CURVES OF GLUED BENDYWOOD® LAYERS can be made using thicker lamellas in contrast to those consisting of glued layers of normal wood: this improves the quality and simplifies the production process. Bendywood®-lamellas are available from 2 mm thickness onwards, in widths up to 300 mm and in lengths up to 6.000 mm.
By gluing several layers of Bendywood® in a mould, it is possible to:
- glue without counter-mould, as the Bendywood® can be bent to shape onto a simple mould using clamps and small blocks of wood. Furthermore it is also sufficient to sand only the layers’ visible surface, before bending and gluing them! Examples to this you can find on our website under the rubric "Photos glue-laminated bending parts".
- obtain clean, hardly visible glued joints if the individual layers are only bent to a radius of 1 : 20 (i.e. a 3 mm thick lamella, for instance, bent to a radius not tighter than about 6 cm). In case layers are cut from the same wooden block of Bendywood®, curves uniform in colour and grain can be produced, identical to bent parts in solid wood.
- obtain dimensionally stable bent parts, because the glue stabilizes the bent parts. Use glues with a long open time!
But also bent parts consisting of glued layers are subject to a certain degree of "rebound" when taken off the mould. Also in this case the parts need to be bent to a tighter radius than the final requested one in order to compensate for the opening. For example, 5 layers with 3 mm thickness bent and glued onto a 90° angle with radius 60 mm should be bent and glued onto a 88° mould, in order to obtain a bent part with an angle that remains stable at 90°.
