ABSTRACT:
An apparatus for tensioning an outer layer or web material about a roll of web material includes a tension roller assembly. The tension roller assembly is defined by a rotatable idler roller that is movable into and out of contact with the outer layer of web material by way of a linear drive mechanism. Idler roller contact with the web material outer layer tensions the outer layer about the roll of web material. A tensioner associated with the idler roller adjusts the rotational drag on the idler roller which controls the amount of tension that the idler roller applies to the web material outer layer. A vacuum retraction assembly of the tensioning apparatus acts to further tension the web material outer layer. The vacuum retraction assembly includes a vacuum bar having a plurality of vacuum cups coupled to a vacuum source. The vacuum bar is movable relative to the roll of web material by way of a drive mechanism such that actuation of the vacuum source causes the outer layer of web material to adhere to the vacuum bar while subsequent movement of the vacuum bar away from the roll of web material acts to further tension the outer layer of web material about the roll of web material.
