ABSTRACT:
An apparatus for the production of long-chain polymers, especially polyesters, is designed with several shafts arranged vertically in ring fashion inside a common housing, with parallel axes and driven in equal direction, each of which carries a number of disk-shaped processing elements arranged axially in a row and in parallel planes, with which adjacent shafts mesh, leaving narrow gaps of predetermined width. These processing elements together with the shafts enclose at least one cavity that is under negative pressure and in whose area the processing elements are arranged in such a way that their circumferential surfaces are exposed. To allow for the processing of material that forms a foam during expansion, the arrangement is designed in such a way that the housing has a tubular housing liner surrounding the shafts which with its cylindrical inner wall reaches tangentially to the circumferential surfaces of the processing elements of the shafts, leaving open a narrow gap of defined width, and which is rotatably mounted onto two coaxial stationary housing sections that seal and close off the ends of the housing liner. The housing liner is coupled with a drive arrangement that provides it with an oscillating rotational movement.
