摘要:
A shaft support member of at least one (12) of a pair of kneading rolls (11, 12) opposing each other with a very small gap between them and forming a valley portion, in which a resin charged from above stays, is connected to a driving source which changes a shaft gap, and a pair of weir plates (15b) having a shape substantially in conformity with the shape of the valley portion and adjacent to the kneading rolls (11, 12) without coming into contact with them are connected to a moving driving source in the axial direction of the kneading rolls (11, 12) while being spaced apart by a substantial effective width of the kneading rolls (11, 12). A sheet frame supply source supplies sheet frames (40) one by one toward the valley portion. Conveyor means (57, 58) for an inspection sheet is disposed at a discharge position of the inspection sheet, which is formed by bonding a resin sheet (37) kneaded and formed by a pair of kneading rolls (11, 12) and bonded to the sheet frame (40), and a table (59) for the inspection sheet and an imaging apparatus including a light source (64) and a video camera (65) are successively disposed downstream of the conveyor means (57, 58).
