摘要：In a process for the continuous manufacture of a conveyor belt with rubbercovering layers and with a reinforcing insert of longitudinal wire ropes, the wire ropes aremaintained in tension and covered with an upper and lower covering layer of rubber. Theraw belt constructed in this manner is then vulcanized by means of exposure to pressureand heat in a rotating installation. The innermost rubber cover layer in the radial directionis scorched prior to its placement on the outer cover layer and the longitudinal steelwires.
An apparatus for the continuous manufacture of a conveyor belt with cover layers ofrubber and with a reinforcing insert of longitudinal steel ropes has an extruder- calenderarrangement (2, 4 and 3, 5, respectively) each for the production of the lower and uppercover layer (11, 12). At least one doubling installation (15, 17; 22, 23) is provided for thecombining of the cover layers (11, 12). Between the extruder-calender (2, 4) producingthe cover layer (11) resting on the press drum (16) during the finish vulcanizing process,and the doubling station (22, 23), a heating device (24, 26) is provided for the heating ofthe cover layer (11).
