Abstract
A positioning assembly comprises a base having a pair of taller projections and a pair of shorter projections on its surface. The positioning assembly is placed between a pair of belts which form a conveying assembly, so that the taller projections receive a sheet material which is conveyed along the belts. The positioning assembly is positioned at a middle position in which the taller projections project above the belts, whereby the taller projections receive the material. Receiving the material, the positioning assembly is elevated to a high position where all the projections including the shorter one project above the belts, whereby the material is held on the base. The material is processed with being rotated at the high position. Then the positioning assembly is lowered to a low position where all the projections are below the belts, whereby the material is delivered again onto the belts to be conveyed to the next process.
