<p>An apparatus for detaching the terminal spiral winding of yarn from the surface of a spinning cop, utilizes a hook-like yarn catcher element movable vertically along the cop by a pulling device and movable into and out of engagement with the yarn surface of the cop by a spring-loaded guide linkage to which the catcher element is mounted. The guide linkage has two levers pivoted at two respective pivot locations on a base plate and pivotably connected at two spaced pivot locations with the catcher element for coordinated movement to control extension and retraction of the catcher element, the distance between the pivot locations on the base plate being greater than the distance between the pivot locations connected with the catcher element for pivoting the catcher element with an increasing angle of inclination relative to the lengthwise extent of the cop during extension of the catcher element.</p> |
