Method and device for spinning material consisting of at least two polymeric components

摘要

In the method the mutually divided molten polymeric components (R, G, Y, B) are introduced into the spinning die (32) with extrusion outlets (53) to slag the endless filaments (34). Each of the mutually divided polymeric components (R, G, Y, B) is at first divided to be available as an individual polymeric component (R, G, Y, B) for each back inlet (52) of the spinning die (32), and then there is realised the selection of the polymeric components (R, G, Y, B) available for each of the back inlets (52) to be transferred into the related back inlet (52) of the spinning die (32) to subsequent slagging in the form of endless filament (34) from the extrusion outlet (53) of the spinning die (32) and from the extrusion outlets (53) the set of endless filaments (34) is slagged, made of various polymeric components. In the device there is in the direction of the flow of polymeric components in front of spinning die (32) and behind the receiver (101) placed a dividing mechanism (100), containing devices (102, 103, 104, 105) for dividing of singular individual partial flows (15, 20, 24, 28) of the polymeric components (R, G, Y, B) into the spinning die (32). The outlets (106, 107, 108, 109) of the dividing mechanism (100) are placed opposite to the related back inlets (52) of the spinning die (32) and between the outlets (106, 107, 108, 109) of the dividing mechanism (100) and spinning die (32) there is placed a selecting device (200) to selectively closing and opening of the connections between the outlets (106, 107, 108, 109) and the back inlets (52) of the spinning die (32).
