Abstract

An apparatus for processing sets of sewing data each set of which is needed to control a sewing machine to sew, on a work sheet, a corresponding one of sewing patterns with a corresponding one of sewing threads, the each set of sewing data including a set of designating data designating the corresponding one sewing thread, the apparatus including a data obtaining device which obtains the sets of sewing data which are needed to control the sewing machine to sew the sewing patterns in a predetermined order, and a changing device for, when the sewing patterns include at least one overlapping-pattern group consisting of at least two overlapping patterns which overlap each other, changing the predetermined order to a changed order such that an order of sewing of the overlapping patterns in relation with each other in the predetermined order is maintained in the changed order and such that a number of sewing-thread changes needed to sew the sewing patterns in the changed order is smaller than a number of sewing-thread changes needed to sew the sewing patterns in the predetermined order.

Dependent claims

An apparatus for processing a plurality of sets of sewing data, each set of which is needed to control a sewing machine to sew, on a work sheet, a corresponding one of a plurality of sewing patterns with a corresponding one of a plurality of sewing threads, said each set of sewing data including a set of designating data designating said corresponding one sewing thread, the apparatus comprising:

a data obtaining device which obtains said sets of sewing data which are needed to control the sewing machine to sew said sewing patterns in a predetermined order;
searching means for searching said sewing patterns for finding at least one overlapping-pattern group consisting of a plurality of overlapping patterns which overlap each other;
and
changing means for, when said sewing patterns include said at least one overlapping-pattern group, changing said predetermined order to a changed order such that an order of sewing of said overlapping patterns in relation with each other in said predetermined order is maintained in said changed order and such that a number of sewing-thread changes needed to sew said sewing patterns in said changed order is smaller than a number of sewing-thread changes needed to sew said sewing patterns in said predetermined order.

a data obtaining device which obtains said sets of sewing data which are needed to control the sewing machine to sew said sewing patterns in a predetermined order;
searching means for searching said sewing patterns for finding a first non-overlapping-pattern group consisting of a plurality of non-overlapping patterns which correspond to at least two sets of sewing data including respective sets of designating data commonly designating a first one of said sewing threads and which do not overlap each other;
and
changing means for changing said predetermined order to a changed order in which said non-overlapping patterns of said first non-overlapping-pattern group are consecutively sewn with said first sewing thread.
