  • Patent number: 8740606
    Abstract: A press device for the energy-efficient curing of a sandwich component for an aircraft, includes an open and mechanically adequately loadable core structure with cover layers applied to one side or to both sides. The sandwich component is restrained between a pressure piston, an abutment and sidewalls of the press device, thus forming an essentially closed interior space. At least one of at least one cover layer and the core structure includes a curable duroplastic plastic material. A conveying device feeds heated air through the core structure of the sandwich component in a closed heated-air circuit or preferably in an open heated-air circuit in order to ensure energy-efficient curing of the sandwich component from the inside out. The heated air is temperature-controlled by a heater. In the case of an open heated-air circuit, heat recovery by a heat exchanger is provided.

The shape of the cold form is a stepped deflection of both profiles so that their shapes are generally congruent. The stepped deflections provide a change in the occlusion and peel force of the interlocking closure device thereby resulting in an audible clicking or popping sound as the closure device is opened and closed and a tactile effect that is perceptible to the touch as the closure device is closed.

  • Patent number: 6371750
    Abstract: A device for smoothing and cooling of a material sheet (8) of thermoplastic, especially a film or sheet which are processed into plates which have been extruded by an extruder via a sheet die. Two pairs of units (2, 3; 4, 5) are provided which oppose each other and act on the surfaces (9, 10) of the material sheet (8). The units each have an active area (11) to contact the material sheet (8) forming part of the metal belt (12). The lower surface of the metal belt (12) is coolable in areas below the active area (11). The metal belt (12) is guided over a driving roll (20), which is drivable. The units provide a universal temperature profile, which is achieved over the thickness of a material sheet (8) while cooling and smoothing the sheet. Accordingly, stress differences are prevented.

  • Patent number: 6276919
    Abstract: An automated pretzel forming machine that produces fresh unbaked pretzels with hand formed characteristics by extruding premixed dough onto a folding table. This table is moved by a bi-directional positioning stage, forming the unfolded and untwisted pretzel shape. The folding table twists the ends of the extruded dough rope then folds the twisted portion on top of the main body of extruded dough resulting in the classic hand twisted pretzel shape. The twisted and folded pretzel is transferred from the folding table through the use of a lift and rotate unit and is subjected to a patterned soda spray and salted before being unloaded from the lift and rotate unit to an existing conveyor oven.
