The installation comprises an infeed conveyor (7) and an outfeed conveyor (8) with, between the two, a module (5) for forming a wrapping of the tray or wrap-around type, the cleated belt conveyor (11) of which is constituted by two continuous belts (11a, 11b) which are retractable so as to allow the installation of a substitute conveying system (13) which is capable of forming a continuous slider bed between said infeed conveyor (7) and said outfeed conveyor (8). This arrangement makes it possible to provide a versatile installation which is capable of carrying out on the one hand, wrapping operations with blanks of the tray or wrap-around type and on the other hand, simply transporting batches of products, said products being, for example, placed on supporting cardboard sheets so as to convey them to the packing machine to receive a plastic film and then into the heat-shrink tunnel to complete the wrapping. |
