Abstract

Abstract The present invention provides a method and apparatus for verifying knitting machine data which has been prepared from a pattern drawing and will be used by an electronically controlled circular knitting machine or by a pin setting machine for setting pins in pattern drums or wheels. The knitting pattern data includes knit and non-knit indications which are stored at memory locations on a suitable memory means such as punched paper tape, magnetic tape, or a magnetic disc or drum Verification is effected by logically examining all of the knit and non-knit instructions for each stitch of each stitchrow of the pattern defined by the knitting pattern data. If the combination of knit and non-knit instructions for a stitch does not conform to the format for the type of fabric to be knitted, then readout devices indicate the stitchrow and stitch number where the error exists.

Claim 4
Dependent Claim 32 words
An apparatus as set forth in claim 1 further including means for indicating the stitch and stitchrow for which the knit and non-knit indications are not in accordance with the predetermined pattern.
Claim 5
Dependent Claim 36 words
An apparatus as set forth in claim 1 further including readout means for indicating the knit and non-knit indications in a combination of knit and non-knit indications which is not in accordance with the predetermined pattern.
Claim 6
Independent Claim 336 words
An apparatus for detecting the presence sensing an error in a selected one of a plurality of sets of pattern data, each set of which represents a different knitted pattern and is utilized to effect activation of feeders in a plurality of groups consisting of a number of feeders determined by the pattern to knit different stitchrows of the pattern, said apparatus comprising sensor means for sensing knit and non-knit indications in the selected set of pattern data, said sensor means including means for effecting sequential sensng of knit and non-knit indications associated with each feeder of a feeder group for a stitchrow of the pattern represented by the selected set of pattern data, a plurality of registers each of which is capable of holding the knit and non-knit indications associated with a feeder for a stitchrow of the pattern represented by the selected set of pattern data, circuit means for associating a different one of said registers with each feeder of a feeder group and for transmitting knit and non-knit indications for each feeder of a feeder group from said sensor means to the associated one of said registers, verification means for determining if the combination of knit and non-knit indications associated with each feeder of one feeder group for a stitch of the stitchrow corresponds to a combination of knit and non-knit indications which is in accordance with the format associated with the selected set of pattern data, said verification means including logic means for detecting combinations of knit and non-knit indications which are not in accordance with the format associated with the selected set of pattern data, pattern selector means for setting said logic means to detect combinations of knit and non-knit indications for any one of the patterns associated with the plurality of sets of pattern data, and means for effecting the transmission from a plurality of said registers to said verification means of knit and non-knit indications associated with each feeder of a feeder group for a stitch of the stitchrow.
