Method & apparatus for producing pipes for drip irrigation |
摘要 |
A technique for manufacturing extruded drip irrigation lines including drip irrigation elements having a non-circular cross section including the steps of: extruding a drip irrigation conduit; and heat welding discrete drip irrigation elements having a non-circular cross section to a portion of the interior surface of the drip irrigation conduit extending over less than the entire circumference thereof, the step of heat welding including the following steps: sequentially feeding discrete drip irrigation elements through the interior of the drip irrigation conduit; causing individual drip irrigation elements to establish initial contact with the extruded conduit as the extruded conduit is being stretched to its final cross sectional dimensions; and completing heat welding of the elements to the conduit when the conduit has substantially reached its final cross sectional dimensions. <IMAGE> |
