TH721C3 - The bending process, the stick handle made of bamboo. - Google Patents

Abstract

Walking stick according to this invention There are 4 steps to the fabrication process: 1. Flexibility in wood by means of heat treatment 2. Bending 3. Tensioning and drying 4. Decoration and improvement The bending process is an important step because Requires both science and art together as well

Claims (1)

1. The process of bending the cane handle made of bamboo. Which has the following steps Build flexibility in wood Starting from selecting raw bamboo. With diameter The center of the trunk is about 2.5-3.5 centimeters, which is suitable for use by a newly cut bamboo. The wood is not dry. This may be used as soon as it has been cut or if cut and left in the shade should not be longer than 5 days, because if it is longer than that, there will be insufficient moisture in the wood. (The handle) to burn with the fire from cooking gas. At a temperature of about 200-500 degrees Celsius for about 2-5 minutes when the wood has been The heat is flexible in its body, making it easy to modify shape. If bamboo has been Overheating can be easily broken. So we need to pour water to reduce the heat level down to suit (temperature not higher than 80-100 degrees Celsius), bending, making shape. When the bamboo has received proper heat (80-100 degrees Celsius), it is placed alternately with the pillar on the bending platform to bend. Then give out Flexural force by manual force or a machine to bend the bamboo into the desired shape, the bending needs to be repeated several times because it can bend little by little, that is, will The bamboo has to be burned and bent several times until the bamboo has the desired shape. Fixing and drying When the desired shape has been bent, a wire or rope is tied at the end. Pinch the bent part to the body The cane until the handle of the cane is dry and the hardwood retains the desired shape because the bamboo has not dried and has not hardened. It is able to change the contours in any direction, so fixing the tip and body together is to maintain the shape. Or maintain the desired shape after the bamboo has dried and the wood has hardened Which way to do Let the wood dry and hard. By applying to the sun with a heat temperature of about 40-45 degrees Celsius a day for 8 hours continuously for 4-6 days Or put into the oven at The temperature is 70-85 degrees Celsius for 3-4 hours, then take it out of the oven and let the temperature reduce for 1-2 hours and put it in the oven for 3-4 hours. Complete bending
