Abstract: A multi-needle sewing machine includes a plurality of needle bars having lower ends to which needles are attached, respectively, a needle bar selecting unit selectively switching one of the needle bars to a needle location, a stitch number obtaining unit and an allotting unit. An embroidery pattern including a plurality of partial patterns is sewn by the use of needle threads of colors differing per partial pattern, while the needle bars are selectively switched. The stitch number obtaining unit obtains the number of stitches necessary for sewing the partial patterns for every partial pattern. The allotting unit allots the needle threads to the needle bars so that the needle bars are prevented from being one-sided in the number of stitches, based on the obtained number of stitches, in order that one of the needle bars to be used for the sewing of each partial pattern may be determined.

Abstract: Sewing data of multiple sewing targets stored in RAM of a sewing sequence determining apparatus is acquired. Permutations or combinations of the sewing targets are created as sewing sequence candidates. A number of needle bars N provided at a multi-needle sewing machine is acquired. An optimal thread replacement count is initialized. A thread replacement count is calculated for each of sewing sequence candidates, in the case where sewing operations are carried out by the multi-needle sewing machine equipped with N needle bars on the sewing targets in accordance with the sewing sequence candidates. A sewing sequence candidate of the fewest thread replacement count is determined to be an optimal sewing sequence candidate. The optimal sewing sequence candidate is displayed on a liquid crystal display and announced. Determination of sewing sequences at the time of carrying out sewing operations with respect to multiple sewing targets is easily achieved.

Abstract: An embroidery data creation apparatus and program acquires closed region data of a target unit pattern with a sewing order specified by a unit pattern counter and position data of a sewing endpoint of a preceding unit pattern to be sewn immediately prior to this target unit pattern. Based on the closed region data and the position data of the sewing endpoint, it is determined whether a sewing endpoint of the preceding unit pattern is present in a sewing region of the target unit pattern. If it is determined that the sewing endpoint is present in the sewing region of the target unit pattern, thread-cutting operation at this sewing endpoint is set not to be performed. On the other hand, if it is determined that the sewing endpoint is not present in the sewing region of the target unit pattern, thread-cutting operation at this sewing endpoint is set to be performed or withheld.

Abstract: A multi-needle type embroidery sewing machine and a computer-readable storage medium including a computer program for the multi-needle type embroidery sewing machine that may enable convenient selection and replacement of thread information. The multi-needle type embroidery sewing machine may include a plurality of needle bars, a needle bar thread information storage device, a needle bar selection device that enables the selection of a suite of needle bars selected from the plurality of needle bars, and a control device for changing needle bar thread information that corresponds to a needle bar in the selected suite of needle bars.

Abstract: When a user specifies, as an embroidery sewing condition, an embroidery pattern that can be sewn with thread spools set for needle bars, embroidery data on an embroidery pattern and needle bar thread information on a thread set for a needle bar are read and stored in a RAM. Embroidery thread information included in embroidery data is read out in a sequential order, and embroidery thread information and specified thread information are compared with each other. An embroidery pattern having embroidery data of which all of the embroidery thread information is coincident with the specified thread information is extracted as an embroidery pattern that satisfies the embroidery sewing condition. The extracted embroidery pattern is then displayed on a liquid crystal display.
