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.

The invention claimed is: 1. 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. 2. The weft knitting machine with a density adjusting function according to claim 1, wherein the density correction means performs density correction such that, when circularly knitting a tubular fabric in one direction, the density at the knitting-start section is smaller and the density at the knitting-end section is larger as compared with the density at the knitting-middle section. 3. The weft knitting machine with a density adjusting function according to claim 1, wherein the density correction means performs density correction such that, when knitting a flat fabric, the density at the knitting-start section is larger and the density at the knitting-end section is smaller as compared with the density at the knitting-middle section. 4. The weft knitting machine with a density adjusting function according to claim 1, wherein the density correction means is configured such that, when, at the knitting-start section of a next course, stitches are formed onto stitches formed at the knitting-end section of a current course, the density at the knitting-start section is larger and the density at the knitting-end section is smaller as compared with the density at the knitting-middle section, and such that, when, at the knitting-start section of the next course, stitches are formed onto stitches that are different from the stitches formed at the knitting-end section of the current course, the density at the knitting-start section is smaller and the density at the knitting-end section is larger as compared with the density at the knitting-middle section. 5. The weft knitting machine with a density adjusting function according to claim 1, further comprising density correction data storage means for storing, as variables of knitting conditions, correction values of the densities at the knitting-start section and the knitting-end section in relation to the density of the knitting-middle section. 6. 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. 7. 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. 8. The program of a weft knitting machine according to claim 7, wherein the density correction command performs density correction such that, when circularly knitting a tubular fabric in one direction, the density at the knitting-start section is smaller and the density at the knitting-end section is larger as compared with the density at the knitting-middle section. 9. The program of a weft knitting machine according to claim 7, wherein the density correction command performs density corrections such that, when knitting a flat fabric, the density at the knitting-start section is larger and the density at the knitting-end section is smaller as compared with the density at the knitting-middle section. 10. The method of claim 6, wherein in the correcting step, density correction is performed such that, when knitting a flat fabric, density at the knitting-start section is large and density at the knitting-end section is small as compared with the density at the knitting-middle section. 11. The method of claim 6, wherein in the correcting step, density correction is performed such that, when circularly knitting a tubular fabric in one direction, density at a knitting-start section is small and density at a knitting-end section is large as compared with the density at the knitting-middle section.
