A kit for adding or replacing an automated upper walking foot stepping height adjustment to a sewing machine, the kit includes a mounting assembly including an actuator bracket, an actuator coupled to the actuator bracket, a drive assembly, and a needle drive assembly. The actuator includes an actuator shaft that extends and retracts. The drive assembly includes a drive shaft, a drive arm coupled to the drive shaft and the actuator shaft, and a guide coupled to the drive shaft. The needle drive assembly includes a variable drive crank coupled to the guide and configured to couple to a needle drive shaft of a sewing machine. Selectively extending and retracting the actuator shaft selectively adjusts a stepping height of an upper walking foot.

A presser foot tube maker apparatus includes a hollow form with a first end and a second end and an inside and an outside and a presser foot configured for attachment to a sewing machine. And an adjustment base is provided where the hollow form is connected with the adjustment base and where the presser foot is connected with the adjustment base such that location of the hollow form and the presser foot relative to the adjustment base is adjustable.

A presser foot position retainer includes a presser foot and a restricting member. The presser foot is swingably attachable to a presser holder of a sewing machine. The presser foot includes a shaft extending in an axial direction, a restricted portion, and a pressing surface configured to press a workpiece. The restricting member includes a restricting portion capable of contacting the restricted portion. The restricting member is attachable to the presser holder. The restricting member is configured to move between a first position and a second position by a user operation. When the restricting member is located at the second position, the restricting portion is in contact with the restricted portion to limit a swingable range within which the presser foot attached to the presser holder is swingable about the shaft to less than that when the restricting member is located at the first position.

A hopping foot assembly for a sewing machine having a needle comprises a hopping foot base and a hopping foot arm extends axially from the hopping foot base relative to an axis. The hopping foot base is shaped to include an opening that extends axially through the hopping foot base relative to the axis. The hopping foot arm is configured to be coupled to the sewing machine to fix the hopping foot base relative to the sewing machine.

A presser foot (1) for a sewing machine, having a shank (4) for fastening the presser foot (1) to a sewing machine, a needle opening (5) through which the sewing machine needle is able to be guided during sewing, and a presser foot sole (6) having an elongate depression (7) in the presser foot sole (6). The elongate depression (7) forms a guide wall which during sewing is configured to guide a filler material (8) to be sewn into the fabric (2) in the transport direction laterally beside the needle opening (5) and past the needle opening (5), and press said filler material against the fabric to be sewn, wherein the spatial extent of the elongate depression (7) is variably adjustable.
