Gathering member for sausage casings - with helical projection of hard plastic with good gripping characteristics

摘要

Gathering member for a device for gathering tubular plastic sheets, partic. sausage casings, comprises a hollow body with a concentric bore with a helical rib of a plastic material of such hardness and gripping characteristics that the casing is gathered when the member is turned at high speed. Pref. curable or thermoplastics are used, partic. polyurethane, polyacrylate, polyester, polyamine, polyolefin, silicon, EPM, EPDM, or natural or synthetic rubber. ADVANTAGE - Risk of damage to the casing is small.
