Machine for plasticizing with polypropylene by thermal rolling of the type using a sheet of treated polypropylene which is joined to the paper to be plasticized by thermal rolling, which incorporates, at the entry for the paper to be plasticized, a marker for the insertion of the sheets which allows both its manual insertion and insertion with the support of an automatic sheet feeder, always at the precise moment in order to prevent overlap or gaps between sheets. Likewise, it incorporates an oil calender with a hydraulically actuated pressure roller, the assembly being actuated by an electric motor; a wheel for marking the sheet of polypropylene which facilitates its transverse cutting at the desired time, and another for cutting it longitudinally to the dimension of the sheet of paper are arranged in the top part of the machine over the reel of material for plasticization. <IMAGE>
