Method and apparatus for grooving the barrel of a plasticating machine
Colby September 4, 1990
Abstract
A method and apparatus for cutting grooves onto the interior surface of the barrel of a plasticating machine in order to increase the friction against sliding unmelted resin particles. The helical screw is removed from the barrel without removing the barrel from its operating site. A grooving device is transported from a remote location to the plasticating operation site and mounted within the barrel with a portion protruding from the barrel. A brance is attached to the end of the barrel to help support the grooving device. Periodic adjustments are made to the grooving device by manual or automatic manipulation of the grooving device.
