摘要

The machine frame is made up of upper (3) and lower (2) cross-beams connected by side-members (4). The beams have thicker sections (7) which extend over most of their height and slope down into the adjacent sections of the side members. The internal corners of the frame are curved, the curve (6) being tangential to the inner surface of the side-member, but having a smaller radius where it contacts the cross-beam.
