ABSTRACT:
The process to manufacture sandals bases on the use of a mold made up by two parts: the first, the lower, containing the upside-down print of that part of the sole which has to be contacted by the foot; the second, that is the cover, containing the upside-down print of that part of the sole which will touch the soil. The upper of the shoe, made up by two straps, have to be inserted, separately, before the molding, in the flutings located on the edges of the lower part of the mold, while the surface which is to form the external part of the upper itself faces upward. At their ends inserted in the mold, these straps are equipped with holes which, during the molding fill with the mix such as polyurethan, or poly vinyl chloride used for the manufacturing of the soles and after its solidification, give a high tear-resistent linkage between each strap itself and the sole.
