Abstract
A pair of saw blades comprises a first blade (1), which is adapted to rotate in a first direction about an axis of rotation (r), and a second blade (2), which is adapted to rotate in a second direction opposite to said first direction about the same axis of rotation (r), wherein each blade (1, 2) has a blade body (3, 4) and cutting elements (5, 6), which are provided along the periphery of the blade body (3, 4) and adapted to run close and in parallel to each other when the blades (1, 2) are rotating. A spacer means (7), which extends into a space between the two blades (1, 2), is attached to at least the blade body (4) of one of the blades (2) in order to support itself against and slide along a peripheral part of the other opposite blade (1).

A pair of saw blades, comprising:
- a first blade, adapted to rotate in a first direction about an axis of rotation;
- a second blade, adapted to rotate in a second direction opposite to said first direction about the same axis of rotation, wherein each blade has a blade body and cutting elements, arranged along the periphery of the blade body and adapted to run close and in parallel to each other when the blades are rotating;
- and
- a spacer, extending into a space between the two blades and attached to at least the blade body of one of the blades at a peripheral part thereof in order to support itself against and slide about the axis of rotation along a peripheral part of the other blade.
A pair of saw blades, comprising:
- a first blade, adapted to rotate in a first direction about an axis of rotation;
- a second blade, adapted to rotate in a second direction opposite to said first direction about the same axis of rotation, wherein each blade includes a blade body and cutting elements, arranged along the periphery of the blade body and adapted to run proximate to each other when the blades are contra-rotating;
- and
- a spacer, extending into a space between the two blades, for attaching to at least the blade body of one of the blades at a peripheral part thereof and for sliding about the axis of rotation along a peripheral part of the other blade.
