METHOD OF MANUFACTURING FOAMED INNERSPRING UNIT AND PRODUCT.

摘要

we describe a process for making foam objects inside springs (20) from a reaction mixture containing diphenylmethane diisocyanate, which can be transformed into foam and form flexible foam layers (22, 24).the process consists of preparing the reaction mixture, the mixture of foam, spray tray (10) to the internal spring element (26) in the bath containing the reaction mixture and foaming the mixture to harden to form a ca that is, at least in part, to the spring element.the process is particularly well suited to the manufacture in a continuous flow. also described are a new subject in foam springs.
