Abstract
The multibed flat knitting machine has upper needle beds, lower needle beds disposed under the upper needle beds, respectively, with their heads located adjacent to those of the upper needle beds. Knock-over bits are placed in the heads of the upper needle beds so as to slide parallel to the sliding directions of the upper needles. The knock-over bits are capable of being advanced to a position where the loop holders of the knock-over bits are beyond a corresponding position of the needle hooks of the advanced upper needles to support the needle heads of the upper needles of the upper needle beds.
Claims6
A method of knitting a weft knitted fabric using a multibed flat knitting machine, comprising:
- providing an upper needle bed having a head portion,
- providing a lower needle bed having a head portion under the upper needle bed, the head portion of the lower needle bed being located adjacent to the head portion of the upper needle bed,
- providing an upper needle having a needle hook, the upper needle defining a sliding direction and an advanced position,
- providing a lower needle for stitching,
- providing a knock-over bit located in the head portion of the upper needle bed and having a loop holder, the knock-over bit being slidable in a direction parallel to the sliding direction defined by the upper needle,
- advancing the knock-over bit to a position in which the loop holder of the knock-over bit supports the needle head of the upper needle when the upper needle is in the advanced position,
- raising the lower needle, and
- retracting the knock-over bit to a position in which a collision between the lower needle and the knock-over bit is avoided when the lower needle is raised.
