A conveyor 12 includes an infeed/scanning section ( 18 ) and a cutting/outfeed section ( 22 ). Both sections have an endless belt ( 70 ) and ( 180 ) each driven by a friction drive roller ( 100 ) and ( 200 ). Adequate frictional load is applied between the endless belts and corresponding drive rollers by tension assemblies, each having a tensioning roller ( 86 ), ( 188 ) rotatably mounted on a pivot frame structure ( 112 ), ( 220 ) allowing the weight of the tensioning roller to be applied to the return run of the endless belts. Dampeners ( 130 ) ( 270 ) are integrated with the tensioning rollers ( 86 ) ( 188 ) to dampen vibrations in the endless belts ( 70 ) ( 180 ).
