    摘要: A process for the production of core rolls for the winding of sheet maters, and particularly of photographic base papers, includes a deformable rubber tube which is inserted into a mounting tube and inflated therein through a core casing. The core casing is then slid into the inflated rubber tube and the rubber tube is deflated, and by residual stress the rubber tube exerts a pressure on the exterior surface of the core casing and adheres firmly to it.
