The machine comprises in combination: two side units (1, 3) each having its own fabric forming cylinder (1C, 3C) with a plurality of needles and needle operating elements (1F, 3F, A1-A8), the cylinders being parallel with each other and close together and, in an intermediate position between said two cylinders (1C, 3C), two rectilinear beds (11A, 11B) next to each other, each with its own needles and elements (17A, 17B, A9, A17) for operating the needles of said beds.
摘要:
An apparatus is disclosed for braiding fine denier yarns to form a braided suture product which includes a frame, and a main carrier support plate supported on the frame and having a pair of undulating guide channels intersecting each other for guiding a plurality of yarn carriers. A plurality of yarn carriers are supported on the main carrier support plate, and each supports a bobbin for dispensing fine denier yarn. A guiding system is provided for directing the yarn carriers over intersecting paths corresponding to the shape of said guide channels, with a first set of the carriers being directed in a first direction and a second set of the carriers being directed in the opposite direction. A take-up system is positioned above the yarn carriers to provide reception of the yarns in a common braiding zone while the yarn carriers are directed through the intersecting paths of the guide channels to form a braided sheath from the yarns. A take-up clutch system is provided for controlling the tension of the final braided product within predetermined ranges permits formation of a braided product of predetermined appearance. A method of producing the braided product on the invention apparatus is also disclosed.

The slide frame of the warp knitting machine is secured via a spacer element of light weight construction on the slide bar. The spacer means is in the form of a plurality of elongate plates which are resilient in the longitudinal direction of the slide frame or in the form of a single one piece perforated plate.
摘要:
A circular knitting machine, comprising a footing with a rotatable, vertical needle cylinder, axial slots on the outer lateral surface of the needle cylinder, that accommodate each a needle, a sub-needle arranged below each needle in a corresponding axial slot connected bilaterally to the needle and having a radial heel, the sub-needle being oscillatable on a radial plane of the needle cylinder, sub-needle actuation cams, for producing movement of the sub-needle along the axial slot to actuate the overlying needle.

摘要:
A linear knitting machine (1) comprising a loom, at least one needlebed (3) associated with the loom, a plurality of needles (4) sliding in the needlebed (3), means for feeding the needles (4) with a yarn for building a new stitch and knock-over means (8) cooperating with said needles (4) on the needlebed (3) and moving between a forward position, which occurs when the needle (4) is lifted, in which they act upon said stitch so as to keep it on the stem (5) of the needle (4), and a rear position, when the needle (4) gets down, in which they do not act upon the stitch. The machine (1) is characterized in that it further comprises holding means (15) fastened to the loom and discharging means (19), associated with the knock-over means (8), which can be engaged with said holding means (15) in forward position for discharging onto the loom the force generated by the knock-over means (8) when keeping the stitch, and which can be disengaged from the holding means (15) in rear position.
