FIBER BUNDLE WINDING DEVICE
A fiber bundle winding device includes: a traverse guide configured to guide a fiber bundle to a bobbin; and a controller configured to control the traverse guide according to a rotation of the bobbin. The traverse guide is movable parallel to a center axis of the bobbin. The controller can perform: first movement control that moves the traverse guide to wind the fiber bundle onto the bobbin in a predetermined first area extending in a direction of the center axis of the bobbin; and second movement control that moves the traverse guide to wind the fiber bundle onto the bobbin in a second area being smaller than the first area and having ends that are located within the first area and at different positions from respective ends of the first area. The first movement control and second movement control are performed at a ratio of N:1 (N is an integer more than 1).
Method for winding an elastic yarn package
A method is provided for winding an elastic yarn into a cylindrical substantially straight-ended yarn package. The method includes feeding an elastic or elastomeric yarn at a substantially constant speed to a tube core to form the yarn package. The yarn package is rotated such that the yarn package with a substantially constant surface speed. The yarn is wound to form layers of helical coils, while providing a helix angle variation of greater than zero up to +/80%.
Method for adapting a changing movement of a thread to a flange spool and spooling device
A method for adapting a travel end position of a changing movement of a thread to a flange spool includes means of which the thread is moved back and forth during a spooling operation along a rotation axis of the flange spool relative to the flange spool by means of a changing thread guide. The flange-side travel end position can be moved away from the flange of the flange spool in an axial direction when the thread tension decreases when the thread is moved away from the flange-side travel end position. Also, the flange-side travel end position can be moved by means of the changing thread guide in an axial direction towards a flange of the flange spool when the thread tension increases when the thread is moved away from the flange-side travel end position. Included is a spooling device for carrying out the disclosed method.
