Description

3 4

According to the required length of the artificial casing (produced in mixed polymerisation and then generally between 10 and 50 m), a heat stabilizer is added to the casing at the end; The one notch 7 at the end of the mandrel 3 with a mixture was tied off with a conventional inflation cord 11 and the intestine behind it was severed to produce a hose-shaped artificial separation. Compression of the pleated bowel to a film thickness of 0.03 mm and a penetration generally ¹ Z ₂₀ to V _{60 of} the stretched length. subject to knife of 80 mm.
Subsequently, the mandrel 3 together with the after insertion of a tubular dome made of pleated intestine on the screwed part 8 of corrosion-resistant steel with an outside penetration and immersed in a container 10, the knife of 30 mm in the intestine became a mechanical solution 9 of water-soluble High-polymer crinkling operation according to FIG. 2, to fix the wrinkles (Fig. 3) that adheres to the skin until the intestine is about Vs its original length. As in Fig. 4 is shown which was compressed. The intestines are then dried in a drying room on the crinkled surface of the intestine. was is preferably about 6 ° / _o sodium polyvinyl alcohol was sprayed with an atomizer, an aqueous solution of the drying temperature.
