ASPERSORES GIRATORIOS PARA APLICAR CAMADAS UNIFORMES A PECA SUSTENTADA POR TRANSPORTADOR

摘要

A rotary sprayer has a rotor centrally of a conveyor and spaced therefrom with its axis normal thereto. The rotor supports a series of spray heads so spaced from its axis as to establish arcuate paths for them across the conveyor as the rotor is rotated. The spray is discharged to coat the work carried by the conveyor as the spray heads cross the conveyor and during such crossing their travel relative to the arcuate paths is so varied that the thickness of the deposited layer is substantially uniform wherever applied. The rotor has a chamber through which the spray material passes and which provides an air cushion absorbing momentary pressure increases occurring as the valves of the spray heads close and minimizing pressure drops as valves open.
