Publication number: 20080256757Abstract: The invention relates to an apparatus and a method for depositing synthetic fibers to form a nonwoven, in which the synthetic fibers are blown through a take-up nozzle as a fiber stream in a free space in the direction of a deposit belt. According to the invention, the fiber stream, before impinging onto the deposit belt, is guided by a guide segment formed between two guide members, one of the guide members being arranged on a belt exit side and an opposite guide members being arranged on a belt inlet side and forming, at a distance from the take-up nozzle, an open fiber entry gap for entry into the guide segment, and the guide segment extending as far as the deposit belt.Type: ApplicationFiled: April 24, 2008Publication date: October 23, 2008Inventor: ANTON MOOSHAMMER

Publication number: 20080235915Abstract: In a fleece layer of the carriage cross-lapper type, the laying carriage conveyor belt (14) wraps around the first laying roller (12), the upper and lower strands (14o, 14u) of the belt being parallel to each other as they proceed from the first laying roller (12). An endless cover belt (23), which travels around in the laying carriage (5), wraps around the second laying roller (13), the cover belt having upper and lower strands (23o, 23u), which are parallel to each other as they proceed from the second laying roller (13) in the direction opposite that of the laying carriage conveyor belt (14).Type: ApplicationFiled: March 27, 2008Publication date: October 2, 2008Applicant: OSKAR DILO MASCHINENFABRIK KGInventor: Johann P.

Publication number: 20080235916Abstract: A fleece-laying apparatus with an upper carriage (4) and a laying carriage (5) which move above an output conveyor belt (2) transversely to the transport direction of that belt to lay a card web (11) supplied to the fleece layer in partially overlapping layers on an output conveyor belt (2), an endless card web conveyor belt (14) traveling exclusively in the laying carriage (5) wraps around at least one first laying roller (12) in the laying carriage (5). The belt has upper and lower strands (14o, 14u), which extend between the first laying roller (12) and a deflecting roller (15), which is supported in the laying carriage a certain distance away from the laying roller and around which the belt partially wraps.Type: ApplicationFiled: March 27, 2008Publication date: October 2, 2008Applicant: OSKAR DILO MASCHINENFABRIK KGInventor: Johann P.

Patent number: 7418769Abstract: This invention relates to a kind of down branch fiber fabric, its fabricating method and device. The fabric is composed of 10-100% down branch fiber and 0-90% textile fiber by weight. The processing steps include material choosing, silver feeding, twisting, winding packages, heat setting and weaving. The device comprises a raw material tank, a feeding conveyer belt, a inclined feeding conveyer belt, a adjustable even roller, a brambly catching roller, a first subsiding room, an even roller, a brambly dividing roller, a second subsiding room, two dust cages. The present invention makes the down branch fiber spinnable and weavable. It solves the problem that the down branch fiber cannot be combed and drawn and drafted by the prior textile technique, so that chances the fact that the down branch fiber can only be used as the fiber stuffing to make down garments, quilts, ticks and other bedding. This new fabric is applicable to make thermal woven, hoses, quilts, ticks or other bedding.Type: GrantFiled: November 17, 2003Date of Patent: September 2, 2008Assignee: Foshan Shengu Textile Company, Ltd.Inventor: Liwen Zhang

Publication number: 20080178812Abstract: A pet bed such as a dog bed having a filler material that includes a fiber batt, the fiber batt having been formed by garnetting fibers to form a fiber web and cross-lapping the fiber web to form the fiber batt. The bed is advantageously resistant to wear and is resistant to the formation of depressions in the bed by the pet. A method for making the pet bed is also provided.Type: ApplicationFiled: January 31, 2008Publication date: July 31, 2008Applicants: TOPET USA, INC., INTERNATIONAL TRADING COMPANY, LLCInventors: Edward P. Dennis, John D. Love

Publication number: 20080178432Abstract: In an apparatus in spinning preparation for separating foreign objects at conveying equipment for fibre material, at least one separation device is associated with the conveying equipment. The separation device comprises an arrangement for producing a blast of air that flows in the direction onto the conveying equipment and generates an air flow that detaches the foreign objects from the conveyed fibres and carries them away. The arrangement comprises a plurality of blast nozzles arranged across the width of the conveying equipment and connected to a compressed air pipe and to valves. To reduce the proportion of good fibres in the waste in a simple manner, and to allow a more selective action of the blast air current, a bar member for mounting the blast nozzles is present and the nozzles are integrated in the bar member.Type: ApplicationFiled: January 23, 2008Publication date: July 31, 2008Applicant: Truetzschler GmbH & Co.

Patent number: 7331089Abstract: A method and apparatus is described for use in dry forming a fabric by at least two non-woven fabrics. The upper run of the transfer wire is used as a forming wire. A forming head is disposed above the transfer wire. An airlaid non-woven fabric is formed on the transfer wire. This non-woven fabric is carried with the transfer wire onto the top side of the first non-woven fabric. The first non-woven fabric is formed on a preceding forming wire and transferred by the transfer wire to a subsequent conveying wire. This subsequent conveying wire can also be a forming wire so further non-woven fabric can be formed before the fabric is consolidated, e.g. by hydroentanglement or latex bonding/fibre bonding.Type: GrantFiled: April 28, 2004Date of Patent: February 19, 2008Assignee: Dan-Web Holding A/SInventor: Kenn Mosgaard Christensen

Patent number: 7320155Abstract: Apparatus for variably buffering a web material, the apparatus having two endless transport belts including feed sections in which the belts are juxtaposed, and return sections, the feed and return sections being of varying lengths. In the feed sections, the belts move through a U-shaped path portion, commonly guided over a deflecting roller. In the return sections, the belts are guided through U-shaped path portions extending opposite to the U-shaped path portion of the feed sections, each belt wrapping separate deflecting rollers. The three deflecting rollers are rotatably supported on a common mounting frame movably held in a machine stand for compensated length variation of the feed and return portions.Type: GrantFiled: March 8, 2005Date of Patent: January 22, 2008Assignee: Oskar Dilo Maschinenfabrik KGInventor: Joachim Leger

Patent number: RE42765Abstract: A plant serves as a mean for production of a fibre web of synthetic fibres, such as plastic fibres and absorbent fibres, such as viscose and cellulose fibres. The plant includes a forming head preliminary to lay a homogeneously and smoothly distributed fibre layer on a net shaped wire. Furthermore the plant includes a hydro-entangling section with liquid nozzles with powerful liquid jets to treat the in the forming head formed fibre layer, which consists of both synthetic—and absorbent fibres. The plant also includes an oven subsequently to thermal bond the synthetic fibres with cross bonds in the affected areas. Finally the dried web is winded up in a roller. By the help of the plant according to the invention, by higher production speed than known previously a fibre web can be produced, which is far cheaper, and which has a better and more homogeneous structure than similar conventional fibre webs.Type: GrantFiled: October 12, 1998Date of Patent: October 4, 2011Assignee: Oerlikon Textile GmbH & Co.
