Abstract
A transport and stacker system in which the articles being transported are propelled in their path of travel by the moving magnetic field of a linear induction motor. The magnetic field also functions to attract the moving articles toward the linear motor and in order to overcome this attracting force and air bearing is provided. The air pressure acting against the attracting force is just sufficient to move the articles a slight distance away from the linear induction motor so that the articles move in the path of travel while suspended in air out of contact with the physical surface of the motor. When the desired position is reached, the article is dropped on a stack by deenergizing the magnetic field.
