A platen (or platten) is typically a flat metal (or earlier, wooden) plate pressed against a medium (such as paper) to cause an impression in letterpress printing.he platen sits between two steel rolls which deliver the moving force to the sanding belt. Sanding heads with a platen are used on finish sanding with papers of finer grits, when the coarser ones are typically used with contact drum type sanding heads. Stock is fed into and out of the machine on a conveyor belt.
Cell plate is the structure found inside the dividing cells of terrestrial plants and some algae. It develops in the middle plane of the cell separating two daughter cells during cell division. In animal cells, cytokinesis is carried out by the formation of cleavage furrow but in plant cells it is by the formation of cell plate. Compare: cleavage furrow.
