Abstract
A method and an apparatus to wind a thread on a succession of reels carried by coaxial annuli provided with a clamp member to couple the thread to the reel, the switching-over of the thread from a filled reel to an empty reel being initiated after the detection, by way of a detector, of a predetermined angular position with respect to an associated anvil of the clamp member fixed on the annulus carrying the empty reel. This method and apparatus are for example used to wind electric insulated wire comprising a metallic core around reels.

A method to wind a thread on a succession of reels supported by coaxial annuli rotatively driven and fitted with a peripheral clamp member to couple the thread on the associated reels fixed on annuli, fixed anvils being provided to cut the thread when a reel has been filled to capacity, the switching-over of the thread from a filled reel to an empty reel being initiated after the detection of a predetermined angular position of the clamp member fixed on the annulus associated with the empty reel, this angular position being measured with respect to the associated anvil.
An apparatus to wind a thread, comprising two rotatively mounted annuli with parallel axes, each of them supporting a reel, each annulus being associated with a fixed anvil to cut the thread at the end of the filling of a reel, each annulus having at its periphery a clamp member to couple the thread with the reel, comprising means to detect a predetermined angular position of the clamp member fixed on the annulus associated with the reel to be filled, measured with respect to the associated anvil, and means to initiate the switching of the thread inside the clamp member immediately after the detection.
