METHOD AND APPARATUS FOR MAKING TELESCOPIC PROPS
A method and apparatus (1) for making telescopic props (2), which comprises the steps of: feeding a first tubular body (3) preformed along a feed line (L); said tubular body (3) having a series of through holes (7) formed along the same longitudinal extension line of the tubular body (3); and making a series of incisions (5) at said through holes (7), each incision being representative of a measurement information of said prop (2).
