  • Patent number: 4078032
    Abstract: A method and apparatus for fabricating continuous lengths of cleated belting. The method includes the steps of feeding a continuous length of belting base material alternately forwardly with or over and backwardly with, a cleat positioning mold first into, then out of and then through the space between vertically moveable press platens. The cleats are assembled with and cured to the base material in longitudinally adjacent groups. Each group of raw cleats and a corresponding section of the base material is moved with the mold forwardly into the press, cured, and then moved rearwardly with the mold out from between the press platens. The cured section is separated from the mold. A new group of uncured cleats is positioned for a succeeding section. The base material, including the cured section, is moved forwardly relative to the mold until the last cured cleat of the group of cured cleats is positioned at the first of the cleat positions of the mold.
