    Abstract: A seaming element for joining opposed ends of woven or nonwoven industrial textiles, textiles including seaming elements, and methods of making a seam area for textiles. The seaming element comprises a continuous filamentary structure, configured as first and second layers of aligned looped segments, each segment of one layer being connected to adjacent segments of the other layer by a connecting portion. The seaming elements can be bonded directly to the fabric edges, or inserted into the fabric so that free ends of the looped segments engage and are secured by selected MD yarns or components. Connecting portions of complementary elements when interdigitated together define a continuous channel to receive a pintle. The seaming element is readily and securely installed in the textiles, and overcomes problems of alignment of fabric ends for securing a seam, while minimizing any disruption in fabric properties adjacent the seam area.

    Abstract: A weaving machine arrangement incorporates a shaft frame machine and, arranged on both sides thereof, two Jacquard machines. The weaving machine arrangement is coordinated/controllable and first warp threads for the woven material are obtained from the shaft frame weaving machine and second warp threads are obtained from the Jacquard machines. A tubular material is formed from top and bottom plies which are connected by turnover fold areas. The second warp threads are used to form the spread-out turnover fold areas in the tubular material. The Jacquard machines are controlled to form patterns for closing locations of the weft threads in the turnover fold areas. By using spread-out turnover fold areas and spreading the closing locations of the weft threads in these areas, high-strength piecing functions are obtained in the tubular weave. Also, the level of automation is increased in relation to conventional production.

  • Patent number: 5003675
    Abstract: A separator for successively seizing threads held in an array includes a frame, in which at least one plate is guided for seizing the threads. The frame is displaceable toward and away from the array. Each plate carries a piercing needle which pierces the thread for seizing it. Each plate can have two piercing needles disposed at a distance from one another and pointing towards one another.

  • Patent number: 4974300
    Abstract: The invention concerns a thread separator for seaming machines, especially the seaming of dewwatering webs, drying webs, felts and so on. The object underlying the invention consists therein to optimize the reliability of the function of the thread separator by configuring their gripper needles such that the singling out of each foremost thread of a row of warp threads of the web is ensured and each piercing and taking with of the following thread is avoided. It is proposed to construct the gripper needles as separator needles, providing them with special hooks, of which at least two are located with respect to the upper side and the lower side of the web strip related to the row of threads in the same or parallel level opposite to one another, the tips thereof being directed to the opposing thread surface, respectively. The separator needles are provided with concave apertures adpated to the diameter of the thread which is to be separated on grasping it.

  • Patent number: 4948646
    Abstract: The invention provides a press felt seam comprising a first felt end and a second felt end interconnected by hinge means wherein the soft cover layer on the first felt end is configured to provide a flap element overlaying said hinge means, and the soft cover layer on the second end is configured to support said flap. The surface of said flap contiguous the hinge means is provided with a resilient support material to impart to the seam area a compression recovered thickness substantially equal to or slightly greater than the rest of the felt.

  • Patent number: 4902383
    Abstract: An improved seamed papermaker's press felt of the type having a pintle seamed base fabric and at least one layer of batt material affixed thereto is disclosed. The improvement resides in the provision of an angled slit through the batt material adjacent to the seam. By means of the angled splice, a need for a flap overlying the seam is avoided.

  • Patent number: 4866821
    Abstract: A separator for successively seizing threads (14) held in an array (28) includes a frame (10) having a front face or recess gap (12) and in which two or more strap or bar needles (15, 16, 18) are slidably disposed side by side. Each needle is provided with a pair of facing hooks (20, 22; 24, 26) at opposite sides of a cutout in its forward edge for cooperatively seizing a single thread for separation when the needles are driven in opposite directions.

  • Patent number: 4865083
    Abstract: A seam is provided for a papermaker's felt for use in a papermaker's machine. The seam joins a felt having at least four layers of machine direction yarns in which at least two layers at each end of the felt are finished in loops, and the remaining layers are finished with or without loops. The loops of the ends to be joined are mated, and a pintle is inserted to close the seam.

  • Patent number: 4862566
    Abstract: An auxiliary device for a seam weaving machine for joining the ends of flat-woven fabrics by a woven seam couples each auxiliary warp thread to a tensioning string. The auxiliary device includes a barbed needle in a guide sleeve with the barbed needle having at one end a barb for seizing an auxiliary warp thread and holding it between the needle and the sleeve. The needle is connected at the other end to a tensioned string. A storage plate is provided having bores for receiving the coupling devices.

  • Patent number: 4842925
    Abstract: Process of manufacturing a papermakers' wet press felt for the wet end and a felt produced thereby with one or two flaps (14, 10), made of two batts (12, 13) needled onto each side of the felt (1), which ends in two rows of loops (4, 5) that are intended to seam the felt, characterized in that the rows of loops (4, 5) are joined during needling by temporary, removable connecting means (6) placed in relation to the flap(s) (14, 16) which have a greater width than the widths of the finally cut flaps (14, 16).The flap(s) (14, 10) are not damaged during the needling operation and are easily loosened without damage by removing the spiral (7) which form the temporary joining means (6).
