ABSTRACT:
Pre-cut square carpet samples are placed edgewise on the first of a stepped series of pairs of sample conveyor belts, the belts of each pair being separated to accommodate between them a power-operated beveler. An inclined sheet metal backing plate is provided adjacent each pair of the conveyor belts and has a cut-out through which another series of stepped belts operates immediately above each pair of conveyor belts in a plane at right angles thereto, the second series of belts spanning the spaces between the conveyor belts of each pair. Spring pressure bars lie immediately forwardly of and parallel to the belts of the second series and resiliently press the carpet samples into contact with the belts of the second series to assure firm contact of each edge of every carpet sample with the powered beveler as each sample passes thereover. At the downstream end of each pair of conveyor belts, each sample tumbles onto the next lowermost pair and in so doing rotates 90 degrees with the assistance of a provided air jet to present another edge of each sample to the next powered beveler.
