A cushioning conversion machine of the type that converts sheet-like stock material into resilient pad-like dunnage product has associated therewith a stock roll holder and loading method characterized by a pair of laterally spaced apart mounts and a stock roll holder having opposite end portions (90, 92) removably supported on the mounts. The stock roll holder includes first and second holder portions each including a spindle member (96) having an axially outer portion forming a respective one of the opposite end portions of the holder, a core insert (98) rotatably supported on and axially carried by the spindle member (96) for telescopic insertion into the hollow core (102) of the stock roll at an adjacent end thereof thereby to support the stock roll for rotation with the core insert, and an axial abutment (130) axially carried on the spindle member (96) axially outwardly of the core insert (98) and projecting radially outwardly beyond the core insert to form an abutment for engaging the adjacent axial end of the stock roll (102) thereby to limit axial outward movement of the stock roll (102) relative to the spindle member (96).

Machine de transformation du type transformant une matière première en feuille en un produit de rembourrage souple, qui comporte un support de rouleau de papier, et procédé de chargement caractérisé par une paire de dispositifs de montage latéralement espacés, ainsi que support de rouleau de papier doté de parties terminales (90, 92) opposées soutenues amovibles par les dispositifs de montage. Ledit support de rouleau de papier comprend des première et seconde parties comprenant chacune une tige (96) dotée d'une partie axiale externe formant respectivement l'une des parties terminales opposées du support, une partie centrale d'insertion (98) soutenue rotative et axialement par la tige (96) en vue de son introduction télescopique dans la partie centrale creuse (102) du rouleau de papier à une extrémité adjacente dudit rouleau, supportant ainsi le rouleau de papier en vue de la rotation avec la partie centrale d'insertion, et une butée axiale (130) portée par la tige (96) axialement vers l'extérieur de la partie centrale d'insertion (98) et faisant saillie radialement vers l'extérieur au-delà de ladite partie centrale d'insertion pour former une butée destinée à se trouver en contact avec l'extrémité axiale adjacente du rouleau de papier (102), ce qui limite le mouvement axial vers l'extérieur du rouleau de papier (102) par rapport à la tige (96).
