Abstract:
For tying wire material around a bale, a pair of end portions of the loop is held in a substantially mutually parallel orientation. An engaged section of at least one of the end portions is moved about a longitudinal axis of the other end portion of that pair, such that the pair of end portions is twisted into a wire twist between an engagement area and a portion of the loop extending about the bale. During twisting, wire material of at least one of the end portions slips through the engagement area towards the portion of the loop extending about the bale. An implement and twisters for use in such a method are also described.
