Abstract:
A single motor drive system, for use in connection with stretch film wrapping apparatus for wrapping stretch film around a load disposed at a wrapping station, comprising:a static boom member; a rotational boom assembly rotatably mounted upon said static boom member so as to orbit around the wrapping station of the apparatus at which the load to be wrapped is disposed; a stretch film roll carriage assembly mounted upon said rotational boom assembly so as to be rotatable around the wrapping station along with said rotational boom assembly, and vertically movable with respect to said rotational boom assembly, such that stretch film dispensed from said stretch film roll carriage assembly is able to be wrapped around the load disposed at the wrapping station at different vertical elevational levels; and a single motor drive arrangement operatively connected to said rotational boom assembly and to said stretch film roll carriage assembly mounted upon said rotational boom assembly for controlling both the rotational movements of said rotational boom assembly around the wrapping station, and the vertical movements of said stretch film roll carriage assembly with respect to said rotational boom assembly such that said stretch film roll carriage assembly can be disposed at said different vertical elevational levels with respect to the load disposed at the wrapping station.
