Abstract
A roller conveyor having housings pivotally mounted below the rollers. Friction rolls rotatably mounted in the housings drive the rollers. The friction rolls are urged against the rollers with controlled pressure. A diaphragm or a spring can raise each housing to operative position to cause the associated friction roll to drive the associated roller. The pressure is controlled so that if one of the rollers is restrained, the associated friction roll can slip.
