Abstract:

A machine for impregnating a fabric of woven fibers with a viscous liquid. The machine comprises a chamber to contain the medication, first and second slots in opposite sidewalls of the chamber with overlying, first and second, resilient seals carried on the walls of the chamber and bearing fabric-receiving slits. The machine is provided with a supply roll of a continuous band of fabric, e. g. , medical gauze, and a motorized take-up spindle whereby a continuous strip of gauze can be passed through the slits of the seals and the chamber, and be impregnated with the viscous ointment within the chamber. Preferably, the chamber carries a platform plate at the level of the slits and a plurality of apertures are provided in the platform plate. The band of fabric or gauze is directed through the chamber and over the surface of the platform plate so that during its passage through the chamber the viscous material within the chamber will be extruded into the open, porous weave of the fabric or gauze.
