Abstract

A roller track is arranged in sections in that individual groups of carrier rollers can be selectively drivingly connected to and disconnected to and from a drive belt for section stop-and-go operations permitting a buffer location for each section, there being vertically displaceable belt rollers for engaging the belt to obtain driving connection to and disconnection from carrier rollers. The track includes a plurality of control rollers, control bars and control cams. The belt rollers are eccentrically mounted in the control rollers such that depending upon the angular position of the control rollers the respective belt rollers are lifted or lowered for engagement with or disengagement with the belt.
