Section 008: Clamping & Laminating

Edgebander Straight, Feedthrough

Edgebanders are used to apply edging to panel products. Most machines will trim the edgebanding to length and flush with the panel’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.
