Abstract:
Portable apparatus adapted to be moved along a circular locus around an article disposed at a wrapping station so as to be capable of wrapping the article in wrapping film, comprising:a manually movable portable push-cart; a vertical mast member mounted upon said portable push-cart and having a plurality of vertically spaced apertures defined therein; a film roll carriage vertically movable upon said vertical mast member; a roll of wrapping film mounted upon said film roll carriage; and a dual-stop pin mechanism operatively mounted upon said film roll carriage and comprising a pair of stop pins which are operatively connected together so as to be alternatively movable between first extended and second retracted positions such that when a first one of said pair of stop pins is moved toward said first extended position so as to be operatively engaged with one of said plurality of vertically spaced apertures defined within said mast member in order to lockingly retain said film roll carriage at a particular elevational position with respect to said vertical mast member, a second one of said pair of stop pins is moved toward said second retracted position so as to be operatively disengaged from said plurality of vertically spaced apertures defined within said mast member, and alternatively, when said first one of said pair of stop pins is moved toward said second retracted position so as to be operatively disengaged from said plurality of vertically spaced apertures defined within said mast member, said second one of said pair of stop pins is moved toward said first extended position so as to be operatively engaged with one of said plurality of vertically spaced apertures defined within said mast member so as to lockingly retain said film roll carriage at a particular elevational position with respect to said vertical mast member, whereby said film roll carriage can be safely moved along said vertical mast member in an incremental manner.
