Abstract
Abstract The mold according to the invention is in two opening parts. Its first part defining the lower sole face and presenting spiked holes, delimits receiving recesses shaped to complement the molded heads of the spikes and adapted to receive the corresponding heads while ensuring a perfect contact capable of preventing any of the molding material from filtering in, whereas the second part of the mold, defining the upper sole face and provided with bosses projecting opposite the said holes, comprises push-rods on the bosses conjugated with the recesses, to hold the corresponding heads in position inside the latter when the mold is closed.
