Abstract: A punching device including a punching die (5a) that can be connected to the needle bar and a punching matrix (5b) that can be fastened to a needle plate (7) of a sewing machine. The punching matrix (5b) is embodied as a lid of a clippings container (9). The planar object (23) to be processed is displaced via the tambour frame in a punching plane L2, with this punching plane L2 being arranged parallel above the sewing plane L1.

Abstract: The activation for a path and time related motion of a thread cutting and lead-in stitching unit (7) and the thread brake (25) occurs by a cam drive driven by the primary shaft (9) and a cam drum (75) arranged on the upper shaft (17). This way, an absolute synchronization of the elements of the thread cutting and lead-in stitching unit (7), the thread brake (25), and the hook as well as the needle is ensured.

Abstract: A punching device (1) is fastened at the pressure shaft of a sewing machine, vertically displaceable via a carrier (3). The vertical position of the press pad (35) at the body (33) can be adjusted by an adjustment screw (16) to the thickness of the textiles/work pieces to be processed.

Abstract: A placement device (3) for placing decorative elements (5) on a textile or non-textile sheet material is connected to a sewing machine. The decorative elements (5) are stored in an ordered way in magazines (7) and are fed in a controlled way by the control of the sewing machine to the appropriate set positions on the sheet material (39) and are connected to this material.

Abstract: A method for cutting the lower and at least one upper thread for lead-in embroidering or lead-in sewing is performed with a device including thread catchers (19a-19c) connected with each other in a fixed manner and layered over top of each other, formed of sheet metal, as well as spring and thread tightening plates (31 and 41) arranged above and below the thread catchers, which move back and forth against a blade (29), and a thread wiper unit. The device is exclusively operated by a drive moving back and forth and driving the thread cutting and lead-in stitching unit (5).

Abstract: A locking mechanism for a bobbin case (5) is provided with a locking lever (35) supported pivotally in the bobbin cover (27). The locking lever is pivotal on a shaft (33). A hook-shaped end (51) is formed at the locking lever (35), which latches in the sleeve (9) in the hook and can hold the bobbin case (3) in the hook (1).

Abstract: For the continuous drive of a hook of a sewing machine, two drive cams (17) alternately engage in the back of the hook. During the passing of the upper thread loop, the respective drive cam (17) on which the thread would get hung up is out of engagement. The hook is situated in a conical hook race guide and is held therein by magnets.

Abstract: A holding device (3) for a tool, e.g., a textile marker (5), for the processing of a textile or non-textile sheet material (44) is attached to the presser foot bar (23) of a sewing machine (1). The tool is supported by a tool holder (15) so that it can move on a base part (19) of the holding device (3) and can be changed in its position or activation through movements of the needle bar (9) of the sewing machine (1).

Abstract: A device for cutting textile and non-textile sheet materials with a sewing machine having a turning device (9) that can be mounted on the lower end of the needle bar (5). A cutting needle (23) is inserted from below into the turning device (9) instead of a sewing needle and can be brought into the desired cutting position, for example, by a fin (17) that projects from the turning device (9).

Abstract: The activation for a path and time related motion of a thread cutting and lead-in stitching unit (7) and the thread brake (25) occurs by a cam drive driven by the primary shaft (9) and a cam drum (75) arranged on the upper shaft (17). This way, an absolute synchronization of the elements of the thread cutting and lead-in stitching unit (7), the thread brake (25), and the hook as well as the needle is ensured.

Abstract: An embroidery hoop (1) for a sewing machine or embroidery machine having two hoop parts, namely the lower hoop part (3) and the upper hoop part (5). The two hoop parts (3, 5) are connected to each other by a hinge that can be released without the use of tools. The embroidery material is clamped between the inner hinge element (9) on the lower hoop part (3) and the outer hinge element (15) on the upper hoop part (5). Through this measure, an embroidery material can be embroidered at any position.

Abstract: A method and the device for displaying sewing processes to allow simulation of the formation of stitch patterns and embroidery patterns in sewing machines (1) and embroidery machines or in sewing simulators close to reality is provided. In the representation on the monitor (3) features, such as colors and the structure of the sewing material (2), are considered. By activating a simulation mode, the drive for the stitch formation unit can be disabled.

Abstract: A method and a sewing machine are provided to form sewing patterns allowing the stitching width to be changed during sewing for a flexible adjustment of parameters of the sewing pattern. In particular the stitch length a can be changed without changing the exterior design of the sewing pattern.

Abstract: A locking mechanism for a bobbin case (5) is provided with a locking lever (35) supported pivotally in the bobbin cover (27). The locking lever is pivotal on a shaft (33). A hook-shaped end (51) is formed at the locking lever (35), which latches in the sleeve (9) in the hook and can hold the bobbin case (3) in the hook (1).

Abstract: A sewing machine (1) having selection device for selecting one or more adjustable parameters to be respectively selected and a common adjustment device for adjusting the values of each of these parameters. The adjustable parameter values are displayed by a display, with the display being arranged behind an opaque cover and being invisible in the switched-off state.

Abstract: A punching device (1) is fastened at the pressure shaft of a sewing machine, vertically displaceable via a carrier (3). The vertical position of the press pad (35) at the body (33) can be adjusted by an adjustment screw (16) to the thickness of the textiles/work pieces to be processed.
