ABSTRACT:
A continuous drier for flat piece material, especially for liquid-coated printed circuit boards, and the like, comprises a heatable drier housing and a transport path that ascends in the housing and, after passing an upper turning point descends again. Secured to an endless chain that extends substantially vertically are carriers for the piece material to be transported, which carriers project outwards from the endless chain. The drier also comprises a supply duct for drying air for the piece material to be dried. The supply duct is so arranged that an airstream supplied by it flows over the piece material transversely to the direction in which the carriers project from the chain links.
