ABSTRACT:
An arrangement for fastening in place yarn bobbins in looms, in which a support member fastened to the loom plate holds a shaft member at an inclined angle. A lower ring-shaped bobbin holder passes over the shaft member and supports the lower end of a bobbin held on the shaft member. The lower bobbin holder is freely axially movable on the shaft member. A spring is disposed between the shaft support and the lower bobbin holder. The bobbin is held in place at the upper end by a replaceable ring-shaped member having a predetermined taper to accommodate bobbins of various diameters, lengths and shapes. A locking ring bearing against a projection on the free end of the shaft, holds the bobbin together with the lower and upper retaining rings in place on the shaft. Spacers are applied on the shaft between the upper replaceable ring and the locking ring, as required, to accommodate bobbins of varying lengths.
