A machine for the manufacture and stacking of bags, pouches and the like made from a sheath of a thermoplastic material in which an upper welding jaw and a belt driven horizontal cutting blade are slidably mounted to each other for vertical movement relative to each other and the lower welding jaw is also mounted for moving vertically and has a downstream projecting holding shoulder which has a horizontal transverse counter-blade-groove cooperating with the blade in a jaws lowered and closed position for cutting a portion of the sheath which is flexed between the shoulder and a clamp which presses an advanced segment of the sheath to a stacking table. The stacking table includes a vertically moveable pin carrier for impaling the severed end of a formed bag onto a transverse row of needles. |
