Apparatus for continuous mixing of two liquid agents to obtain a foamed synthetic product

Claim 1

Apparatus for continuously forming a foamed synthetic resin product by projecting aqueous synthetic resin solution into a foam material comprising a. first conduit means, said first conduit means including a mixing chamber, b. second conduit means generally centrally located within said first conduit means forming an annular passage between said first and second conduit means for conducting said foam material along a path contiguous to said second conduit means into said mixing chamber, said second conduit means being adapted for conducting said synthetic resin solution, c. a nozzle at the end of said second conduit means communicating with said mixing chamber, d. orifice means in said second conduit means upstream of said nozzle for forming a high-speed stream of said synthetic resin solution as it passes therethrough, and e. impingement means in said second conduit means between said orifice means and said nozzle, a passage being provided around said impingement means within said second conduit means, f. whereby said aqueous synthetic resin solution is first atomized by said impingement means, and the atomized solution passes along said passage and is further atomized when passing through said nozzle, said impingement being isolated isolated from contact with said foam material preventing accumulation of foam product thereon, and said atomized synthetic resin solution comes into immediate contact with said foam material upon passing through said outlet.
