Abstract: The invention relates to an apparatus for moulding plastic products (31'-36'), said apparatus comprising at least two plastic moulding machines (1', 2') each of which comprises a robot (7'-8') for transferring a moulded product (31', 32') from the moulding machine onto a conveyor belt (30'). In order to significantly facilitate and expedite quality inspection and thus also to allow any quality defects to be rapidly corrected, and in order to considerably simplify the transport of the products and the structure of the apparatus, said at least two moulding machines (1', 2') are mounted along a common conveyor belt (30') substantially successively on the same side of the belt, whereby their robots (7', 8') are arranged to place the moulded products (31', 32') at different points over the width of the belt.
