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.

摘要翻译： 当下线通过面线张紧时，下线张力装置以一定的工作距离被致动，具有非常小的阻力，使得下线被拉出，好像没有阻力。 如果在所述距离之外的所述张力下进行底线，则不会以较大的阻力拉出。 致动装置从相位传感器连续接收关于每个针迹中消耗的线的信息和关于缝纫机的旋转相位的信息。 在强阻力的距离内，禁止下线拉拔，螺纹在该距离内拧紧。

摘要： A sewing machine includes an automatic thread tension adjusting device comprising an upper thread tension member arranged in an a thread running path between an upper thread source and a main thread take-up lever. An auxiliary thread take-up lever is arranged in the upper thread running path between the main thread take-up lever and a needle holding the upper thread. A thread engaging part guides the upper thread. A thread presser is arranged laterally of the upper thread running path between the main and auxiliary thread take-up levers and normally clamps the upper thread. A detector detects a predetermined rotation phase of a drive shaft of the machine and thread elongation, respectively, and generates respective electric signals. A control circuit causes the thread presser to release the upper thread in response to the electric signals generated by the detector.

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.
