Abstract
A method of, and apparatus for, flexibilizing or softening leather or like materials wherein opposite marginal regions or lines of at least one area section of the piece of material to be worked and extending at least partially over such piece of material are moved periodically in relation to each other. This relative movement comprises or consists of a movement component directed parallel to the plane of said piece of material. This can be achieved by means of at least two tools moved appropriately in relation to each other and acting on the material by imposing an alternating deformation thereon comprising a movement component parallel to the plane of the piece of material.
