摘要:
A circular hosiery knitting machine with high stitch forming precision and high operating versatility. The machine (1, 1a) comprises a supporting structure (2, 2a) and a needle cylinder (4, 4a) which is oriented so that its axis (3, 3a) is substantially vertical and is provided, on its lateral surface, with a plurality of axial slots (5, 5a), each of which accommodates a needle (6, 6a) which can be actuated with a reciprocating motion along the corresponding axial slot (5, 5a). A sinker ring (7, 7a) is arranged around the upper end of the needle cylinder (4, 4a), is coaxial to the needle cylinder (4, 4a) and is provided with a plurality of radial slots (8, 8a), each of which accommodates a sinker (9, 9a), which can move with a reciprocating motion along the corresponding radial slot (8, 8a). Each sinker (9, 9a) is provided with a heel (10, 10a) which protrudes upward from the corresponding radial slot (8, 8a) and can engage at least one path defined in a sinker cover (12, 12a), which faces in an upper region the sinker ring (7, 7a). The needle cylinder (4, 4a) is actuatable with a rotary motion about its own axis (3, 3a) with respect to the supporting structure (2, 2a) and the sinker cover (12, 12a). The machine (1, la) comprises means (13, 13a) for adjusting the position of the sinker cover (12, 12a) on a plane which is substantially perpendicular to the axis (3, 3a) of the needle cylinder (4, 4a) with respect to the supporting structure (2, 2a) and means (14, 14a) for varying the angular position of the sinker cover (12, 12a) around the axis (3, 3a) of the needle cylinder (4, 4a) with respect to the supporting structure (2, 2a).

The invention relates to a circular jersey knitting machine for production of plush fabric consisting of at least one knitting system with radially movable sinkers (8) fitted with a belly (83) for lapping the ground thread (126) and a nib (84) for lapping a plush thread (127), while these sinkers (8) are controlled by cams with radially immovable needle cams (91) and/or their parts and radially movable tensioners (92) of plush loops for tensioning the plush loops by a radial movement towards the centre of the machine and the sinkers' (8) nib (84) while drawing-out the sinker (8) towards the centre of the machine plugs into previously formed plush loops, whereas the machine further consists of knitting means, which are arranged in a cylinder and they are controlled by a cylinder cam system with a lifting and drawing-down part of a cam channel. The invention consists in that the radially immovable needle cam (91) is fitted with a part (913) for drawing-out the sinkers (8) before the tensioner (92) of plush loops, which is situated in the direction of bed (2, 3) rotation behind the point of sinking the ground thread (126) over the edge of the sinker (8) belly (83), while this part (913) is followed by a front end (921) of the tensioner (92) of plush loops and the part (913) of the radially immovable needle cam (91) is less steep than the front end (921) of the tensioner (92) of plush loops and/or the back end (927) of the tensioner (92) of plush loops slants in the direction of drawing-down the sinkers (8), which exhibits lower steepness than the steepness of the next following part (914) of the radially immovable needle cam (91) for drawing-down the sinkers (8) behind the tensioner (92) of plush loops.The invention relates also to use of this principle in cylinder cam system. The invention further relates to a thread guide (11) on the circular jersey knitting machine for plush fabric production. Further the invention relates to provision of adjustability of proper mutual position of cam channels controlling the movement of the sinkers (8) and the needles (6).
摘要:
A needle-holding element (1 ) for circular knitting machines, having a structure as a hollow solid of rotation developing around a central axis (X) and configured for rotating and for supporting a plurality of needles (N) moving so as to produce a knitted fabric; the needle-holding element has at least one working surface (2) shaped as a surface of rotation obtained through the rotation of a portion of generating straight line (GC; GP) around the central axis; on the working surface a plurality of needle seats (3) is defined, placed one beside the other and arranged circumferentially or radially around the central axis, wherein each needle seat movably houses at least a portion of at least one respective needle (N). At least one needle seat has at least a first length (5) has a longitudinal development, on the working surface (2), inclined with respect to the generating straight line (GC; GP).

A sinker cam ring for a circular knitting machine comprises a plurality of sinker cam segments arranged edge-to-edge to form the sinker cam ring, each sinker cam segment defining a portion of a sinker cam track that defines sinker-advancing and sinker-retracting surfaces. Breaks between adjacent sinker cam segments are located in linear portions of at least one of the sinker-advancing surfaces and sinker-retracting surfaces where substantially only frictional forces act on the sinkers, and thus where radial acceleration of the sinkers caused by the cam surfaces is substantially zero. The breaks for a given sinker cam segment can be circumferentially staggered relative to each other.

摘要:
Sinker cam segments in a circular knitting machine are located with respect to the generally radial direction by a generally radially inwardly facing location surface disposed radially outward of the segments. Each segment's radially outer end defines a contact region that abuts the locating surface. The contact region can be complementary surface contour to that of the locating surface, or a pair of discrete, spaced contact points protruding out from the radially outer end of the segment. The contact region is a reference for positioning the sinker cam segment with respect to the generally radial direction.
