Abstract
An adjustable roller conveyor module includes a first support structure comprising first and second laterally spaced, longitudinally extending frame members. A first roller set supported by the first support structure includes rollers rotatable about lateral axes equi-spaced in accordance with a predetermined roller-axis spacing. A second support structure is carried between the first and second frame members of the first support structure for longitudinal reciprocation between fully retracted and extended positions. The second support structure supports a second roller set including rollers rotatable about lateral axes coplanar with the axes of the first roller set and equi-spaced in accordance with the predetermined roller-axis spacing. Selected rollers of the first roller set are removable to accommodate retraction of the second support structure. A set of extension apparatus is extendable beyond each end of the conveyor module and reciprocable between fully retracted and extended positions separated by a distance corresponding to at least one half of the roller-axis spacing.
