Abstract: In sizing and drawing of one or more textile filaments, particularly a warp sheet of multiple filaments, by successively conveying the filaments through a sizing bath, a driven squeezing mechanism, a differentially driven spaced drying roller, and a warp beam or other filament winding mechanism, the filaments are heated to a temperature of approximately 100.degree. C. and maintained in a predetermined moistened condition, e.g., by the application of saturated airborne water vapor, within the draw zone between the squeezing mechanism and the drying roller, in order to achieve a sufficiently elevated temperature for draw stretching of polyester filaments, particular POY and LOY filament, without premature drying and undesirable cracking of the sizing applied to the filaments.

Abstract: A web drying apparatus is provided for a textile machine of the type which is operable to apply a coating or otherwise to wet a web of textile material which is continuously traveled therethrough. The web drying apparatus includes at least a pair of groups of cylindrical drying rollers with each group of rollers being disposed on a respective side of a reference plane. The reference plane is inclined upwardly relative to a nip formed by a pair of squeezing rollers of the wetting device which applies the coating or otherwise wets the textile material. In one embodiment, the drying rollers of one group are disposed in a horizontal plane and the drying rollers of the other group are disposed in a vertical plane. The web drying apparatus additionally includes a device for separating a wet textile web into multiple separate webs.

Abstract: An emerizing apparatus is equipped with an emergy roller having multiple beater blades about its circumference, the outer periphery of each beater blade being formed with a pair of axially extending longitudinal beater edges and a concave arcuate recess therebetween, whereby each beater edge is adapted to individually strike a textile web traveling in tensioned engagement with the roller periphery to produce a shorter and more dense napped surface on the textile web than can be achieved by a corresponding conventional emery roller operating at the same rotational speed.

Abstract: Yarn sheet tension in a warp beaming operation is controlled by supplying a primary analog correcting signal to the drive of the warp beam based upon ultrasonic measurement of the progressively increasing effective beam diameter and by adding a supplementary proportional-plus-integral-plus-derivative (PID) correcting signal thereto based upon detected movements of a movable dancer roll biased into peripheral engagement with the yarn sheet as it is delivered to the warp beam.

Abstract: Method for applying a liquefiable material in form of a foam or a high-viscosity solution from a storage container onto a substrate which is conveyed in form of a web, with the aid of an application device which is provided with at least one discharge opening which is oriented in a line transversely to the direction the web is moving. A stream of the liquefiable material is introduced at one end of the application device. This stream is metered and the quantity passing through per time unit is measured. Part of the stream of liquefiable material is discharged at the other end of the application device and conducted back to the storage container, and also the flow-through quantity per time unit is measured. The difference of the measured quantities passed through per time unit is compared to a nominal value. The parts of the stream are dosed such that the difference of the measured quantities passing through per time unit approaches the nominal value.

Abstract: A method of operating a finishing machine includes impregnating all of the threads of an undivided warp formed of individual threads at full thread density with liquid sizing. All of the threads of the undivided warp are directly sprayed at full thread density with a post-treatment separating agent while the sizing is still in the liquid state. The individual threads of the warp are subsequently dried in an undivided manner at full thread density.
