Abstract: 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.

Abstract: The blind-stitch sewing machine includes a fabric bender adjustable between a sewing position wherein the material being sewn will bulge into the arcuate trajectory of the arc needle and a release position allowing the material to be sewn to be inserted and respectively the material having been sewn to be removed, this adjustment being effected through a rocker shaft. This rocker shaft cooperates with a stop defining the sewing position of the fabric bender. The stop is adjustable for setting the stitch-depth of the arc needle into the particular material to be sewn in order to assure a corresponding distance of the fabric bender in the sewing position from the trajectory of the arc needle.

Abstract: 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.
