Abstract
A yarn storage and supply apparatus, in particular for textile machines, has a storage drum (4) in the manner of a cage with rods having a number of elongated yarn support elements located at identical radial intervals from the drum shaft (2) and distributed uniformly in the circumferential direction. Each of the yarn support elements, extending substantially in the drum shaft direction and secured to a drum body (13, 14, 15), is in the form of a narrow yoke (16), which on the yarn delivery side has a radially inwardly tapering region (17), acting as a run-on incline for the oncoming yarn (8), and adjoining it a substantially straight region (19), forming a yarn support region for a plurality of loops of yarn windings (20), the straight region being followed by a radially protruding circular, continuous yarn run-off rim (12). To prevent accumulations of fluff and so forth, the yarn run-off rim (12) is adjoined toward the run-on inclines of the yokes by a radially inwardly inclined circumferential face (24) on a rotationally symmetrical cover (23 ) coaxial with the drum shaft, which at least in the regions located between adjacent yokes (16) is continuous in the circumferential dire…
