ABSTRACT:
An overwrap machine for sealing packaging for a foodstuff comprises a conveyor belt, heating elements, and pluralities of modules holding rollers which contact the packaging as individual foodstuffs are conveyed by the modules. The modules, and thus the rollers, are heated by the heating elements. There are two different roller types, which are the cylindrical first rollers and the ellipsoidal second rollers. The pluralities of rollers include substantial numbers of the first rollers with fewer numbers of the second rollers interspersed therein. The ellipsoidal second rollers are effective to insure the sealing of the ends of the foodstuff being overwrapped by bearing against the unsealed ends as each foodstuff traverses the gap between opposing second rollers.
