<p>The machine has a sleeve screwing drive (17), which is connected with two parallel vertical pendulum supports in connection with swinging levers of a torsion swing mounted in rotating manner in a machine frame (1), and four pneumatic horizontal supporting cylinders at the machine frame are provided. The torsion swing is rotated over another swinging lever in connection with a pneumatic cylinder against the resistance of two spring mountings between the former swinging levers and the machine frame over a small torsion angle to machine frame. A spring-pressurized compression piece is provided with a spherical cap in each vertical pendulum supports and the spherical cap stands in contact with a ball caster fixed at the sleeve screwing drive.</p> |
