Abstract
A double knit circular knitting machine is provided having a first needle bed in which transfer needles are mounted and a second bed in which ordinary needles devoid of transfer function are mounted in a double density to that of the transfer needles for knitting a high density fabric in any one of several predetermined patterns. A method of knitting high density fabric is provided utilizing such transfer and ordinary needles to form courses of stitch loops and, as dictated by the pattern, to transfer stitch loops from selected transfer needles to correspondingly selected ordinary needles.
Claims13
A circular knitting machine for knitting high density fabrics comprising
- a first needle bed having first needle grooves therein, said first needle grooves having a first gauge suitable for transfer needles,
- a second needle bed operatively associated with said first needle bed for the knitting of double-knit or single-knit fabric and having second needle grooves therein, said second needle grooves having a second gauge double said first gauge so that said second needle bed can accommodate twice as many needles,
- first knitting needles slidably mounted in said first grooves in said first needle bed and having transfer pockets thereon to provide for the transfer of stitch loops from said first needles, and
- second knitting needles slidably mounted in said second grooves in said second needle bed and being devoid of any transfer function, said second knitting needles being adapted to receive transferred stitch loops from said first knitting needles.
A method of knitting high density fabrics on a circular knitting machine having first and second needle beds with first and second needle grooves therein, the first needle grooves in said first needle bed having a first gauge and the second needle grooves in said second needle bed having a second gauge double said first gauge, said method comprising
- providing said first needle bed with a transfer needle in each of said first grooves and said second needle bed with an ordinary needle in each of said second grooves so that there are twice as many ordinary needles as there are transfer needles,
- moving said needles in said grooves while supplying yarn thereto to knit a high density fabric in accordance with a predetermined pattern, and while transferring stitch loops from selected transfer needles to correspondingly selected ordinary needles as dictated by the predetermined pattern by raising the ordinary needles to a tuck position while opening latches thereon, extending the selected transfer needles to a transfer position, raising the selected ordinary needles to a capture position to capture the stitch loops to be transferred, withdrawing the selected transfer needles to shed the stitch loops therefrom and lowering the selected ordinary needles with the transferred stitch loops thereon.
