ABSTRACT:
A band saw, especially intended for sawing logs with the grain or dividing wood blocks, comprising upper and lower band pulleys (6,4) which can be adjusted relative to one another. Extending around the pulleys is an endless, band-like saw blade (11) which is driven by one (4) of the bandpulleys. The lower band pulley (4) is journalled in a frame structure (3) which can be moved along two mutually parallel guides (13,14) extending at right angles to the feed direction of the material to be sawn. The frame structure carries a post (5) which in turn carries at the top thereof the other band pulley (6). In accordance with the invention the one guide (14) is located substantially vertically above the other guide (13), suitably so that the two guides (13,14) are located in a common vertical plane which passes vertically through the post (5).
