Abstract
A device for producing a drip irrigation tube comprising an extrusion apparatus for extruding a tube body made from a thermoplastic synthetic material is provided. Metering elements are inserted in the extruded tube body and connected to the tube body. A calibrating device adjusts the tube body to the desired outer shape, and a cooling device cools the tube body. Outlet holes are made in the tube body in the vicinity of the metering elements to permit the passage of water from the tube body during use. A control unit for controlling the device for making outlet holes is provided, and a sensor which upon lifting of the roller during passage of a metering element emits a signal to the control unit which emits a signal to the device for making outlet holes.
