AXIAL DISC BRAKE AND THREAD FEED FITTED THEREWITH
In an axial disc brake (B), especially for a thread feed, having dynamically balanced and dimensionally stable braking surfaces (1, 2) pressed against each other yieldingly by under a predetermined pressure, one of which has a central withdrawal aperture and is arranged on a brake component which is supported to move at least axially, one braking surface (1) is spherically convex and the other (2) is tapered with a taper axis fitting at least approximately in the axis (3) of the disc brake (B) and the taper generator in the contact region (C) of the braking surfaces (1, 2) is a tangent (T) of the generating circle of the spherically convex braking surface (1). The axial disc brake (B) is preferably fitted on the front of a storage drum (D) of a thread feed (F) for a gripper or shuttle loom in such a way that the thread unwinding over head clockwise from the storage drum (D) and rotating along a thread guide (6) is taken directly without deflection into the contact region of the braking surface and is only gently deflected axially again after passing the contact region.
