Bark or branch stripping machine - has claws, rollers for centering operated by compression cylinders and blades

摘要

The support-frame (1) consists of several semicircular transverse frames (2) interconnected by lengthwise struts (3). Pivot-arms (4) are pivoted on the ends of the crosswise frames (2) which are open on the underneath side. Shafts (6) on the crosswise frames (2) and pivot-arms (4) have pivot-mounted on them centering rollers (7) and/or branch-lopping (8) and paring blades. A hydraulic or pneumatic cylinder operates the machine, levers (12), lever-shafts (13), tension and/or compression rods (14) provide the necessary pressure. The pivot arms (4) are moved by cams (15) fixed to the lever-shafts (16).
