Patent ID: 8871045

Claim:
A method for controlling the winding of an elongated element onto a collection reel with interposition of a service fabric, comprising: rotating the collection reel; simultaneously winding the elongated element and the service fabric onto the collection reel, wherein said simultaneous winding comprises: determining the actual winding diameter of the collection reel; and detecting a variation in length of a portion of the elongated element about to be deposited onto the collection reel; adjusting rotation speed of the collection reel according to said actual winding diameter of the collection reel and to the variation in length of said portion of the elongated element, wherein the elongated element is fed onto the collection reel via a first conveyor belt arranged close to the collection reel and a second conveyor belt operatively arranged between the first conveyor belt and the collection reel, the second conveyor belt pivotally attached to the first conveyor belt at a head end of the second conveyor belt, and the second conveyor belt comprising a detection device for detecting the variation in length of said portion of the elongated element, said detection device being at least one potentiometer pivotally attached to a tail end of the second conveyor belt; wherein said second conveyor belt is moved around the pivotal attachment to the first conveyor belt between a rest position in which the tail end of the second conveyor belt feeds the elongated element to a third conveyor belt at a distal position from the collection reel and an operative position in which said tail end is at a proximal position to the collection reel; and wherein the elongated element is used to make a tyre.
