A vacuum forming machine has a machine frame and a forming station which includes a tensioning device for clamping a thermoplastic sheet blank to be deformed into an article, a bridge and a positive mold carried thereby. The bridge is vertically displaceable together with the positive mold between an inoperative position in which the positive mold is spaced from a location where the blank is clamped by the tensioning device and an operative position in which the positive mold is in an operative, contacting relationship with the blank. The positive mold is vertically displaceable with respect to the bridge between the operative position and a transfer position in which the article formed on the positive mold is transferred therefrom.
