Bamboo slabs are offered, but the products are bamboo skin,
It is of the remaining inner part where the endothelium and outer skin have been removed. In the manufacturing method, the remaining contents of the bamboo skin, inner skin and outer skin are shaved and flattened while being heated by high frequency heating or the like. However, since the bamboo slabs produced in this way are only internal, the appearance of natural bamboo is difficult to perceive, the taste is insufficient, the surface hardness is low and the mechanical strength is low. There was a problem such as small.

After splitting a long fresh bamboo with two knots vertically into half or more to make a long fresh fresh bamboo, the inner skin and the inside of the same long fresh fresh bamboo are scraped off. To leave the long, vertically split fresh bamboo skin, and then pressurize both sides of the fresh bamboo skin by applying high-temperature steam to the long fresh bamboo skin and applying heat to the fresh bamboo skin. By developing the curved surface to a flat surface and then cooling, a long bamboo skin flat plate having at least one raised node on the surface is manufactured. In the above method, the step of vertically dividing a long fresh bamboo having at least one knot portion into half or more vertically into a long vertically fresh bamboo is performed by wedge-cutting a conventional blade. 1 by the vertical split method
/ 2 or more. In addition, the step of shaving the inner skin and the inside of the same long vertically split fresh bamboo can be performed by, for example, a known method described in Japanese Patent Application Laid-Open No. 4-67902, “Method and Apparatus for Producing a Long Bamboo Plate”, and Japanese Patent Application Laid-Open No. 7-108505, Bamboo cutting method and apparatus ", and JP-A-7-108506," Bamboo material thickness determining method and apparatus ".

することによって実施できる。The long vertically split fresh bamboo skin obtained in this way is heated on the front and back surfaces of the long fresh bamboo skin while heating it by applying high-temperature steam to the long fresh bamboo skin on the transporting path in the longitudinal direction. In the process of expanding the curved surface of the fresh bamboo skin to a plane,
It is preferably performed on a transport path composed of a number of upper and lower rollers, for example, by an apparatus and a method as described in Japanese Patent Application Laid-Open No. 7-108507, entitled "Heating Device for Curved Plate and Expanding Device and Method". However, in this case, particularly in the production according to the present invention, the multiple upper rollers are each independently suspended so as to be able to move up and down elastically.
As a result, even if there is a raised node on the surface of the long vertically split fresh bamboo skin, each roller elastically follows up and down, and the node can be crushed and deformed or destroyed. It will be avoided. In the method, instead of heating the long fresh bamboo skin by applying high-temperature steam, for example, superheated steam, the long fresh bamboo skin can be heated by applying hot water to the long fresh bamboo skin, or high-temperature steam can be heated. It is also preferable to heat with a combination of water and hot water. The heating temperature is preferably around 130 ° C. Next, the flat bamboo skin flat plate that has been developed as described above and still retains a high temperature is cooled by radiation of cold water and compressed cold air to be a finished product. In addition, it is also preferable to apply a colorant such as blue, brown, red, and black to various desired colors, for example, to a long bamboo skin flat plate, and to apply a color by immersion, and to apply the colorant in a step before the cooling step. -It can be carried out by immersing, or by applying and immersing a colorant to the cooled one.

できる。3. Development process of long vertical fresh bamboo skin. (1) 2. The long vertical split bamboo shell having a curved surface after the autoclave treatment obtained in the step is spread to a flat plate on a transport path of a developing device (a flat bamboo skin flat plate manufacturing device) shown in FIG. That is, the curved surface of the long vertically split fresh bamboo outer skin 1 is developed by the upper and lower roller groups 3 and 2 which pressurize the front and back surfaces to develop and transport the curved surface to a flat surface. The unfolding / transporting speed is about 4 m / 1 min, but the unfolding time of the long bamboo skin of 5 m in length is about 1 minute in consideration of the insertion work time and the like. (2) A number of superheated steam nozzles 6a and 6b are arranged above and below the roll groups 3 and 2 in the developing device, and superheated steam (high-temperature steam) is jetted from each nozzle toward the center.
Upper and lower rollers 3 1 to 3 9, 2 1 performs softening due to water supply and heating to 2 9 to the heating and long bamboo outer skin member 1, ease of deployment, to enable increase in the development speed. Since the deploying device is covered by the cover housing 7, the inside of the deploying device is filled with superheated steam and heat. Further, a bath 8 is provided at the bottom of the deploying device, and receives and stores warm water generated by liquefaction of superheated steam. (3) upper rollers in the deployment device, the lower roller is as above described and the rollers 3 1 to 3 9 of the upper rollers 3 is resiliently movable up and down by the elastic support 4 ing. As described above, in particular, since each upper roller is elastically supported by the elastic support so as to be able to move up and down, even if there are knots raised from the surface of the long vertically split bamboo skin, the portions are extremely pressed. It unfolds flat without cracking and deformation. (4) The cooling device (for example, 4 m in length, not shown) is a tunnel type equipped with a transport roller, is disposed behind the developing device, and is an injection device similar to the high-temperature steam injection method in the developing device. As a result, cold water is jetted, and air is jetted at the same time. This increases the cooling rate. The length of the cooling device can be 4 m, 8 m or 12 m as required.
