Apparatus for producing a set of mutually distinguishable flooring tiles

Apparatus for producing flooring tiles comprising

• a mold having upper and lower stamps,
• first supply means for supplying a first quantity of material for a ground layer of the flooring tile on the lower stamp and
• second supply means for supplying a second quantity of material on the ground layer on the lower stamp for an upper layer of the flooring tile, whereby said second supply means is comprised of a plurality of containers holding differently colored materials for said upper layer, a slide with a sieve thereunder, said slide being movable between a starting position where it is in communication with the discharge of said containers and a depository position over said lower stamp, said first and second quantities of material define a substrate and
• third supply means for supplying a third quantity of material onto said substrate comprising a drivable conveyor belt which collects said third quantity of material from one or more strewing bins as a portion of the belt is horizontally displaced from a first position to a second position above said lower stamp and which thereafter deposits said third quantity of material from a discharge end of said conveyor belt onto said substrate by driving said conveyor belt as the portion of the belt is horizontally displaced back toward said first position and further comprising one or more metering rollers for depositing said third quantity of material onto said belt from said strewing bin.
