<p>A rubber sheet forming apparatus (1) comprising a rubber extruder (2) composed of upper and lower rubber extruder main bodies (4,5) for kneading and sending out forward rubber, a main body block (6) mounting the upper and lower rubber extruder main bodies (4,5), an upper head (9) and lower head (10) coupled to the main body block (6) so as to form a nozzle port (7), and a roll forming device (3). The main body block (6) comprises a base part (12) having an upper rubber passage (16) and a lower rubber passage (17), and a protrusion part (14) projected at the front surface (13) of the base part (12) to reduce the thickness toward the forward side. The upper head (9) and lower head (10) are disposed on the main body block (6) so as to form an upper and lower rubber paths (21,22) and the nozzle port (7) communicating with a joining part (23) joining the upper and lower rubber paths (21, 22). The roll forming device (3) has an upper and lower rolls (51,52) disposed ahead of the nozzle port (7) and pressing the overlaid rubber extruded from the nozzle port (7).b <IMAGE></p> |
