Abstract
A film roping assembly comprises a roping pulley which is disposed upon the wrapping film dispensing carriage assembly. The roping pulley is vertically reciprocable so as to be movable transversely, across the width of the wrapping film, with respect to the direction in which the wrapping film is being dispensed. The roping pulley is initially disposed at its uppermost position and engages the upper edge portion of the film. As the roping pulley is moved vertically downwardly, the film is condensed or gathered so as to form a roped section of the wrapping film. The process may be repeated throughout a single wrapping operation so as to provide the wrapped film with both roped and non-roped sections.
