Abstract

Improvements in the machines for the automatic molding of objects made of plastic or elastomer material, characterized in that a moving support is provided that has a series of fixing means, fixed and mobile, facing each other two by two, and regularly arranged on the support, matrices mounted on the support by means of the said clamping members, plasticizing cylinders fed with plasticizable material, a strip of moldable material detached from the plasticizing cylinders and passing between the open matrices mounted on the support, being the dies capable of closing, in movement period, on the strip of moldable material in order to cut from it patterns that remain in the closed dies during the molding period to be subjected therein to the effects of heat and pressure, the band being cut along one of its edges in order to facilitate its start re the closed matrices, and allow the return of the band, perforated, but not interrupted, to the mass of plasticizable material present in the plasticizing cylinder, the matrices opening after molding and in the process of movement to allow the ejection of the objects molded, further characterized in that matrices of different dimensions are mounted on the support, and a device is provided to automatically regulate the position of the band as each matrix passes in relation to its dimension in a transverse direction to the band, from which it appears that each pair of opposing matrices is presented at the time of closing on the band, so that it cuts near said edge.
