摘要： The invention relates to a production method comprising the following steps: the material to be moulded is introduced into a mould (14); the mould is arranged in an envelope (12) comprising a vacuum connection (15); a depression is formed in the envelope by the formation of a gaseous flow through the vacuum connection; the mould is deshaped; the gaseous flow is stopped; and pressure is applied to at least part of the mould, possibly via the envelope, at least once the gaseous flow has been stopped. The invention also relates to a device for moulding parts.

摘要： A demolding apparatus (10) for removing molded building products (30) from a mold (12) has a conveyor assembly (50) to advance the mold in a machine direction. A removal mechanism contacts a dislodged portion of the molded building product and applies a dislodging force to the dislodged portion of the molded building product.

摘要： Eine Vorrichtung (1) dient zum Festlegen von Platten (2). Die Vorrichtung (1) weist eine wasserundurchlässige Hülle (3) auf, die mit mindestens einem hydraulischen Stoff (4) gebildet ist. Dies gewährleistet eine leichte und damit kostengünstige Verlegung der Platten (2), wobei diese trotzdem fest verlegt sind. (Figur 1)

摘要： The invention concerns a mould comprising at least two inflatable structures (2, 3) linked to each other by means maintaining in position and shape their moulding surfaces (21, 13, T) so as to define between them an inflated volume wherein the moulding material can be introduced, the demoulding being carried out, after the material has set, by deflating the structure. The invention is applicable in the building industry and public works.

摘要： A system for the automatic release of cast concrete products from flexible and deformable moulds is described. The system has an apparatus configured to supply the moulds and carry out the pre-mould-release of the products contained within such moulds. The apparatus has a first conveyor belt associated with a first pre-mould-release group and a second conveyor belt associated with a second pre-mould-release group. The second conveyor belt is placed downstream of the first conveyor belt and both pre-mould-release groups are configured to facilitate the subsequent mould-release of the products. The system further has a mould-release machine arranged downstream with respect to the first and second conveyor belts. The mould-release machine has a mould-release group, configured to carry out the extraction of the products from the respective moulds, and a plurality of conveyor belts, configured to move the moulds and the products inside the mould-release machine.

摘要： Stapelträgersystem für die Herstellung von Betonprodukten,
umfassend eine Gießharzform (1), einen Stützrahmen (3) und mindestens eine Bodenplatte (5),
wobei der Stützrahmen (3) und die Bodenplatte (5) formschlüssig miteinander verbunden sind und die Gießharzform (1) seitlich und von unten formschlüssig umfassen,
wobei der Stützrahmen (3) und die Bodenplatte (5) bei 25°C eine größere Härte als die Gießharzform (1) aufweisen,
wobei die Gießharzform (1) mindestens eine Vertiefung (7) für Betonprodukte umfasst,
wobei der Stützrahmen (3) aus Holz, einem Kunststoffmaterial und/oder einem metallischen Material gefertigt ist, wobei die Bodenplatte (5) aus Holz, einem Kunststoffmaterial und/oder einem metallischen Material gefertigt ist und
wobei der Stützrahmen (3) höher ist als die Gießharzform (1).摘要翻译： 该系统具有支撑框架（3）和底板，其形状配合方式彼此连接并且在25摄氏度下包括比铸造树脂模具（1）更大的硬度。 浇铸树脂模具具有用于混凝土产品的凹部（7），支撑框架和基板由木材，塑料材料和/或金属材料制成。 支撑架高于铸造树脂模具。 凹部通过杆（9）彼此分离，并且模具由聚氨酯制成。 框架由电解镀锌板形成。 还包括用于生产混凝土产品的方法的独立权利要求。

摘要： The method includes providing a rigid mould (8, 150) with at a re-entrant cavity (96, 196). Mouldable material is provided on the rigid mould and the re-entrant cavity is filled to form a hook-like protuberance (36) on a surface of the moulded building product to facilitate, in use, the attachment of the building product to the structure of a building. The mouldable material sets to form a building product. The building product is removed from the mould. The re-entrant cavity has a resilient portion to facilitate the removal of the building product without detrimental affect to the hook-like protuberance. The so-formed building products have a greater resistance to inclement weather conditions. The building product may be a concrete roof tile formed by a roller and slipper extrusion method, a clay tile made by pressing in a clay tile press, or a cast concrete roof tile.

摘要： The shuttering has side walls (5) which can be pivoted away and a rib on each side wall (5) facing inwards and forming a groove for a sealing frame in the tubbing produced therein. Said rib has a rib bearer (13) which is distant from the side wall (5) and forms recesses (14) therewith. Into each recess is inserted a shaping rib (15) which completes the rib bearer (13) to form a rib. The shaping ribs are elastically deformable. Thus when the side walls (5) and hence the ribs are pivoted away, not only is damage to the tubbing groove just produced prevented but also noses (17) forming recesses in the groove can be provided which are inconceivable in non-deformable ribs owing to the impossibility of moving them out of the recesses.

摘要： For use in manufacturing concrete building products in polyurethane moulds, a demoulding apparatus provides a clamping bar which clamps on to a lip of a mould (22) and is then moved with pivotal arms (32, 34) forward and upwardly to effectively strip the edge of the mould (22) from the front end of the respective product (24). The reciprocating mould (22) passes below a roller (66) which moves into engagement with the upper surface of the mould (22) to apply a downwardly directed pressure onto the mould and product, thereby to retain the product (24) on a conveyor (12) and rollers (68), and facilitate stripping of the mould (22) from the product (24). The stripped product (24) moves onto an offtake conveyor (70) and, in the uppermost position of the arm (32, 34), the clamping jaws are released to allow the stripped mould (22) to thereafter fall onto the conveyor (70).
