Winding machine

In a roll-winding apparatus for winding sheet material into a plurality of wound rolls comprising;

• a winding drum rotationally driven at a constant speed of rotation;
• feed means for advancing a travelling sheet material longitudinally in contact with a peripheral sector of said winding drum;
• means for automatically presenting elongated cores individually and successively to a winding station at said sector and in contact with said travelling sheet material and pressed thereagainst and against said drum in position parallel with said drum for each being rotationally driven about a corresponding longitudinal axis thereof;
• said means for automatically presenting elongated cores comprising means biasing the individual cores in a direction toward the periphery of said winding drum;
• means for winding a leading end section of said sheet material on each successive rotating core at said winding station and each with a desired length of sheet material wound thereon as a wound roll;
• said means for presenting said elongated cores to said winding drum comprising means to transfer successively would rolls from said winding station to a discharge station on said drum downstream of the winding station while maintaining sheet material wound on each of said wound rolls bearing against said winding drum for rotating by said drum about said corresponding longitudinal axis of each corresponding core;
• said means to transfer comprising means driven intermittently angularly equal increments about the longitudinal axis of said winding drum;
• means to automatically sever the sheet material during each transfer of a wound roll from said winding station;
• and said means for winding said leading section comprising means for automatically winding on each said successive core a leading end section of each next successive length of sheet material after severing of each length of sheet material from said sheet material upon winding thereof on a corresponding core.
