Abstract
An apparatus for precision linear positioning of material along a frame, having carrier means for carrying the material juxtaposed above the frame, means for linearly moving the carrier means along the frame having a plurality of pneumatic cylinders each having an extendable and rectractable piston, the cylinders connected to each other in a series and including a first end pneumatic cylinder attached to the frame and a last end pneumatic cylinder attached to the carrier means, such that the carrier means is moved by the amount of the cumulative extension and retraction of the pistons, stopping means associated with each the pneumatic cylinder for limiting the extension of each the piston, and means for providing a controllable amount of air to each pneumatic cylinder to selectively control extension and retraction of each piston.
