ABSTRACT:
An apparatus for winding a web onto a roll has a pair of support rollers extending along respective substantially parallel horizontal axes and defining an upwardly open cradle holding the roll, a bottom plate extending axially underneath the rollers, and respective axially extending side plates extending upward from the bottom plate and engaging the rollers. The rollers, rolls, bottom plate, and side plates together form an axially extending and laterally closed space. A pair of axially spaced end plates lying in respective upright planes and closing ends of the space are each shaped to fit between the rollers and between the side plates and each can slide axially along the bottom and floor plates between an outer position spaced axially from the rollers and roll and an inner position between the rollers and engaging a respective axial end of the roll. The space between the end plates can be pressurized with air. A drive displaces the end plates between their positions.
