Abstract
A heating device for heating merchandise, especially printed boards, comprises a feeding device provided in front of a least one heating line in the transport direction of the merchandise and a discharge device provided behind the heating line in the transport direction, wherein a number of heating zones/devices and/or cooling zones/devices or the like are associated with the heating line. To improve a heating device of the aforementioned type by increasing the throughput of merchandise in a simple manner, at least two heating lines are disposed on top of each other, to which merchandise can be separately fed by the feeding device from a horizontal transport level, and the merchandise can be separately discharged from the heating lines by the discharge device from the heating lines back into a horizontal transport level.
Claims35
