Abstract

In a flatbed knitting machine with electronic control and comprising programmable fixed-word stores and freely accessible stores, all the data for the operation of the machine is split into five divisions, namely motif pattern draft, needle set-up, knitting plan, function number schedule, and plan run. Data for the knitting of standard patterns, comprising the whole of the knitting plan division and part of the function number schedule division, is stored permanently in the fixed word stores. The stored data for the operation of the machine can be extracted and archived. Parts of the data of the divisions can be extracted to compose new patterns. Certain knitting courses can be suppressed and certain needle groups can be selected for adjustment without altering the already stored data. Information as to gauge can also be entered.

Dependent claims

In an electronic control system for a flatbed knitting machine with electronic control, said control system being of the type having memory means for storing a first division of data containing motif pattern draft data, a second division of data containing needle set-up data, a third division of data containing knitting plan data, a fourth division of data containing function number schedule data and a fifth division of data containing plan run data, and data entry means for entering data into said memory means, said knitting machine being of the type wherein a pattern is knitted in accordance with selected data retrieved from said memory means according to a knitting program, said knitted pattern including at least one of a plurality of standard patterns each defined by a portion of the data in said third division and a portion of the data in said fourth division, the improvement comprising:

said memory means comprising a freely accessible memory, e.g. a random access memory (RAM), for storing said first, second and fifth data divisions;
and
a programmable fixed-word memory, e.g. programmable read only memory (PROM) for storing at least said third division of data and the portion of said fourth division of data necessary to define said standard patterns.
