Abstract: The invention relates to an installation method for setting up a control unit in a conveying device, wherein a first control unit controls an upstream first conveyor segment and a second control unit controls a downstream second conveyor segment. The method according to the invention comprises the steps of: placing an object on a first conveyor segment; activating a learning mode in a first and second control unit; activating a first and second conveyor drive by means of the respective first and second control unit; automatically conveying the object in the direction of the second conveyor segment; and storing an installation parameter in the second control unit depending on the triggering of the first or second sensor signal.

Abstract: The invention relates to a conveying device for conveying objects comprising a plurality of conveyor segments, each conveyor segment having a control unit for controlling the conveyor drive, and a bus communication, wherein each control unit is connected to the bus communication. Each control unit has a microprocessor for processing control signals, a first electronic memory connected to the microprocessor, in which a first control configuration is stored, and a second electronic memory in which a second control configuration is stored. The microprocessor is adapted to control the conveyor drive in a first operating mode with the control configuration stored in the first memory, to load the second control configuration from the second memory into the first memory when a configuration change command is received, and to control the conveyor drive in a first operating mode with the control configuration stored in the first memory.

Abstract: A method and device for producing cross-wound textile bobbins using a creel for holding a cross-wound bobbin, a bobbin drive roller operated by a single drive to rotate the bobbin and a thread traversing mechanism driven by a single motor. At a predetermined bobbin diameter or a predetermined thread length, a thread guide of the traversing mechanism is positioned to adjust a thread end reserve for an adjustable time span. While the thread end reserve (10) is being produced, a thread storage suction nozzle (60) particular to the winding head acts on the thread (7) running onto the bobbin (8) to intermediately store excess thread length being produced during the winding of the thread end reserve (10) and to insure a minimum thread tension to reliably fix the thread end reserve (10) on the bobbin body or the cross-wound bobbin tube.

Abstract: Yarn impurities are detectable by a method and device wherein a first diameterdependent signal is obtained in a first measurement of a linearly traveling yarn, the intensity of the light for a second measurement is set as a function of the first signal to compensate for the effect of the yarn diameter on the light reflected by the yarn and then the second electrical signal can be directly evaluated for detecting yarn impurities. The invention improves the detection of impurities, for example in connection with spinning and bobbin winding machines.

Abstract: A method and device for detecting foreign bodies in longitudinally traveling yarn (1), wherein light is directed on the yarn (1) and is reflected by its surface. Light reflected by the yarn (1) is detected by a sensor and is converted into signals. Subsequently, an evaluation of the signals is performed by comparing the signals with predetermined criteria which distinguish typical properties of foreign matter classified as tolerable, such as shell particles, from other foreign matter, such as foreign fibers, which are classified as not tolerable. Depending on whether these criteria are met, a decision is made whether a yarn interruption is suppressed or performed. In this manner, the efficiency of the production process of textile machines, such as spinning or bobbin winding machines, can be improved, and the uniformity and stability of the yarn are increased.

Abstract: A drag mechanism in a fishing reel consists of a plurality of washers. Some of the washers are metal while others are made of a high friction co-efficient material and are keyed to the main drive gear in the reel by means of a plurality of ears extending from the periphery thereof. This can be applied to conventional and spinning reels. By rearranging the position of the metal washers and high friction washers, the drag can be varied.

Abstract: A method for the contactless measuring of strand-like yarn material as well as to a device for carrying out the method. Textile material 4is irradiated within a measuring range of at least one ray source 1 and imaged on a sensor range of a receiving device 10 comprising sensor cells 8, 11, 12, 14. The signals generated by the individual sensor cells 8, 11, 12, 14 are converted into measured values for the dimensions of material to be measured 4. The signals of the sensor cells 12, 14 covered only partially by the image of the textile material 4 are taken into account in the measured result in a pro rata manner proportional to the amount of the covering.

Abstract: An apparatus detects foreign substances in strand-like textile material, such as slivers or yarn, using a white-light LED. The color detection is effected over more than two color support points whereby the detection of foreign substances in the textile material is improved. The apparatus is preferably operated in combination with a yarn cleaner in spinning or bobbin winding machines.

Abstract: A drag system for a fishing reel provides thermal expansion of the spool by having an outboard bearing which does not direct any force against the proximate shoulder of the spool.

Abstract: A textile machine includes a cheese or cross-wound bobbin winder with winding stations each having a creel for holding a cheese, a reversible rotary cheese drive, a suction nozzle and a swivel drive for swivelling the suction nozzle to the jacket surface of the cheese. A method for grasping a yarn end resting on the cheese includes adjusting a search time during which the inward-swivelled suction nozzle is positioned at the reverse-rotating cheese, in dependence on the instantaneous diameter of the cheese, and on the reverse speed of the rotary cheese drive, which is kept constant over the entire search time.

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.
