Abstract: A method and apparatus for applying sizing S to warp yarns W for weaving is disclosed. The method includes applying a concentrated solution having at least twenty percent solids and possibly up to eighty percent by applying the solution to the warps at the nip 22 of a pair of pressure rolls 12 and 14 where the bottom roll 14 is partially immersed in a slasher box and excess size solution is removed by means of a doctor blade 30. The warp yarns W are delivered directly to the nip. The doctor blade 30 is located downstream of nip 22 between the rollers such that there is no rollback of size at the nip and a desired add-on weight of size S is pressed into the yarns W. In a preferred embodiment, the application roller 14 has a relieved pattern surface 40 and the doctor blade 30 wipes the raised portions thereof leaving a metered amount in the relieved areas of the roll for application to the warps. Solution removed by the doctor blade rolls back to the slasher box.

Abstract: An apparatus for producing interlaced multifilament yarn having an improved configuration is disclosed. When a material yarn is treated by an interlacing apparatus provided with an interlacing nozzle wherein a hollow longitudinal space is formed therein and a jetted fluid is introduced into the hollow longitudinal space, the jet fluid is directed to an axis of the passage of a running yarn in the longitudinal space along a direction substantially perpendicular to the axis of the yarn passage in such a condition that the jet fluid is diffused to a direction along the yarn passage. Accordingly, the individual filaments of the running yarn are vibrated about the axis of the running yarn passage, mainly along a plane defined by the axis of the yarn passage and the axis of a fluid conduit for supplying the jet fluid. According to such effective vibration of the individual filaments, a very stable interlaced configuration of the individual filaments can be created.
