Abstract: A method and apparatus are described for stabilizing a thin, relatively frictionless conveyor belt against lateral movement. The typical belt is made of fiberglass and Teflon-coated and is mounted on rollers, one of which is a drive roller. The drive roller is equipped with at least one ridge disposed circumferentially adjacent an end thereof and the belt forms a track which receives the ridge as the roller rotates. The track, in turn, has mutually spaced holes along its length. The holes are disposed at least so that two contact the roller during each revolution, and the diameter of the ridge is less than one-half of the diameter of the hole. This tracking device then will maintain the belt during operation against lateral movement relative to the rollers.

Abstract: A belt grill is described herein for continuously cooking fast food products on a conveyor formed of counter-rotating heat conductive belts. The belts are heated by platens disposed above and below whereby a run of the belts passes in heat conductive relationship between the platens, and the food to be cooked is placed in the nip between the rotating belts. The device further includes means for tensioning the belts which can be automatically released by increasing the distance between the platens whereby when the distance exceeds a predetermined maximum, all tension on both belts will be released so that the belts can be quickly removed for cleaning or replacement. The belts are preferably Teflon coated fiberglass and may be disposed at an angle to the horizontal to facilitate grease removal from the cooking process.
