ABSTRACT:
An apparatus for dividing a continuously conveyed stream of shingled workpieces, such as bags or sacks, into leading and trailing parts has two consecutive endless belt conveyors. The downstream second belt conveyor is driven, during a dividing operation, at a higher velocity than the first upstream conveyor in order to pull the shingled stream apart. After the stream has been divided into the leading and trailing parts the second conveyor is driven at the same velocity as the first conveyor. To provide separation of the stream into parts consisting of an exactly predetermined number of workpieces, an intermediate endless belt conveyor is provided, which extends parallel to the trailing portion of the second belt conveyor and during the dividing operation revolves at a lower velocity than the second belt conveyor. The intermediate conveyor is provided with cams for arresting the leading workpiece of the trailing part of the shingled stream, against an upper pressure belt.
