摘要： In a buttonhole sewing machine, a sewing mechanism and a feed bracket are controlled to form a buttonhole defined by settings, such as zigzag stitch length, zigzag pitch, bar-tack length, bar-tack pitch, and cutter space. The buttonhole can be set on the operation panel and changed to various shapes by changing the above settings. In particular, the left and right zigzag stitch widths can be set differently, and the front and rear bar-tack lengths can be also set differently. Thus, the balance of the buttonhole can be finely adjusted.

摘要： A pattern sensor installed in a sewing machine for sensing patterns on two opposing sheets of cloth so that the patterns on the separate cloths are correctly aligned while sewing. The sensor is composed of a sensor head disposed between the two sheets of cloth, a light source, a light receiver, two light conduits including bundles of thin optical fibers, and a reflector which is composed of two prisms provided in the sensor head. The light emitted from the light source is transmitted via separate conduits and respectively enters the prisms. One beam is reflected upward toward the upper cloth, and the other is reflected downward toward the lower cloth for sensing the patterns. The light reflected on each cloth returns to the light receiver via the reverse route to be processed as a pattern signal.

摘要： A pattern-matching sewing machine that constantly samples photo-intensity data during calculation of a mismatch distance and during adjustment of the feeding mechanism based on the calculated mismatch distance. When the adjustment is finished, a new mismatch-distance calculation is quickly started, not by waiting for sampling new photo-intensity data of a predetermined number, but by using photo-intensity data of the predetermined number including the data thus sampled during the previous calculation and adjustment, and the previously stored data which have been used in the previous calculation.

摘要： A pattern-matching sewing machine having a feed-correcting means for accurately adjusting feed amount using a correction factor with three values which are set according to various sewing conditions such as species of cloths and a speed of a main motor. When the feed amount for pattern matching is calculated based on only a mismatch distance detected by a photo-sensor, the accurate pattern matching is not achieved due to the various sewing conditions. Therefore, the feed-correcting means selects the optimum one of the three values to accurately correct the feed amount for a good pattern matching.

摘要： A buttonhole forming apparatus includes a cutter, a cutter driving mechanism, and a needle plate. The needle plate has a needle plate base to hold a work cloth thereon and a pair of cutter guides in a recess to guide an edge of the cutter therein. The cutter guides are made of hard material on the inside and rubber on the outside. The hard material can be moved outward by the resilience of the rubber. The width of the cutter hole defined between the cutter guides is set as small as possible so that the cutter does not force the work cloth into the cutter hole when it is lowered where it remains clogged. When the cutter is gradually lowered, the edge of the cutter or a part of the work cloth to be cut makes contact with the tapered portions of the cutter guides, and the rubber is deformed to move the cutter guides outward. Thus, the cutting into the work cloth can be done as the width of the cutter is gradually enlarged, resulting in the formation of appropriate buttonholes without any interruption because the work cloth becomes clogged in the cutter hole.
摘要翻译：扣眼形成装置包括切割器，切割器驱动机构和针板。针板具有用于将工布保持在其上的针板底座和在凹部中的一对切割器引导件，以引导切割器的边缘。刀具导轨由内侧的硬质材料制成，外侧由橡胶制成。硬质材料可以通过橡胶的弹性向外移动。刀具导轨之间限定的刀具孔的宽度设置得尽可能小，以便当刀具下降并保持堵塞时，刀具不会迫使工布进入刀具孔。当切割器逐渐降低时，切割器的边缘或待切割的工布的一部分与切割器引导件的锥形部分接触，并且橡胶变形以将切割器向外移动。因此，随着切割器的宽度逐渐扩大，可以进行切入工作，从而形成适当的纽扣孔而不会中断，因为工布在切割器孔中堵塞。
