ABSTRACT:
A strand pelletizer for cutting thermoplastic strands into pellets is provided. The strand pelletizer has a housing that includes a base, a pivotable cover, and a moveable end wall. The pivotable cover and the movable end wall may be opened without the use of tools to provide access to the interior of the pelletizer cutting chamber. The movable end wall is both slideable and pivotable over a fixed dowel pin within the housing base. The moveable end wall houses the feed rolls for the pelletizer and also houses the strand inlet to the pelletizer. After the cover is raised, the moveable end wall may be pivoted away from the cutting chamber to permit cleaning of the interior of the cutting chamber, particularly the critical area below the lower feed roll of the cutting chamber.
