Abstract

An instantaneously controlled feeding calender in welding machines for plastic materials, comprising an upper feeding cylinder (12) and a lower feeding cylinder (13) superimposed on each other and mounted on parallel axles, between which a plastic or thermoplastic film (14) is fed so as to form a bag or similar, a welding group downstream of the cylinders (12, 13) comprising an upper welding arm (15) and a lower welding arm (16), and a collecting area (18, 20, 21, 22) for finished bags (19), where each cylinder (12, 13) is equipped with an independent motor (27, 28).
