APPARATUS FOR PERFORMING POSITIONAL CORRECTION OF LONG MOLDED MATERIAL, ESPECIALLY, PERFORATED PIPE

摘要

A device is provided for aligning elongated tubes to be cut into tube sections with a saw blade for cutting the tubes, wherein elongated tubes are provided with cutouts spaced from each other at equal intervals and defining raster marks at which tubes are to be cut into tube sections, the aligning device including a plurality of scanning fingers mounted in contact with the elongated tube to be cut into tube sections and spaced from each other along the elongation of the tube a distance substantially smaller than the interval between adjacent cutouts on the tube. A drive device for rotation and axial displacement of each tube is provided. At least one of the scanning fingers is engageable in one of the cutouts upon the rotation and axial displacement of the tube so that the distance between the saw and the cutout can be determined and the tube can be accurately aligned with the saw.
