  • Patent number: 11047079
    Abstract: The needle loom for needling a nonwoven web comprises a needle beam arrangement, which comprises at least one needle beam, and a drive device for moving the needle beam arrangement back and forth in a punching direction. The drive device comprises a drive and two main shafts, on each of which a main conrod is eccentrically supported. The main conrods connect the main shafts to the needle beam arrangement in articulated fashion. The main shafts are driven rotationally in opposite directions. The drive device comprises an endless traveling transmission element, which couples the main shafts to each other. The transmission element also passes around first and second adjusting rollers. An adjusting device is provided for a translational adjustment of the position of the first and second adjusting rollers. This translational adjustment brings about a rotational adjustment of the phasing of the main shafts with respect to each other.

  • Patent number: 10920350
    Abstract: A felting needle has a working part that extends lengthwise along a part of the longitudinal extent thereof. The needle has a cross-sectional area which extends in the radial and circumferential directions of the felting needle and forms the cross-sectional area of the working part for much of the length thereof and at least one barb which penetrates into the working part which is formed by an incut running from the outer surface of the working part towards the interior of the needle. The needle includes at least one bulge which projects beyond the circumferential surface of the felting needle in the working part thereof. The bulge extends lengthwise only along a part of the working part and has volume constituents that do not belong to the barbing bead of the barb. The barb adjoins the outer surface of the bulge lengthwise along the felting needle.

    Abstract: A crosslapper receives a card web and folds it into a lap intended to be needle-punched or consolidated by other means. The web comprises zones which are more condensed, having a spectrum of orientation of fibres with a component parallel to the width of the web, alternating with less condensed zones having a longitudinal unidirectional spectrum of orientations. The zones which are less condensed are used to form the edge zones of the lap. The result is that the lap has different respective spectra of orientation which pre-compensate for the unwanted changes produced by the needle-punching or other consolidation which follows. A needle-punched lap is obtained having a uniform MD/CD ratio (relationship between longitudinal and respectively transverse tensile strengths) or having a sought profile of the MD/CD ratio across the width of the lap.

  • Patent number: 7246418
    Abstract: The felting needle according to the invention comprises a working part (12) with two partial sections (15, 16), each of which is preferably embodied with straight edges. The two partial sections are twisted slightly, relative to each other. Each partial section is provided with at least one ring of indentations with the indentations arranged offset to each other in axial direction. As a result, all notches are oriented uniformly in the direction of the longitudinal axis (14), despite the slight twisting of the section between the two partial sections (15, 16). The felting needle can thus be used to produce fleece materials and needle-punched felt materials, which have a nearly uniform tearing resistance in longitudinal as well as lateral direction.

  • Patent number: 7117571
    Abstract: A system and method for reinforcing a textile web of a fiber web or a fiber fleece by needling in a plurality of directly successive steps are provided, in which the web is needed from both sides with a high needle density in an alternating manner and in the state of the needles stitched into the web is transported through a movement of the needles which extends in the longitudinal direction of the web, where each needle in a stitching-in movement grasps merely a single fiber, having a gauge of 1 to 2 dtex, from the web. By the aid of the invention very thin fleeces can be produced without damaging same during their processing.

  • Patent number: 7114226
    Abstract: A needle (1) according to the invention serves for the after-treatment, particularly after-needling of flat textile products, particularly for roughening of the product surface. The needle (1) is of fully symmetrical construction with respect to the central longitudinal axis (11); this applies particularly also to its barbs. The needle gauge is at least 46 and the barb depth is 0.02 mm at the most. The needle ensures a gentle, protective operation and the making of particularly fine textiles.

  • Patent number: 6973807
    Abstract: A stitch needle (10) is provided with a tip (29) which is shaped as a center punch and has no recognizable rounding at its terminus (31). The tip (29) is preferably arranged at mid height of the hook-shaped aperture (36) which is structured for capturing the yarn (13). The particular shape of the tip (29) and its positioning minimize the wear of the stitch needle (10) and also minimize damages to the yarn (13).

  • Patent number: 6839945
    Abstract: The invention relates to a method for preparing a moisture barrier fabric comprising needing the fabric in a direction substantially opposite to the advance direction of the fabric with barbed needles to increase the density of the fabric by entangling the fibers thereof, open-width washing of the needled facecloth fabric with a detergent and sodium carbonate to further increase fabric density by allowing the fabric to neck down or bulk at a substantially random rate, coating one side of the fabric with at least one coating of a latex formulation for use in forming the backcoating of the moisture barrier fabric, comprising a (meth)acrylic acid urethane copolymer having a curing temperature of approximately 250 to 275° F., and immersing the dry moisture barrier fabric, including the latex backing, into a bath of fluorochemical and solution containing about 10 to about 15 wt % polyurethane, and removing excess fluorochemical from the treated fabric.

  • Patent number: 6735836
    Abstract: A needling loom comprising needles actuated in reciprocating motion between a retracted position and a maximum penetration position through a stripping plate, a textile web to be consolidated, and a needling loom table. The stripping plate and the needling loom table bear rails and elements for rapid assembling and disassembling for either pressing the rails against fixed crosspieces for the needling loom to operate, or for releasing the pressure and cause the rails to rest on rollers for extracting and inserting the stripping plate and the table by simple transverse sliding in the passage direction of the web. The invention is useful for reducing the time for assembling and disassembling machine components such as the stripping plate and a needling loom table for maintenance operations, in particular cleaning operations.

    Abstract: A fiber glass mat adapted to reinforce thermoplastic polymeric molding material is provided with improved flow properties in the molding process without sacrificing strength and without unduly increasing loft of the mat. The improvement is achieved by needling the mat from both sides with the number of needle punches per unit area on one side being greater than that on the opposite side.

  • Patent number: 6444292
    Abstract: There is described a needle board (1) for a device for needling a web, comprising a board body (2) of a light metal alloy, in particular a magnesium-aluminum alloy, and a plastic coating (3) cast onto the board body (2) on the side of the board facing the needle tips. To create advantageous constructional conditions it is proposed that the board body (2) preferably consisting of a cross-cut extruded section has undercut grooves (7) at its edges on the side of the board covered by the plastic coating (3), where the plastic coating (3) cast thereon positively fills the undercut grooves (7).

  • Patent number: 6311375
    Abstract: A process for producing yarns that have enhanced resistance to unraveling and linting. The yarns are moved along guides through a needle loom where a series of needles engage the yarns. This engagement of the yarns by the needles causes the fibers of the yarns to become intermixed.

  • Patent number: 6233797
    Abstract: A transition part is provided for a felt needle between the clamping part and the working part, which transition part is designed as elongated, narrow truncated cone. The length of this transition part is at least as long as twice the length of the working part. As a result, a very narrow transition region is formed, which has little tendency to pull out and accumulate fibers from the fibrous web. Should fiber deposits still form, these can be removed easily.
