A portion of the inner die is arranged to be disposed between the end flanges of the outer die and spaced apart therefrom to define a cavity corresponding to the desired cross-section of the C-section component to be formed. The radiused convex and concave portions have a radius of curvature that varies about the circumference of the respective inner and outer dies. The inner and outer dies are rotatable such that the radius of curvature of the radiused convex and concave portions where the inner and outer dies are adjacent to one another varies as the inner and outer dies are rotated.

    Abstract: A reflector molding apparatus includes two pressure rollers with pressure surfaces of the rollers comprising convex teeth and concave teeth in mesh. The reflection film is put on the aluminum sheet as the unmolded material. The unmolded material goes to the pressure surfaces in mesh and is molded to be a reflector. The surface of the resulting reflector is corrugated shaped because of the pressure of the rollers. The shape of the reflector changes with the pressure surface of the rollers.

Interdigitation of the two profiles is achieved by cold forming the profiles while interlocked. 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: 4694741
    Abstract: In an apparatus for making a rolled wafer cone from a baked flat wafer blank made from a sugar-containing wafer dough, the baked wafer blank is rolled to form a wafer cone in a winding mold while the wafer blank is still in a soft, deformable state after the baking operation. Thereafter the rolled wafer cone is permitted to harden. In order to ensure the production of wafer cones having consistently exactly the same shape, it is proposed that the wafer cone which is unrestrained at least in part is shortened in the winding mold to a predetermined length while the wafer cone is adapted to be plastically deformed. For this purpose the rolled wafer cone disposed in the winding mold is subjected to a plastic deformation only at one end or only at both ends.

  • Patent number: 4110482
    Abstract: A method for forming rolled sheet articles, such as cookies, which are rolled after heating, by advancing, preferably on a conveyor, the sheet tangentially into association with a roll-up roller. The roll-up roller is rotated at a slower speed than the movement advance of the surface and it engages the sheet article or cookie and causes the bending thereof around its surface. A roller board is arranged adjacent the roll-up roller and it includes a stopper which prevents complete rolling of the article around the roll-up roller and instead deflects it forwardly in the feed advance direction of the conveyor. A friction surface is arranged above the conveyor and it is either stationary so that it provides a drag on the periphery of the partially rolled up article so as to complete its rolling during the advancing movement of the conveyor or it is moved in a direction and in an amount to cause a frictional drag on the periphery of the cookie and to continue its rolling and winding movement.
