Abstract

Device for perforating thin walled corrugated tubes particularly of thermoplastics having a punch holder which rotates in the axial plane of the guide for the corrugated tube, the punches penetrating the tube walls perpendicularly. The punches are mounted radially on a rotating holder and operated by springs against stops. They preferably have the curved profile of the tube on their cutting edges. A magnetic core with orifices for the punches is placed within the tube. By enabling holes to be punched either at the crest or trough of the corrugations the device economically treats tube for land drainage and other uses.
