Invention herewith described refers to the procedure for band conveyor roller segmental lining with rubber-metal segments, without disassembling the band conveyor rollers which is done with the use of industrially produced rubber-metal segments of the arc curved shape to follow the circular surface of the rollers, depending on the diameter of the rollers that are lined with the rubber-metal segments, which allows to replace individual segments or the whole roller lining when replacing the rubber-metal lining.The present procedure is done in three ways. According to the basic solution, on the sheet metal (10) of a segment (2), of the arc curved shape, the contact rubber layer for lining the roller (1) is applied by vulcanization and attached to its perimeter by arc spot welding (3). In the second solution one longitudinal metal profile (5) U-shaped, is pre-set on one side of each rubber-metal segment (6) with the shorter profile arm (4) shaped like an inverted letter Z, while longer arms ( 4, 5) of the profile placed against the roller (1) and attached to it by arc spot welding (3) and the rubber parts of the segment (6) are interconnected by vulcanization. In the third solution, metal sheets (8) of the segment (7) are longitudinally bend in the shape of a letter L, and then the contact rubber layer for the roller lining is applied by vulcanization with pre-incised grooves (9) in the shape of an inverted letter T toward the roll centre (1) and longitudinally along the metal surface of the roller (1), where the segments (7) with profiled metal sheet (8) are partially retracted into the grooves (9) and then fastened with sheet metal (10) to the roller (1) by arc spot welding (3).
