发明名称 PROCEDIMENTO PER LA PRODUZIONE DI UN RULLO DI CALANDRA A RIEMPIMENTO
摘要 A method for producing a filled calender roll comprising a load carrying shaft portion and having thereon a cover portion made of paper or cloth or the like. The cover portion is made by subjecting a great number of annular fiber material sheets fitted on the shaft portion to a very strong compression in the axial direction of the roll. The method includes the step of making the sheets oversized in diameter with respect to the diameter of the shaft portion so that there is initially, in the assembling program, a space at the interface of the shaft portion and the cover portion. After the axial compression of the fiber material and under the influence of a vacuum created at the interface, the sheets are caused to fill the void between the cover portion and the shaft portion.
