  • Patent number: 5433805
    Abstract: A method for preventing cracks in bamboo canes subjected to drying comprises longitudinally cutting open the bamboo cane along its entire length, allowing the cut cane to dry to a desired residual moisture content, and sealing the resulting longitudinal gap by adhesively bonding into the longitudinal gap a multi-section filler strip. The longitudinal gap may be milled out to produce desired dimensioning and shaping. The strip may also be mechanically attached to the cane by clips, screws or dowels. The cane may be optionally chemically pretreated before drying.
