Abstract
A wheeled tooling cart for a thermoformer machine enabling quick and easy removal and installation of upper and lower tooling plates from their respective platens. The tooling plates are held on upper framework on the cart, which are removed one at a time with the cart in position adjacent the machine with one and the opposite end successively. The tooling plates are held in position on the cart for reinstallation when the cart is appropriately repositioned with respect to the thermoformer machine. An elevator mechanism allows an upper framework having attachment brackets and rails for holding the tooling plates to be raised and lowered on a wheeled lower framework to move the attachment brackets and rails into proper position for attachment and removal of the tooling plates.
