ABSTRACT:
A method of continuously manufacturing and curing in-line a sheet of ethylene-propylene diene monomer to form an EPDM roofing membrane. The method includes the steps of forming a continuous sheet material of ethylene-propylene diene monomer and then continuously heating and pressing the sheet material to partially cure the sheet material and remove any voids within the sheet material. The partially cured sheet material is then continuously fed through a curing oven to fully cure the sheet material to form EPDM roofing membrane.
