Apparatus for cutting to sice roof tiles from an extruded web of concrete mix
Реферат: The invention concerns a device (10) for cutting to size individual shaped parts for roofing tiles from a strip of unset concrete which is continuously fed on a line (16) of contiguous bottom-half moulds (14) of equal length. The device comprises a cutting station (20) with at least one cutting tool on a sliding carriage (22) which can be moved in a reversible manner and is moved at least briefly at the speed of the line (16) parallel to the feed direction (18) thereof. The object of the invention is to provide a device in which more cutting time is available than in known devices, such that deep cuts, for example for verge flashing and gable tiles, can be carried out. To this end, the sliding carriage (22) is driven by a cam mechanism (24) which moves the sliding carriage (22) over a finite path at the speed of the line (16), parallel to the feed direction (18) thereof. The sliding carriage (22) is forcibly guided directly by the cam mechanism (24) which has a substantially heart-shaped cam plate (28) with sections in the shape of an Archimedean screw and comprises guide components (30, 32) abutting the surface of the cam plate (28) and connected to the sliding carriage (22).
