Abstract
A yarn supply apparatus for textile machines has a yarn drum (5) carrying a storage winding (10), to which drum the yarn (8) can be supplied at a tangent via a supply guide element, and from which drum the yarn can be drawn off, extending toward the outside, at a run-off speed corresponding to the yarn supply speed, via a run-off guide element (11) located laterally beside the yarn drum (5). In order to assure constantly satisfactory supply conditions even when a yarn drum (5) that effects the advancement of the storage winding solely via the particular shaping of its circumferential surface is used, the supply guide element is in the form of a bowed element (20) having an elongated yarn opening (22), this opening being located with its lengthwise extension transverse with respect to the yarn travel direction and having its lower edge, that is, the edge nearer the yarn drum, located below the upper rim of the yarn drum (5).
