摘要

Foam generating apparatus comprises a liquid reservoir (1) and a pump (3) for re-circulating liquid from said reservoir through a closed circuit back to said reservoir, said closed circuit including valve means (5) responsive to at least the linear speed of a fabric to be treated with foam and serving to divert liquid from the closed circuit to a foam generator (8) wherein it is admixed with air to form a foam for application to the fabric.
