.
(4) Specification : Gauge=8/inch, feed = upto 6 colours, cam=single 2-step RAHBEN cam, width =100 cm/needle bed, speed=approx. 24courses/min.
(5) Using the electronic weft knitting machine and pattern analyser, only one operatorcan quickly (within 1 hour) operate from patternanalysing to electronic weft knitting of large pattern, then making possible time-and laboursaving, worthy weft knit production and quickdelivery to meet market needs.
