ABSTRACT:
The invention is concerned with a method of opening, axially shirring and dividing off tubular casing material, especially synthetic casing for the sausage manufacture, to form tubular folds or corrugations, and of subsequently conveying the same to a processing location such as, especially, the charging tube of a sausage stuffing machine, with the shirring being performed by pushing forward the tubular casing material against stop means. In accordance with the invention, the said stop means will be put into operation only after the beginning of the advancing movement at a point located in spaced relationship behind the starting end of the tube and is then moved back in accordance with the length increment of the corrugation in the shirring direction. The divided-off tubular corrugations are fed to the processing location by reverting the movement of the stop means in the opposite direction, thereby maintaining an unshirred section permitting an easy closing of the front end of the corrugation for further processing on the stuffing machine.
