Abstract
A machine for dusting a shape with particulate matter, the shape being a profiled roof tile including raised patterns extending in the lengthwise direction thereof, and including raised portions laterally separated from hollow portions by sloped portions, the tile having a predetermined width, and being preferably corrugated, the machine including a dusting element forming a homogeneous linear curtain of particulate matter falling across the width of the tile, the tile travelling longitudinally under the linear curtain. Deflectors of the curtain are arranged above the tile to intercept the particulate matter above the areas at the bottom of the sloped portions and redistribute the intercepted particulate matter towards an intermediate level of each corresponding sloped portion in order for the amount of particulate matter on the surface of the plate ultimately to be substantially homogeneous after a portion of intercepted particulate matter has slid towards the bottom of the sloped portion.
