摘要： A mandrel suitable for supporting and unwinding a convolutely wound web material is disclosed. The mandrel has a mandrel shaft with a longitudinal axis, a plurality of mandrel arms extending from the mandrel shaft, and at least one expansion element disposed upon a respective each of the mandrel arms. The mandrel shaft is capable of rotating about the longitudinal axis. Each of the mandrel arms is disposed and rotatable about the longitudinal axis. The at least one expansion element is expandable radially away from the respective mandrel arm relative to the longitudinal axis. The convolutely wound web material is disposable about each of the mandrel arms. Further, the at least one expansion element is expandable into contacting and releasable engagement with the convolutely wound web material. The convolutely wound web material is fixably and releasably disposed about each of the mandrel arms.

摘要： An unwind apparatus for obtaining, loading, splicing, and unwinding convolutely wound rolls of web material and forwarding the web material unwound from each of the convolutely wound rolls uninterruptedly to a downstream apparatus is disclosed. The unwind apparatus provides for a multi-axis robot and an end effector operatively connected to the multi-axis robot. The end effector provides for a stationary motor, a rotational coupling mechanically coupled to the stationary motor, and, a mandrel mechanically coupled to the rotational coupling. The mandrel is capable of releasably engaging the convolutley wound rolls of web material.
