A tubular core assembly for winding or unwinding sheet material, such as newsprint or Rotogravure Print, wherein the opposed ends of an elongate cylindrical core are provided with inside diameter-reducing annular core insert members. The inside diameter-reducing annular core insert members are secured by a mechanical interlocking member to a central core body formed by multiple wraps of a paperboard material. The mechanical interlocking member includes at least one radially interlocking member secured to and extending radially at least partially through the central core member and the annular core insert member. Because of the mechanical interlocking relationship between the inside diameter-reducing annular core insert members and the central core body member, the inside diameter-reducing annular core insert members are secured to the central core body member in positive locking relationship.
Ensemble de tube conçu pour enrouler ou désenrouler un matériau en feuille, de type papier journal ou imprimé de rotogravure, dans lequel les extrémités opposées d'un tube cylindrique allongé présentent des éléments d'insertion annulaires dans le tube pour en réduire le diamètre interne. On fixe ces éléments avec un dispositif de verrouillage mécanique sur le corps d'un tube central formé de plusieurs couches de carton. Le dispositif de verrouillage mécanique est constitué d'au moins un élément de verrouillage radial fixé au tube central et traversant radialement au moins en partie ce tube central ainsi que l'élément annulaire inséré dans le tube. Parce qu'il existe une relation de verrouillage mécanique entre les éléments annulaires d'insertion dans le tube et le corps du tube central, les éléments d'insertion sont fixés au corps du tube central pour créer un blocage complet.
