  • Publication number: 20090301138
    Abstract: A knitting system (6) wherein said system causes a rocker guide (23) to move the holding-down and knock-over sinker 5 as a function of the longitudinal position of the knitting needle (4). Consequently, the pivoting movement of the holding-down and knock-over sinker (5) is forced to follow the back-and-forth linear movement of the knitting needle (4). A single box cam is sufficient for controlling this knitting system (6). In any event, it is only necessary to allocate box cams to the knitting needles (4). The holding-down and knock-over sinkers (5) do not require dedicated drives and box cams.

  • Publication number: 20090249836
    Abstract: A sinker set comprising a coulier sinker (11) and a plush sinker (12). The sinkers (11, 12) can be moved together in a direction transverse to a knitting needle (2). The sinkers have spaced apart edges for the accommodation of stitches. In order to adjust the distance between these edges, the sinkers (11, 12) can be moved relative toward each other in the driving-out direction of the needle. To do so, they have spaced apart guiding edges (17, 18; 27, 29, 30) that are in contact with various support surfaces or guiding surfaces (20, 22; 26, 32, 33).

  • Publication number: 20090126410
    Abstract: Proposed is a sinker (2) provided with a region (23) of reduced thickness on its working part (9). As a result, a clearance space is created on at least one side of the sinker (2). This clearance space makes it possible to reduce the distance between the sinker (2) and the latch needle (3) or to reduce the wear between these two elements. The clearance space furthermore does not change the distance between the sinker and the latch needle on the other side of the sinker. The sinker (2) according to the invention preferably has a clearance space on both sides, so that this sinker can be used in circular knitting machines which are designed for both rotational directions.

  • Patent number: 7533546
    Abstract: A system component (1), such as, for example a knitting machine needle (2), intended for a loop-forming machine has in its foot (8) at least one cutout (14) that is set up to accommodate a section of a holder (17). This holder can be clipped into the cutout in order to hold several such system components in a pre-specified sequence and at a lateral distance and in alignment with respect to each other. The systems components, which are thus temporarily connected to each other, can be handled as a unit and, in this manner, can be removed from the bed (5), can be treated, for example be cleaned, and can be replaced in the same sequence and alignment in the bed (5).

  • Patent number: 7493780
    Abstract: The knitting method in accordance with the invention is based on simple knitting tools without means for closing a thread-receiving space that is created by a simple cutout configured as a stitch support shoulder. In the simplest case, the stitch is formed by a simple back-and-forth movement of two knitting tools relative to each other, whereby said knitting tools can be arranged approximately at a right angle with respect to each and can be alternately pierced through each other. In so doing, the taken up thread is pushed through the half stitch respectively carried by the other knitting tool. The knitting method is based on simple and sturdy tools that are minimally susceptible to wear. Considering the manufacture of left-left knitted goods, this method permits, in addition, a significant increase in productivity compared with conventional machines while, at the same time, featuring greater simplicity of the knitting process and of the knitting tools.

  • Publication number: 20080271497
    Abstract: A knitting needle designed specifically for achieving particularly fine divisions, or another knitting tool (2), has a narrower working section (4) and a wider support section (5), whereby the support section (5) is provided with a positioning means (11), for example, having the form of a slit (12) or having the form of a rib (32). The knitting tool (2) is associated with a fixing means (29) in the form of a projection (17) or a groove (33) on the side of the bar (1). Due to this measure, the support sections (5) of the knitting tools (2) may be arranged—in close proximity to each other, in contact with or at a minimal distance from each other—on the bar (1), so that a maximum cross-section is available for configuring the support section (5). This provides strong stability for the knitting tools (2)—even in cases of extremely fine divisions—and, at the same time, provides precise alignment and avoids division errors.

  • Publication number: 20080271496
    Abstract: For longitudinal shifting, a needle in accordance with the invention is provided with a longitudinal slit 14 that is disposed to accommodate a bearing element (19), for example, having the form of a strip (20). Whereas known needles are set in a guide channel and thus are held or guided between two guide flanks, the needle in accordance with the invention extends around a strip (20) and is guided on said strip. Thus, the needle is guided on two surfaces of the guide element (19) and the strip (20), respectively, said surfaces facing away from each other. The support section (4) and the bearing element (19) form a highly precise positioning or guide device.

  • Publication number: 20080105577
    Abstract: A needle-holding device (1) suitable in particular as a package comprises a flat needle carrier section (4) and an adjoining section that has a clamping lip (5) that is resiliently biased against the needle carrier section (4). The clamping lip (5) reaches around the stitch-forming sections of the needles (2) which are held lying next to each in contact with each other on the needle carrier section (4). The resiliently yielding clamping lip (5) permits the insertion and the pull-out of one, several or of all the needles (2).

  • Patent number: 7334436
    Abstract: A system component (1) for a knitting system is composed of a body (3) with butt (18), which projects outward from the narrow side (16) of the body (3). According to a first advantageous embodiment of the invention, the butt (18) is positioned inclined or at an angle to the body (3). A corresponding bending line extends in longitudinal or movement direction of the body (3). The angle (?) is thus defined in an imaginary plane (E) that intersects the body (3) in transverse direction. As a result of this measure, the butt (18) can also be adjusted relatively precisely at a right angle to the cam movement if the system component (1) along with it the body (3) is arranged somewhat inclined inside a corresponding guide slot (4) of a bed (5), wherein the angle ? then compensates for the tilting. A line-type contact between the butt (18) and the guide track (7) is achieved, which reduces wear.

  • Patent number: 7266978
    Abstract: A knitting tool which is suitable for embodying both large and small loops has two needles (6, 7), disposed coaxially to one another, whose hooks are oriented identically. The hook of the larger needle (6) is split in two in the middle and comprises hook halves. The finer needle (7) can be driven between the two hook halves upon spreading of the two hook halves apart from one another. For selectively closing the hooks, a slide is provided, which can be brought into engagement both with the tip of the fine needle and with the tip of the coarser needle. To raise and lower the slide to the various positions of the hook tips relative to the needle back, a sliding control block may be provided. The sliding control block may be embodied on the coarse needle and the fine needle (7).

  • Patent number: 7047769
    Abstract: In an improved loop-forming system (1), in particular for compound needles (2), the compound needle during the knitting operation is moved along a nonlinear path. Depending on the embodiment, this path may be a loop, may include a loop, or maybe embodied without a loop. This is achieved by superimposing a transverse motion on the reciprocating needle motion; the transverse motion may be controlled for instance by a pivotably supported sinker, which is disposed in the needle track and defines the pivoting orientation of the compound needle (2).
