Method/apparatus for making fiber-filled cushion

摘要

Method and apparatus for quickly, and substantially uniformly, heating and cooling a bed of polymeric fibers having high melting point and low melting point fibers therein for softening the low melting point fibers and bonding them to the high melting point fibers to form a seat cushion. Hot and cool gases are flowed through the bed of fibers to effect the heating/cooling.
