Apparatus for the distribution of particulate material upon a surface

摘要

An apparatus for the distribution of particulate material including glass beads onto one of freshly applied paint or polymer material applied to a surface, includes a housing having defined therein an upper chamber for the receipt of particulate material and a lower chamber including a downwardly directed opening. The housing additionally has feeding control means positioned between the upper chamber and the lower chamber to allow the particulate material to pass in a controlled manner from the upper chamber to the lower chamber. At least one distribution grid is positioned in the lower chamber through which substantially all of the particulate material to be applied onto the surface passes to the downwardly directed opening.
