ABSTRACT:
A spider in an extruder head has a plurality of internal plastic flow passages extending axially through the spider and a spider leg between each flow passage. Each spider leg has upstream and downstream spider leg parts. The upstream part is a flow splitter which splits flow of plastic along the extruder to the spider leg into a plurality of independent plastic streams. The downstream part of the spider leg has a plurality of flow guides staggered at different radial depths in the spider leg with all of the flow guides being directed at one another to guide the bonding of independent plastic streams.
