Abstract

The invention relates to a stem-crossing sewing control method, device and system. The method comprises the steps that whether a sewing material stem part is located at the front end of a sewing machine presser foot or not is determined; the sewing material is an elastic sewing material; when the feed dog is in a non-feeding state, a machine needle penetrates through the elastic sewing material and the sewing material stem part is located at the front end of a presser foot of the sewing machine, the presser foot is lifted to a preset height, so that the sewing material stem part enters the bottom of the lifted presser foot under the action of elastic force for sewing. By means of the sewing machine, the presser foot and the feed dog of the sewing machine cannot generate unfavorable blocking force on the stem portion of the sewing material, and the sewing effect that the stitch length is uniform is achieved.

Description

technical field [0001] The present application relates to the technical field of sewing machines, and in particular, to a control method, device and system for over-stemming sewing. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material, so that one or more layers of sewing material are interlaced or sewn together. The sewing machine can sew cotton, linen, silk, wool, man-made fibers and other fabrics, as well as leather, plastic, paper and other products. [0003] During the sewing process of the current sewing machine, when a stem material appears on the sewing material, the thickness of the stem portion of the sewing material changes. However, the sewing machine cannot judge the position of the stalk material in time. When over stalking and sewing thick materials, it continues to maintain the original state for sewing, resulting in uneven stitch spacing and sewing effect at the ...
