摘要： In a single-cylinder circular knitting machine having two needle beds or needle-carrying structures (1,2), the lower structure (2) comprises a needle cylinder and the upper structure (1) penetrates for its major portion into the cylinder and has needle tricks (15) therein of arcuate shape with their center of curvature located on the same side as the cylinder, for accommodating arcuately bent latch needles (16). The needles (16) have their hooks and latches arranged on the convex side of the arcuate shape. They may have butts intended for controlling their movements, or be controlled by means of jacks. The upper needle-carrying structure (1) may advantageously be open at the center to allow the knitted fabric (25) to be pulled and/or discharged to the top. A machine of this type may have the same number of needles in both needle-carrying structures (1,2), even where the latter have small diameters, and a smaller height dimension than traditional needle cylinder and dial machines of equal diameter.

摘要： In a circular knitting machine of the type having two needle beds or needle-carrying structures (1,8) for knitting plain and purl stitches, the lower needle-carrying structure (1) comprises a cylinder and the upper needle-carrying structure (8) has a substantially bell-like shape and needle tricks (11) of arcuate shape for correspondingly arcuately bent needles (13). The arcuately bent needles (13) are controlled by selecting jacks (12), in turn controlled by cams (18) arranged around the substantially bell-like structure (8). Such a machine can have the same number of needles (3,13) on both needle-carrying structures (1,8), and accordingly, a higher fineness for a given diameter than traditional cylinder and dial machines. It also enables knitting loops to be transferred between all of the needles (3,13) in the two structures (1,8), ' both from the purl stitch side to the plain and from the plain stitch side to the purl, thus enabling the knitting of various types of rib pattern, such as 1:1, 2:2, etc., without requiring any jack replacement.

摘要： The invention provides a circular knitting machine, in particular a single or double cylinder hose knitting machine, wherein various operations, such as the advancement of the main drum (2), speed changing, needle selection, movement of the stitch-adjusting unit (3), etc. are controlled by an electronic programming unit instead of the traditional main chain. The electronic programming unit programmingly controls a series of electro-mechanical transducers, preferably solenoid valves and pneumatic or hydraulic cylinders (12, 23), which determine the required movements of the machine operational members (2, 3). The programming unit is operative at each revolution of the machine to receive drive pulses from a revolution transducer. A considerable constructional simplification and adaptability of the machine to different knitting programs is thus achieved.

摘要： In a single cylinder circular knitting machine having two needle beds or needle-carrying structures (1,2), for knitting plain and purl stitches, the upper needle-carrying structure (2) is arranged in the upper inner portion of the needle cylinder (3) and is made rigid therewith. It has needle tricks (16) of arcuate shape for corresponding arcuate needles (19), the center of curvature being located on the cylinder (3) side externally to the upper needle-carrying structure (2). The needles (16) are of the latch type, with the hook and latch being located on the convex side of the respective needles (16). The latter are controlled by means of cams (21,22) located substantially within the needle cylinder (3). In such a machine, the needle dial and related supporting and rotating means are totally absent, and it is possible to provide an equal number of needle tricks (4,16) in both needle-carrying structures (1,2).

摘要： To blow a yarn toward the needles and release it from the gripping device upon yarn feeding in a circular knitting machine, in particular a double cylinder one, a device is provided which is synchronized with each yarn feeding finger regardless of the number of feeds. The device comprises a control cam (31) provided with a boss (32) and rotated synchronically with the needle cylinder(s), an actuating cam (23) provided with two oppositely located notches (24) and connected to the control cam (31) through a normally disengaged coupling controlled by the machine program, and an actuating lever (18) which follows the profile of the actuating cam (23) and controls a valve (11) to cause it to engage with the control cam (31) and be operated by the boss (32) thereof to deliver pressurized airto the yarn feeding area. The valve (11) can be moved into the operative position by means of each yarn feeding finger associated with one feed.
