Abstract: A creel loading and relieving device for a winding device of a textile machine producing crosswound bobbins adjusts the contact pressure of a take-up bobbin mounted in a creel on a driving roll. The creel loading and relieving device comprises a creel pivotally mounted via a creel shaft and a force applying means which grips the creel and is adjustable via a positioning element. The creel loading and relieving device (30) has an actuator (33) that can be positioned by an electromotive drive (40) while a force applying means (29) which impinges upon the creel (9) is disposed on said actuator (33). The force applying means is configured as a pneumatic spring (29) and is hinged to a first lever arm (25) connected to a creel yoke (24). The loading or relieving moment applied to the creel (9) by the pneumatic spring (29) can be adjusted with precision by positioning the actuator (33).

Abstract: A device for winding conical cross-wound bobbins has a creel pivotably mounted about a pivot axis and receiving the conical bobbin, a yarn guide traversing alongside the creel, and a yarn accumulator adapted to accumulate and pay-out a stored length of yarn. The prevailing instantaneous driven diameter (da) of the cross-wound bobbin (24) is detected by a first sensor device (48, 48′), the prevailing instantaneous position and/or the direction of travel of the yarn guide (36) is detected by a second sensor device (50, 50′), and the sensor devices (48, 48′, 50, 50′) are connected to a control device (46) which supplies a control signal for a drive (40) of the yarn accumulator (32) as a function of the signals supplied.

Abstract: In textile machines that produce cross-wound bobbins, especially open-end spinning machines, the yarn is laid onto the cross-wound bobbins with yarn guides. The yarn guides are commonly reciprocated with a driven traversing rod. All the yarn guides of the work stations located next to one another are driven simultaneously by this traversing rod. For the sake of uniform laying of the yarn and so that the traversing rod will not sag under tensile and compressive strain, careful rectilinear guidance of the traversing rod is required. Four successive support rollers each are angularly distributed about the circumference of the traversing rod in such a way that, viewed in the circumferential direction of the traversing rod, mutually identical wheel flanges are always adjacent to one another. Those support rollers which are adjacent with respect to the circumference of the traversing rod and whose wheel flanges are toward one another each have the same angular spacing relative to the other two support rollers.

Abstract: The invention to a yarn tension sensor, in particular for yarns traveling at high speed, to accurately ascertain even short-term yarn tension fluctuations. According to the invention, a yarn guide element is mounted on one head end of a plunger coil disposed in a magnetic field. A position sensor is disposed in the region of the plunger coil and detects even minimal changes in position of the plunger coil. These changes in position are reported to a controller, at whose output variations in current are generated and supplied to the winding of the plunger coil, the variations being such to compensate for the axial force generated by the yarn and acting upon the plunger coil, thereby making the plunger coil virtually motionless.

Abstract: The present invention relates to a brake disk arrangement for a yarn tensioning device wherein at least one of a pair of opposed facing brake disks can be acted upon by a variable pressing force in the direction of the other brake disk. According to the present invention, rotary motion is transmitted from one brake disk to the other in a simple manner, without affecting the brake force, by connecting to one of the brake disks a concentric magnet that is secured against relative rotation with respect to this brake disk, and by connecting to the other brake disk a concentrically arranged body of hysteresis material which is secured against relative rotation with that brake disk. At least the brake disk that can be acted upon the variable pressing force comprises a nonmagnetic material and is changeable in position axially relative to the magnet or the hysteresis material associated with the disk. In alternate embodiments, both brake disks may be provided with a magnet.

Abstract: A method and apparatus for restoring the normal winding of yarn following a yarn break during a textile winding process is provided. A lower yarn end engaging member executes a predetermined number of attempts to engage a lower yarn end and a package exchange member exchanges a supply package for a fresh supply package in response to the detection of the absence of engagement of a lower yarn end after the predetermined number of lower yarn end engaging cycles.

If engagement of an upper yarn end is detected after a predetermined number of attempts, the lower yarn end and the upper yarn end are joined together and normal winding is resumed. If an upper yarn end is not detected after a predetermined number of attempts, a problem indicating member is activated to indicate to an operator that normal winding of yarn cannot be restored.
