Abstract
A tubular knitted fabric is broadened while fully preventing generation of open gap. Yarn is hooked on a needle of a second needle bed and twisted to form a loop, and this loop is transferred onto a first needle bed to become a broadening loop. A subsequent stitch is formed on the broadening loop and transferred back to the second needle bed. Yarn is hooked again on a needle of the second needle bed and twisted to form a loop, and this loop is transferred to the first needle bed to become a broadening loop.
Claims5
A broadening method of using a flat knitting machine having at least a pair of abutting needle beds, each having a large number of needles, holding a first knitted fabric on needles of a first needle bed, holding a second knitted fabric on needles of a second needle bed, and broadening a tubular knitted fabric comprising said first knitted fabric and said second knitted fabric, and
- said broadening method comprising repeating a series of steps for forming a broadening stitch, a series of steps for transferring the broadening stitch thus formed, and a series of steps for compensating for broadening, and
- said series of steps for forming a broadening stitch including
- feeding yarn to needles holding the first knitted fabric to form a new row of stitches on the first knitted fabric, and feeding yarn to an empty needle outside the first knitted fabric on the second needle bed to form a hooked part.
- twisting said hooked part on the second needle bed to make prolongations on both sides of the hooked part cross and change it into a loop, and feeding yarn to needles holding the second knitted fabric to form a new row of stitches on the second knitted fabric, and
- transferring said loop onto an empty needle being outside the first knitted fabric on the first needle bed to make it a broadening loop, and
- said series of steps for transferring said formed broadening stitch including
- feeding yarn to needles holding the first knitted fabric except a needle corresponding to said broadening loop to form a new row of stitches on the first knitted fabric.
- feeding yarn to the needle corresponding to said broadening loop on the first needle bed to form a stitch subsequent to the broadening loop, and feeding yarn to needles holding the second knitted fabric to form a new row of stitches on the second knitted fabric, and
- transferring the stitch subsequent to said broadening loop on the first needle bed to an empty needle outside the second knitted fabric on the second needle bed to broaden the second knitted fabric, and
- said series of steps for compensating for broadening including,
- feeding yarn to needles holding the first knitted fabric to form a new row of stitches on the first knitted fabric, and feeding yarn to an empty needle outside the first knitted fabric to form a hooked part,
- twisting said hooked part on the second needle bed to change it into a loop, and feeding yarn to needles holding the second knitted fabric to form a new row of stitches on the second knitted fabric, and
- transferring said loop on the second needle bed onto an empty needle outside the first knitted fabric on the first needle bed to broaden the first knitted fabric.
