Abstract
A driving gear assembly for a double helix extruder. The assembly includes a multiple power path from a transmission gear to produce synchronism in the extruder helix shafts. The structure of the gearing enables a simple adjustment of the proper mesh of the extruder helices when mounting the gearing by mere disengagement and re-engagement of a (normally not disengageable) tooth coupling.
