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).

A holding device (3) for a tool for processing a textile or non-textile sheet material (44) for a sewing machine (1), comprising a presser foot shaft (21) formed on a base part (19) that is adapted to attach the holding device (3) to a presser foot bar (23) of the sewing machine (1), a tool holder (15) that receives the tool is located on the base part (19), and the tool holder (15) comprises a coupling device (39) that is contacted by a transmission element (11) on the needle bar (9) to move the tool to an active position.
A holding device (3) for a tool for processing a textile or non-textile sheet material (44) for a sewing machine (1), comprising a presser foot shaft (21) formed on a base part (19) that is adapted to attach the holding device (3) to a presser foot bar (23) of the sewing machine (1), a tool holder (15) adapted to hold the tool is located on the base part (19), and the tool holder (15) comprises a coupling device (39) adapted for contact with a transmission element (11) on the needle bar (9), wherein the tool holder (15) is movably held on the base part (19), and the coupling device (39) is arranged and oriented on the tool holder (15) such that it can be moved by movement of the needle bar (9) when the holding device (3) is attached to the presser foot bar (23) of the sewing machine (1).
A holding device (3) for a tool for processing a textile or non-textile sheet material (44) for a sewing machine (1), comprising a presser foot shaft (21) formed on a base part (19) that is adapted to attach the holding device (3) to a presser foot bar (23) of the sewing machine (1), a tool holder (15) adapted to hold the tool is located on the base part (19), and the tool holder (15) comprises a coupling device (39) adapted for contact with a transmission element (11) on the needle bar (9), wherein a guide bolt (27, 31) or a different, correspondingly linear guide element is constructed on at least one of the base part (19) or the tool holder (15) such that the tool holder (15) is supported on the base part (19) so that it can be shifted parallel to the presser foot axis (24) when the holding device (3) is attached to the presser foot bar (23) of the sewing machine (1), and the tool holder (15) is held on the base part (19) by a spring force from a spring in a home position or a first work position without action of additional forces.
A method for processing a textile or non-textile sheet material (44) with a tool on a sewing machine, comprising:
- providing a holding device (3) for the tool having a presser foot shaft (21) formed on a base part (19) that is adapted to attach the holding device (3) to a presser foot bar (23) of the sewing machine (1), a tool holder (15) adapted to hold the tool is located on the base part (19), and the tool holder (15) comprises a coupling device (39) adapted for contact with a transmission element (11) on the needle bar (9);
- attaching the tool to the presser foot bar (23) by connecting the holding device (3) to the presser foot bar and connecting the tool to the holding device:
- and
- moving the tool by an effect of the needle bar movement causing the transmission element to contact the coupling device during execution of an up-down movement of the needle bar.
