摘要:
Multi-needle quilting machine comprising at least a base, an introduction unit configured to feed at least a material to be quilted in a direction of feed and at least a stitching unit to make stitches on at least one material. The machine comprises a first stitching unit and at least a second stitching unit each provided with at least a row of needles with an oblong development along a respective longitudinal axis, at least one of either the first stitching unit or the second stitching unit being installed on at least one platform selectively translatable, with respect to the base, in a direction of movement substantially orthogonal to the direction of feed.

A guide member is moved in interlocked relation to a rotary member rotating about the axis of a needle bar, so that a string-shaped material paid out from a bobbin is guided to a needle drop position of a sewing needle. The bobbin having the string-shaped material wound thereon is supported by a support member that is rotatable generally about the axis of the needle bar and disposed over a machine table in such a manner as to not hamper movement of an embroidery frame. The bobbin can be positioned at a distance from a machine head; thus, bobbins of increased sizes can be used. The support member is controlled in orientation, by means of a drive source, in accordance with rotation of the rotary member. The bobbin itself revolves around the machine head, which allows the string-shaped material to be constantly appropriately guided to the needle drop position.

In a first shifting operation for shifting a sequin sewing device from an operative position to an evacuated position or in a second shifting operation for shifting the sequin sewing device from the operative position to the evacuated position, descending movement of a needle bar is inhibited by jumping the needle bar with a sewing machine maintained in an operating condition. Also, a jump code is inserted into embroidery data at a position where a shift is to be made from sequin sewing to ordinary sewing or from ordinary sewing to sequin sewing. Alternatively, the descending movement of the needle bar may be inhibited by reducing a rotation speed of the main machine shift with the machine maintained in the operating condition.

An embroidery machine can simultaneously embroider sewing objects having various shapes, including a flat object, an object having a shape of a usual processed cloth, an object having a shape of a cap, etc. The embroidery machine comprises a plurality of sewing heads grouped into at least two working groups, and the embroidering frames, each of which is arranged for one of the working groups. The embroidering frames have structures either identical to each other or different from each other. Therefore, one conventional embroidery machine can simultaneously embroider more than one kind of sewing objects, including at least two of a flat sewing object, a tubular sewing object, and a cap-shaped sewing object.
摘要:
A method for embroidering a fabric or article of clothing. A design is applied to a material using an application process such as screen-printing, transfer printing, ink jet printing or appliqué, and stitching is applied over one or more areas of the design in a density that permits design to remain visible through the stitching to give the appearance of a normally embroidered design using less stitches.
摘要:
A sewing machine including a head portion including a needle bar, the needle bar being for mounting a needle threaded with a needle thread; a principal shaft; a sewing machine motor for driving the needle bar via the principal shaft; a bed portion including a loop taker for taking a thread loop of the needle thread in cooperative operation with the needle; a loop taker drive shaft connected to move in association with the loop taker; a loop taker drive unit including a loop taker drive motor for driving the loop taker drive shaft independently of the principal shaft; a synchronization control unit for controlling at least one of the loop taker drive motor and the sewing machine drive motor so that the loop taker and the principal shaft rotate in synchronization; and an offset adjustment unit provided to the synchronization control unit and for adjusting an amount that the phase of the loop taker is offset from a reference phase offset amount preset for the loop taker with respect to the principal shaft.
摘要:
In this invention, a cloth frame moving device whereby the three operations of the movements and rotation of X and Y components can be detected with a three rotary pulse generator which is fitted to a recording sewing machine so that pulse trains generated from the above mentioned three pulse generator may be added to the pulse wave form in a positive or negative direction and a pulse generator for detecting the lateral amplitude of a machine needle bar. A device for detecting instructions on the starting and stopping of the machine are provided in the machine so that the pulse trains generated from these respective pulse generator may be recorded in turn in a magnetic carrier.
摘要:
A stitch frame actuating mechanism mountable on an ordinary linear sewing machine for the purpose of stitching cycloidal patterns and their modifications without using conventional pattern-cams in which a planetary gearing driven by a rotationgenerating means actuated by one of the reciprocating members of the sewing machine is connected to a stitch frame holder through a parallelogramic link to displace said stitch frame holder along a cycloidal curve.
摘要:
Sewing machine, here illustrated as a machine for simultaneously embroidering a plurality of pieces of goods with an identical pattern or for embroidering a plurality of identical patterns on a single piece of goods. The illustrative machine comprises a plurality of embroidering stations, a plurality of embroidering mechanisms each of which is disposed at a rsspective embroidering station, and means for traversing the goods relative to the mechanisms at the stations to embroider the goods in accordance with the pattern.
