Abstract (en)
[origin: EP0498039A1] A re-reeling machine for sheet materials, particularly paper, comprising a series of rollers (9, 10, 11, 13) for feeding the sheet material (20) at constant speed in the space between a group of three rollers (6, 7, 8), into which tubular cores (2) are introduced, around which the sheet material is wound to form reels (20), and in which at least one of the three rollers (6, 7, 8) is foreseen mobile in order to allow the increase in the diameter of the reel during making up and its discharge, the improvements consisting in providing, in addition to the general motorization of the machine which sets in motion the two winding rollers (6, 7), separate motorizations (M1-M4), respectively for setting in rotation the third roller (8), for moving such roller, to vary the centre distance between the rollers (6, 7), and for operating means (16) suitable for introducing the cores (2) into the space between the rollers, all the various motorizations being interlocked with a control unit (C). <IMAGE>
