Abstract
A compound needle ( ) is provided with a slider ( ) having two slider springs ( ). These are arched away from each other in a section immediately adjoining their insertion funnel ( ). The compound needle has a slider slit ( ), which initially is relatively narrow at its inlet ( ), so that a guide section ( ) has been established there. Thereafter the slider slit ( ) widens, so that a running section ( ) is established. The lateral bulge of the slider springs ( ) is of such a dimension that the slider ( ) runs free in the running section (4 ), and is guided without lateral play in the guide section ( ). The compound needle ( ) also operates precisely in case of tension forces acting laterally on the slider ( ) and requires only a small opening width of its funnel ( ).
