Abstract
An automatic knitting needle selection device in which a plurality of selectors are provided with protrusions which are normally in contact with corresponding solenoids that are mounted on a swing plate. The selectors are pivotally connected to a pivot shaft at their lower ends and the tilting motion of the swing plate puts the selectors corresponding to energized solenoids out of action while the remaining selectors are pushed upward by another drive means to set the corresponding knitting needles to a knitting position.
Claims12
An automatic knitting needle selection device for forming knitting patterns in a knitting machine, comprising:
- a plurality of vertically oriented knitting needles which can assume either a knit position or a non-knit position,
- a plurality of vertically oriented selectors, provided in one-to-one relation with respect to the knitting needles and pivoted at their lower ends by a pivot shaft, which can assume either a first position adapted for moving the corresponding knitting needles from the non-knit position to the knit position and a second position adapted for not moving the corresponding knitting needles from the non-knit position to the knit position,
- a plurality of solenoids, again provided in one-to-one relation relative to the selectors, for attracting a selected group from the selectors according to a desired knitting pattern,
- a first drive means for moving the selectors other than those in the selected group from the first position to the second position, and
- a second drive means for moving the selectors other than those belonging to the selected group so as to move the corresponding knitting needles from the non-knit position to the knit position.
