A method is provided for forming a contact toaster having a flexible belt. The method includes forming a flexible belt by applying at least one of a silicone rubber, a urethane rubber, and a fluoropolymer to a fabric reinforcement material having a first face and a second face, and forming ribs on the first face of the fabric reinforcement material. The ribs are formed from at least one of a silicone rubber, urethane rubber, and fluoropolymer. The flexible belt is attached to the contact toaster such that the ribs on the first face are configured to impart lateral force to objects to be toasted that are carried by the flexible belt. The flexible belt is attached such that it passes through a heating zone of the contact toaster.
