ABSTRACT:
A conveyor for varied size and shape containers has a pair of feed screws mounted parallel to one another on opposite sides of a line of container travel. A mechanism is provided for moving the screws toward or away from one another in a manner to maintain an equal distance of each screw from the line of container travel. The screws are preferably formed with a helix having straight sidewalls that are at an angle of 90° to 100° to one another. In one embodiment one feed screw has a left hand helix and is rotated in a first direction and the other feed screw has a right hand helix and is rotated in a second direction opposite to the first direction.
