An open-type circular knitting machine for the open and width-variable web production with a knitted fabric take-down and/or collecting assembly, including: a basement, knitting head and take-down and/or collecting assembly for the fabric. The head is equipped with a needle-holding element having a plurality of needles arranged around a central axis; a first and last active needle delimit a dead zone of the element without needles, and an arc-shaped operating zone with active needles. The head has a control device connected to the active needles to selectively actuate them to produce an open knitted fabric extending between two side edges making up two selvedges of the fabric. The assembly is downstream from the head with respect to feeding direction of the fabric, configured for rotating integral or coordinated with the element during production. Further, at least a first cutting device, configured for progressively cutting and/or trimming the produced fabric.

A method of making a sheared wool, deep pile fabric that closely resembles natural sheepskin fleece, that includes forming a yarn made from wool fibers and simultaneously knitting the yarn and a scrim together, where the yarn is attached to and extends from the scrim to form a length of wool pile fabric having natural wool fibers on one side and the scrim on an opposing side. The method includes finishing the wool pile fabric as natural sheepskin by polishing the wool fiber side of the pile fabric by guiding the length of pile fabric over plural heated polishing rolls, where at least two of the plural heated polishing rolls rotate in opposite directions, and cutting the wool fibers to a designated length.

A method is disclosed for producing a knitted article with two leg pieces and one body on a circular knitting machine with at least one circular needle bed. The method comprises the following steps: a) knitting a first leg piece (3) with continuous motion; b) knitting a first pocket (17) of fabric with continuous motion, starting from an end course (23) of the first leg piece (3); c) knitting a central part (15) of said body with continuous motion; d) knitting a second pocket of fabric (19) with continuous motion starting from the central part of the body up to a start course (29) of a second leg piece (5); e) knitting the second leg piece (5) with continuous motion starting from the start course.

A circular knitting machine for knitting a pile fabric with short stitch length, the circular knitting machine includes a needle dial, a needle bed, a gap formed by the needle dial and the needle bed, knitting needles on the needle dial, crochet needles on the needle bed, a cutter holder, and cutters on the cutter holder and facing the gap. Movement tracks of the crochet needles are crisscrossed with movement tracks of the knitting needles and movement tracks of the cutters. Each of the crochet needles has a butt portion, a hook portion, and a protruding shoulder portion between the butt portion and the hook portion, the protruding shoulder portion forms an eyelet, and the protruding shoulder portion is configured to be capable of expanding a yarn loop on the crochet needles to facilitate the cutters to cut the yarn loop at the eyelet to form a pile.

The present invention relates to an openwork prosthetic knit (1) made from a single piece based on at least a first yarn made of biocompatible polymer material that defines a first face (2) and a second face that are opposite one another and from a second biocompatible yarn that generates barbs (5) that protrude outwards from at least said first face, characterized in that said first face comprises at least one longitudinal strip (4) in the direction of the manufacture of said knit, over which it is provided with said barbs (5), and at least one longitudinal strip (3) in the direction of the manufacture of said knit, over which it is free of such barbs. It also relates to a process for manufacturing such a knit (1) and to a prosthesis comprising such a knit (1).
