Abstract
An extruder worm for processing elastomers or thermoplastics characterised by these being along part of the length of the worm between two threads defining the track of the worm, a more or less parallel ridge running in roughly the same direction and having at max. the same height as threads and, looking on the direction of the feed, at the start of the parallel ridge, a cross rail blocking the channel between the parallel ridge and the one thread, as well as at the end of the parallel ridge a further cross rail, blocking the channel between the parallel ridge and the second worm thread.
