Sewing machine for long-striped ribbon

Abstract

The present invention provides a sewing machine for sewing a tape, which has a fabric blocking device, a fabric blocking device that sequentially transports and feeds a plurality of fabrics while theside sequentially transports a plurality of fabrics, and the fabric is continuously fed and fed by the sewing portion on the side edges of the plurality of fabrics. In the case where the sewing fabricterminating end portion of the preceding fabric reaches the predetermined tape cutting position, the fabric portion that protrudes toward the downstream side in the sewing proceeding direction of thetape sewn portion in the sewing start end portion of the succeeding fabric can be partially avoided. With the tape cutting position of the tape cutting device or the position on the upstream side ofthe tape advancing direction from the tape cutting position, it is possible to avoid a disadvantageous situation in which the portion of the succeeding fabric is unnecessarily cut, and so that the tape is not worn. The waste is generated automatically and accurately.

Description

technical field [0001] The present invention relates to a long strip seam used when, for example, long strips such as lace or flat rubber are overlapped with legs of cut fabrics such as shorts or swimwear. sewing machine. Background technique [0002] like Figure 7 As shown, generally, a curved special-shaped cut fabric W is used for the side edge portions We, We of both legs such as shorts or a swimsuit. and, if Figure 8 As shown, long strips T, T such as drawstrings or flat rubber are sewn on the curved side edges We, We as the legs of the cut fabric W, and then the whole cut fabric W is folded in half and side-sewn. By forming the circumference of the abdomen, a predetermined sewn product such as shorts or a swimsuit is produced. [0003] Generally speaking, if Figure 9 As shown, when making the above-mentioned sewn products, a plurality of cut fabrics, that is, the preceding fabric W1 and the follow-up fabric W2 are continuously placed on the needle plate 1 of the...

Problems solved by technology

[0004] However, in this case, there is a problem that in order to cut the sewn strips, manual work with scissors or the like is required, and the sewing work must be temporarily interrupted every time, so the efficiency of the sewing work tends to deteriorate and the productivity decreases. , and production costs increase, and the use of scissors, etc. is also easy to damage the fabric
