Background

Bending parts of furniture, such as ribs, gliders and the like, are required, and wood bending is an important process for constructing a sampan. The use of the characteristics of bent wood to make curved shaped members allows for economy of manufacture, material savings and increased strength of the member. Fire-bending wood is achieved by directly heating the wood with fire to soften the wood. Before operation, one end of the wood is fixed, and the wood chips are burned on a bent wood stick and heated. In the heating process, in order to prevent the surface of the wood from coking, water is often added to the baking surface, and simultaneously, the force is gradually applied to gradually bend the wood to the required shape. When bending with applied force, the force is not too large, and the bending is not too rapid, otherwise the wood is broken or cracked. Heating, watering and bending are carried out simultaneously until the wood is bent to the required curvature. In Song Dynasty, people take salix integra sticks, and make box casing, the fire makes the bending soft.
