Method and apparatus for accent coating of lap panels

A method of coating panels having a plurality of embossed panel portions extending lengthwise thereof in generally parallel planes offset from one another to provide a step between the adjacent embossed panel portions, comprising the steps of moving said panels lengthwise along a predetermined path, and, during movement of said panels along said path, applying a liquid coating to said panel portions and steps of said panels, wiping only some of the liquid coating thus applied from said embossed panel portions but not wiping said steps, and withdrawing excess liquid coating thus applied from said steps by a flow of gas over and closely adjacent to said steps.

Apparatus for coating panels having a plurality of embossed panel portions extending lengthwise thereof and at least one transition zone connecting the adjacent embossed panel portions, compising means for moving said panels lengthwise along a predetermined path, a roll, means supporting said roll in a position extending across the path of panel movement, said roll having a plurality of roll portions respectively juxtaposed to said embossed panel portions and of appropriate radius to contact said embossed panel portions but not to contact said transition zones, means for applying a liquid coating to such embossed panel portions and transition zones of said panels upstream of said roll, means for reverse rotating said roll to wipe some of such liquid coating from said embossed panel portions without wiping said transition zones, and means for producing a flow of gas over and closely adjacent to said transition zones to withdraw excess liquid coating therefrom.

Apparatus for coating panels having a plurality of embossed panel portions extending lengthwise thereof in generally parallel planes offset from one another to provide a step between the adjacent embossed panel portions, comprising means for moving said panels lengthwise along a predetermined path, a roll, means supporting said roll in a position extending across the path of panel movement, said roll having a plurality of cylindrical roll portions respectively juxtaposed to said embossed panel portions and of differing radius to contact said embossed panel portions, means for applying a liquid coating to such embossed panel portions and steps of said panels upstream of said roll, means for reverse rotating said roll to wipe some of such liquid coating from said embossed paneel portions without wiping said steps, and means for producing a flow of gas over and closely adjacent to said steps to withdraw excess liquid coating from such steps.

Apparatus for accent coating panels having a plurality of embossed panel portions extending lengthwise thereof in generally parallel planes offset from one another to provide a step between the adjacent embossed panel portons, comprising means for moving said panels lengthwise along a predetermined path, a roll, means supporting said roll in a position extending across the path of panel movement, said roll having a plurality of cylindrical roll portions respectively juxtaposed to said embossed panel portions, means for applying an accent coating to the embossed panel portions and steps of said panels upstream of said roll, and means for reverse rotating said roll to wipe coating from said embossed panel portions, the peripheries of said roll portions matching generally the contour of said panels except in the stepped areas thereof in order not to contact or wipe said steps, and vacuum means for withdrawing excess liquid coating from the steps of said panels.
