ABSTRACT:
In the needle selection device on a knitting machine there are provided knitting needles and jacks arranged to be displaceable in needle channels, and flexible selection shanks with operating butts mounted on the knitting needles or jacks. The selection shanks can be lowered in the needle channels by pressure cam elements moved over the needle channels, and selection elements are also provided controlled selectively by selection magnets and moved over the needle channels. In order to achieve a structure for the device which is mechanically structurally simple, displaceable selection jacks with selection butts are arranged in the needle channels to engage above or below the flexible selection shanks, the selection elements are double-armed pivotable selection flaps with inclined contact surfaces for the displacement of the selection jacks, and the selection magnets are flap-anchoring magnets or solenoids whose armatures when energized hold the selection flaps in the vertical position for forward displacement of the selection jacks.
