Abstract: This invention relates to an improvement in a process for producing fibrous (reinforced) artificial sausage casings. In the basic process, a porous web is formed into a tube, impregnated with polymeric dope in an impregnation zone vented for removal of accumulated fluids, coagulated, regenerated, and then inflated for drying. The improvement in this basic process resides in the method for venting fluids from the tubular fibrous casing and comprises masking a section of the porous web with a masking agent prior to impregnating said web in said impregnation zone thereby preventing this section from being impregnated with the polymeric dope and then removing said mask after the casing has passed through said impregnating zone. In a preferred embodiment after regeneration and prior to drying, the masked section is coated with a flexible, air impermeable film-forming material.
