ABSTRACT:
A yarn tensioning device having a yarn tensioning element mounted on a seat within a housing through which the yarn travels. A cap is mounted in the outlet of the housing and has a smaller opening than the size of the tensioning elements to prevent replacement or addition of elements and is secured in the housing to prevent removal. The cap has a tapered inner surface and two sequential frustoconical outer surfaces forming a juncture therebetween. The annular peripheral surface of the cap is relieved. The tensioning element is elongated and shaped to preclude rotation during operation and particularly when yarn travel stops during operation of the associated equipment.
