ABSTRACT:
Each side frame of a roll conveyor includes a series of holes in which the projecting ends of the roll axles are selectively mounted according to the desired spacing between rolls. One side frame forms a chain box which partially encloses the chain drive of the roll. Separate plates are provided to fully close the box. They are in certain lengths whereby only several groups need be provided for their use in closing the chain box of any conveyor of whatever roll spacing it may have, within limits.
