Abstract
An apparatus for removing plastic residues from parts of plastics processing machines includes a vessel which is closed in air tight manner by an end plate and contains heat transfer fluid. Immersing within the heat transfer fluid is a disk which is operatively connected to a vibrator so as to oscillate for improving the cleaning action. Placed on the end plate is a tubular casing box which is divided into a lower compartment which is essentially sealed off and in which the vibrator is accommodated and into an upper compartment which is open to the atmosphere. At least one pipe traverses the lower compartment for connecting the interior of the vessel with the upper compartment so that vapor and gases may escape through this pipe. A filter is arranged within the upper compartment for absorbing the vapor and gases to prevent the release of obnoxious gases.
