Abstract:
A slider for a double-cylinder circular knitting machine, having lower and upper needle cylinders including curved surfaces thereof, axial slots formed in said curved surfaces, and a plurality of needles, the slider comprising: an elongated laminar body having a longitudinal extension between two opposite ends thereof, said elongated laminar body having a first longitudinal side arranged so as to be rested on a bottom part of a said axial slot formed in any of the curved surface of the lower needle cylinder and in the curved surface of the upper needle cylinder; at least two heels which protrude transversely to a longitudinal extension of said laminar body on a second longitudinal side of the laminar body which lies opposite of said first side; needle arrangement means, provided at said laminar body, proximate to a first one of said ends for engagement with a needle, wherein a first one of said two heels is arranged on a movable portion of said laminar body which is movable with respect to a remaining part of said laminar body in a direction which is transverse with respect to the longitudinal extension of said laminar body, movement of said laminar body movable portion determining transfer of said first heel from an inactive position to an active position, and from an active position to an inactive position, said first heel being spaced from said first side of the laminar body more in said active position than in said inactive position, said first hell being constituted by the one of the said two heels that lies closest to the end of said laminar body provided with said means for engaging the needle, said movable portion of said laminar body comprising a portion which is elastically flexible, in a plane of arrangement of said laminar body, with respect to said remaining part of said laminar body, said first heel being arranged on said flexible portion.
