[Problems to be Solved by the Invention] The above-mentioned conventional hand-sewn winding
When winding natural leather around a handle, the two-sided edge of the belt-shaped material is wound around the inside diameter of the handle while folding it to fit the inner circumference of the handle. And it must be folded uniformly over the entire length of both side edges of the strip material, which requires skill. Than before
As is known, natural leather is entangled in fibers and uneven in density depending on where it is collected (from where in the animal's body).
For example, physical properties such as hardness and elongation are not uniform. For this reason, the elongation when pulled with the same tension and the degree of folds when sewn with the same tension also vary, and in order to adjust this well and produce a product, it takes a lot of manual labor Requires skill. For this reason, there is a drawback that the production volume of the skin-wrapped automobile handle is limited and mass production cannot be performed. SUMMARY OF THE INVENTION An object of the present invention is to provide a skin-wrapped automobile handle that can solve such a disadvantage.
