Abstract (en)
[origin: EP0432837A2] The present invention relates to a device that may be carriage-mounted (5) and which enables the initial end of the thread (7) to be anchored to the surface of the winding bobbin (1) on which the reel is being formed, this device comprising: an arm (8) which picks up, holds and places the bobbin (1) between the centres of the reel-holder mandrel (22) and the said arm (8) also supports an appropriately-shaped lever (6) which rests initially, with its flat end, against the surface of the bobbin and subsequently rests with a roller (3) fixed freely close to its flat end. The said roller (3) holds the thread tightly against the circumferential surface of the bobbin (1) at a point inside the reel being formed and for the entire time required to wind on the first coils of wound thread; a linkage which has a gripper element (20), a cutter element (2) and a rod-shaped element (10) for moving the thread to the thread anchorage point and start of winding point on the bobbin to form the reel. The said anchorage point of the thread on the surface of the bobbin is located in the section of axial travel of the windings of thread. <IMAGE>
