<p>A table for use in plastic forming machines, the table including a plurality of upstanding tubular support members arranged in a predetermined pattern, a plurality of alternately usable platform members, each such platform member being of a different size to support different vacuum molds and each being mountable on selected ones of the upstanding tubular supports. A plastic material clamping frame having readily adjustable side elements for varying the size of the clamping frame is arranged to be selectively positionable, at all variable sizes thereof, between selected tubular support members to thereby hold the edges of a sheet of plastic material along and beneath the edges of different vacuum forming molds mounted on a platform member supported by the tubular support members.</p> |
