  • Conveyor chain
    Patent number: 6068112
    Abstract: A reduced friction conveyer chain is used for conveying aluminum cans, glass bottles, PET bottles and other objects in a conveyer chain system where such objects are produced continuously. The conveyer chain is especially useful in the system where the objects being conveyed are slid on the surface of the chain and relatively thereto. Since the kinetic friction coefficient of the outer surfaces of the links, which constitute the conveyer chain and on which the objects to be conveyed are put, is reduced, the slidability of the links is improved, and the bottom surfaces of the objects being conveyed are prevented from being scratched.
