  • Publication number: 20120009838
    Abstract: Disclosed are a hand-tearable adhesive tape which is made of a sheet woven with warps and wefts, in which the warps have a smaller titer than the wefts, and is coated with a flame retardant to provide flame retardancy and is with an adhesive agent, and a method for manufacturing the same. Advantageously, the hand-tearable adhesive tape can exhibit superior adhesive force, while providing flame retardancy and can be torn by hand.

  • Patent number: 5157818
    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 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.

  • Patent number: 5088441
    Abstract: The method of impregnating and the apparatus for impregnating a thin cord with a medicinal solution with the cord to be used in the dental field as an appliance for gingival retraction in conjunction with the teeth of a human being. The cord is immersed in a bath of the medicinal solution, moved from the bath to a squeezing roller assembly so that the medicinal solution evenly permeates the cord, removing excess solution, drying the cord and winding the cord on a wind-up reel prior to being dispensed to the consumer.

  • Patent number: 4858287
    Abstract: The method for the production of partial warps wound on warping beams or sectional beams, or warps of synthetic filament yarns wound on warp beams, which are completely stretched and sized, consists of sizing a group of parallel synthetic thermoplastic filament yarns, the filaments of which are not completely stretched, in a sizing zone, predrying the sized yarns in a heated predrying zone, subjecting the predried sized group of yarn by final drying in a heated final drying zone, and finally winding the dried group of yarns on warping or (sectional) beams, while the filaments of the filament yarns are stretched jointly and simultaneously in the predrying zone. The stretching occurs preferably between rolls (5, 6) assigned to the sizing zone and rolls (10) assigned to the final drying zone. The method may be carried out with conventional, at most slightly modified sizing machines and it furnishes very uniform partial warps or warps.

  • Patent number: 4571792
    Abstract: The ends of warp yarns in a sheet form are treated at the end of a sizing process in preparation for a subsequent rewinding process. In the sizing process, the warp yarns are threaded through a reed with at least two warp yarns in each reed dent in vertically spaced relation. The at least two warp yarns are threaded through one dent in a reed in the rewinding process. Heretofore, it has been tedious and time-consuming to thread the warp yarns through the reeds since the warp yarns in one reed dent cannot be distinguished from those in other reed dents in the sizing process. In the rewinding process, a spacer such as a rod is inserted between vertically divided sheets of the warp yarns to prevent snarling. Since the warp yarns cannot be distinguished from reed dent to reed dent, it has been difficult to insert the spacer.

  • Patent number: 4271570
    Abstract: Misaligned strands in a graphite fiber on tape are aligned and wound up on reels with a minimum of degradation by the steps of: separating the individual strands, diverging the strands, aligning the strands and winding the individual strands onto separate take-up reels in one continuous operation.Graphite fabric woven from the strands exhibit little or no degradation and have a uniform density and excellent physical properties. The alignment apparatus is inexpensive, simple to operate and occupies a relatively small space.

  • Patent number: 4236319
    Abstract: In a sizing process for a warp sheet of yarns, a drying chamber has an upper first region, substantially void of a drying medium, and a second region containing the drying medium. A transversable warp splitting device is provided in the chamber which is traversable from the first region, where a plurality of splitting bars can be inserted through the warp sheet so as to split it into sheets of lesser density, to a second region, where the warp sheet is acted upon by the drying medium.A cooling medium is provided between the first and second regions so as to prevent migration of the drying medium from the second region to the first region.The splitting device comprises a carriage driven for movement along a track which extends in a downwardly inclined direction from the first region to the second region.

  • Patent number: 4154005
    Abstract: A drier, comprising an enclosed casing, means for feeding a sheet of parallel yarns to be dried through the casing in at least one substantially horizontal pass, nozzle boxes disposed above and below the sheet material in each pass to form a drying chamber, means for introducing hot air into the nozzle boxes, and slots in the walls of the nozzle boxes which face the sheet, said slots constituting nozzles effective to discharge hot air from each nozzle box onto the opposed surfaces of the sheet at an angle to the vertical in the range of to and the slots in the upper and lower boxes being slanted in opposite directions to the direction transverse to the direction of travel of the sheet.
