ABSTRACT:
The process is defined by a cyclic succession of identical phases, through each of which the part of the skin subjected to stretching is gradually wound from one extremity to the other, and vice versa, by means of a continuous or discrete surface that exercises an adjustable pressure thereon.
A device with which the process can be carried out is constituted by a netted container, hung from a support, housing spherical objects and banded circumferentially with an elastic. The bottom end of the container is hooked to a wire that defines, in the said end, an adjustable depth lip.
With the said support given a top downward and vice versa movement, the bottom end of the container comes into contact with the vamp and then enshrouds this completely.
Consequently to the motion given to the support, the spherical objects that protrude from the meshes in the net come, first of all, into contact with the skin of the vamp and then roll over and/or rub, under pressure, against the said skin which is gradually stretched.
