ABSTRACT:
The increasingly high standards of consistency and uniformity demanded of cold feed rubber extruders are met by providing notches in the flights of the screw at least in the feed-inlet of the extruder. The notches are at a lead-angle greater than that of the extruder screw flights, so to pull the rubber and advance it positively. Throttling means are used to adjust the amount of squash-back and there is an independently variable-speed drive for a feed roller in the feed inlet.
