Abstract
A plurality of warp knitting machine needles are aligned in a parallel array in a like plurality of needle bar grooves. The needles each have a striker detent projection which mates with an abutment surface of the bar at the groove. The striker projection forms a key which is shaped to torque the needle against the groove in response to a force applied to a force transfer projection extending from the needle on a side opposite the striker projection. A convex tensioning device is between the force transfer projection and the bar and when compressed by a screw threaded to the bar spreads the device and forces the needle into the groove. The striker and the force transfer projection are axially aligned at the same or different needle shaft positions in different embodiments. A collar on the screw between the device and bar limits the maximum force applied to the needle.
