Abstract: The yarn tension is modulated by a yarn-braking device controlled by a control unit which receives signals of measured tension from a tension sensor and compares them with a reference tension signal in a control loop; as long as the reference tension remains unchanged, a first set of coefficients is used in the control loop causing the control loop to have a relatively slow behaviour in relation to the error-compensating action; when a change in the reference tension occurs, the system switches to a second set of coefficients causing the control loop to have a relatively fast behaviour; the second set of coefficients is maintained as long as the difference between the second value of the reference tension and the measured tension remains greater or equal to a predetermined minimum value, then the system switches again to the first set of coefficients.

Abstract: A filament winding apparatus that prevents excessive unraveling of a fiber bundle due to variations in the speed at which the fiber bundle is wound includes a hoop winding device having a wrapping table, a bobbin support unit, a braking unit, a slack removal unit, a detector, and a controller. The slack removal unit absorbs slack caused by the difference between winding and unraveling speeds of the fiber bundle. The detector detects whether the amount of slack absorbed is equal to or greater than or is less than, a predetermined amount. When the amount of slack is equal to or greater than the predetermined amount, the controller increases the braking force of the braking unit for braking rotation of a bobbin. When the amount of slack is less than the predetermined amount, the controller reduces the braking force of the braking unit for braking rotation of the bobbin.

Abstract: The invention relates to a winding machine. Winding material is continuously fed along feeding paths to two wound packages. A control signal is generated for actuating actuators. The actuators change the pressing force pressing a pressure roller at at least one wound package. The control signal depends on a tension of the winding material. In case that the tension of the winding material in a path to a wound package exceeds a predetermined tension the pressing force of the pressure roller at the associated wound package is increased. Accordingly the radius of the outer surface of the associated wound package is reduced. This reduction is intended for counteracting the undesired increase of the tension in the winding material.

It achieves the object of designing a method of this type in such a way that with this method small sheets can be produced as exactly as possible in predetermined sizes. To do this, the active-ingredient film (2) is pulled off automatically, is separated from a substrate material which, if present, and in tensioned form, is fed to a cutting station and is cut, in the feed direction, into long, narrow strips (7) of predeterminable width, and the long strips (7) are brought together in the feed direction and together are fed by a further feed device (10) to a transverse cutter (11), which cuts through the combined long strips (7) at predetermined intervals.

Abstract: The invention concerns a creel (2) comprising a plurality of winding heads (7) from which several yarns of the same type or of different types are drawn simultaneously by means of a winding machine (3). Said creel comprises at least one dynamic yarn tension device (6) which is associated with each winding head and at which a variable braking force is applied to the yarn to produce a predetermined yarn tension. Each yarn tension device (6) can be activated by means of an associated drive motor (20). Said creel (2) comprises a control device for controlling the yarn tension based on the angular speed or the yarn speed during a start-up and/or an interruption of the winding machine (3), as well as a regulator (25) for regulating the yarn tension during the normal stationary phase of the winding machine (3).

Abstract: The yarn feeder device (1) of the invention has one or more yarn feeler levers (26), which are movably supported on the housing (2). The yarn feeler lever (26) is movable between an operating position I and a response position II. In the operating I, its crossbar (28) which forms the yarn feeler means is approximately in the same line as yarn guide elements, such as the struts (19, 23) of yarn guide bails (18, 22). Somewhat above its operating position I, the yarn feeler lever (26) meets a stop, past which it is not moved by the yarn (8). To improve the accessibility to the yarn guide elements (19, 23) particularly when yarn is being inserted and threaded in, the stop of the yarn feeler lever (26) is embodied as yielding. The yarn feeler lever (26) can therefore be moved upward manually past the stop on its lower end (28), in order to open up the space enclosed between the yarn guide elements (19, 23).

The charger charges the material web, which is thereby drawn to the braking plate, lies on the braking plate, and is braked via friction. It is advantageous that the charge voltage of the charger and be controlled via sensors for the web tension and web position and can very quickly react to the signals of the sensors.

Abstract: A traveling yarn tension compensating system having a pair of vertically disposed, horizontally spaced ball-type yarn tensioning units and a yarn tension compensating device disposed therebetween. The device has a yarn engaging element with a yarn engaging surface that is downwardly convex for engaging a yarn thereunder. The surface is fixed so as not to rotate or otherwise move in the direction of travel of the yarn and is made of a material that imposes a tension increasing frictional drag on the traveling yarn. The surface engaging element is mounted to be freely movable vertically in response to tension in the traveling yarn. The convex shape of the yarn engaging surface results in a greater extent of surface engagement of the yarn when the surface engaging element is in a lower position resulting from lesser tension in the yarn and at which position it deflects the yarn downwardly over the yarn guides.

Abstract: A wire tensioning device for maintaining tension on a moving wire, especially a wire that is uncoiled over the axial end of a fixed spool of wire. The tensioning device includes a disk mounted at an axial end of a spool of wire. The disk has a plurality of radially extending resistant filaments that protrude beyond the periphery of the axial end of the spool of wire. The filaments engage the wire as it is unwound from the spool over the axial end thereof to apply a resistance to the uncoiling of the wire. A drive shaft powered by a reversible electric motor connects to the disk which motor rapidly responds to changes in resistance applied to the uncoiling wire by the bending or unbending of the filaments. An arm is engaged by the uncoiling wire. The arm is connected to a rotatably mounted axle for movement in a limited arc. A rotor is formed on the axle with the rotor having a lobe. A pair of proximity switches for operating the reversible electric motor in opposite directions of rotation are provided.

Abstract: A method for operating a work station (10) of a cheese-making textile machine. A work station computer (32) communicates with a tensile yarn force sensor (54) for monitoring the tensile yarn force of a yarn (22) traveling from a supply bobbin (12) to a takeup bobbin (14).
