The machine comprises a frame (1) containing at least one tray (2, 3) of granules which fall freeely into a tube (4) from which they are pushed by an Archimedean screw (6) into a preheating chamber (7) which turns them into a pasty material. Said material then passes into a heating element (11) for heating up to a suitable temperature for extrusion by means of an spreading slot (14) between two slightly projecting rods (15) on which the edges of the skis rest. This machine for repairing plastic glide surfaces of skis works, for example but not exclusively, by extruding plastic in the form of polyethylene granules.
