MELT CONDUCTOR FOR AN EXTRUSION TOOL OF AN EXTRUSION SYSTEM, EXTRUSION TOOL, EXTRUSION SYSTEM AND METHOD FOR OPERATING AN EXTRUSION SYSTEM OF THIS TYPE

摘要

The invention relates to a melt conductor (1), in particular a melt distributor or melt mixer, for an extrusion tool (2) of an extrusion system (3), comprising two or more melt conductor blocks (4a, 4b) and a multi-channel system (5), wherein the multichannel system (5) is arranged, extending three-dimensionally, within at least one of the melt conductor blocks (4a, 4b) and has at least one inlet (6) and at least one outlet (7) for polymer me wherein a plurality of branchings (8) arranged one downstream the other and a plurality of generations (9a) of further branchings (10) of melt channels (11a, 11b), which melt channels are divided among a plurality of generations (12a, 12b), are formed between an inlet (6) and an outlet (7) fluidically connected to the inlet (6); wherein m melt channels (11a) of a-th generation (12a) having x-th local cross-sections and n melt channels (11b) of b-th generation (12b) having y-th local cross-sections are provided; wherein n > m, if b > a; wherein the y-th local cross-sections of the melt channels (11b) of b-th generation (12b) are smaller than the x-th local cross-sections of the melt channels (11a) of a-th generation (12a). The invention further relates to an extrusion tool, to an extrusion system and to a method for operating the extrusion system.
