Definitions

  • the present invention relates to a hybrid and motorized rubber tapping
  • Rubber tapping is the process by which the rubber sap is gathered by carving an incision in the bark layer along the downward and along the length of the rubber tree.
  • the rubber tapping is skilled work as it need a careful incision longitudinally on bark that helps to open only the latex vessels to get the maximum latex/rubber yield without damaging the tree cambium.
  • a manual tapping knife is generally used to shear off a thin layer of rubber tree's bark. The bark of the rubber tree is cut systematically to the width and depth in a channel shaped position. After the incision is carved in the tree, the latex starts flowing and collected into a container attached to the tree. Few hours after cutting the surface of the bark, a clot is formed in the incision that stops the seeping of the latex. To start the flow of latex a small layer of bark or the clot is required to be removed from the incision. This process is repeated on regular basis to get the maximum Latex from an incision.
