<p>PURPOSE:To simplify a presser piece removing device and to eliminate trouble such as derailing of drawing rope during drawing work by additionally providing a swing metal having one end pivoted to the presser piece and the other end provided with a pulley. CONSTITUTION:A swing metal 6 has one end pivoted to a shaft 2a at the end of one presser piece 2 and the other end formed with a clevis for bearing a pulley 7. A drawing rope D is stopped, at one end thereof, to the central part of a tail metal 3 through a pin 3a. Upon finish of connecting work of split wire, a semi-wire S2 is loosened to transfer tension to a wire. Consequently, wire gripping force of cam lever 4 is weakened. The drawing rope D is then drawn on the ground. At that time, the swing metal 6 simply responds slightly to the direction of a worker even when he stands on the side of the wire, and the direction of drawing force matches with a line connecting between the shaft 2a and the pin 3a. Consequently, the presser piece 2 can be removed easily. Upon removal of the presser piece 2, wire W gripping force disappear completely and a come along falls naturally along the wire onto the ground.</p> |
