Abstract: The invention relates to a tank for washing a warp thread, provided with a device for intensifying the washing effect set in rotation inside the tank. Each device includes a body having cylindrical geometry, having circular cross section, which has a plurality of longitudinal bars arranged along the cylindrical side surface of the device. Between each pair of adjacent bars a longitudinal slit is defined. The body also has a pair of end elements extending radially, forming the opposite bases of the body and configured to support and enclose the bars. The body also has a pair of opposite rotation pins, obtained on the respective outer surfaces of the end elements and that extend along an axial direction and parallel to the direction of extension of the bars. The body also has a tangential turbodynamic flow generator, arranged inside the body and configured to intensify the interchange between the washing liquid and the warp thread through the longitudinal slits during the rotation of the device.

Abstract: With a method of operating a photoelectric sensor a pulsed light beam is sent by an emitter, received by a receiver spaced from the emitter, and converted into a received signal. Measurement values of the received signal are recorded by an evaluation device with the method. The recording of the measurement values is synchronized with the received signal by the evaluation device. Event times of positive and/or negative flanks of pulses of the received signal are identified by a flank detector of the evaluation device here. A controller of the evaluation device to which the event times are sent determines a subsequent event time after an event time if this lies within a time interval around an expected subsequent event time. Synchronisation is carried out of at least two successive event times have been identified. Measurement times are determined from the event times for recording the measurement values.

Abstract: Knitted fabric and method of forming knitted fabric. Knitted fabric includes warp threads that run in a longitudinal direction and that are connected to one another by a stitch formation, and at least three sections arranged consecutively in the longitudinal direction. The at least three sections may include at least one section formed as a spacer fabric, one section formed as a single-ply fabric and one section formed as a tubular fabric.

Abstract: Method and apparatus for producing a scrim. The method includes depositing several band sections next to one another on a conveyor device that at least temporarily moves in a direction of transport. The direction of transport is oriented at a predetermined angle to a band direction and each band section has a front edge running in the band direction and a rear edge running in the band direction. The method also includes placing the band sections so that the rear edge of a first band section is adjacent the front edge of a second band section, calculating a rear-edge shape of the first band section and a front-edge shape of the second band section and placing the second band section on the conveyor device relative to the first band section as a function of a relation between the front-edge shape and the rear-edge shape.
