    摘要: The invention relates to a stitch-forming machine, notably an embroidery machine, sewing machine or sewing system, comprising at least one thread for embroidering or sewing, namely at least one upper thread (4) and at least one lower thread, as well as a device for recognizing malfunctions in the area of the thread. The invention also relates to a corresponding method. The device comprises at least one thread bar (5) by means of which the upper thread (4) is deflected. The thread bar (5) can be deflected from an unsolicited initial position against a restoring force in the direction of a force which results from the tension of the upper thread (4) and is applied in the plane defined by the deflected upper thread (4). At least one detection device for detecting the thread bar deflection caused by the thread tension force is assigned to the thread bar. The device further has evaluation means which present at least one averaging element and at least one comparator.

    摘要: The control circuit (15) of a catch thread device has a counter (22) for the main shaft of the sewing machine. The counter (22) counts the number of revolutions of the main shaft (26) during the reception of one of at least two signal intensities and is reset to its initial value when this signal intensity changes to the other signal intensity. When a predetermined maximum number of revolutions is reached, the counter (22) emits a signal indicating a thread fault.

    摘要: A slit (7) is formed which lies in a vertical plane and extends from an upper surface of a sewing machine frame (1) to a front surface. A tension device (5), a thread take-up spring (30), and upper and lowerthread guides (23, 24) are disposed along the direction in which the slit (7) extends. A thread take-up lever (12) is installed so that it is reciprocated horizontally across the space between the pair of thread guides (23, 25). The placement of the thread in the tension device (5), thread take-up spring (30), and two thread guides (23, 24) can be attained by simply pulling the upper thread vertically downward through the slit (7). When the thread take-up lever is reciprocated, during its forward stroke it arrests the portion of the thread positioned between the two thread guides (23, 24) and draws it in V form. During its return stroke, the thread take-up lever (12) releases the thread to allow the latter to loosen in loop form.

    摘要: A drive control mechanism and a safety device in a sewing machine in which thread in a predetermined amount necessary for the formation of one seam each time a seam is to be formed. The drive control mechanism comprises a control circuit for allowing current to flow to a machine motor when no thread amount signal is produced though a position signal is produced at the start of the machine. The safety device comprises a thread paying-out detection circuit operable when a position signal is produced. but no thread amount signal is produced, an alarm for producing a sound or light warning in response to the operation of the thread paying-out detection circuit and a motor stop circuit for inturrupting flow of current to a machine motor.

    摘要: A sewing machine having a reciprocatory needle (9) and a reciprocatory thread-take-up device (17) to deliver thread (11) to the needle (9) employs a thread control device (16) located between the thread take-up device (17) and the needle (9) to engage and apply light tension to the thread (11). The thread control device (16) can have an opposed plate (25) and spring wire (24) between which the thread runs and which cooperate to apply spring pressure to the thread. Downstream thereof a thread brush (27) can be employed through which the thread runs. The thread (11) can be further lightly tensioned and laterally positioned by the thread brush (27). The guide plate or other device can include catcher structure to catch thread escaping the take-up device. The thread control device can help control premature descent of the thread and improperly tensioned stitches.
