A pile wire blade holder and blade.

摘要

A pile wire blade holder includes a holding portion 10, arranged to receive and locate a blade20 on the holder, and a wire 12 extending from the holding portion, only a part of which is shown. The holding portion includes a stud 16 which extends through a hole 18 in the blade in order to prevent the blade attempting to move in either direction along the wire when the wire reverses its direction of travel. The blade extends through a milled opening 22 at the end of the holding portion and into the strut 24 running along the wire, with the tip of the blade being wholly located within the slot under a bridge 26. Any tendency for the blade to pivot about the stud relative to the holding portion is prevented or limited by a pair of parallel guides 36 which are accurately located above and below the stud being engaged by the blade.
