ABSTRACT:
The tubular body is laid in a horizontal position on a tapered suction drum and pivoted thereby into a vertical axis which is in coaxial relationship with the axis of a mandrel with a punch. The tubular body is then pushed from the surface of the suction drum on to the mandrel by a thrust member. The mandrel and/or the die is mounted displaceably in a vertical direction, which permits particularly stable and precise guidance. A plurality of dies with mandrels and punches associated therewith is disposed on a rotary member. In the course of a revolution of the rotary member, the tubular body on the mandrel is connected to a squeeze moulding in the die.
