摘要： .A method for the manufacture of helically wound pipes, wherein the pipe is manufactured in that a steel strip (9) is passed to a forming unit (2) for profiling the steel trip and is passed from the forming unit to a winding unit (3) where the profiled steel strips sre wound to a pipe, the force by which the forming unit pushes the strip forward to the winding unit is measured by means of a weighing cell (12, 15). The length of the steel strip between the forming unit (2) and the winding unit (3) is kept constant by means of a partly open channel in which the steel strip extends. Weighing cells (12) are fixed along part of the channel, measure the force applied by which the forming unit pushes the strip forwardly. Furthermore, the weighing cell may send a signal, which is used for controlling the forming unit so as to keep the pushing force constant.
