Whilst taking into account the specification of the machine, to achieve an optimum seam appearance there must be an adequate number of pressure rollers, which are adjusted to the correct setting.

End trimming

The end trim cut is performed using standard set saw blades with pointed teeth. Saw blades with alternate tooth sets are only of limited use as they can cause splintering, particularly when working with thin edge banding.

Milling

Four- to six-blade cutters with a diameter of approx. 2.75 inch (70 mm) and a rotational speed of between 12,000 and 18,000 rpm should be used. The exact choice depends on the characteristics of the cutter and the machine. Blunt tools running at incorrect speeds can damage the edge banding. If any smears should occur, the speed of the milling cutter should be reduced or the feed rate increased as necessary. To facilitate waste
