Abstract

The tool is used for tying together concrete reinforcement rods using wire twisted around the junction. The tool body is a cylindrical tube contg a hollow shaft. This has double helical grooves, the pitch increasing progressively to the front. At the front end is a bearing (8) and a cap (2, 9) contg ball bearings running in the grooves. A fixed and a spring loaded mobile jaw on the shaft apply the wire, passing axially up the shaft. A pumping action provides the twist, the balls driving in one direction only under spring (6) assistance.
