Abstract
A sublimation furnace has a first endless conveyor belt extending along a first axis through the furnace, with a chamber extending above and along that first conveyor belt. Vacuum trays placed on the first belt have products abutting sublimation images to be transferred to the product as the trays pass through the furnace. The furnace has a first sidewall with a slot extending along the sidewall and along the first conveyor belt. A second endless conveyor belt extends along but offset from the first axis. A plurality of vacuum pumps are connected to the second conveyor belt and move with that belt, with each pump connected by a hose passing through the slot during use of the furnace to a different vacuum tray on the first conveyor in order to evacuate the vacuum trays and press the images against the product for sublimation transfer.
