Abstract
A device for shearing wooden logs, comprising a beam on which the log is secured and guidedly supported for rotation about an axis, a blade and a pressure bar, and adjusting means for adjustment of the variation of the radius of the curved cutting path and of thickness of the sheared sheets is disclosed.
Claims12
A device for shearing a log longitudinally disposed on a fixed axis of rotation through a curved cutting path having a variable radius of curvature about the fixed axis to produce a thin sheet comprising,
- a beam for supporting and blocking the log to be cut,
- slide means including elongated slides, transversely mounted relative to the fixed axis, slidably supporting and guiding said beam for linear movement relative to the fixed axis,
- means for rotating said slide means and said beam with the log to be cut about the fixed axis,
- cutting means for shearing the log to be cut mounted for rectilinear movement relative to the fixed axis,
- means for shifting said cutting means and said beam with the log to be cut in synchronization with the rotation of said log about the fixed axis, and
- means for adjusting said shifting means to adjust one of the rectilinear motion of said cutting means and the linear motion of said beam with the log to be cut thereby variably adjusting the radius of curvature and thickness of the sheet.
