Abstract: The invention which is the subject of this application relates to apparatus for use in forming a malleable material such as, but not exclusively, modelling clay into a desired shape. The apparatus is provided for the reception of mold pieces therein which determine the shape of the malleable material and said mold pieces are arranged to be brought together to press the malleable material placed between the same into the required shape. The apparatus further includes a member which serves to locate and support the malleable material in the form of the shaped article in a fixed position at least at the instant when the mold pieces are moved apart thereby ensuring that the malleable material is not damaged by the removal of the mold pieces and is not required to be handled or held while the mold pieces are moved apart. This therefore minimizes the damage to the article formed.

Abstract: In the production of various kinds of pastry it is actual to effect a folding-over of wing portions of flat dough members, such that these portions are folded down over some stuffing deposited e.g. on a middle area of the dough member. While this is easily done manually, it has been very difficult to automatize the operation, but according to the invention this is achieved in a very simple and efficient manner. A rubber resilient shaping plate (8) is used, which, through foldable areas (12), is connected with projecting wing portions (10) each associated with a depending rubber rod (16). At their lower ends these rods are rigidly attached to an actuator plate (18), which, in being raised relative to the shaping plate (8), urges the rubber rods upwardly for folding the wing portions (19) up- and inwardly.

Abstract: Apparatus for folding a dough leaf 30 about a filling 32 comprises a series of folding pans 26.1 to 26.6. Each folding pan is foldable with respect to the next pan in the series about a folding axis 28.1 to 28.5, and is provided with a weighted plunger 34 which is connected to the folding pan by a lost motion connection. The weighted plunger serves to hold the dough leaf down while the pan is displaced from the folded position back towards the unfolded position, to prevent the dough from sticking to the pan.

Abstract: An apparatus for opening and closing a mold is described herein, wherein a movable mold is revolved and pivotally moved in association with a mold opening and closing operation. When opened, the mold is maintained in a sideways position such that the mold surface faces outwardly. In this manner, the molded article recovery operation is simplified, and monitoring of the mold surface by an industrial television set (ITV) is facilitated. In the mold opening operation, the movable mold begins at a position opposed to a fixed mold. As the mold is opened, a pinion is rotatively driven by a rack which is moved downward in association with the mold opening operation. In this manner, a rotatable block is revolved and pivotally moved along with the movable mold to a position so that the movable mold and the molded article are pointed outwardly. Ejection pins may then be used to eject the molded article off the mold.

Abstract: For forming a resin-impregnated, fiber reinforced composite material sheet having laminated meshes of fibers into a U-shaped cross section, the sheet is placed onto a stationary forming die and an auxiliary forming die with the fibers of the sheet forming angles of approximately 45.degree. relative to opposite edges of an upper reference forming surface of the stationary die. Then, the sheet is pressed from above by a pneumatically expandable, elastic depressing die, whereby the auxiliary forming die is lowered against a resilient force relative to the stationary forming die. As the sheet is pressed further downwardly by the depressing die, the parts of the sheet which are to form flanges of the product are firmly held between the depressing die and the auxiliary forming die and bent downwards while the parts are subjected to extending forces in directions to prevent creases and lines from being formed by means of auxiliary forming ridges on the auxiliary forming die.

Abstract: In a double-band or similar press the pressure on the mat that is being fed in is increased so rapidly as soon as this mat comes into contact with the heat-transfer surfaces that the outer areas of the mat harden under the great pressure, whereas the heat has still not penetrated into the interior of the mat. This results in an enhancement of the surface quality of the panel. As an example, to this end, a roller gap can be provided before the feed gap.

Abstract: An oval dish forming machine has two revolvable wheels each of which is supported on a structure permitting the wheel to move in an eccentric pattern so that discs of clay on carriers on the wheels may be formed in desirable oval shapes. One of the wheels comprises a first or spreading station where the disc of clay is subjected to a rolling extruding action of a cone-shaped roller which squeezes the clay against the carrier to form a desirable oval shape. The carrier and the initially shaped clay is then manually moved to a second or finishing station where a dumbbell shaped roller engages the clay shape on the carrier and rolls the excess clay from the shape to the desired configuration of the oval dish. The dumbbell shaped roller is stopped in the last revolution of the wheel so as to smooth the clay by a sliding action. Motion of the two shaping and finishing rollers is controlled to properly process and shape the clay so as to insure the removal of air and excess moisture therefrom.
