<p>A conveyor chain (1), shown in the figure, has links interconnected by pivot pins (3), each passing through legs (2a, 2b) of one link and through generally C-shaped annular portion (2c) of an adjacent link (Fig. 3) said portion (2c) being seated between the legs (2a, 2b). The pivot pin (3) passes through part-cylindrical core (4) seated with annular portion (2c). Each C-shaped portion (2c) has integral legs (2a and 2b). Each core (4) is integrally formed with disc element (5) seated in a curved stepped guide recess (6) of the adjacent link (2). The upper surface of each disc element (5) is arranged in the same plane as the upper surface of the adjacent link (2). As the chain (1) travels on a flat surface the upper surface of the chain is flat with disc element (5) covering the gaps (7 and 8).</p> |
