A circular knitting machine for knitted or hosiery items includes a supporting structure; a needle-holding cylinder rotatable around an axis of rotation and supporting a plurality of cylinder needles that are movable for producing a knitted fabric; a dial assembly, arranged above the cylinder and comprising a needle-holding plate rotating around the axis of rotation and supporting a plurality of plate needles that are movable for producing a knitted fabric. The machine includes motion generation elements, in order to rotate the needle-holding cylinder around the axis of rotation, and motion transmission elements configured for forming a motion transmission chain capable of transmitting to the plate, synchronously with respect to the cylinder, the rotation generated by the motion generation elements. The motion transmission elements include a first toothed wheel, receiving the rotary motion of the motion generation elements; a second toothed wheel, mounted coaxially with the needle-holding plate; an offset device, located between the first and the second toothed wheel and comprising an inlet gear, engaged with the first toothed wheel, and an outlet gear, engaged with the second toothed wheel. The inlet and outlet gears are mounted coaxially with one another and are translatable by an actuator, so as to change the engagement of the inlet gear with the first toothed wheel and/or the engagement of the outlet gear with the second toothed wheel.

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.

A wool knitting machine comprising a shell, a knitting device, a yarn feeding device and a clamping device. When each crochet needle reaches the position of a yarn inlet of a yarn feeding port, the clamping device is clamped with the current crochet needle for clamping the wool, and at the same time, an accelerating gear device is arranged in a hand crank to increase the speed of hand knitting, so that a user can make the first knitting circle compact enough without manually tensioning the wool.
