摘要： A sewing machine comprises a thread deflecting device arranged between a thread take-up lever and a needle and which in response to a swinging movement of a needle bar effected in response to selection of a zigzag stitch, deflects the upper thread laterally of a fabric feeding direction. A thread blocking device is provided on one side of the thread deflecting device. The sewing machine further comprises an actuator operated in response to actuation of a zigzag stitch pattern selecting key to move the thread blocking device to an operative position thereof. The thread blocking device in the operative position blocks the upper thread as it is deflected in one direction by the thread deflecting device to give a predetermined degree of tension to the upper thread, so that the stitch is tightened on one side of the zigzag stitch in addition to the tightening of the stitch by a thread take-up lever.

摘要： An automatic thread tensioning device for positioning the crossing points of upper and lower threads in the center of thickness of a fabric undergoing stitching. The positioning is effected by making calculations based on measured results of thread tension, without needing to detect the various kinds of characteristics of fabrics, threads, or lower thread tension responding to an existing type of stitching condition. The proper upper thread tension may be determined for the stitching conditions of fabrics which have different characteristics and for stitching conditions of fabrics which have conventionally been difficult to deal with, simply by pressing buttons and making test stitchings. If an upper thread tensioning device has a motor, a stitching operation may be made more easily.
摘要翻译：一种自动线张紧装置，用于将上，下螺纹的交叉点定位在经历缝合的织物的厚度的中心。通过基于线张力的测量结果进行计算来实现定位，而不需要检测针对现有类型的缝合条件的织物，螺纹或底线张力的各种特性。可以根据传统上难以处理的织物的不同特性和缝合条件的织物的缝合条件，仅通过按压按钮和进行试验缝来确定适当的面线张力。如果面线张紧装置具有电动机，则可以更容易地进行缝合操作。

摘要： When a lower thread is effected with tension by an upper thread, a lower thread tension device is actuated in a certain working distance with very small resistance to an extent that a lower thread is drawn as if without resistance. If the lower thread is effected with said tension outside of said distance, it is not drawn out with large resistance. An actuation means successively receives information about thread consumed in each of the stitches and information about rotation phase of the sewing machine from a phase sensor. In the distance of a strong resistance, the lower thread is prohibited from drawing, and the thread is tightened in this distance.

摘要： A lower thread drawing-out device for a computerized sewing machine, the device having a cup-shaped loop taker with a surrounding wall. The loop taker is rotatable in a timed relation with a vertical reciprocation of the needle to catch the upper thread to concatenate with the lower thread and thereby form lock stitches. A bobbin is arranged in the loop taker so as to form a space between the bobbin and the loop taker surrounding wall. A lower thread drawing out element having a free end in the space is arranged so that when a lower thread is wrapped around the bobbin and extends to a needle, the free end contacts the lower thread at a location. The lower thread drawing out element is rotatable relative to the loop taker. The lower thread is movable transversely at the contact location relative to the lower thread when extended and in response to a rotation of the element relative to the loop taker, thereby compensating for biasing of the lower thread.

摘要： For a hem stitching operation with a sewing machine having a needle vertically reciprocating and also laterally swingable, a hem stitching presser foot is detachably mounted to a lower end of a presser bar of the sewing machine. The presser foot includes a brush like element which confronts a needle dropping hole formed in a sole of the presser foot, a frictional contact between the needle and the brush like element is produced when the needle passes the outside of the fabric edge, without penetrating the fabric, to stitch a portion of hem stitches on the outside of the fabric edge. The brush like element may be secured to the sole of the presser foot, or alternatively to a fabric guide member for engaging and guiding the fabric edge. The brush may be projected in the fabric feeding direction or across the fabric feeding direction. A pin may be located just beneath the brush like element for constant placement thereof.
