<p>A machine for inspecting containers has a belt drive having upper (22) and lower (24) pairs of belt drives. Each belt drive has its own motor, and each opposed pair of belt drives can be relatively horizontally displaced and, as a unit, can be displaced vertically so that 1. the upper drive belt pair (22) can be raised clear of the lower drive belt pair (24); 2. the lower drive belt pair (24) can be separated and lowered to an out of the way location; and 3. the upper drive belt pair can then be lowered to be the only belt pair engaging a small container (12B). <IMAGE> <IMAGE></p> |
