Publication number: 20140230118Abstract: The invention addresses the problem of providing a warp knitted fabric manufacturing method capable of stably producing a warp knitted fabric wherein the longitudinal stretchability is 200%. To solve the problem, the invention is a warp knitted fabric manufacturing method that forms bands of a warp knitted structure with increased longitudinal stretchability by forming stitches with an elastic warp (2) while knitting in an elastic inserted yarn (3) in the warp direction and knitting in the weft (4) in the course direction, wherein: active feed means (30), which are obtained by placing a single follower roller (323) above two drive rollers (321, 322), are disposed on the respective paths of the warp (2) and the inserted yarn (3) to feed the warp (2) and the inserted yarn (3) to the warp knitting machine while increasing the respective elongation percentage.Type: ApplicationFiled: August 30, 2012Publication date: August 21, 2014Applicants: TAKENAKA SENI CO., LTD., IRIS CO., LTD., KOIZUMI BRAID INC.Inventor: Satoru Koizumi

Patent number: 6658709Abstract: A method for manufacturing a shrink fabric, and a shrink fabric to be used for filtering. The method is used for manufacturing a shrink fabric (1, 1′) comprising a seam assembly (4) which is substantially diagonal with respect to the lateral direction of the shrink fabric (1, 1′). When arranged in place onto a drum filter, the seam assembly (4) of the shrink fabric (1, 1′) is substantially diagonal with respect to the lateral direction of the drum (2) of the drum filter.Type: GrantFiled: October 19, 2001Date of Patent: December 9, 2003Assignee: Tamfelt OYJ ABPInventors: Aulis Perälä, Eino Sorri

Patent number: 5189769Abstract: A method of making a multi-layer non-woven multiple biased fabric is disclosed. A layer of fabric is directed in a longitudinal direction of travel, wherein the layer of fabric is comprised of a plurality of structural fibers oriented substantially parallel to each other and oriented at an angle to the longitudinal center line of the fabric. The layer of fabric may or may not be previously biased. If not previously biased, then the structural yarns of the fabric are biased in a biasing stage to form a layer of single bias structural fabric having the structural fibers biased to the fabric centerline. The single biased fabric layer is led into at least one folding stage for folding the biased layer longitudinally from one edge toward another to form a multiple biased fabric. The multiple biased fabric is led from the at least one folding stage into an affixing stage for affixing the multiple biased fabric together to provide a single structural fabric being multiple biased.Type: GrantFiled: June 1, 1990Date of Patent: March 2, 1993Assignee: Bay Mills LimitedInventor: Roy Shoesmith

Patent number: 4567738Abstract: A structural fabric (20, 28, 40, 48) and a method for making the same is disclosed. Structural fabric (20) is comprised of a plurality of substantially parallel, uniaxial structural yarn (22) and a secondary yarn (24) for holding the structural yarns (22) in place. The structural yarns (22) are oriented at an angle skewed from both the fabric centerline (26) and a line perpendicular to the fabric centerline (26).A double biased fabric (28) is made by sewing two fabrics (20) together with secondary yarn (39). An alternate double bias fabric (40) is made by sewing together with secondary yarn (46) the two layers of a flattened helix made from structural yarn (42, 44) running spirally substantially the length of the fabric (40).A triaxial fabric (48) is made by sewing together with a secondary yarn (56) two single biased fabrics (50, 52) and a layer of longitudinally-extending structural yarn pieces (54).Type: GrantFiled: November 26, 1980Date of Patent: February 4, 1986Assignee: Knytex, Inc.Inventors: Harold K. Hutson, Ronald G. Krueger

Patent number: 4097621Abstract: A method is provided for manufacturing a bias fabric provided with characteristic physical properties by continuously varying the intersecting angle between the warp and the weft by a mechanical device. A fabric subjected to the process according to the invention can be any type of fabric woven on conventional looms such as satin, twill, plain and duplex fabrics.Type: GrantFiled: October 7, 1976Date of Patent: June 27, 1978Assignee: Mitsuboshi Belting Ltd.Inventors: Kaname Shirasaka, Yoshihiro Nakagami, Takashi Tomiyori, Masanori Ikemoto, Tsuneo Shaura
