Cases of 384 CONVEYORS AND ELEVATORS FOR PACKED MATERIAL bottles or cans, both solid and open bottom, are handledthrough the processes of packing, washing, filling and ship-ping. , Close roller centers, from 3 in. to 4 in., are required onaccount of the height and relatively small base of the lengths of 14 in. or 16 in. are recommended to ac-commodate the largest cans. For this service sl^el rollersare much better than wood. Because of the shape of thecan side-guards are practically essential. These may beomitted at loading and unloading points to facilitate the tions. With ball-bearings, grades of from 3 per cent to 5per cent are usual for smooth bottom cases. The packing-table section may well be set level, and the filled boxes. Weighing on Gravity Conveyor handling. For cans, grades of from 5 per cent to 8 percent are usual, with a ball bearing conveyor. As far as possible, can conveyors should be kept close tothe floor to save labor in lifting the cans. Because of theextensive use of water for purposes of sanitation the bear-ings require more attention for oiling and cleaning than forthe gravity conveyor used under ordinarily dry a scale section is used it must be kept separate fromthe fixed sections adjoining. Also, to prevent inaccuracy inthe operation of the scale, special care must be taken tokeep it free from accumulations of foreign- matter whichwould affect the weighing.
