Abstract
In a knitting machine, a selection latch having two end positions for selecting a knitting-needle is actuated so as to engage a cam which moves the selected latch towards a second end position. The actuation of the selection latch in two stages reduces the displacement brought about by the actuating means and increases the selection frequency. According to the invention the latch is actuated by a thin needle similar to a needle-printer needle, producing an impact on the latch, resulting in transmission of motion with high efficiency and moving the latch into an intermediate position in which the cam brings the latch into its second end position. This substantially eliminates friction between the actuating means and the latch, and enhances the selection frequency.
