A needle-holding element for circular knitting machines, having a structure as a hollow solid of rotation developing around a central axis and configured for rotating and for supporting a plurality of needles moving so as to produce a knitted fabric; the needle-holding element has at least one working surface shaped as a surface of rotation obtained through the rotation of a portion of generating straight line around the central axis; on the working surface a plurality of needle seats is defined, placed one beside the other and arranged circumferentially or radially around the central axis, wherein each needle seat movably houses at least a portion of at least one respective needle. At least one needle seat has at least a first length has a longitudinal development, on the working surface, inclined with respect to the generating straight line.

A jacquard fabric for a mattress ticking to be used for a bedding mattress and a method for knitting this jacquard fabric are provided. The method is for producing a jacquard fabric for a mattress ticking using a double-sided needle selection circular knitting machine of a rib gating type by which an arbitrary pattern is created by means of computer-based needle selection on a cylinder side, an arbitrary pattern is also created by means of computer-based needle selection on a dial side, and an arbitrary knitting structure is made in an arbitrary part by combining the pattern obtained on the cylinder side with the pattern obtained on the dial side. As a result of employing an irregular twill pattern as a background knitting structure serving as a base, a stretchable fabric that has a soft texture, a tight knitting structure, and strength similar to that of woven fabric is obtained.

The present device is a circular knitting machine, also known as a circular sock machine, designed to mostly be manufactured from polymers, such as plastics, or other materials that are typically lighter and have other physical properties, such as low hardness and tensile strength, compared to steel, from which such machines have historically been manufactured. The present design allows for the use of modern manufacturing techniques, such as 3-D printing in which a filament is often used comprising various types of polymers. The present device can also comprise a ribber apparatus, which is also designed to allow for most of its parts to be manufactured from polymers. However, in certain embodiments, some of the parts, such as needles, springs, and bolts can still be made from steel.

A single- or double-knit circular knitting machine having a cylinder (11) equipped with cylinder needles and/or a dial equipped with dial needles for the production of single- or double-jersey knitted webs, which machine has at least one thread-selection device, threads being able to be supplied to any cylinder- and/or dial needle by the thread-selection device.

The present invention relates to a method for weaving a single fabric, the method comprising: alternately forming a clearing position and a half-tuck position at a first-stage cylinder cam; and forming a half-tuck position and a clearing position at a second-stage cylinder cam formed under the first-step cylinder cam, wherein the half-tuck position of the second-stage cylinder cam is positioned under the clearing position of the first-stage cylinder cam, and the clearing position of the second-stage cylinder cam is positioned under the half-tuck position of the first-stage cylinder cam, and wherein a non-covered yarn is supplied to the clearing position of the first-stage cylinder cam, and a covered yarn is supplied to the half-tuck position of the first-stage cylinder cam.

A circular knitting machine (1) for knitwear or hosiery, comprising a bearing structure, needle cylinder (C), a plurality of needles, and a dial group. The dial group comprises a support ring (4), a hook plate (5), and a thread feeding and cutting organ. The knitting machine comprises rotation transmission means (10) comprising: a drive pulley (11), a hook plate shaft (12), a flange (13) and an engaging mechanism (20) which operates between an engaged configuration, in which it constrains the pulley and the flange to one another, and a disengaged configuration, in which the flange is free from constraints. The engaging mechanism comprises an engaging organ (21) and actuating means (30) which enable the passage from the engaged configuration to the disengaged configuration in any angular position assumed by the flange or the pulley, and the passage from the disengaged configuration to the engaged configuration with the engaging organ positioned at a predetermined number of angular engaging and disengaging positions (40).

A knitting method and an apparatus for a cylindrical biaxial weft-knitted three-dimensional knitted structure. The biaxial three-dimensional knitted structure comprises two weft plain stitch structures (7, 7), a group of spacer yarns (416), two groups of weft inserting yarns (415, 415) and a group of warp inserting yarns (43), wherein the two groups of weft inserting yarns are used for selective weft inserting on a needle dial (11) or a needle cylinder (13), the warp inserting yarns are positioned between the two groups of weft inserting yarns, the two weft plain stitch structures are connected with each other by the group of spacer yarns, for jointly clamping the weft inserting yarns and the warp inserting yarns, in order to form a biaxial weft-knitted three-dimensional knitted structure. Such three-dimensional knitted structure improves the mechanical properties of three-dimensional knitted fabrics; by increasing the interval between the needle dial and the needle cylinder, the thickness of the knitted structure is increased, which is suitable for the reinforced structure of high-performance structural and functional composite materials, and expand the field of the use of the knitted structures.
