  • Patent number: 10362988
    Abstract: A method for knitting a garment having a tubular form, including knitting at least one conductive textile electrode on a machine having N participating feeders and M needles. The method includes the steps of continuously knitting the tubular form with one or more flexible non-conductive yarns, and knitting the electrode integrally within the tubular form, using a conductive yarn, in addition to the non-conductive yarns. The conductive yarn is knitted in a float-loop form by knitting a stitch and skipping over y needles, as follows: repeatably knitting a line segment Lk, using feeder Fi and starting at needle D1; and knitting line segment Lk+1, using the next feeder and start stitching the first float-loop at needle D1+s where 0<s<y. The tubular form has a preconfigured 10 knitting density, wherein the electrode has a knitting density that is higher than the preconfigured knitting density of the tubular form.

  • Patent number: 7509820
    Abstract: Referring to a rehanging needle, the shaft is provided with a cutout that receives the tip of a rehanging spring. The cutout is divided into a first section and a second section, whereby the two sections have different depths. When a half stitch slides onto the rehanging spring, the spring tip can use the space due to the recessed second section and sink into said space, without the rehanging spring experiencing a permanent deformation. Consequently, it is possible for the half stitches to consistently and reliably slide up in order to set up the rehanging operation.

  • Patent number: 7469562
    Abstract: 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°.

  • Patent number: 7305855
    Abstract: 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.

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).

  • Patent number: 6792775
    Abstract: 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.

  • Patent number: 6510714
    Abstract: A latch needle (1) has a leaf spring (8, 8′) that is associated with the latch (4), that is disposed in the sawslot (3) and is held in corresponding bearing seats (14, 15) at the narrow sides or end walls (11, 12) defining the sawslot 3. Each bearing seat (14, 15) has a support surface (18) for the respective end of the spring, and at least one counterpart surface (21), with the respective end (16, 17) of the leaf spring (8) extending between these two surfaces and being held there. The axial or longitudinal play of the leaf spring (8, 8′) is so small that the leaf spring (8, 8′) cannot fall out of the space between the support surface (18) and the counterpart surface (21), even when it is deflected to a considerable extent. The leaf spring (8, 8′) is therefore held securely in the sawslot (3).

  • Publication number: 20020152774
    Abstract: The improved latch needle (1) is provided with a latch (5) having a latch shaft (11) with side surfaces (21, 22), which are divided into surface areas (23, 24) that are offset against each other and/or are arranged at an angle to each other. As a result, the thickness of latch (5) measured in the direction of its rotational axis (27) is slightly larger than the thickness in the shaft region (43), particularly at a location (45) in the area of transition from the latch shaft (11) to the latch spoon (16). On the other hand, the location (43)[sic] is close to the hook-side opening of the latch slot (6). By reducing the width, particularly in this region, the easy movement of latch (5) is ensured even if dust or dirt enter the latch slot (6) or are deposited on the side surfaces (21, 22).

  • Patent number: 6330814
    Abstract: 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.

  • Patent number: 6321578
    Abstract: 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.
