Abstract:
A carriage which completes one course of knitting to the knitting end of a fabric is stopped. Knitting in a next course is performed when the carriage reverses its moving direction and re-starts its movement. Since the knitting yarn is not knitted to the fabric until a carrier brought by the carriage reaches a position of a knitting needle holding the stitch of the fabric at the knitting end, the knitting yarn existing in a feeding path between a yarn feeding mechanism and the carrier is excessively increased and a slack is generated. Since a distance between a yarn feeding port formed at a carrier's frontal end and the knitting needle at the fabric-knitting end is also reduced, the knitting yarn is further increased excessively. The further-excessively-increased knitting yarn is taken in by a yarn feeding means by reversing a servomotor, and further pulled in by a rewinding arm.
Abstract:
A needle selecting apparatus for a weft knitting machine capable of performing a needle selecting position locking function without moving a selecting jack forward and backward is provided. In the needle selecting apparatus, an initial position of the selecting jack is set at a welt position to ready for non-operation. And when a butt is pressed by a B presser of a carriage, the selecting jack comes into a locked condition by a locking member. The selecting jack is sunk into a needle groove in the locked condition and the butt of a knitting needle is also sunk into the needle groove to separate from a knitting cam. When a knitting position or tucking position is selected by a needle selection actuator, a selector is driven by a selector cam, and a tip of the selecting jack presses a contact portion of the selecting jack to move the selecting jack rightward. During the movement, the locking member is drawn to release the locked condition.
Abstract:
A fitting room (11) as a dressing room is adapted to have its entrance (12) opened and closed by drawing a curtain (14). The curtain is suspended from the tip ends of beam members of a curtain suspension apparatus (15) mounted on a ceiling plate (17). When closing the entrance (12), the curtain suspension apparatus (15) can deploy the curtain (14) in such a manner as to spread it outwardly relative to the fitting room (11) with respect to the entrance (12). The interior space closed with the curtain (14) can thus be enlarged when the curtain (14) is closed to use the fitting room (11). When the curtain (14) is opened, the space that was occupied by the curtain (14) when it was closed can be used for other purposes.
Abstract:
An object of the invention is to provide a simulation method and a simulation apparatus of the image of a twisted yarn capable of forming an image close to the actuality. When the images of twisted threads (1, 2) are inputted, abstracted models (3, 4) of the twisted yarns having a constant elliptical cross-section are obtained as shown in (b). A projected image (6) of the twisted yarns as shown in (c) is obtained when the models shown in (b) are viewed from the right side and one of two abstracted models (3, 4) located on the left side is concealed. The projected image (6) of the twisted yarns is formed by copying the images of the twisted yarns (1, 2) on to parts corresponding to the abstracted models (3, 4) of respective twisted yarns.
Abstract:
A weft knitting machine with a movable sinker device capable of preventing yarn from being worn caused by repeatedly striking the yarn with a sinker energized by a spring to push down knitting fabric, wherein a stroke to which a yarn locking part (2a) at the tip of a sinker plate (2) is moved to a tooth port (6) by the energization of the spring (4) is increased at a first stage shown in (a) and decreased at a second stage shown in (b), the stroke is limited in (b) by locking a holding locking part (12a) of a holding member (12) to the holding locking part (2d) of the sinker plate (2), and a stage is switched to a second stage at a knitting portion where the yarn locking part (2a) repeatedly strikes the yarn to prevent the yarn from being thinned and fluffed.
Abstract:
An object of the invention is to improve yarn feeding conditions to a knitting needle and improve a loop pressing function and a yarn holding function for end stitches in a flat knitting machine provided with a compound needle. In a top portion 12 of a loop presser 11 advancing to a tooth mouth 10, a knitting yarn holding portion for end stitches 13 and a loop presser portion 14 are formed. The knitting yarn holding portion for end stitches 13 hides a tongue 25a from the yarn 22 at a wall portion 15 above the knitting yarn holding portion for end stitches 13 so that the problem of yarn entanglement that the yarn 22 fed to a hook 24a of the compound needle 23 from a yarn feeding port 20 is surmounted on the tongue 25a may be solved. A pressing portion 16 below the knitting yarn holding portion for end stitches 13 presses the yarn 22. The knitting yarn holding portion for end stitches 13 holds the yarn 22 outside the end stitch by winding it around it. The loop presser portion 14 presses the yarn 22 during the knitting. While hiding the tongue 25a of the needle 23 of the end stitch at the wall portion 15, the yarn 22 can be guided into the hook 24a reliably by causing the loop presser portion 14 of another loop presser 11 to act.
Abstract:
An object of the invention is to obtain an intarsia pattern fabric which is not likely to cause yarn entanglement, eliminates the need for divided knitting, and provides good productivity even when a cylindrical knitting fabric is to be knitted. in a double bed flat knitting machine, a carriage and an intarsia carrier capable of knitting with two sets of cams are used to knit two courses of knitting fabric by moving a carriage six courses. An intarsia pattern is knitted at a front needle bed FB, and a knitting yarn between the intarsia carrier halted near a boundary and a knitting needle F is used to perform kick-back of the intarsia carrier by the third-course movement of the carriage. A back body is knitted while the yarn is hooked on an unused knitting needle F in a back needle bed BB. The sixth-course movement of the carriage releases a knitting yarn from the knitting beed F in the back needle bed BB while the back body is being knitted.
Abstract:
A method of knitting an inlaid fabric including a base knitting fabric portion and an inlay yarn and an inlaid fabric knitted by the method. The method comprises the step that the base knitting fabric portion is knitted; the step that inlay yarn holding loops are formed by retaining loops of the base knitting fabric portion retained by the needles on the first needle bed to the needles on the opposed second needle bed through a split knit process, whereby the loops are retained to the needles on both of the first and second needle beds; the step that the inlay yarn is made to run across the loops retained to the needles on the first and second needle beds; the step that the inlay yarn holding loops retained by the needles on the second needle bed are transferred to the needles on the first needle bed to be overlapped with the loops of the base knitting fabric portion; and the step that a yarn is fed to the needles of the first needle bed to form loops of the next course.
Abstract:
A sheet material 2 is cut with a round blade 10 and a notching blade 11. It is assumed that, in a straight section P1-P2-P3-P4, a distance between the end point P1 and the end point P2 is not shorter than a blade width W10 of the round blade 10, a distance between the end point P2 and the end point P3 and a distance between the end point P3 and the end point P4 are shorter than the blade width W10 and it is necessary to cut without cutting into a pattern piece indicated by shadow. A section between the end point P2 and the end point P3 can be cut without cutting into the pattern piece although overcut occurs on the end point P2 side, with the round blade 10 by aligning the leading edge thereof at the end point P3. A section between the end point P3 and the end point P4 is cut with the notching blade 11 because cutting with the round blade 10 causes a cut into the pattern piece at least from one of the end points.
Abstract:
A knitted fabric presser unit includes pressers corresponding to respective reciprocal directions and installed in a carriage. A first presser presses a knitted fabric when the carriage is being moved in a first knitting direction, during which a second presser is in a rest position. The first presser moves in conjunction with displacement in one direction of a sliding plate due to a follower engaged with a grooved cam. Similarly, the second presser moves in conjunction with displacement in another direction of the sliding plate due to a follower engaged with a grooved cam. Displacement of the sliding plate is caused by a rack engaged with a pinion fixed at a rotation axis of a motor. Movement traces of the first presser and the second presser are determined so that the two pressers are prevented from interfering with each other on movement thereof between a respective pressing and rest positions.
