Abstract
A compound needle comprises a closing element with two closing element springs. These are designed to be asymmetrical relative to each other or at least provided with clearances or openings which, during the operation of the compound needle, are made to overlap with a corresponding cutout or other openings in the basic compound needle member, so that deposits can be removed to the needle channel. An asymmetric design of the closing element springs prevents the closing element from being wedged into the closing element channel, even if the deposit removal is incomplete. As a result, the compound needle wear is reduced considerably and the operational safety is increased.
