Abstract
A decision is made as to whether a fabric to be knitted is tubular or flat, and density is corrected such that knitting-start density is smaller and knitting-end density is larger for a tubular fabric. Knitting-start density is larger and knitting-end density is smaller for a flat fabric. A variable density section is provided between the end part and the central part of the fabric thus correcting the density gradually. Stitches at the end part of the fabric are prevented from becoming uneven as compared with the stitches in the central part without requiring additional hardware.
Claims11
A weft knitting machine with a density adjusting function, which performs knitting by reciprocally moving a carriage having a stitch cam over at least a pair of needle beds,
- the weft knitting machine comprising density correction means for correcting needle density of specified areas, which are a knitting-start section and a knitting-end section of a fabric, in accordance with the type of the fabric to be knitted, whereby density at the knitting-start section and density at the knitting-end section are corrected to be in directions opposite to each other such that the density at the knitting-start section is smaller or bigger and the density at the knitting-end section is larger or smaller as compared with density at a knitting-middle section.
A knitting method of knitting a fabric using a weft knitting machine, which performs knitting by reciprocally moving a carriage having a stitch cam over at least a pair of needle beds, said method comprising steps of:
- correcting, in accordance with the type of the fabric to be knitted, needle density of specified areas, which are a knitting-start section and a knitting-end section of a fabric, so as to be in directions opposite to each other in the knitting-start section and the knitting-end section, such that the density at the knitting-start section is smaller or bigger and the density at the knitting-end section is larger or smaller as compared with density at a knitting-middle section.
A program, on a computer-readable medium, of a weft knitting machine that performs knitting by reciprocally moving a carriage having a stitch cam over at least a pair of needle beds,
- the program comprising a density correction command for correcting, in accordance with the type of fabric to be knitted, needle density of specified areas, which are a knitting-start section and a knitting-end section of the fabric, so as to be in directions opposite to each other in the knitting-start section and the knitting-end section such that density at the knitting-start section is smaller or bigger and density at the knitting-end section is larger or smaller as compared with density at a knitting-middle section.
