METHOD OF MANUFACTURING FOAMED INNERSPRING UNIT AND PRODUCT

摘要

A method for producing a foamed innerspring unit (20) using a foamable reaction mixture including diphenylmethane diisocyanate that forms flexible foam layers (22, 24) is provided. The process includes the steps of preparing the foamable reaction mixture, spraying the foamable reaction mixture into a tray (10), loading an innerspring unit (26) into the foamable reaction mixture-containing tray and permitting the foamable reaction mixture to rise to form a foam that is at least partially adhered to the innerspring unit. The process is especially well suited to be carried out on a continuous conveyor. A novel foamed innerspring unit is also provided.
