Abstract

In a machine for winding spools of textile yarns, a number of winding stations are served in common by a motor driven driving shaft, at each station, the frictional driving cylinder is formed by two half shells clamped securely in position. Worn and/or damaged driving cylinders are replaced quickly and easily. The driving cylinder is secured against rotation and lateral motion, relative to the shaft, at each end by a nut in two halves, held together by two screws, and tightened on the stub of a conical sleeve inside the cylinder journal. The nut is formed in a single piece of a material such as cast iron or a thermosetting resin, which breaks cleanly under a shock load; a fracturing notch is provided on one or both surfaces extending across the full width, in addn. to two tappings and counterbores positioned symmetrically to the central axis of the nut. When made, the nut is clamped parallel with the fracturing notch aligned to a supporting edge, as in a vice, and broken by a sharp blow with a hammer. The fracturing notch is in the form of a bevelled indent extending on both sides of the bore of the nut, and may be located on both faces, so that the nut breaks easily. This makes it unnecessary to remove the driving shaft from the frame for the replacement of the spool driving cylinders, and prevents any damage to the screws, sleeves, etc. so that there is no need for adjustments, such as machining, rethreading, etc.
