20080216720 | Embroidery Machine - An embroidery machine includes a sewing arm having an upper shaft for providing a driving force, a needle bar support case, which is assembled to a front portion of the sewing arm so as to be laterally movable, a needle bar provided in a needle bar support case, the needle bar having a needle at a lower end thereof and vertically carrying the needle using a rotation driving force of the upper shaft, and a presser foot, which is provided in the needle bar support case so as to be vertically movable, characterized in that each of the needle bar and the presser foot is operated by an individual drive mechanism. The presser foot is separately driven by its own drive source, independent of the drive source of the needle bar. | 09-11-2008 |
20110113998 | SEWING MACHINE - 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. | 05-19-2011 |
20110185957 | MULTI-NEEDLE SEWING MACHINE - A multi-needle sewing machine is disclosed that includes a needle-bar case that supports needle bars; a needle-bar case transfer mechanism that transfers the needle-bar case to place a predetermined needle bar to a needle drop position; a thread guide member that is movable up and down, the thread guide member being provided with thread guide sections spaced by a predetermined distance and that guide a plurality of threads; a plurality of thread inlets that are provided at the needle-bar case, each thread inlet being uniquely associated with one of the thread guide sections and that introduces the threads guided by the thread guide sections toward the needle bars; and a lifting/lowering mechanism that moves the thread guide member up and down during transfer of the needle-bar ease and the thread inlets such that the thread guide sections and the associated thread inlets maintain a constant distance therebetween. | 08-04-2011 |
