ABSTRACT:
A method for producing a foamed innerspring unit using a foamable reaction mixture that will provide a flexible foam using diphenylmethane diisocyanate and at least one polyol is provided. The process comprises the steps of preparing the foamable reaction mixture, spraying the foamable reaction mixture into a tray, loading an innerspring unit 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 unit. The process is especially well suited to be carried out on a continuous conveyor. A novel foamed innerspring unit is also provided.
