An electronic yarn changing device for a circular knitting machine includes at least two driving units, at least two impelling plates respectively connected to the driving units, and at least two yarn feeding units. The impelling plates are impelled by the respective connected driving units to perform a one-dimensional motion. The yarn feeding units are arranged side by side, and are each provided sequentially with a yarn feeding plate, a yarn clamping plate, a mobile blade plate and a fixed blade plate. The yarn clamping plate includes a plurality of guide columns disposed correspondingly to the yarn feeding plate. The yarn feeding plates are respectively pushed by the corresponding impelling plates to perform a two-dimensional motion due to the plurality of guide columns. The mobile blade plates are also respectively pushed when the corresponding impelling plates perform the one-dimensional motion, and individually perform a one-dimensional motion once being pushed.

A device for feeding yarn or yarns for knitting machines for hosiery or the like, comprising a supporting structure which supports at least one yarn finger having an elongated shape and being pivoted, at an intermediate portion thereof, to the supporting structure about a corresponding rotation axis and having, proximate to a longitudinal end thereof, a passage for the yarn or yarns to be fed to the needles of the knitting forming machine, the device for feeding yarn or yarns comprising an electromagnetically actuated device which comprises at least one magnet which is fixed to the at least one yarn finger and at least one electric coil which is laterally adjacent to the at least one yarn finger and is connected to the supporting structure.

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 process and system for forming an apparel fabric having a predetermined requisite optical colour and pattern effect and predetermined physical fabric properties are disclosed. The process comprises the steps of: (1) providing a first plurality of n yarn; (ii) providing at least one further plurality of m yarn; and (iii) knitting the first plurality of n yarn with the at least one further plurality of m yarn by way of a knitting process to form a multi-ply apparel fabric; wherein each yarn is formed from a plurality of fibers formed from a polymeric material, wherein the fibers are formed from a dope dyeing process and wherein the fibers are colored during the dope dyeing process; wherein upon knitting the first plurality of n yarn with the at least one further plurality of m yarn to form the multi-ply apparel fabric, the apparel fabric is formed having the predetermined requisite optical colour and pattern effect devoid of optically detectable variants in the requisite optical colour and pattern effect; and wherein the first plurality of n yarn and the at least one further plurality of m yarn are selected to provide the predetermined requisite optical colour and pattern effect and the predetermined physical fabric properties.

A circular hosiery knitting machine, particularly of the double cylinder type, with yarn finger for plated knitting, comprising at least one needle cylinder and a first yarn finger for dispensing a base yarn and a second yarn finger for dispensing a reinforcement yarn; the dispensing end of the body of the second yarn finger can move on command with respect to the remaining part of the body of the second yarn finger, on a plane that is substantially perpendicular to the axis of the needle cylinder, along a direction that is substantially parallel to the tangent to the needle cylinder in the grip point, by needles, of a reinforcement yarn dispensed by the second yarn finger.
