PURPOSE:To keep constant the shape of a foamed sheet material at the time of processing and to simplify a working process in the feed of the foamed sheet material under cooling. CONSTITUTION:The foamed sheet material 6 pushed out of a foaming oven 1 is transferred to a perforated feed belt 3 through expander rolls 2a, 2b and cold air is blown against both upper and rear surfaces of the foamed sheet material 6 on the feed belt from cold air supply nozzles 11a-11c, 12a-12b. Since the cold air blown against the foamed sheet material 6 is discharged toward the rear surface of the feed belt 6 so as to press the foamed sheet material to the feed belt 6, the foamed sheet material 6 integrally runs along with the feed belt 6 in an almost close contact state. |
