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.
Definition of Platelets. Platelets are tiny cell fragments that are found within our blood. They originate in the bone marrow as pinched-off pieces of larger cells. Platelets are neither smooth nor round, but are shaped more like paper that has been ripped into tiny bits. They spend much of their time cruising through the bloodstream alongside their red and white blood cell counterparts.
