Abstract: A contact toaster has a housing with a product inlet, product outlet and at least one toasting chamber defined in the housing. A heated platen is mounted in the housing and has a platen surface arranged for toasting the food products. A flexible endless belt, which when rotated, is arranged to pass the food products in a toasting path along the platen between the belt and the platen. An infinite controller acts to selectively displace the belt to adjust the distance between the belt and the platen to any value between minimum and maximum distance limits to accommodate food products of different widths. A guide is situated between the belt and the infinite controller so that the controller is in contact with at least one area of the guide.
