Abstract

Melt conductor (1), in particular melt distributor or melt mixer, for an extruding die (2) of an extrusion facility (3), having a melt conductor block (4) with a multi-channel system (5), the multi-channel system (5) being arranged so as to extend three-dimensionally inside the melt conductor block (4) and having at least one input (6) and at least one output (7) for polymer melt, between one input (6) and one output (7) fluidically connected to the input (6) several branchings (8) arranged in series and several levels (9a, 9b, 9c) of sub-branches (10) being formed over several levels (12a, 12b) of divided melt channels (11a, 11b), m melt channels (11a) of the a^th level (12a) with x^th local cross-sections and n melt channels (11b) of the b^th level (12b) with y^th local cross-sections being present, wherein n>m if b>a, the y^th local cross-sections of the melt channels (11b) of the b^th level (12b) being smaller than the x^th local cross-sections of the melt channels (11a) of the a^th level (12a),
