<p>A conveyor chain (1) for transporting articles, which has an unusually continuous bearing surface for the articles, comprises a plurality of links (2), in which each link defines a bearing surface (3a) for the articles to be transported, each link (2) being articulated to an adjacent link (2) in the chain by means of a pin (8) and being pivotable relative to the adjacent link (2) by means of a sleeve (11) which has an axis (Y-Y) perpendicular to the bearing surface (3a) and is rotatable coaxially about a pivot (13) fitted on the pin (8) and comprising a plate-like head (17) extending through the link (2) to the level of the bearing surface (3a) and having a portion (18) shaped like a segment of a circle with a base (18b) extending in the direction of the width of the conveyor chain, and a portion (20) having a side (20a) adjacent the base (18b) of the circular-segment-shaped portion (18) and an opposite side (20b) which is concave and fits the circular- segment-shaped portion (18) of the plate-like head (17) of the pivot (13) of the adjacent link (2) in the chain. <IMAGE></p> |
