METHOD OF APPLYING STRETCH FILM WRAPPING TO AN AGRICULTURAL BALE

摘要

A method of applying stretch film wrapping to an agricultural bale using a bale wrapper apparatus which comprises: a bale-supporting table; a dispenser reel arrangement from which stretch film wrapping can be withdrawn to form successive overlapping windings of film which cover the bale; and means for applying relative rotation between the table and the dispenser reel arrangement during a wrapping cycle; in which: each winding (60) of film comprises at least one thin longitudinally extending edge strip portion (61), and an adjoining thicker longitudinally extending portion (62); the thicker portion (62) has a first side (63) adjoining said edge strip portion (61), and an opposed parallel second side (64); and during at least an initial part of the wrapping cycle, each successive overlying winding (60a) laterally overlaps its underlying winding (60) to such an extent that the respective first side (63a) of the thicker portion (62a) of each overlying winding (60a) substantially follows the path of the respective second side (64) of the thicker portion (62) of the underlying winding (60).
