Abstract
The projectile weaving machine is provided with a torsion bar arrangement wherein oil is delivered to a central part of the torsion bar during operation. The oil circuit includes an oil entry in or near the torsion bar mounting and an annular chamber which is defined by a casing part about the torsion bar. A cooler is also provided in the oil circuit for cooling of the oil and the hydraulic brake assembly for the torsion bar is incorporated in the oil circuit.
