A bent part of a sock has (i) a bulging part having a first bulging region which includes a region in which the number of wales decreases, and a second bulging region which includes a region in which the number of wales increases and (ii) an extended part having a first extended region in which the number of wales increases, and a second extended region in which the number of wales decreases. The extended part is located so as to be closer to a bend direction side than the bulging part. The extended part has a boundary part between the first extended region and the second extended region which boundary part has a bend direction side first end. The bend direction side first end is located on a center line in a direction in which a width of the sock extends, or within a predetermined distance from the center line.

A circular hosiery knitting machine comprising a needle cylinder which can be actuated with a rotary motion about its own axis, arranged vertically, and on the skirt of which there is a plurality of axial grooves, each accommodating a needle, a tubular body being arranged internally and coaxially to the needle cylinder and being adapted to receive the manufactured item during its forming; the tubular body is supported so that it can slide along an axial direction within the needle cylinder; and actuation means which act on command on the tubular body in order to actuate its axial movement with respect to the needle cylinder, the actuation means being associated with means for controlling the speed of the tubular body.

The present invention relates to a seamless foot-covering garment made of knitted courses, a method for manufacturing thereof as well as a respective circular machine for hosiery and knitwear. The foot-covering garment made of knitted courses, comprises a heel portion, a toe portion, a middle portion located between the heel portion and the toe portion and an opening between said heel portion, said middle portion and said toe portion for the insertion of an user's foot. The toe portion and the heel portion are aligned along a longitudinal direction. At said opening the middle portion ends with a right side edge and a left side edge. The garment is seamlessly knitted as a whole. At least one or both the right and left side edges comprise at least one elastic portion made up by a plurality of stretch stitches located at an end of knitted courses. The stretch stitches are composed of at least one main thread of the foot-covering garment knitted with at least one elastic thread. The elastic thread extends with no interruption in said at least one elastic portion, in that it is not cut at each knitted course of said at least one elastic portion.

A process for manufacturing knitwear, hosiery textile items or seamless items with variable compression on circular weft knitting machines, comprising the steps of activating a program for manufacturing a textile (6); manufacturing a textile item (6); and changing the tension of an elastic yarn (9) fed to the needles (4) by a first feeding device (8) of a predefined value of variation and for a predefined number of times, corresponding to at least two times within the same knitting row during the production of the textile, so as to define in said knitting row of the textile a corresponding predefined number of distinct knitting row portions having a differentiated yarn tension, corresponding to at least two portions of the same knitting row; the step of changing the tension of such a yarn being performed independently from the knitted structure produced and also independently from a variation in the position of the stitch adjusting cams (7).

An upper for a shoe includes a first tubular textile layer and a second tubular textile layer. The first tubular textile layer is at least partially surrounded by the second tubular textile layer thus forming an internal textile layer and an external textile layer. The first tubular textile layer includes a first zone. The first zone includes a first yarn and the first tubular textile layer includes a second yarn. The first yarn is more resilient than the second yarn, and the first zone includes a polygonal shape.
