Abstract
The invention relates to a device for feeding molten plastic extrudates which emerge from dies to a discharge channel having a cooling water inlet which follows the dies, in which device the dies are arranged in at least two rows, in such a manner that in the discharge direction strands from one row and the other row are guided alternately, next to and at a distance from one another, in which device two collection channels, which are arranged one above the other, are interposed between the dies and the discharge channel, in such a manner that the extrudates emerging from one row of dies are in each case fed to the discharge channel as a group via a collection channel, the individual extrudates of the two groups meeting one another in an intermeshing position alternately and next to one another on the discharge channel and being guided onward by the latter.
