■ For the computerizing equipment for knitting machinery

The equipment is intended for a needle selection system computerized for the knitting machinery.

When the patterning data prepared by means of a computer-aided pattern preparation device designed especially for this system are read in by the system installed on a knitting machine, needle selection is performed by the knitting machine on the basis of such patterning data so that it will knit fabrics containing the pattern designs as seen on the display screen of the
computer-aided pattern preparation device.







Only a few years back, Maruzen Sangyo Co., Ltd. used to build various kinds of single cylinder hosiery knitting machines mainly, such as, jacquard hosiery knitting machine with pattern drums, dial and needle cylinder machine for lacy socks, spiral hosiery machine, a true Argyle socks knitting for producing socks with overchecked solid colour diamond patterns. It is therefore thoroughly acquainted with the patterning mechanism employed for the knitting machinery. In developing the computerizing equipment, it has solved lots of technical problems in electronic and mechanical respects to complete practical heavy duty
equipment, while embracing all the experience, knowledge and skills obtained through building of the knitting machinery.

The equipment can be available for computerizing not only the machines of first hand but also the machines with mechanical patterning device already running in the hosiery factory. The machine with mechanical patterning device is limited in the pattern area and number of patter yarns available for creating pattern designs. In changing pattern designs, moreover, it is true that it usually took two days or three at least even for an expert knitting mechanic to complete the job.

Some 8.000 and odd units have been manufactured and delivered since it was developed in 1983 to customers in Japan, America, Italy, Korea and China and other Asian countries for computerizing large and small diameter circular knitting machines centering primarily on the half hose knitting machines, circular piece-goods jacquard knitting machines and garment length machines.
