Handrail ø42 mm in Bendywood®-beech
bent around a mould with radius 130 cm
at a wood moisture content of 12%
After having taken the handrail from the mould, it was left unsupported (without any fixing).
In this case, the bend had opened up to a radius of 170 cm.
Further opening up to a radius of 250 cm is feasible.
Handrail ø42 mm in Bendywood®-beech
bent around a mould with radius 95 cm
at a wood moisture content of 12%
After having taken the handrail from the mould, it was left unsupported (without any fixing).
In this case, the bend had opened up to a radius of 130 cm.
Further opening up to a radius of 150 cm is feasible.
Handrail ø42 mm in Bendywood®-beech
bent around a mould with radius 50 cm
After having taken the handrail from the mould, it was left unsupported (without any fixing).
In doing so, the following spring-back was noted:
- after 4 days the bend had opened up 5 cm (R = 52,5 cm)
- after 10 days the bend had opened up 12 cm (R = 56 cm)
Semi-circle in Bendywood®-beech
composed of 3 layers of 10 mm each
- Bent and glued around a mould with radius 60 cm.
After having taken the semi-circle from the mould, it was left unsupported (without any fixing).
In doing so, the following spring-back was noted:- after 1 day the bend had opened up 10 cm (R = 65 cm)
- after 10 days the bend had opened up 12 cm (R = 66 cm)
- The same was repeated on a mould with radius 40 cm.
In this case, the following spring-back was noted:
- after 1 day the bend had opened up 5 cm (R = 42,5 cm)
- after 10 days the bend had opened up 8 cm (R = 44 cm)
The tighter the radius is, the less spring-back you’ll get.
The more layers you have, the less spring-back you’ll get.
