Abstract
An apparatus for calibrating hollow chamber sheet extruded lines out of thermoplastic resin includes a vacuum housing and a planar intake area at a first end of the vacuum housing. The planar intake area is configured to receive the extruded line. Support rollers within the vacuum housing are configured to support the extruded line. The extruded line exits the vacuum housing through a planar outlet area located at a second end of the vacuum housing opposite the first end.
