Description

[Detailed description of the invention] This invention relates to a needle selection device for a flat knitting machine.

For pattern knitting, a knitting needle and a needle jack connected to the knitting needle or not connected in the needle groove, the needle jack being made flexible, and the needle When the middle position in the longitudinal direction of the jack is pressed down using a jack presser, which acts to push down the upper surface of the needle jack within the same needle groove, the needle jack, which normally protrudes from the surface of the needle bed, is pressed down. The knitting needles in the same needle groove to which the needle jack is associated can be kept in a non-working position in the working area of the needle lock and the transfer lock. The needle selection device has already been developed by JP-A-Sho.
50-36757 and other publications.

However, in conventional devices, except those using an electromechanical needle selection mechanism (for example, see JP-A-54-68440), needle selection for pattern knitting is performed by changing the butt position of the jack presser. That is, this had to be done only by changing the longitudinal position of the needle groove in the jack presser itself. Therefore, when selecting needles using this method, when the number of needle selection stages is increased, the position on the needle jack where the front end of the jack presser acts to push down changes greatly, so the needle jack The length must be increased. For this reason, in the conventional device, the number of needle selection stages along the advancing and retracting direction of the jack presser acting on the needle jack was at most three to four stages.

One purpose of this invention is that multi-stage needle selection, such as 5 to 6 stages, can be performed without changing the position where the front end of the jack presser directly or indirectly acts on the needle jack within the needle groove. The objective is to provide a needle selection device that is possible.

Another object of this invention is to make it possible to select from multiple stages the position where the front end of the jack presser acts directly or indirectly on the needle jack within the needle groove. Another object of the present invention is to provide a needle selection device that is capable of performing needle selection in multiple stages in addition to the multistage needle selection described above.

That is, according to the needle selection device according to this invention, for example, multi-stage needle selection for pattern knitting and two-stage needle selection for hem elastic knitting are made independent,
Although this can be done extremely easily, the needle selection device of this invention selectively controls the butt of a flat knitting machine having a needle jack as described above by acting directly or indirectly on the needle jack.
