Abstract
According to the process of the invention one starts with a block of wood of approximately parallelepipedal shape from which, by means of operations of milling and turning, there are obtained opposed surfaces on which there are subsequently milled parallel channels extending through almost one-half of the thickness of the block. Into the channels there is introduced resilient rubber so as then to obtain a pair of perfectly symmetrical insoles, by making a longitudinal cut along the plane corresponding to one-half the thickness of the block. The insoles being made perfectly resilient by transverse layers of rubber which furthermore have anti-slip properties.
Claims1
A process for producing a flexible anatomical insole of wood for footwear consisting of the steps of:
- Providing a block of wood of approximate parallelepipedal shape,
- shaping said block to obtain two opposed surfaces shaped in the approximate configuration of an insole, with two gripping projections extending from the ends thereof,
- cutting transverse channels on both of said surfaces, wherein said channels extend to approximately one-half the thickness of the block,
- introducing resilient rubber into said channels,
- cutting said block along a plane corresponding to one-half the thickness of the block, whereby two symmetrical insoles are obtained, each comprising transverse wooden strips connected to each other by strips of rubber.
