Abstract: A rewinding machine winds a web material into a log about a core. The web material to be wound is directed about a rotating winding drum. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the core is inserted and through which the web material is directed. A surface of the continuous loop opposite the winding drum across the nip is configured to move in a direction generally opposite of the winding drum for winding the web material about the core. A rider roll defines a winding space with the winding drum and the continuous loop. The rider roll is movable relative to the continuous loop and the winding drum to allow for an increase in a diameter of the log in the winding space during winding of the web material about the core.

Abstract: In a web winding apparatus for winding a web on a winding core, the winding core is rotated by a predetermined amount while an end portion of the web, which is held by a holding mechanism, is pressed against the winding core. Thereafter, the holding by the holding mechanism is released, and thereby the end portion of the web is attached to the winding core. Thereafter, the winding core is rotated, and the web is wound up on the winding core. A rotation speed of the winding core when the web is being pressed against the winding core is a higher speed than a rotation speed of the winding core at the time of attaching the web to the winding core. In this manner, the web is accurately wound on the winding core.

Abstract: Coreless tissue rolls can be produced without having to use an adhesive to form a hollow center. Instead, moisture can be used to promote light hydrogen bonding between the layers of the tissue web that line the hollow center. The hydrogen bonding provides sufficient structure to maintain the shape of the hollow center without rendering the tissue web surrounding the passageway unusable. Passageways can also be formed in accordance with the present disclosure that are substantially circular so that the rolls will easily spin on a spindle. In an alternative embodiment, moisture is not used in constructing the wound tissue roll.
