Device for prodn. of weldable face side edge to corrugated tube

摘要

A holder (13) presses down the edge of the corrugated tube (1) and a shearing tool (11) parallel to the holding-down holder is displaceable parallel to the axis of the corrugated tube. The support (10), the holding-down holder and the shearing tool are wheels rotatable around an axis. The holding-down device or the wheel set contg. it is driven by a motor. The edge of the face side of the support wheel (10) and/or the peripheral surface of the holding-down device is roughened. The device forms a static block in which the corrugated tube (1) rotates. It is fitted on a rotatable head, which rotates around the axis of the corrugated tube. The end of the corrugated tube is supported from the outside and/or from the inside.
