Step for flattening arc-shaped bamboo remaining bamboo outer and inner surface layer, flattening method using the same step and flattening device

摘要: The present invention discloses process and apparatus for flattening arc bamboo sheet. During sheet, radial force is applied while dispersed crack-preventing holes are formed in the yellow layer of sheet includes first heating to soften material, subsequent flattening. one or several pairs axially parallel rolls, each roll pair smooth nailed with lugs surface. has advantages less reduction strength high utilization rate resource no cracking caused by
