FORMING ROLLER OR SUPPORT ROLLER FOR PACKING TAPE USED ON LIQUID FILLED VESSELS

摘要

FIELD: packing. SUBSTANCE: forming roller or support roller for packing tape is included into set of rollers with outer peripheral surface curved in direction of axis of rotation. Roller set is arranged in places of forming flat tape into tube or in places of support of packing material after its forming into tube. Each roller is divided into many parts by planes square to axis of its rotation. Packing material tape is passed between rollers of set and packing material surface comes into contact with outer peripheral surface of indicated roller set. Each separate part of rollers rotates independently when packing material tape is moved between rollers. Part of roller of smaller diameter rotates more quickly than part of roller with larger diameter, but there is no considerable difference in peripheral speeds of outer peripheral surfaces of rollers. Thanks to it resistance of rollers relative to packing material tape is reduced and tape is passed more smoothly. EFFECT: reduced resistance of rollers.
