<p>A moving rod (1), sliding within a tubular body (2) forced in a hole (14) of a last (13) or sliding directly in a hole (14') made in the last itself (13) has one end fitted with a comb (5) having pointed prongs (4) and the other end having spherical, or rounded ends(7). The pointed prongs (4) protrude from the bottom (15) of the last (13) while the other end is aligned with a pressor piston (8). Two inclined and contrasted devices are mounted on each last, so that the points of the respective prongs (4) protrude from the bottom (15), resulting inclined, contrasted and orientated with one another, towards the toe (27) and towards the heel (28) respectively. When the prongs (4) of the two devices are embedded into the insole surface (16) by the pressor piston (8) it remains adhering and fixed to the bottom (15) of the last (13) thanks to the contrasted orientation of the said prongs.</p> |
