Abstract
A wrapping apparatus applies a wrapping medium to an annular article such as a coil of a metal strip, to cover the inner surface as well as the outer surfaces thereof. The apparatus includes a rigid loop structure defining an endless T-sectioned track, and extends as a cantilever extending from a free standing columnar support. The support includes an elevator device for raising and lowering the loop structure. The loop structure includes a hinged gate portion that may be moved to an open position to enable the track to be linked with the annular article, and then reclosed. A self-propelled shuttle moves around the track and carries a dispensing device and a prestretching device that hold wrapping medium and enable the medium to be removed from the coil. A trolley with two power driven rollers continuously reorients the article as wrapping proceeds. A take-up accumulator device is disposed on the shuttle, and includes a plurality of fixedly positioned training rollers, a plurality of yieldably positioned training rollers, and a pneumatic loading device which resiliently loads the yieldably positioned rollers away from the fixedly positioned rollers, so as to maintain tension in the wrapping media.
