The invention concerns a blind stitch sewing machine with an oscillating fabric deflector to make the sewing material bulge into the arcuate path of the arc needle. The minimum spacing of the deflector relative to the arc needle can be adjusted in relation to the thickness of the sewing material detected by a sewing material sensor. A stepping motor is provided to adjust this minimum spacing. A stepping motor control circuit is connected to the sewing material sensor, and to a contact pickup for the arc needle and fabric deflector, the stepping motor being controlled in such a manner that, upon a control circuit start signal, it moves into a particular start position and proceeds during the ensuing sewing by one step per stitch reducing the minimum spacing of the fabric deflector until the contact pickup emits a contact signal relative to the arc needle and the fabric deflector during a measurement window signal. At the end of this signal, the stepping motor moves in the opposite direction by a number of steps dependent on the output signal of the sewing material sensor, to increase the minimum spacing of the fabric deflector.

Blind stitch sewing machine

A fur sewing machine having a blower device connected with a source of compressed air which deflects the fur hairs of the material to be sewn during sewing. The connecting line between the source of the compressed air and the blower contains a heating device which heats the compressed air. A mechanism for controlling the air flow and the heater is also provided.

An ironing table has a hollow table top (1) and a blower (11) arranged thereunder. The blower is connected to the table by a pivotable buffle (25), a helical housing (14), and a fixed orifice (12) located in a bottom section of said table. The top of the housing includes a suction orifice (12) and a pressure orifice (13). The blower and its housing are supported on rails (20) and may be displaced between two positions where the blower either applies a pressure or suction force to the surface of the table.

An apparatus for pressing cloth with a heated iron has a surface for supporting a cloth or other material to be pressed, one or more fans for moving air over the ironing surface by suction or by blowing and a switch for controlling electricity that drives the fan. The switch has a first capacitor which is disposed below and in front of the ironing surface. The switch is shaped to the outline of the ironing surface. A second capacitor having a semi-cylindrical cross-section is disposed between the first capacitor and the ironing surface.
