This unedited video shows how
This unedited video shows how a pre-finished, solid wood edgeband is applied to a laminate panel with the MOBIL 2500 edgebanding press by Hoffmann Machine Company. The glue used is standard yellow PVA glue, no special catalysts or hotmelt adhesives are needed!
The wooden edgeband profiles are warmed in the pre-heater bar mounted above the machine. After a few minutes of warming up, the wood strip is placed "warm side up" on the main heating bar and glue is applied to the panel's edge.
An adjustable miter stop is used to accurately position the panel's square edge with the inside corner of the edgeband' s miter. The reference bolt is adjusted to compensate for different edgeband thicknesses. This feature is a huge time saver and solves the alignment problems (e.g. sliding moulding) common when using bar clamps to apply mitered edges. With the bolt removed, the stop is used to align square-cut edges profiles as well.
The machine is operated with two pneumatic valves per station; one valve operates the horizontal cylinders pressing the panel against the back support plates. Once clamped in place, the second valve is actuated to pull the clamped panel straight down onto the edgeband.
The horizontal main heating bar warms the outside or face-side of the edge profile during the pressing process, relieving any stress induced by the pre-heating process.
Both heating elements have individual thermostats and the main heating bar is set to a lower temperature when prefinished moulding is applied (to avoid damage to the finish).
The round panel support discs can be adjusted to locate a finished edgeband profile flush with the panel surface (as shown in the video); when using an unfinished edgeband the supports are set to center panel on the edgeband and the protruding edges on both sides are later planed flush with a Hoffmann BH-556 Edge Lipping Planer.
The cycle time shown in the video is the actual time it takes to apply one edge of solid wood, prefinished edge moulding. The heated wood quickly draws the water out of the yellow glue, resulting in a strong, reliable glue bond in only minutes.
The MOBIL 2500 edgebanding press has a working length of 8 feet and features two clamping stations with two cylinders each while the MOBIL 3000 has a working length of 10 feet and features three clamping stations with two cylinders each.
