Abstract
1. Method for cleaning pallets for the moulding of plates of hardenable plastic material, for instance of concrete roofing tiles, in an extrusion process in which, on the pallets which are brought to a coating installation on a carrying device with adjacent abutting edges, a continuous coat of the plastic material is applied and, afterwards, compressed by means of a moulding cylinder and of a smoothing tool and, if necessary, profiled ; the compressed coat is further cut in a cutting station at the abutting edges of the pallets into plate shapes which will be later hardened, if necessary, under high temperature, and then separated from the pallets and afterwards taken away while the pallets are carried back to the coating installation, characterized in that pallets are swivelled about an axis in the conveying direction at least once before the renewed coating with the plastic material and, afterwards, swivelled back again into their conveying position, while the pallets placed before and behind a swivelled pallet and adjacent to it are respectively maintained in their conveying position, so that the hardened material sticking on its abutting edges is herewith sheared off.
