Publication number: 20090301138Abstract: 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.Type: ApplicationFiled: June 2, 2009Publication date: December 10, 2009Applicant: GROZ-BECKERT KGInventor: Uwe Stingel

Patent number: 7614255Abstract: The cutting needle (1) according to the invention is, for example, a latch needle and has a knife element (11) secured to the shank (2). The knife element (11) defines a cutting edge (18) which projects obliquely upward from the shank. The knife element (11) is arranged externally of the range of motion of the latch (4) and cuts open a loop situated on the shank when it is overdriven outward. The knife element (11) is made, for example, of a suitable spring steel and is held unremovably on the shank (2).Type: GrantFiled: April 6, 2005Date of Patent: November 10, 2009Assignee: Groz-Beckert KGInventors: Bob Hagens, Uwe Stingel, Eckhard Fehrenbacher

Publication number: 20090249836Abstract: 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).Type: ApplicationFiled: April 7, 2009Publication date: October 8, 2009Applicant: GROZ-BECKERT KGInventor: Uwe Stingel

Publication number: 20090126410Abstract: 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.Type: ApplicationFiled: November 21, 2007Publication date: May 21, 2009Applicant: GROZOZ-BECKERT KGInventors: Bob Hagens, Uwe Stingel

Patent number: 7533546Abstract: 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).Type: GrantFiled: February 1, 2007Date of Patent: May 19, 2009Assignee: Groz-Beckert KGInventor: Uwe Stingel

Patent number: 7493780Abstract: 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.Type: GrantFiled: August 13, 2007Date of Patent: February 24, 2009Assignee: Groz-Beckert KGInventors: Uwe Stingel, Manfred Sauter

Publication number: 20080271497Abstract: 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.Type: ApplicationFiled: May 5, 2008Publication date: November 6, 2008Applicant: GROZ-BECKERT KGInventors: Eric Jurgens, Andreas Dietz, Uwe Stingel, Torsten Butz, Klaus Kirchmair, Eckhard Fehrenbacher

Publication number: 20080271496Abstract: 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.Type: ApplicationFiled: May 5, 2008Publication date: November 6, 2008Applicant: GROZ-BECKERT KGInventor: Uwe Stingel

Publication number: 20080105577Abstract: 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).Type: ApplicationFiled: November 6, 2007Publication date: May 8, 2008Applicant: Groz-Beckert KGInventors: Uwe Stingel, Johannes Bruske, Hans-Joachim Halamoda

Patent number: 7334436Abstract: 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.Type: GrantFiled: December 21, 2006Date of Patent: February 26, 2008Assignee: Groz-Beckert KGInventors: Uwe Stingel, Eckhard Fehrenbacher, Manfred Sauter
