Title:
METHOD AND DEVICE FOR PRODUCING A CASING OF A LARGER LENGTH FOR FOODSTUFFS, PARTICULARLY FOR SAUSAGES
Document Type and Number:
WIPO Patent Application WO2002094024
Kind Code:
A3
Abstract:
The invention relates to a method for producing a casing of a larger length for foodstuffs, particularly for sausages. Said casing is comprised of a number of casing sections, which contain collagens, while using a mandrel onto which a first casing section is slid followed by a second casing section, whereby the facing end areas of both casing sections overlap on the mandrel thus resulting in the formation of an overlapping area of casing sections on which heat and pressure are temporarily applied to at least partially weld the casing sections to one another in the overlapping area. The overlapping area is positioned on a deformable expanding body, which is placed inside the casing sections and whose diameter can be enlarged from an initial diameter up to a final diameter. The expanding body is enlarged from its initial diameter to its final diameter before or during the welding process whereby resulting in enlarging the diameter of the overlapping area as well. The expanding body is permitted to return it its initial diameter upon completion of the welding process.
