Window frame mfg line - additional frame tipping operations are avoided by moving the frame to a weld dressing machine in a near vertical on end position

摘要

A process for mfg. frames from plastic or metal profiles involves welding the frames at the corners and dressing the welded corners one after the other in a machine which rotates the corners into a suitable position for dressing. In the described process additional frame tipping steps are avoided by the frame being welded together in the vertical position and then moved to the dressing machine in the on end position. The frame with one corner at the bottom is dressed and then rotated several times to allow the operation to be performed on each corner. USE/ADVANTAGE - For welding and dressing the corners of frames, particularly window frames, produced from extruded profiles. Additional frame tipping steps used in previous equipment are eliminated.
