Abstract: A durable cylinder assembly for a circular knitting machine is described. The cylinder assembly includes a cylinder body having an outer cylindrical face and an upper face including a plurality of spaced-apart substantially radial channels. A shaped circumferential indentation circumscribes an upper end of the outer cylindrical face, and a hardened circular band is matingly engaged with the indentation to define a durable bearing surface for reciprocating elements the knitting machine, e.g. the sinkers and/or needles. The hardened band is preferably formed of heat treated metal and has a discontinuous circumference defined by a single cut, which is preferably single or double biased. The indentation provided in the cylinder body is desirably in the form a right angle, and the band preferably has a rectangular cross-sectional configuration so as to mate securely with the indentation.

Abstract: A circular knitting machine with needles having operating butts of predetermined height includes a stitch cam unit for raising and lowering the needles by engaging the operating butts. The cam system includes a support body and a needle raising cam block having upper and lower cam members fixed to the support body and having corresponding upwardly inclined lower and upper butt engaging surfaces which are spaced from each other a distance substantially corresponding to the dimensions of the predetermined height of the needle butts. The upper cam member also includes a downwardly inclined lower butt engaging surface extending from the top portion of the upwardly inclined lower butt engaging surface for engagement with the needle butts. A stitch cam member has a downwardly inclined lower butt engaging surface cooperating with the downwardly inclined lower butt engaging surface of the needle raising cam.

Abstract: An attachment for use with multi-feed circular knitting machines of the type having a rotary needle cylinder and having yarn striper boxes at the feeds thereof. The boxes serving to change and to cut and clamp the yarns fed to and knit by the machine during the making thereon of coursewise striped fabric. The yarn changing operation resulting in undesirably long unknit terminal portions of the changed yarns extending inwardly from the inner side of the tubular fabric being made. The terminal portions of the yarns having cut ends. The attachment comprising a device having yarn clipping means disposed within the tubular fabric and rotating in unison with the needle cylinder to cut and to shorten the terminal portions of the changed yarns as the tubular fabric continues to be made, whereby the yarns are cut firstly by the striper boxes and secondly by the yarn clipping means.

Abstract: Tubular knitted high pile fabric of indefinite length is formed in a novel manner so that after walewise split lengths of the tubular fabric are coursewise seamed together to form an indefinite length of flat high pile fabric, the seam can be so formed that the flat fabric is able to pass through the fabric finishing apparatus without damage to the apparatus by the seam and without special control of the apparatus to permit the seam to pass therethrough. The novel tubular knitted high pile fabric is specially formed with the pile omitted at walewise spaced courses thereof to form walewise spaced bands of non-pile fabric, and the seam is then formed in the non-pile fabric.

Abstract: A knitted undergarment as formed from a knitted blank made entirely by rotary knitting upon a circle of needles of a circular knitting machine by first knitting a seamless tubular elastic waist encircling turned welt upon all of the needles, then knitting a seamless tubular body section in continuation of the welt upon all of the needles, and then knitting spaced seamless nontubular front and rear narrowed panels in continuation of correspondingly spaced portions of the body section upon correspondingly spaced groups of the needles, the yarn being introduced to the needles for the knitting of each course of the panels and being cut and clamped after the knitting of each such course, so that each course of the narrowed panels is knit of a separate length of yarn. The knitted undergarment is completed by joining the terminal end portions of the panels. The narrowed edges of the spaced panels then delineate spaced leg openings therebetween.
