A cylinder mould former includes a second circulating belt and is disposed following the first device in a material transport direction for producing a layer of wet laid fibres having a top side for contacting the second circulating cylinder and being transported thereby for being deposited on the first web. An entangling and bonding device follows the cylinder mould former entangling and/or bonding the first web to the layer of wet laid fibres. A distance of 10 m maximum is maintained between the point of depositing the first web the layer of wet laid fibres. In another embodiment a second device following the first device for depositing a second web. The cylinder mould former is arranged between the first and second devices to deposit the layer of wet laid fibres on the first web before the second web is deposited.Type: ApplicationFiled: September 20, 2024Publication date: January 9, 2025Applicants: TRÜTZSCHLER GROUP SE, VOITH PATENT GMBHInventors: Thomas WEIGERT, Kai PÖHLER, Ralf SCHRÖDER, Andreas SCHILZ

Patent number: 11479884Abstract: A draw device into which at least two filaments are guided for producing a multi-coloured yarn from differently coloured filaments which consist of a plurality of endless filaments includes a pair of intake rollers for receiving the at least two filaments. Two pairs of drafting system rollers follow the intake rollers to draw the at least two filaments. A texturizing device comprising a texturizing nozzle with a cooling drum is disposed downstream of the two pairs of drafting system rollers to texturize the at least two filaments, wherein at least one yarn is formed from the filaments in the texturizing nozzle. At least one further nozzle is disposed exclusively upstream of the texturizing device in which each filament is separately interlaced. The filaments are drawn on at least one of the two pairs of drafting system rollers at a speed of at least 1,700 m/min.Type: GrantFiled: January 11, 2018Date of Patent: October 25, 2022Assignee: Trützschler Group SEInventors: Lassad Nasri, Nuri Kosar

Publication number: 20220251733Abstract: A process for production of a low-shrinkage aliphatic polyamide fibre, in which polyamide is extruded through a spinneret to form filaments, then cooled and combined to form at least one yarn. The at least one yarn is subjected to drawing between the spinneret and a pair of inlet rolls, then in a further multi-stage drawing step is subjected to 4-fold to 6-fold drawing by pairs of draw rolls. The pairs of draw rolls successively heat the yarn and at least the last pair of draw rolls has a temperature of 5° C. to 20° C. below the melting point of the yarn. The yarn is relaxed by from 6% to 10% in a subsequent at least three-stage relaxation zone and is kept in a temperature range of 5° C. to 15° C. below the melting point of the yarn, and is subsequently wound up on a reel device.Type: ApplicationFiled: April 28, 2022Publication date: August 11, 2022Applicant: TRUETZSCHLER GROUP SEInventors: Lassad NASRI, Roman STEPANYAN, Martinus Joseph Maria KEULERS
