Abstract
A thermoformer apparatus has sheet supporting rails which are divided into sections hinged together to facilitate widening of the spacing between the rails with adjuster drive mechanism as the sheet moves through an oven to eliminate sagging of the sheet as it becomes heated. Thermoformer chains are driven by a pair of independently operable servo motors each associated with a respective thermoformer chain.
