Abstract
This invention provides a yarn feed and controlling device in which a resiliently mounted yarn controlling arm including a yarn guide eye is movable from a first position in which yarn can be continuously fed to a second position in which the yarn is restrained. The device includes a yarn restraining means associated with the yarn controlling arm which serves when the yarn is in the second position to restrain the yarn by applying a clamping force thereto.
Claims9
A yarn feed apparatus for supplying yarn intermittently under a consistent tension, the apparatus including a yarn guide eye resiliently movably mounted on a base, a clamp means located upstream of the guide eye and being operated by the guide eye for intermittently trapping the yarn to prevent its movement through the apparatus, continuously rotatable yarn feed means upstream of the clamp means for positively feeding yarn to the guide eye only when yarn between the feed means and clamp means is under tension, the yarn guide eye being arranged to render the clamp means inoperative while yarn is being pulled from the apparatus and arranged to render the clamp means operative to grip the yarn to prevent further supply of yarn from the apparatus when yarn downstream of the guide eye is relaxed by a predetermined amount.
