Abstract
A transport device for boards having a sensitive surface, especially for wet-coated circuit boards, comprises, within a common housing, a lacquering station and, arranged above the latter, a drying region. For transporting the boards (2) through the drying region holders (3) are provided which comprise at least two bars (30) each having rows (31,32) of prongs extending from a bar (30) in a "V" shape and arranged in the form of a rake. The free ends of the prongs of the one bar point towards the free ends of the prongs of the other bar. The bottom ends of the holders (3) are open. For supporting the bottom ends (2b) of a board (2) that is being transported in a holder (3), the transport device is equipped with a supporting device (12) that is movable synchronously with the holders (3).
