A tubular core assembly for a roll of paper or other sheet material has a hollow cylindrical core member of metal or plastic material, the core member having at least one lug projecting radially inwardly from an inner surface thereof adjacent to each end of the core member. Each lug is longitudinally spaced from the respective adjacent end of the core member, and an annular plastic end member is located within each opposite end portion of the core member and is a friction fit therein. Each end member has a notch at its longitudinally inner end receiving the lug adjacent to the respective end of the core member to facilitate transmission of torque and axial chuck pressure from the end members to the core member.
Un ensemble de noyaux tubulaires pour un rouleau de papier ou d'autre matériau en feuilles comprend un élément de noyau cylindrique creux en matériau métallique ou plastique, l'élément de noyau est muni d'au moins un ergot se projetant de manière radiale vers l'intérieur à partir d'une surface intérieure adjacente à chaque extrémité de l'élément de noyau. Chaque ergot est espacé de manière longitudinale à partir de l'extrémité adjacente respective de l'élément de noyau, et un élément d'extrémité en plastique annulaire est situé dans chaque partie d'extrémité opposée de l'élément de noyau et à ajustement serré. Chaque élément d'extrémité est muni d'une encoche à son extrémité intérieure de manière longitudinale recevant l'ergot adjacent à l'extrémité respective de l'élément de noyau afin de faciliter la transmission de couple et la pression de mandrin axiale à partir des éléments d'extrémité vers l'élément de noyau.
