摘要:
To provide a needle bed for a circular knitting machine in which, an insert piece for forming a groove for slidably storing the knitting tool, the contact area between the knitting tool and the insert piece is reduced. A needle bed which is mountable to the circular knitting machine is configured to slidably store a knitting tool in a groove of which both side surfaces are formed by opposed plate surfaces of adjacent insert pieces 50 having a rectangular plate shape, wherein each insert piece 50 has a plurality of dimples 53 formed in a short-side direction X and a long-side direction Y on the plate surfaces.

In a winding control method and device for a circular knitting machine, in a position control mode in which control is performed such that winding is performed in a winding amount corresponding to position control data, a winding control portion (6) changes production amount data in response to a change in specific knitting data which affects a production amount of the knitted fabric during operation, of the knitting conditions, and sets the position control data corresponding to the winding amount of the knitted fabric such that the position control data changes in synchronization with the change in the production amount data.

An apparatus for controlling a knitting machine (10) includes an plurality of needle selecting devices (20) for selectively actuating knitting needles of a circular machine. Each of the needle selecting devices (20) is provided with a drive circuit (25) for driving a pattern finger and a shift register (26). Knitting data a is sequentially supplied from a controller (30) to the shift register (26) in one of the needle selecting devices and then serially from this shift register to the remaining needle selecting devices (20). At the time the transfer of the knitting data completes, the knitting data is latched and retained in each of the shift registers (26) and the drive circuit (25) is activated based on the retained knitting data.

A latch opener (11) comprises an opening section (1a,1b) for opening the closed latch of a knitting needle (7) and a holding section (2) for holding the opening section. The opening section is pivotally supported on the holding section (2) by means of a pivot pin (5) such that the opening section can move between an operational position (A), in which the latch is opened, and a non-operational position (B) in which the latch is not opened. At least one first magnet is secured to the opening section, and at least two magnets (4a,4b) are secured to the holding section (2). The magnet (4a) is secured to the holding section (2) so as to attract, in the operational position (A), the first magnet (3) secured to the opening section, and the magnet (4b) is secured to the holding section (2) so as to repel, in the non-operational position (B), the first magnet (3) secured to the opening section.
摘要:
A double knit circular knitting machine (20) has a first needle bed (24) in which transfer needles (26) are mounted and a second bed (21) in which ordinary needles (23) devoid of transfer function are mounted in a double density to that of the transfer needles (26) for knitting a high density fabric in any one of several predetermined patterns. The high density fabric is knitted by utilizing the transfer and ordinary needles (26,23) to form courses of stitch loops and, as dictated by the pattern, to transfer stitch loops from selected transfer needles (26) to correspondingly selected ordinary needles (23).
摘要:
A circular knitting machine (10) is provided and includes a cylinder (11), a gear ring (30) supporting and rotating the cylinder (11), a cam holder (14), a cam ring (15) supporting the cam holder (14) and a bed (20) supporting the cam ring (15) and the gear ring (30), and further including an oil collection system for controlling and collecting leaked oil to prevent the oil from staining the fabric being knit. The oil collection system includes a protrusion-free lower surface on said gear ring (30) that is inclined outwardly and downwardly, a chamber (23) in said bed (20) for containing machine parts, an oil collecting cavity (27) in the bed (20) underneath the inclined surface of the gear ring (30) and a reclamation pipe (29) for reclaiming collected oil.
摘要:
A circular knitting machine ( 20 ) comprises rotary needle cylinder, knitting needles, spring jacks, selector jacks (24) and a multi-tier electrically controlled needle selecting device ( 30 ). The needle selecting device ( 30 ) includes piezoelectric elements ( 32 ) and pattern fingers ( 33 ) for selecting and causing the selector jacks (24) control the movement of the needles ( 22 ) between welt, tuck and knit positions. A pre-pusher cam ( 34 ) is provided paritally to push the selector jacks (24) inwardly before these selector jacks are engaged by the pattern fingers ( 33 ) which increases the range of selection and permits increased speed in fine gauge knitting machines (24 gauge and higher) and which permits a reduction in the number of piezoelectric elements in coarse gauge machines and the inclusion of an interlock jacquard apparatus.
摘要:
A jacquard pattern control mechanism for a circular knitting machine (20) comprising a plurality of rocker bar supporting members (40) slidable in grooves (26) along which move knitting elements (27), a plurality of elongate rocker bars (44) pivotally mounted on the rocker bar supporting members (40) for movement about medial pivots, the opposite end portions of the rocker bars (44b,44c) being selectively movable between operative and inoperative positions and having magnetically attractable sections (44f,44g) thereon, and magnet attracting devices (50) operatively associated with the opposite end portions of the elongate rocker bars for selectively attracting one of the magnetically attractable sections at opposite ends of the rocker bars to pivot the rocker bars and selectively move the opposite end portions thereof to the other operative and inoperative positions. The magnetic attracting devices (50) comprise a permanent magnet and a pair of electromagnets (51,52) disposed on opposite sides of the permanent magnet and connected in series, the permanent magnet having an extension extending outwardly towards the rocker bars and having a pair of wing portions extending outwardly from the center portion of the extension, generally parallel to the rocker bar supporting members (40). The wing portions of the permanent magnet cooperate with the core parts of the electromagnets (51,52) in providing stronger magnetic fields for attraction of the magnetically attractable sections (44f,44g) of the rocker bars (44).
