  • Method for producing tubular knitted fabric and weft-knitting machine
    Patent number: 7716954
    Abstract: A needle engaging with a loop at least lastly formed on a fabric formed just before inversion of a carriage is pulled by a pull-down cam formed in a composite cam system of the carriage while feeding a yarn to an opposite needle. When a feeding direction of a yarn fed from a yarn feeder is inverted accompanied with the inversion of the carriage, the tension force applied to the yarn is intensified to prevent tightening of the stitch of the knitted fabric.
