发明名称 METHOD AND DEVICE FOR THE PRODUCTION OF ROLLS OF WEB MATERIAL WITHOUT A WINDING CORE
摘要 A surface rewinding machine for the production of rolls of wound web material is described. The machine comprises: a winding cradle (1, 3, 5) for winding the web material and sequentially forming rolls (R) of wound web material; an insertion device (25) for inserting sequentially, into said winding cradle, winding spindles (M1; M) on which the rolls are formed; an insertion path for the spindles inside the winding cradle. A suction system (51) which follows the spindles along at least one portion of the insertion path so as to produce a vacuum inside the spindles is also envisaged.
