The damping device (29) has a movable, electrically conductive component (30), which is at least indirectly connected with the creel (18) and is arranged such that the movably seated component (30) intersects the magnetic field of a stationarily arranged magnet system (32), preferably a permanent magnet system, in a contactless manner.

Abstract: A device for controlling a creel (12) of a textile machine, which is supported to be pivotable to a limited degree by a pivot shaft (14) via a defined torque generated by a torque generator (24, 28, 30) controlled by a drive mechanism (34). The torque generator (24, 28, 30) is connected with the creel (12) by means of a reduction gear arrangement (20, 22; 60, 62).

Abstract: A thread guide (33) for traversing and guiding a thread (5) in a rotating winding bobbin (1) for producing a cross-wound bobbin in a bobbin winder of a textile machine by controlling vibrations of the thread guide. The thread guide (33) is permanently and directly connected to at least one energy accumulator (20,21) throughout the entire traversing motion. The potential energy of the energy accumulator (20,21) increases continuously after the dead center of the traversing area. A substantially harmonious oscillating mechanical system is thus formed with the thread guide.

Abstract: A bearing housing (23) for a drive device (27) integrated in a creel (18) of a cheese-producing textile machine, which brakes the cheese (11) via a braking current directed opposite the nominal rated current of the drive device.

Abstract: A method for producing cheeses of the random winding type, wherein the workstations of an automatic cheese winder comprise a winding device with a yarn guide drum and a creel, both supported in an axially shiftable relation to each other, the creel holding the cheese in a rotatable manner and the yarn guide drum driving the cheese through frictional engagement, a ribbon disturbance device and an edge displacement device. The ribbon disturbance device causes a slippage by a defined adjustment of the bearing pressure of the cheese on the yarn guide drum. Relative movements between the yarn guide drum and the creel are initiated in the area of ribbon winding zones which counteract a stroke change caused by the ribbon disturbance during the winding of the yarn onto the cheese.

A coolant circuit (36) is arranged inside the creel (18) for removal of the motor heat of the electromotor (35) of the drive device (27).

Abstract: A winding device (24) for a textile machine (1) producing cheeses has a creel (18) for holding a cheese (11) between tube receiving plates (38, 38′), a yarn traversing device (28) comprising a separate drive (31), and a speed-regulatable drive device (27) integrated in the creel (18) to move in a bearing housing (23) of the creel (18) and connected to one of the tube receiving plates (38, 38′). The drive device (27) can be loaded with a braking current which produces a moment opposite the direction of rotation (SR) of the cheese (11), for braking the cheese (11). The drive device (27) is arranged in a sliding sleeve (35) that can be loaded pneumatically against the displacement force of spring elements (43) to move one of the tube receiving plates (38) outwardly as needed in a creel opening direction.

Abstract: An apparatus for controlling the tension of a traveling yarn includes a rake tensioner having stationary and displaceable yarn tensioning elements in engagement with the traveling yarn, and an electrical coil to which electrical current is supplied by a regulating device. The displaceable yam tensioning elements and the electrical coil are disposed on a common pivot lever. The electrical coil is pivotable in an air gap through which magnetic field lines pass. The tension of the traveling yarn is controlled as a function of the current supplied to the electrical coil. The present invention, thusly, improves the control of the tension of the traveling yarn in spinning or bobbin winding machines.

Abstract: A device for pivoting a creel of a textile machine, which holds a bobbin in contact with a roller during the winding process. The creel (2) is fastened on a shaft (5) defining a pivot axis. A lifting device (9) connected with the creel (2) has a lever (10) fixed with the shaft (5) against relative rotation. An arresting element (12) seated on the shaft (5) can be alternatingly coupled to the shaft (5) or a fixed holding element (21). When the arresting element (12) is coupled with the shaft (5), potential energy is stored in an energy storage device, which is released when the connection changes from the shaft (5) to the holding element (21), whereby the lever (10) and the shaft (5) are abruptly moved toward the arresting element (12). The device makes it possible to break the contact between the cheese (1) and the drive roller (3) quickly and dependably in case of a power failure. Interference with grasping an upper yarn end, as well as damage to the yarn and yarn positioning errors, can be avoided.

Abstract: A tensile yarn force sensor (7) has a measuring member (17), with which the tensile force of a traveling yarn (1) is detected as a function of the measurable pressure the yarn (1) exerts on the measuring member (17) during winding onto a cheese (2) at the work station of a multi-station textile machine, e.g., a winding machine or a combined spinning/winding machine. At preselectable intervals, a control device (11) actuates cutting of the traveling yarn (1), and triggers the performance of a zero compensation at the measuring member (17) thereby relieved of the yarn pressure, whereby external influences on the measured result are sufficiently compensated by the zero compensation, even if the chronological sequence of bobbin changes, yarn breaks or cleaning cuts triggered by imperfections in the yarn alone do not offer a sufficient opportunity for performing the required zero compensations.

Abstract: A yarn guide imparts a traversing motion to a yarn being delivered to a rotationally driven takeup bobbin in a textile yarn winding operation to create a cross-wound bobbin, or cheese. The yarn guide includes a fork-like yarn guide pivoted about a pivot axis substantially perpendicular to the axis of the takeup bobbin, and an electromagnetic mechanism for driving the guide. The electromagnetic mechanism includes an air gap, a plurality of magnets disposed along the air gap, a plurality of yokes and at least one electrical coil extending into and moveable along the air gap with the traversing yarn guide. The magnets are disposed along the air gap and generate magnetic field lines which extend in a substantially perpendicular direction through the air gap.

Each manipulating and transporting arrangement (3) has a horizontally arranged transport unit (5), and an essentially vertically arranged transport unit (6). Transport elements (9′, 9″) for receiving delivery bobbins (4, 4′, etc.) are arranged on the transport units (5, 6) in a definitively shiftable manner for transfer between one transport unit (5) and the other transport unit (6).
