Patent number: 7469562Abstract: In order to reduce the impact speed of a latch (4) of a needle (1) in back position by reducing the acceleration effect originating from a half stitch (19), the upward jaw slope (8) of the needle (1) is subdivided into different regions. A first section (12) ascends at a relatively large acute angle ? of, for example, up to 20°, preferably 16°. Just after the half stitch (19) has contacted the inside (14) of the latch (4), said half stitch arrives on a second section (16) of the upward jaw slope (8). The second section (16) is a straight section which ascends at a smaller acute angle ? of, for example, only 14° or less. Consequently, an acceleration effect from the half stitch (19) on the latch (4) is avoided over a wide pivot range of said latch. Preferably, this acceleration-free pivot range is at least 90°, preferably greater than 110°.Type: GrantFiled: November 8, 2007Date of Patent: December 30, 2008Assignee: Groz-Beckert KGInventors: Albert Bausch, Jorg Sauter

Patent number: 7305855Abstract: The machine knitting needle of the invention, beginning at its hook (3), between the hook (3) and its latch bearing (9), has a convex or at least not concave shank contour, which defines the inner hook contour and on one end (18) adjoins the concave inner hook contour directly. It is attained as a result that the elevation angle which a yarn (23), located in the hook (3), must overcome if it is to slide on the shank does not increase at any point along the inner contour (17). Preferably, it even decreases steadily. It thus has its maximum value inside a space which is defined on the one hand by the inner hook contour (15) and on the other by a plumb line (L) or (L1) which is dropped, from the hook tip (12) or its tapering portion (11), onto the needle back (16), or if the needle back is not oriented parallel to the direction of motion of the machine knitting needle, onto the arrow that defines the direction of motion.Type: GrantFiled: September 21, 2006Date of Patent: December 11, 2007Assignee: Groz-Beckert KGInventors: Johannes Bruske, Holger Cebulla

Patent number: 7272958Abstract: A novel latch needle has a sawslot (11) which is provided with facets or surfaces (22, 25) both at its frontal and its rearward end surfaces (18, 19). The surfaces (22, 25) are preferably parallel to one another and are oriented perpendicularly to the direction of length (L) of the shank. By virtue of this arrangement the surfaces are so oriented that the latch (6), as it opens or closes, pushes any dirt past the respective surfaces through the sawslot (11) and thus an accumulation and compacting of dirt cushions on the noted surfaces is avoided. Generally stated, the sawslot (11), particularly in the region of its end surfaces (18, 19) is thus void of any surface regions which represent an obstacle to the opening or closing latch (6).Type: GrantFiled: June 9, 2006Date of Patent: September 25, 2007Assignee: Groz-Beckert KGInventors: Eckhard Fehrenbacher, Uwe Hennig

Patent number: 7191620Abstract: The starting point of a new concept in a latch needle (1) is an attachment of the latch spring (22) in the sawslot (9) of the latch needle from the side of the needle back (7). For this purpose the latch needle (1) has spring-supporting pockets (19, 21) accessible from the needle back (7) or other structures adapted to receive the ends (25, 26) of the latch spring (22). The spring-supporting pockets (19, 21) are closed toward the needle back (7) at least to such an extent that the ends (25, 26) of the latch spring (22) are held in a form-locking, or at least in a captive manner in the spring-supporting pockets (19, 21). Such a latch needle has a reduced tolerance sensitivity during manufacture. The described needle concept makes possible further improvements which contribute to the operational safety and service life of the latch needle.Type: GrantFiled: October 5, 2005Date of Patent: March 20, 2007Assignee: Groz-Beckert KGInventors: Eric Jürgens, Andreas Dietz, Wolfgang Schmoll

Patent number: 6792775Abstract: A latch needle (1) has a latch spring (19), which assumes the width of the latch slit (5) in the vicinity of the latch seating (18). However, the latch spring (19) is embodied to be narrower on both sides of this section (25). By means of this, premature wear of the latch or spring in the area of the latch seating device (18) is counteracted on the one hand as is, on the other, the obstruction of the latch slit (5) by dust or dirt. The narrower sections (26, 27) of the latch spring (19) define a passage together with the inner face (8, 9) of the slit walls (6, 7), through which foreign bodies, such as fiber remnants, dust or the like can be conveyed from the upper needle side (11) in the direction toward the needle back (12). In contrast to conventional latch needles, needles (1) of this type of construction show reduced wear, a reduced susceptibility to becoming soiled, and therefore increased dependability.Type: GrantFiled: July 1, 2003Date of Patent: September 21, 2004Assignee: Groz-Beckert KGInventor: Zhiyong Wang

Patent number: 6330814Abstract: A circular knitted double fabric having an inner and outer layers which are basically separated from each other. At first group of yarn feeder knitting only by dial needles is done, while at second group of yarn feeder knitting only by cylinder needles is done. A stitching between the inner and outer layers by using both of the dial and cylinder needles is done along a closed outline of a garment. A cutting of the fabric along the closed outline is done in such a manner that the stitched parts are, at least partially left. As a result, a cutting of the fabric along the closed outline allows a garment to be separated from the fabric, which fabric has a front and back bodies, which are along its outline firmly connected with each other by the stitched parts.Type: GrantFiled: July 14, 2000Date of Patent: December 18, 2001Assignee: Kabushiki Kaisha Miyake Design JimushoInventor: Toshio Fujiwara

Patent number: 6321578Abstract: A method for creating an opening in tubular knitted fabric articles on a machine including a needle cam mounted for reciprocal movement between first and second vertically-spaced positions. In the first position the needle cam lowers successive needles to a position where the loop of yarn is released from a selected loop-forming needle and transferred to a transfer needle. In the second position the needle cam lowers successive needles to a position where the loop of yarn is transferred to a transfer needle adjacent the selected loop forming needle without being released from the selected loop-forming needle to thereby form a no-run stitch in the knitted fabric. A needle is selected from which a loop is to be transferred and the loop is enlarged on the selected needle by deflecting the loop out of the vertical plane of the selected needle laterally into the vertical plane of an adjacent needle while the adjacent needle is in a lowered, non-interfering position relative to the deflected loop.Type: GrantFiled: February 28, 2001Date of Patent: November 27, 2001Inventor: Francesco Gavagnin Apollonio
