Abstract:
A piece insertion method for a pipe, for example an irrigation pipe, including: ejecting at least one piece, for example a dripper, from an ejection unit, advancing the at least one dripper inside the irrigation pipe by a dripper advancing unit, lifting the dripper towards the inner surface of the irrigation pipe by using a lifting device such that the dripper is parallel or substantially parallel to this inner surface of the irrigation pipe on impact with this inner surface. The method according to the invention allows also coordination between the lifting device, the ejection unit and the dripper advancing unit such that the dripper spacing can be maintained in tight tolerances.

Abstract:
A dripper detection device for an irrigation pipe manufacturing system includes a continuous pipe feeder capable of making a pipe equipped with drippers, each dripper having a water outlet. The pipe circulates along a predetermined circulation direction (X-X′) while keeping the drippers' water outlets in a predetermined orientation. The dripper detection device includes a laser detection unit with a laser source emitting a laser beam directed to the pipe outer face location where drippers are present at regular intervals, and a laser signal receiver which receives and analyses the laser beam reflected on the pipe outer face to provide a transformed reflected signal which contains information about the passage of each dripper facing said laser detection unit.

Abstract:
A pipe drilling device for an irrigation pipe manufacturing system including a continuous pipe feeder capable of making a pipe equipped with drippers, each dripper having a water outlet. The pipe circulates along a predetermined circulation direction (X-X′) while keeping the drippers' water outlets in a predetermined dripper orientation (Z-Z′). The pipe drilling device includes a rotary drilling unit which rotates around an axis of rotation (Y-Y′) which is orthogonal to the circulation direction (X-X′) and to the dripper orientation (Z-Z′). The rotary drilling unit is equipped with at least one drilling tool and is distant from the pipe so that said drilling tool is able to drill a hole in the pipe wall at a location of a dripper when the angular position of the drilling tool corresponds to the closest position from the pipe.
Abstract:
A device for controlling the transfer operation of wire from one spool to the next in an automatic double coil-winder provided with a traverse winding mechanism which moves alternately in a back-and-forth motion along the entire width of the spools, starting from one of their ends where wire-catching means are located. It comprises a counter capable of continuously counting the length of paid-out wire, means for doubling the counter''s counting rate and for stopping the counter from functioning during the back travel of the traverse winding mechanism, a control element actuated by the counter when the predetermined length of wire has been counted which causes a reversal of the sense of travel of the traverse winding mechanism, and means for initiating the transfer operation which is actuated when the traverse winding mechanism reaches the end of its back travel following that final reversal of its direction of motion.
Abstract:
A double bobbin coil winder having one bobbin in fixed position and another movable along its own axis from a winding position with its flanges parallel and aligned with the flanges of the fixed position bobbin to an unloading position axially offset from the winding position.
