A compound needle (1) is provided with a slider (8) having two slider springs (11, 12). These are arched away from each other in a section immediately adjoining their insertion funnel (28). The compound needle has a slider slit (4), which initially is relatively narrow at its inlet (15), so that a guide section (4a) has been established there. Thereafter the slider slit (4) widens, so that a running section (4b) is established. The lateral bulge of the slider springs (11, 12) is of such a dimension that the slider (8) runs free in the running section (4b), and is guided without lateral play in the guide section (4a). The compound needle (1) also operates precisely in case of tension forces acting laterally on the slider (8) and requires only a small opening width of its funnel (28).
A compound needle (1), in particular for hoop-forming textile machines, having a needle body (2), whose shank has a hook (3) with a tip at one end, having two slit walls (6, 7) provided on the shank and parallel with each other, which between themselves delimit a slider slit (4) of a width (W1, W2) which corresponds to the distance between the slit walls (6, 7),
