Edgebander Straight, Feedthrough

Edgebanders are used to apply edging to panel products. Most machines will trim the edgebanding to length and flush with the panelâ&#x20AC;&#x2122;s surface. More sophisticated machines allow profiling of edges and ends, as well as the capability to apply laminate and solid stock to panel cores.
