Abstract
A method for knitting a flat knitted fabric, wherein all knitting needles of the flat knitting machine are individually connected to an actuator, and each actuator of the corresponding knitting needle is activated in accordance with the predetermined knitting plan, and a flat knitting machine for implementing the above-mentioned knitting method. Preferably a linear direct current motor is used as the actuator. The flat knitting machine in accordance with the present invention can be operated at a higher speed than known conventional knitting machines and can provide a novel flat knitted fabric which cannot be knitted by the conventional flat knitting machine, by individually changing a retracting length of a needle.
Claims15
A method for knitting a flat knitted fabric by using a flat knitting machine comprised of a plurality of knitting needles each having an actuator and arranged, in parallel in a plane;
- a knitting needle guiding member slidably supporting said plurality of knitting needles, extended in either direction along said plane and defining each distance between adjacent knitting needles;
- and a running device having at least one thread feeding unit and reciprocally moving in either direction along said knitting needle guiding member, wherein a position of the thread feeding unit of the running device is detected and a signal in accordance with a predetermined knitting plan is input to the actuator of each knitting needle corresponding to the position detected of the thread feeding unit, whereby a sliding movement in accordance with said predetermined knitting plan is applied to said knitting needle to knit said flat knitted fabric.
A flat knitting machine including at least one knitting mechanism comprised of a plurality of knitting needles arranged in parallel in a plane and a knitting needle guiding member slidably supporting said plurality of knitting needles, extended in either direction along said plane and defining each distance between adjacent knitting needles to form a knitting loop;
- at least one running device capable of reciprocally moving in either direction along said knitting needle guiding member, at least one thread feeding unit being provided in said running device;
- an actuator for slidably moving a corresponding knitting needle and connected to each knitting needle of said plurality of knitting needles;
- and a controlling apparatus having a memory storing a predetermined knitting plan and controlling operation of said actuator in synchronism with the reciprocal movement of said thread feeding unit in accordance with the predetermined knitting plan.
