ABSTRACT OF THE DISCLOSURE Method and machine for making vials from glass tubing, wherein a glass tube with a closed bottom is loaded on a rotatable plate, having a series of holes circumferentially passing therethrough, and is then grasped by upper pliers r provided on a plane not coincident with the rotatable plate, and then grasped by lower pliers also provided on a horizontal plane not coincident with a lower rotatable plate, the tube being continuously rotated on its axis by rotating elements of the pliers and rotated throughout the circumference of the machine by rotation of the suitably controlled rotatable plates. The tube drawn or pulled at suitable intervals by the pliers is during rotation, caused to pass in front of a series of burners, arranged in suitable number on the entire periphery of the machine. These burners are provided with parabolic arc flames. Each of the vial forming tubes also passes in front of a feeling and controlling station measuring and checking the formed rough-shaped piece and in the case causing a further correcting burner to operate. After release from the pliers, the finished vials fall down through holes pro- vided in a base plane into small boxes in the bedplate of the machine.
