A method at a workstation of a spinning machine or winding machine supplies an auxiliary thread from a thread nozzle to a suction assigned to the workstation, the auxiliary thread stretched between the thread nozzle and the suction. The auxiliary thread is severed to form a thread section protruding into the suction and a thread section extending into the thread nozzle, wherein the thread section protruding into the suction is carried away by the suction. The thread section extending into the thread nozzle is grasped with a thread receiver such that the thread section extending into the thread nozzle extends between the thread nozzle and the thread receiver. The thread section extending into the thread nozzle is severed to form a thread section remaining in the thread nozzle and a thread section coming from the thread receiver. The thread section coming from the thread receiver is transferred to the suction of the workstation. The thread section coming from the thread receiver is grasped with a capture arrangement adjacent a tube at the workstation prior to starting a process of winding the thread section coming from the thread receiver onto the tube.

A cooling system (100) for cooling a cable (10). The system (100) comprises: at least one fixed cooling channel (20), which is arranged downstream of an extrusion head (EH); and at least one multi-pass apparatus (30), which in turn comprises a set of fixed pulleys (32, 33, 34), and a fixed, motor-driven capstan (35) designed to wind the cable (10). The system (100) is characterized in that the multi-pass apparatus (30) comprises a movable pulley (36) designed to translate along vertical guides (39A, 39B). The movable pulley (36) and the vertical guides (39A, 39B) are contained in a cooling device (56) for cooling the cable (10).

An automated filament exchange method includes: locating the spool for winding the first filament for the 3D printer; winding the first filament on the subspace of the spool located at the spool location step; allowing the first filament wound at the subspace first filament winding step to pass through a gap formed on the main space flange located between the main space and the subspace; and winding the first filament located at the main space of the spool on the main space of the spool, wherein after the first filament is wound on the subspace of the spool, the first filament passes through the gap and is then wound multi-layeredly on the main space of the spool.

A method is provided for operating a work station of a spinning or winding machine, wherein the work station includes a spinning device for producing a thread or a cop for delivering a thread, and a winding device for producing a bobbin on a tub. The winding device includes a swivel-mounted bobbin holder with a bobbin plate for receiving the tube and for catching the thread, a powered winding roller for rotating the tube or a bobbin, and a thread traversing device. A first suction nozzle is directed towards a circumference of a bobbin on the bobbin holder, and a second suction nozzle is arranged on the bobbin plate turned away from the bobbin and spaced from and directed counter to the first suction nozzle. To attaching a thread to an empty tube placed on the bobbin holder, the thread is arranged in the first and second suction nozzles so that the thread is tensed by negative pressure at least in the second suction nozzle. Subsequently, the tensed thread is captured between the first and second suction nozzles with a catching device in order to catch the thread for subsequent winding onto the empty tube.

A method for operating a textile machine producing cross-wound packages has a multiplicity of autonomous work stations that each have a spinning apparatus and a winding apparatus and are equipped with a suction nozzle, connected to the vacuum network of the textile machine, for receiving a thread from the surface of a cross-wound package, and also a storage nozzle, likewise connected to the vacuum network, for temporarily storing excess thread length, and which is operated at least by one service unit that exchanges full cross-wound packages for empty tubes as required. The invention provides for the actuation of a cross-wound package/empty tube exchange by one of the service units to be prevented during the operations of restarting of the work stations, thereby ensuring that, during the restarting of the autonomous work stations, the maximum number of work stations always starts up again at the same time.

A wire body winding device includes a rotating plate that rotates together with a drive shaft, a bobbin that is attached to the rotating plate and winds a wire body, and a locking portion that is attached to the rotating plate and locks the wire body. The locking portion includes a base member fixed to the rotating plate and a guide member disposed so as to overlap the base member. The locking portion has a base end portion at which the guide member is fixed to the base member and a tip end portion configured to receive the wire body. The locking portion has a shape in which a distance between the base member and the guide member increases gradually from the base end portion toward the tip end portion.

A winding device for winding a material to be wound includes a winding mandrel provided for carrying a carrier of material to be wound in a winding process, with a transporting unit on which at least a component of the winding mandrel is arranged, and with a positioning unit provided for changing a spatial position of the transporting unit. The positioning unit is provided for at least substantially adjusting a spatial end position according to requirement. The transporting unit is embodied as a pivot arm, the transporting unit is in at least one operating state provided for receiving a carrier of material to be wound, wherein the material to be wound is wound onto the carrier of material to be wound and/or is wound off the carrier of material to be wound, and the transporting unit is in the winding operative position during the winding process.
