Publication number: 20040154137Abstract: The present invention relates to a sawtooth wire for a cylinder lining, in particular for a doffer cylinder for a carding machine. In order to improve the take-over and delivery properties of the doffer cylinder to a subsequent stuffer cylinder, the sawtooth wire is implemented such that the back angle of the tooth angle of the individual teeth increases from the base to the tip of the respective tooth. Owing to this tooth design, it can be achieved that the tooth back is steep in the area of the tip of the tooth, whereby the delivery properties of the doffer cylinder to the subsequent stuffer cylinder will be improved, while the breast angle is large; this will facilitate the take-over of fibres from the main cylinder that rotates at a higher speed.Type: ApplicationFiled: March 26, 2004Publication date: August 12, 2004Inventor: Axel Bauersachs

Patent number: 5465567Abstract: A fiber opening device for use in a discontinuous spinning process. The opening device includes an opening roller rotatably mounted about an axis and having a cylindrical working surface which extends around the axis. Opening elements are provided around the working surface. A space is defined between an axially outermost fiber opening element and an adjacent outer edge of the cylindrical working surface. A pressure reduction opening is provided for reducing pressure in or around that space. The pressure reduction opening is arranged to urge fibers into engagement with the working surface.Type: GrantFiled: January 19, 1994Date of Patent: November 14, 1995Assignee: Carclo Engineering Group PLC.Inventors: Karl-Heinz Schmolke, Kenneth Lydall

Patent number: 5453146Abstract: A needle bar is made from a support member and a carrier. The needle bar can be made with a plurality of needle grooves. The bar is made by adhering the support member to the carrier. Then the support member is divided into a plurality of individual segments of predetermined length, after the support member is adhered to the carrier. Adjacent ones of the individual segments (a) can be spaced to form a gap narrower in width than the needle grooves, and (b) can have opposing edges shaped to form a concavity having a width equivalent to the needle grooves.Type: GrantFiled: January 31, 1994Date of Patent: September 26, 1995Assignee: Karl Mayer Textilmaschinenfabrik GmbHInventor: Rainer Kemper
