  • Patent number: 5533315
    Abstract: An apparatus checks a closure on an end of a bag having loosely packed goods contained therein. A first conveyor extends the length of the apparatus. Second and third conveyors are positioned adjacent one side of the first conveyor. A gap is defined between the second conveyor and the third conveyor. Adjacent portions of the first conveyor and second conveyor are coplanar to define a first surface moving in the same direction at the same speed that fully supports the bag moving thereon. Adjacent portions of the first conveyor and the third conveyor are coplanar to define a second surface moving in the same direction at the same speed as the first surface that also fully supports the bag moving thereon. The first conveyor partially supports the bag such that the end thereof and a portion of the loosely packed goods contained in the bag are unsupported by the first conveyor in the area of the gap.
