    摘要: A method and apparatus in which one or more positive temperature coefficient thermistors heat air for application to printed stock in a printing press. The apparatus is preferably mounted on the press, located a short distance above stock traveling from a printing station to a delivery station. The apparatus directs air flow downward over or through the PTC thermistors and into contact with the printed stock. Preferably, variable-speed fans provide forced airflow for this purpose. The rate of heat output of the apparatus may be varied. The preferred PTC thermistors are supported on a frame of adjustable or variable length adapted to span the width of various transfer beds or printing presses to facilitate installation of the apparatus on presses of varying dimensions and configurations.
