摘要： In stitching operation with an electronic sewing machine storing a plurality of stitch control data, a fabric feeding amount for a specific pattern composed of densely arranged zigzag stitches is automatically controlled in a selective one of normal mode and alternate mode. The fabric feeding amount is usually controlled in the normal mode whereby a fabric feeding amount of a predetermined value or a manually selected value is constantly applied to every stitch of the pattern. The normal feed control mode is switched to the alternate feed control mode when the operator selects a fabric feeding amount smaller than a predetermined critical value, in which case the selected pattern composed of densely arranged zigzag stitches is produced with the fabric being fed in an amount double the selected value each time an alternate one of the zigzag stitches is produced. In the alternate feed control mode, a fabric feeding amount to be applied to the first stitch of the pattern is zero or of a value double the selected amount, which is determined depending upon the shape of the pattern and the needle position at the first stitch of the pattern.
摘要翻译：在使用存储多个针迹控制数据的电子缝纫机进行缝合操作时，以通常模式和交替模式的选择性自动地控制由密集布置的之字形针迹组成的特定图案的织物进给量。织物进给量通常被控制在正常模式，由此对图案的每个针迹不断地施加预定值或手动选择值的织物进给量。当操作员选择小于预定临界值的织物进给量时，将正常进给控制模式切换到交替进给控制模式，在这种情况下，以织造物以一定量进给的方式产生由密集布置的之字形针迹组成的选定图案每当产生一个替代的之字形针迹时，选择的值加倍。在替代进给控制模式中，要施加到图案的第一针迹的织物进给量为零，或者是根据图案的形状和第一针的针位置确定的选择量的两倍的模式。

摘要： A sewing machine having a threading device is disclosed. The sewing machine comprises a needle bar having a needle attached to a lower end thereof. The needle has a needle eye and a threading shaft has a threading member mounted to the lower end thereof. The threading member has a threading hook, a drive motor for vertically moving the threading shaft along the needle bar, guide means for guiding and rotating the threading shaft at a threading position as the threading shaft is vertically moved, and a regulating member for deciding the threading position of the threading shaft. The threading shaft is moved down and stopped at the threading position and is axially rotated to pass the threading hook through the needle eye. The threading shaft is maintained in this state until a return signal is given such that the drive motor is driven again to pull the threading hook out of the needle eye and move up the threading shaft.

摘要： Disclosed is an electronic zigzag sewing machine adapted to produce one or more of buttonhole stitch patterns, including several parts to be sequentially stitched, in response to stitch control data stored in a memory unit. The sewing machine includes a vertically extending presser bar, to the lower end of which there is detachably mounted a presser foot for exerting a downwardly directing pressure onto a workpiece. The presser foot is provided with a photo-sensor capable of detecting a longitudinal end of a buttonhole during stitching operation of the buttonhole stitch pattern; a step-up timing, at which one part of the buttonhole stitch pattern proceeds to the next part, can be automatically detected so that the buttonhole stitch pattern can be produced step by step without necessity of manual operation. With another presser foot provided with no photo-sensor means, the operator manipulates a key button when visually determining the step-up timing, in response to which the one part of the buttonhole is likewise renewed to the next part.
