Device for providing untreated narrow side of wooden particle board for surface treatment, has reverse roll that is rotated to apply paint, and is cleaned so that optimum state of roll with board narrow side is maintained

摘要

The floating roller (R) and conveying belt (T) conveys a board (P) linearly and continuously in a flow path. A grinding and cleaning unit performs grinding and cleaning of untreated narrow edge (L) of board. An applying unit coats paint on board narrow side while a reverse roll (5) is rotated at suitable speed. A removing unit removes excess coating from longitudinal edges (B1, B2) and edges (C1, C2) of painted narrow side, and a drying unit dries and cures coating film. The roll is cleaned by paint scraper (6) so that optimum state of roll with board narrow side is maintained.
