An apparatus (10) for making a post-foaming gel comprising, a first cylinder (12) having a chamber (14) and a slidable piston (16) separating the chamber (14) into a first compartment (18) to receive a gel base and a second compartment (20), and a second cylinder (22) having a chamber (24) and a slidable piston (26) separating the chamber (24) into a first compartment (28) to receive the gel base and a second compartment (30), with the first compartments (18, 28) of the first and second cylinder (12, 22) facing each other. The apparatus (10) has a shaft (34) connecting the pistons (16) of the first and second cylinders (12, 22), and a conduit (38, 40) connecting the first compartments (18, 28) of the first and second cylinders (12, 22). The apparatus (10) has a device (52) for reciprocating the pistons (16, 26) in the first and second cylinders (12, 22) to cycle the base through the conduit (38, 40) between the first compartments (18, 28) of the first and second cylinders (12, 22), and device (42) for introducing a foaming agent to the gel base while it is being cycled between the cylinders (12, 22). |
