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.

The linking device (9) includes a first bowed needle (17) mounted on a first shaft (13) and a second bowed needle (19) mounted on a second shaft (15). The first shaft (13) and the second shaft (15) are mutually inclined to each other and are controlled in order to pivot alternatingly around a pivot axis (A-A) of the first shaft (13) and a pivot axis (B-B) of the second shaft (15), respectively. The first shaft (13) is rigidly coupled to a first pin (27) pivoting therewith; the second shaft (15) is rigidly coupled to a second pin (31) pivoting therewith; and a slider (35) is slidingly mounted on the first pin (27) and on the second pin (31).

A knit garment is provided to be worn on the foot that has a toe, foot, and heel area. The garment also has a medial triangular ankle panel and a lateral triangular ankle panel. The medial triangular ankle panel has a first medial vertex near the rear, top portion of the foot area, a second medial vertex near the top of the heel area, and a third medial vertex below and between the first and second medial vertices. The lateral triangular ankle panel has a first lateral vertex near the rear, top portion of the foot area, a second lateral vertex near the top of the heel area, and a third lateral vertex below and between the first and second lateral vertices. The sides of the medial and lateral triangular panels extending between the respective first and second medial and lateral vertices define an opening of the garment for a foot.

A circular knitting machine includes a needle-holding cylinder, having longitudinal grooves arranged around a central axis and housing a plurality of needles, and a needle-holding ring having radial grooves housing a plurality of holding-down sinkers, wherein each needle is paired with at least one respective adjacent sinker so as to form a needle-sinker assembly. Each needle-sinker assembly includes a pre-selection element paired with the respective needle and comprising a connecting portion and an activation element comprising an operating portion. The pre-selection element is vertically movable to a pre-selection configuration in which the connecting portion is engaged into a connecting seat defined in the sinker. The activation element is horizontally movable, towards the central axis, until acting upon the pre-selection element, so that the connecting portion causes in its turn a movement of the sinker in the radial groove towards the central axis, thus performing an activation of the sinker.
