Abstract: The invention relates to a method for controlling a winding machine for winding a continuously fed winding material on bobbin tubes to wound packages. The winding machine comprises two driven spindles. A traversing device holds a traversing guide. The traversing guide is driven for a traversing movement, whereas the traversing device is driven for a changing movement in a changing direction transverse to the traversing movement. A control device controls both the traversing movement and the changing movement. The movement of said traversing device and said traversing guide is controlled for guiding the winding material from a package wound at a first spindle via a fixed transfer device to the second spindle. The winding material is caught by a catching device associated with the second spindle. The winding material is cut by a cutting device wherein the cutting movement is caused by a rotation of the second spindle.

Abstract: A winding machine (1) for winding up sensitive bobbin material (8), for example yarn or tape, arriving from a feeding apparatus (11) includes a winding spindle (4) being designed and arranged to be rotated by a drive. A unit (14) of the machine (1) serves to determine a signal which is approximately proportional to the tension of the bobbin material (8). The unit (14) includes an arm (15) being designed and arranged to be movable to a limited extent and only one roller (16) being arranged at the arm (15). The only one roller (16) is designed and arranged to guide the bobbin material (8) to contact the feeding apparatus (11) and the roller (16) without contacting other elements in between. Especially, the winding machine (1) may include a plurality of winding heads (30) each including a winding spindle (4), a traversing apparatus (10) and a unit (14) for winding up bobbin material (8) arriving from a plurality of feeding apparatuses (11).

Abstract: A winding machine (1) includes a yarn traversing apparatus (2) including a housing (3) having an elongated opening (11). A reversing screw thread shaft (5) has an outer surface (14), it is rotatably supported in the housing (3) and it includes an endless screw thread groove (4). A traversing yarn guide (6) includes a body (7), a shuttle (8) being designed and arranged to engage the endless screw thread groove (4), a yarn guide (9) and a guide bush (12) having an inner surface (13). The traversing yarn guide (6) is designed and arranged to be driven by the reversing screw thread shaft (4) to reciprocate in an axial direction. The yarn guide (9) is designed and arranged to project out of the elongated opening (11) of the housing (3). The inner surface (13) of the guide bush (12) is designed and arranged to at least partially surround the outer surface (14) of the reversing screw thread shaft (5).

Abstract: An apparatus for manipulating a bobbin, in particular flanged bobbin at a winding machine, which includes a doffing carriage with lifting devices to raise and lower a bobbin between a winding height, at which the bobbin can be pushed onto or pulled off a chuck of the winding machine, and a transport height, at which the bobbin can be rolled while resting on a floor or on a conveyor belt running in front of the winding machine. Guide mechanisms are provided for the low-friction guidance of the doffing carriage with or without raised bobbin in a transport direction parallel to the chuck, between a winding position for winding the bobbin and a transport position in which the bobbin is transported to or away from the machine.

Abstract: A material winding and cutting machine is capable of automatically winding and cutting specified lengths of a material formed on a removable workpiece. Winding spindles (10 and 11) are rotatably mounted to drum (4) and revolve with the rotation of the drum between a winding station and a doffing station. Tubes (20) and fixed to the spindles (10 and 11) to receive the material (13). The machine includes a brake (27) which stops rotation of the material (13) about a winding spindle (10) during the cutting operation. The brake assembly stops the winding spindle to provide for an accurate cutting of the material to a predetermined length. Since the material does not rotate about the winding spindle during the cutting operation, the winding spindle incorporates a force storage device (28) to provide the needed tension to the material for proper cutting.
