Abstract
The tool has two parallel plates (1) which are joined together and which partially enclose cutting chains (2), at their front vertical edges, driven by a motor (8). The external run of the chain is upwards and the internal run is downwards. At the rear of the tool is a space (3) which receives trench liners (4) which are urged against previously placed liners by an arm (6) projecting from a ram (5). A pair of the tools are typically joined together in a parallel configuration by cross bars and carry horizontal rails which slide on vertical rails attached to the lining machine.
