Abstract

The invention relates to a method for closing the end of shirred tubular casings which comprises deshirring a terminal portion of the tubular casing in the direction of the axis of the stick, turning over the deshirred terminal portion in order to insert same inside the casing, securing the deshirred terminal portion from inside the casing, rotating the terminal portion and flattening the rotated terminal portion. This method is performed at the outlet of the shirring line (ON-LINE) as an additional phase of said operation, or it is performed away from the deshirring line (OFF-LINE) as an operation independent from the deshirring.
