Abstract: According to one embodiment, a winding device includes a supporting part, a pressing part, a movement part configured to move a positional relationship between the supporting part and the pressing part, a control part, a target movement speed calculation part configured to detect a target relative movement speed of the pressing part with respect to the supporting part, a wire feed speed detection part configured to detect a feed speed of the wire, a deviation amount calculation part configured to calculate a difference between a detection result of the target movement speed calculation part and a detection result of the wire feed speed detection part, and a determination part configured to determine that the wire has deviated from the movement path.

Abstract: Although many conventional ribbon winding preventing methods have substantially solved a ribbon winding problem in terms of the appearance of a package, there is still a large difference between a ribbon winding layer and the other layers in, for example, unwinding performance for fast unwinding during a postprocess. In a configuration for using a traverse groove 11 formed in a traverse drum 6 to traverse and wind a yarn into a package 3, the traverse drum 6 has a plurality of continuous traverse grooves 11 for different winding values formed therein. This configuration also has means 24 for switching a yarn path to determine which of the plurality of continuous traverse grooves 11 for different winding values used to traverse the yarn. Means for detecting a diameter at which ribbon winding may occur is also provided to effect such control that the winding number for the traverse drum 6 is changed when a package diameter is close to the ribbon winding diameter.

Abstract: A method for winding a continuously advancing yarn to a cross-wound package on a rotating tube wherein the yarn is deposited on the tube during the winding of the package within a winding range. Directly before the winding cycle, a yarn reserve wind forming a trailing yarn end of the package is deposited outside of the winding range. In this process, the yarn is guided by a yarn guide that is movable substantially parallel to the tube surface. In accordance with the invention, the yarn guide is reciprocated at different guiding speeds for purposes of securing the trailing yarn end on the circumference of the tube with at least some yarn winds of the yarn reserve wind.
