摘要:A simplified strand storage and feeding device having a rotatable spool about which a traveling yarn is transiently wound while being fed to a textile machine, utilizes a noval driving arrangement for rotation of the spool, including a pulley operatively affixed to the spool and having plural radial teeth circumferentially spaced about one side of a belt receiving recess in the pulley and a driving belt having compatible edge notches meshing with the pulley teeth. The edge notched configuration of the belt provides positively timed driving of the device while also being spliceable by mechanical interconnection of separate belt ends, so that the belt may be of non-endless form for ease of installation and breaks therein may be easily repaired by splicing. A slidably movable yarn withdrawal guide eyelet is provided for withdrawing yarn from the spool either tangentially or generally axially therefrom for operation of the device in either a positive or demand feeding mode. Two forms of pulley and spool assemblies are disclosed which eliminate the use of a separate yarn winding displacement member and are resultantly simplified, compact and less expensive than conventional devices.
