Abstract: A system of cams and a sinker for terry cloth knitting using the needles on circular knitting machines and stocking knitting machines. Cam means (20, 21, 22) are provided for selectively interacting with a control bottom part (18) and with a shoulder (19) for the inlet and outlet differential longitudinal movements of each sinker in relation to the needles for a selective plain stitch formation at a horizontal plane (14), a terry cloth stitch at a top mouth (15) and a mixed stitch at an intermediate notch (17) on the head of the sinker proper.

Abstract: A device for the selection of the sinkers for the manufacture of designed terry cloth knitwear on circular knitting machines and stocking knitting machines. Each sinker (13) is capable of oscillations in a vertical plane between a canceled, resting position, in which its tail end (21) is not intercepted by a return cam (24), and an operating position, in which its tail end interacts with the return cam for the longitudinal movements of the sinker. The sinker also has a bottom part that interacts with inlet and outlet cams, and the sinker can be moved from the canceled, resting position to the operating position by a selection device acting on an oscillating selector associated with the shaft of the sinker.

Abstract: A sinker (1) for a circular knitting machine contains a shaft (2) with a recess (11) in which a selection element (12) provided with a controllable raising butt (20) is mounted swivellably and can be swivelled to and fro between a position in which the raising butt (20) is retracted into the recess (11) and a position in which the raising butt (20) projects upwards over the upper side of the shaft (2). A spring (21), which can be attached to the selection element (12) or the shaft (2), serves to pre-tension the selection element (12) into one of these two positions (FIG. 1). In addition, a selection device is provided for selecting the sinker (1) in accordance with a pattern.

Abstract: An elongate support body includes each of a plurality of pistons longitudinally translatable to urge movement of a corresponding sinker in a straight bar knitting machine. A piston chamber is disposed within or attached to the support body and includes a translatable piston head disposed therewithin. Each of a plurality of piston cylinders housing the respective ones of the plurality of pistons is in fluid communication with the piston chamber. Upon introduction of a fluid under pressure into the piston chamber on one side of the piston head, fluid pressure will be introduced serially into each piston cylinder to actuate each piston as the piston head translates along the piston chamber.

Abstract: A knitting machine has multiple stage sinkers which have multiple stages of butts in the rear part. A cam track fashions complicated patterns using the multiple stage sinkers. A mechanical or electronic device is installed to a top plate on an upper portion of a circular knitting machine. This device controls the sinkers.

Abstract: A set of cams for actuating the lowering sinkers in circular knitting machines, for producing standard-terry knitting and sandwich-terry knitting. The cam set comprises cams and countercams which form a path for the heels of the lowering sinkers which have two lowering planes arranged at mutually different elevations for at least two yarns which are dispensed at a feed of the machine to form loops of terry knitting. The cam set also comprises, in the region of the path that corresponds to the descent of the needles of the needle cylinder to form loops of knitting with the two yarns dispensed at a feed of the machine, a cam which can move on command into two operating positions in order to produce at least one variation of the path formed by the cams and countercams.

Abstract: A circular knitting machine and a jacquard pattern control mechanism therefor is provided in which knitting instrumentalities slidably mounted in grooves in a rotating member, such as a needle cylinder, sinker cap or dial, are controlled by a rocker bar supporting member slidably mounted in each groove behind the knitting instrumentality, the rocker bar supporting member having at least one butt thereon, a rocker bar pivotally mounted on the rocker bar supporting member and having magnetically attractable sections at opposite ends thereof, a magnetic attraction device selectively attracting the magnetically attractable sections of the rocker bar to pivot the rocker bar to control the selection of knitting instrumentalities to be moved from inactive to active positions and a cam system for moving the rocker bar supporting member and selected knitting instrumentalities.

Abstract: The machine is provided with casting-off sinkers having two casting-off surfaces which are mutually spaced in a direction which is parallel to the axis of the needle cylinder to form toweling stitches. The machine has auxiliary jacks which are accommodated in axial grooves of a needle cylinder and can move, when actuated, along these grooves parallel to the axis of the needle cylinder so as to act, with their upper end, on the casting-off sinkers to move them in a direction which is radial to the needle cylinder from a rearward position, in which they receive two threads engaged by the contiguous needles on a same one of the two casting-off surfaces, forming two loops of knitting of equal length, to an advanced position in the direction of the axis of the needle cylinder, in which they receive the two threads engaged by the contiguous needles respectively on one of the casting-off surfaces and on the other casting-off surface so as to form two loops having mutually different lengths, i.e. toweling stitches.

Abstract: An improved sinker cam assembly for a circular knitting machine is disclosed which contains a series of cam segments attached to a stationary circular cam ring to form an endless undulating cam race. The assembly also includes a rotating sinker ring to which a plurality of sinkers are slidably attached for reciprocal movement as the sinker ring rotates relative to the cam ring. Each sinker conventionally contains a radially inwardly located, axially extending cam follower arm and a spaced apart, radially outwardly located, axially extending cam follower arm. The arms confine the cam surfaces of the cam race therebetween so that the cam surfaces control the reciprocal movements of the sinkers as the sinker ring rotates. The cam elements contain gaps between successive pairs thereof, which have gap openings on the two cam surfaces.

Abstract: A device for selecting needles in a circular knitting machine of the elastic jack type, comprising auxiliary jacks positioned below and in the same tricks as the elastic jacks. The auxiliary jacks are selected electromagnetically so that they act to radially lock the elastic jacks while these are in their flexed position within the tricks so that they cannot return outwards and thus engage their raising cams and activate their needle.

Abstract: A device for forming, terry knit with a terry yarn and a base yarn for the base fabric. A needle cylinder is provided including a plurality of needles, driven for reciprocating motion. A plurality of sinkers with a high nose for the terry yarn and a plurality of sinkers with a low nose for the base yarn are provided. A high yarn guide for the terry yarn, is provided at a high yarn guide level and a lower yarn guide for the base yarn is provided at a lower level than a level of a surface of the high-nosed sinkers. A fixed annular sinkers housing is provided including a fixed cam profile to control radial movement of the high-nosed sinkers. The cam profile has an area of centrifugal retraction substantially symmetrical with respect to a feeding position of the high yarn guide and the lower yarn guide. An angularly mobile annular sinkers housing is provided for controlling radial movement of the low-nosed sinkers.

Abstract: The circular knitting machine for socks, stockings or the like, in particular for producing knitting with towelling stitches, comprises, at the set of knitting-forming cams which actuate the motion of the needles during the engagement of the thread or threads at one feed of the machine, an additional cam. The additional cam is arranged above the central cam and defines a descending portion which is engageable with the heel of the needles, excluded from knitting at that feed and raised with respect to the needles which knit at that feed. The controlled lowering of the needles which do not knit at the feed facilitates the positioning of the thread or threads fed at the feed and the correct forming of the loops by the needles which knit at that feed.

Abstract: A circular knitting machine includes a cylinder spacedly provided with vertical slits on its overall circumference, and sinkers and knitting needles alternately mounted in every other slit of the cylinder. Each one of the sinkers is formed on its bottom side with a cutout so that a sinker selection jack moving up and down within the slit pushes the slant front edge of the cutout to move the sinker horizontally, or towards the center of the cylinder. With the structure, the movements of the sinker can be individually controlled to form a pile patterning and reversed patterning.
