  • Patent number: 5014453
    Abstract: An improved head and buck for a fabric pressing machine, each comprising a hollow casting. The head has an upper steam chamber and a lower spray chamber. A cowling surrounds the head steam chamber, having air intake holes at one end and an air valve near its other end directly connecting the cowling to the spray chamber. The head has a resilient peripheral sealing element engaging a peripheral rim on the buck when the head is closed thereagainst. The buck has a vacuum valve connecting the buck to a source of vacuum. With the head sealed about the buck, air in heat exchange with the head steam chamber within the cowling can be drawn through the workpiece during the drying step of the pressing cycle by opening the buck vacuum valve. The buck is provided with a grid plate, pad and cover assembly which is divided longitudinally into front and rear halves.

  • Patent number: 4763600
    Abstract: An apparatus for permanently setting pre-formed creases of a pair of pants comprises a stanchion member and a pair of spaced-apart substantially parallel support members extending substantially horizontally from the stanchion member. A substantially horizontal upper crease blade is fixed to each support member and has a lower crease blade pivoted thereto. The free ends of the crease blades extend away from the stanchion member and include applicator nozzles that are directed upward for the upper crease blades and downward for the lower crease blades. When a pair of pre-creased pants are slipped over the crease blades and the lower crease blades are pivoted downward, the pants are pulled taut at the hems between the pre-formed creases. As the pants are pulled off of the crease blades a pumping mechanism supplies a flowable, curable setting material such as silicone rubber to the applicator nozzles, which apply a coating of setting material to the inside surfaces of the pant legs along the creases.

  • Patent number: 4599814
    Abstract: In the case of common trough mangles (1) used for the smoothing and drying of wet laundry pieces (11) wherein the hollow rollers (2) provided with roller wrappings (3) are only partially surrounded by heated pressing troughs (4, 5), a considerable amount of energy is wasted due to the absorption of cooler room air. In order to eliminate the cause of this deficiency, the invention proposes to cover the free area of the hollow roller (2) with a hood (6), whose rims (9) are sealed against the roller wrapping (3). The exhaust (8) of the steam is removed directly from the hood (6). This way, inside the hood (6) clean saturated steam is obtained and superheated, when the absorption from the hood (6) takes place in counterflow with regard to the travel of the laundry pieces (11). This superheated saturated steam is especially suitable as operating means for washing machines or the like.

  • Patent number: 4498254
    Abstract: An apparatus for decreasing the friction of pieces of wet or damp laundry pressing surfaces of one or more steam trough mangles applies a liquid lubricating agent such as silicone oil or silicone oil emulsions. The lubricating agent is applied in atomized, pressurized form uniformly over the entire width of the pressing surface of one or more steam trough mangles with the droplets of the atomized, pressurized lubricating agent being applied at the same time to the entire width of the pressing surface. The lubricating agent which has been atomized in at least one atomizer by a gaseous medium under pressure is transportable by such a gaseous medium through at least one conduit and is delivered to the pressing surface of the steam trough mangle through a pipe which extends substantially horizontally over the entire width of the pressing surface and which has openings extending over substantially the entire length of the pipe.

  • Patent number: 4236330
    Abstract: An ironing installation possessing an ironing machine having two hollow rolls and four heating elements which can be heated by water vapor. During operation water vapor and hot air are sucked into the rolls through holes at the roll shells or jackets. This water vapor-air mixture is expelled to the surroundings through a heat exchanger. Ambient air is sucked into an air infeed line or conduit and infed through the heat exchanger into the internal compartment of a casing which at least partially encloses the rolls and heating elements. Between the aforementioned heat exchanger and an outlet opening or mouth of the air infeed line there is arranged a passage of a second heat exchanger in the air infeed line. A further passage of this second heat exchanger is connected with outlets of the four heating elements.
