Abstract:
1. A compound needle used for a knitting machine comprising a needle body having a hook at a front end thereof and a slider having a tongue formed by two blades, the slider being supported on the needle body to be freely advanced and retracted along a surface of the needle body serving as a supporting surface so that the needle hook can be opened and closed with the slider tongue by a relative movement between the needle body and the slider; the tongue being provided, at a front end thereof, with a drop-loop preventing step to prevent a loop retained on an upper edge of the tongue from slipping off from the front end of the tongue; and the hook being provided, on an outer edge portion thereof extending from a sharp-pointed tip of the hook to a top of the hook, with a loop escape surface to hide the drop-loop preventing step when the hook is closed by the tongue, wherein there is provided tongue lowering means for lowering the front end of the tongue so that a height between a bottom of the needle body and a top of the drop-loop preventing step is lowered more when the slider is in a knock-over position than before the slider arrives at the knock-over position and also the top of the drop-loop preventing step positioned at the knocked-over position can be positioned at a lower level than the top of the hook.
