LAMINATE AND METHOD OF EDGE TREATMENT THEREFOR

摘要

A process for producing laminate (19), comprising the first step of, while supporting, by means of support member (9), laminated material (1) so that peripheral area (1a) thereof is exposed, the laminated material (1) being one of thermoplastic resin composed of a pair of plate members (3,4) piled on each other via longitudinal wall part (2b), blowing hot air onto the peripheral area (1a) to thereby attain heating and softening of the peripheral area (1a); and the second step of pressing the cutting blade (17a) of trimming die (17) against the peripheral area (1a) after the heating and softening so as to press the one plate member (4) of the pair of plate members (3,4) against the other plate member (3) and performing not only mutual abuttal and fusion bonding of the pair of plate members (3,4) but also die cutting of laminate (19) from the laminated material (1).
