ABSTRACT:
A device for braking advancing packages being transferred on a conveyer including a pair of rubber tubes of a predetermined length having flat surfaces, the tubes being inflated toward the packages being conveyed so that the tubes interpose and stop the packages. The pair of rubber tubes can be inflated so that they expand in an upwardly inclined direction in order to slightly lift the packages above the conveyer surface. Each of the rubber tubes are provided along the conveyer and are inflated with air. In addition each rubber tube has a flat braking surface, a reinforcing part at the back of the braking surface for maintaining the flatness of the braking surface, attaching wall part and a hollow section between the braking surface and the attaching wall part so that the rubber tube is normally small and narrow, but can be enlarged when inflated with air.
