STRAIGHT ON THROUGH

摘要

A good-quality, properly maintained and well-adjusted edge-bander makes it look so easy. Feed a part through one end of the machine and a few seconds later retrieve a banded piece from the other. If it is a single-sided edgebander, and odds are it is, simply turn the workpiece 90 degrees to repeat the process to an adjacent edge or 180 degrees to treat the opposing edge. Between the infeed and the outfeed of even the most basic straight-line edgebander, though, a lot of carefully orchestrated operations take place. First is the feed track system that holds the part firmly in place at the same time it conveys it through the machine at anywhere from 30 feet per minute to three, four or more times faster. After glue is evenly applied to the edge of the substrate, the part travels into a pressure zone, where the edgebanding material is pressed against the glued edge. Next up is flush end trimming of the edgeband, which is immediately followed by top and bottom bevel trimming.
