Abstract: A slasher includes a moistening unit for moistening warp yarns by spraying water on the warp yarns, a squeezing unit for squeezing the moistened warp of the warp yarns, and a sizing unit for sizing the moistened and squeezed warp yarns. The moistening unit sprinkles water on the warp yarns to moisten the warp yarns. The warp yarns absorb part or all of the water sprinkled thereon. The warp yarns are not immersed in water during moistening to avoid excessive moistening. The squeezing unit squeezes the moistened warp yarns so that moisture infiltrates the warp yarns and the warp yarns is moistened uniformly. The moisture moistening the warp yarns is replaced and mixed with size liquor while the warp yarns are being passed through size liquor, so that the warp yarns can be easily and uniformly sized.

Abstract: A device for measuring running distance of a yarn, which detects an abnormality in yarn moving along a path of travel past a means for detecting the abnormality. The measuring device is capable of generating a stop signal in response to detecting the abnormality and measures the distance travelled following the generation of the stop signal. The location of the abnormality is indicated by various means including a plurality of lamps and numerics display. Further, the device can stop the abnormality at a predetermined distance.

Abstract: A sizing machine capable of maintaining a sizing liquid at a desired temperature by controlling the supply of steam into a cavity box containing the sizing liquid is provided with a sizing liquid consumption measuring system capable of accurately measuring a sizing liquid consumption. The sizing liquid consumption measuring system measures a sizing liquid consumption automatically by measuring the quantity of water added to the sizing liquid contained in the cavity box by steam supplied into the cavity box, and the level of the sizing liquid in the cavity box.

Abstract: A controller for a winding machine, for controlling the tension of a work running from a feed roller to a winding beam. The controller comprises a speed ratio control unit having a high response speed to control exactly the respective rotating speeds of a feed motor for driving the feed roller, and a winding motor for driving the winding beam during the decelerating operation of the winding machine to maintain the work at a tension substantially the same as a predetermined tension for stationary operation during the decelerating operation of the winding machine. The controller reduces time necessary for stopping the winding machine to the least extent.

Abstract: A size viscosity controller for a slasher, for controlling the viscosity of the size circulated within the sizing vat of the slasher. The viscosity of the size is maintained at a desired viscosity by controlling heat supply units on the basis of the deviation of the measured temperature of the size from a desired temperature so that the size is maintained at the desired temperature and, at the same time, regulating the concentration of the size by supplying wet heat, such as steam or hot water, to the size or heating the size by dry heat, such as heat generated by an electric heater, to regulated the concentration of the size.
