Abstract
The invention relates to a circular knitting machine and a method carried out thereon for kniting patterned knitwear with a plurality of yarns. So that it is also possible to make patterns in which any yarns (25) are not worked by a plurality of adjacent needles (12), the floats (26) resulting therefrom are parted from inside the needle circle (10a) and the yarn ends (28) thereby resulting on the side of the associated yarn guide (24) are constantly retained in the capture region of the needles (12) selectable by the selector device for yarn reception. The patterning can thus be effected solely with the aid of the selector devices. Yarn change devices or ring guide bars are not needed (FIG. 2).
Claims11
A method for fabricating a knitted fabric and for producing a pattern therein with a plurality of yarns of different kinds on a circular knitting machine having a needle carrier, a plurality of knitting needles movably mounted on said needle carrier and arranged along a needle circle, a plurality of yarn guides for feeding one of said yarns each, said yarn guides being arranged along said needle carrier and outside of said needle circle and being mutually spaced from each other, and a plurality of means arranged along said needle carrier for controlling, at each of said yarn guides, first needles such that they receive a yarn from said yarn guides and bind said yarn into the fabric and for also controlling second needles such that the same are unable to receive a yarn at said yarn guides but let the yarn float;
- said method comprising the steps of:
- knitting said fabric with said needles from said yarns;
- selecting said first and second needles at each of said yarn guides in accordance with said pattern;
- parting the floats of said yarns, when said floats attain a predetermined length, inside said needle circle into first yarn ends being connected to the fabric and second yarn ends being connected to one of said yarn guides such that said second yarn ends are in a position crossing said needle circle;
- retaining said second yarn ends without actuation of said yarn guides in said needle circle crossing positions such that the same are adapted to be received by said first needles but are unable to be received by said second needles;
- and retaining said second yarn ends in said positions at least long enough to be received by a selected needle and bound into said fabric.
A circular knitting machine for fabricating a knitted fabric and for producing a pattern therein with a plurality of yarns of different kinds, comprising:
- a needle carrier;
- a plurality of knitting needles movably mounted on said needle carrier and arranged along a needle circle;
- a plurality of yarn guides for feeding one of said yarns each, said yarn guides being arranged along and outside of said needle circle and being mutually spaced from each other;
- a plurality of means arranged along said needle carrier for controlling, at each of said yarn guides, first needles such that they receive a yarn from said yarn guides and bind said yarn into the fabric and also for controlling second needles such that the latter are unable to receive a yarn at said yarn guides but let the yarn float;
- means for selecting said first and said second needles for each of said yarn guides in accordance with said pattern;
- at least one parting device arranged inside said needle circle for parting said floats of at least one of said yarns, when said floats attain a predetermined length, inside said needle circle into first yarn ends associated with the fabric and second yarn ends being connected to one of said yarn guides such that said second yarn ends are in a position crossing said needle circle, said parting device being assigned to a predetermined chord of said needle circle such that the floats are parted on attaining a length corresponding to said chord and that said second ends formed thereby are retained in a position crossing said needle circle such that the same are adapted to be received by said first needles but are unable to be received by said second needles.
