Abstract
Abstract There is disclosed a device for feeding yarn from a supply thereof to a textile producing machine. A storage drum is provided about which there orbits yarn winding means whereby the yarn is wound onto the drum tangentially for subsequent axial withdrawal on its way to the textile producing machine with a minimum of tension. A feeler biased against the drum detects the presence of a predetermined minimum quantity of yarn wound onto the drum after which it controls, through time delay means, additional winding for a predetermined time period. There are disclosed a number of different forms of winding means including the use of a rotatably mounted disk and rotatably mounted annular member, each of which carries the storage drum which is prevented from having significant rotation.
