Web surface treating apparatus

摘要: A five roll calendar apparatus includes rolls mounted in a common horizontal plane, including three heated with first and second covered rolls. Each an inner rigid core having outer finished surface. plurality of grooves are formed by machining the face thin sleeve is shrunk fit onto to seal establish heat transfer passageways. The size passageways, separating lands shell thickness such that temperature at surface essentially constant over portions cavity adjacent body. wall establishes short time response for correcting web. center rotatably fixed other individually loaded toward controlling nip pressure. suitable slide supports. end torque shaft which provides high degree squareness loading. squeezes air from Grooved guide maintain proper web flatness. Heat sensing units located monitor each connected closed loop control roll.
