<p>The invention relates to a method for operating a sheeting machine for laying pipes, and to one such sheeting machine, according to the preamble of patent claims 1 and 7. The aim of the invention is to increase the automation of the laying by means of one such method and machine, and to be able to operate the machine in such a way as to avoid damage thereto. To this end, the advancing forces or the hydraulic pressures required for the advancement of the working cylinders arranged on the cutting sleeve and inside the sheeting are measured and recorded in relation to the mounting position of each working cylinder, and the pressures between the left and right sheeting side are compared. In the event of asymmetry outside a pre-determinable tolerance, the advancing movement of the sheeting machine is automatically stopped or a correction control is automatically carried out.</p> |
