A circular saw for re-sawing or ripping wood, timber and the like, such as logs, blocks, cants and boards, into thinner pieces, wherein the saw includes to this end a plurality of saw blades (21, 22) which are mounted on two mutually parallel and vertically spaced saw axles (9, 10), and wherein means are provided for feeding the wood towards those parts of the blades that are located between the axles, such that both sets of blades will saw one and the same piece of wood from opposite sides thereof. The saw axles (9, 10) are each journalled in a respective stand unit (12, 13), wherein the stand units are vertically movable relative to one another so as to be able to saw through wood of large dimensions with the use of pairs of mutually opposing blades (21, 22) for sawing each cut, and wherein the blades are displaceably mounted on respective saw axles (9, 10) so that each blade of the two sets of blades is able to produce its own through-penetrating cut when cutting wood of smaller dimensions. |
