Abstract
A compound needle ( ) is provided with a slider ( ) having two slider springs ( ), whose ends constitute an open funnel pointing toward the hook ( ). The ends, or legs ( ), constituting the funnel, are flattened. Therefore, starting at a starting point, the thickness of the material is reduced in the tapered area ( ) toward the ends of the slider springs ( ). By means of this a correct functioning of the compound needle is also provided if the slider ( ) is not completely centered. Moreover, it is possible to improve the easy movement of the slider ( ) in the slider slit in that the funnel, formed by the legs ( ), can be embodied to be narrower at a constant width, than without the taper of the slider springs ( ).
