A coreless roll (10, 106) of product that is self-supporting in a rotary dispenser. The roll includes a rolled web of product that is wound throughout its diameter about a winding axis into a cylinder having first and second flat ends (112, 112'). At least one flat end defines a mounting hole at substantially the center of the winding axis of the coreless roll. The mounting hole has a depth and has sides generally perpendicular to the end of the roll. The sides are separated by a distance that is less than the depth of the hole such that the mounting hole is adapted to receive a plunger (200, 200') from a rotary dispenser (202). Methods of making the coreless roll are also described.

Cette invention se rapporte à un rouleau de produit à âme creuse (10, 106) qui peut tenir par lui-même sur un distributeur rotatif. Ce rouleau comprend une bande de produit enroulée, qui encercle sur tout son pourtour un axe d'enroulement, de façon à former un cylindre comportant une première et une seconde extrémité aplaties (112, 112'). Au moins l'une de ces extrémités aplaties forme un trou de montage essentiellement au centre de l'axe d'enroulement du rouleau à âme creuse. Ce trou de montage a une certaine épaisseur et comporte des côtés généralement perpendiculaire à l'extrémité du rouleau. Ces côtés sont séparés par une distance qui est inférieure à la profondeur dudit trou, de sorte que le trou de montage peut recevoir un plongeur (200, 200') provenant d'un distributeur rotatif (202). Des procédés de fabrication de ce rouleau à âme creuse sont également présentés.
