摘要： A method of forming holes in plastic tubes which includes advancing a rotating shaft into and through the wall of the tube while maintaining a rate of rotation sufficient to cause the material of the tube to be distressed sufficiently to fluidize and/or disintegrate from the area of operation of the shaft, moving the shaft from the hole, and allowing the periphery of the hole to solidify.

摘要： A drip irrigation conduit comprising first and second elongated tubes. The tubes have an outer wall of sheet material defining the outer periphery of the tubes. A common wall of sheet material extends from one region of the outer wall to another region of the outer wall to separate the interiors of the tubes. A portion of the common wall overlaps a portion of the outer wall, and these overlapping portions have confronting surfaces. At least regions of the confronting surfaces are spaced apart to define a transfer passage leading from the first tube to the second tube. Discharge orifices lead from the second tube to the exterior of the outer wall.
摘要翻译：一种包括第一和第二细长管的滴灌导管。管具有限定管的外周的片材外壁。片材的公共壁从外壁的一个区域延伸到外壁的另一区域以分离管的内部。公共壁的一部分与外壁的一部分重叠，并且这些重叠部分具有相对的表面。相对表面的至少区域间隔开以限定从第一管引导到第二管的传送通道。排放孔从第二管导出到外壁的外部。
