Abstract
During manufacture of a saw blade (1), especially a circular saw blade (2) or a saw band (14), the size of a deepening (8) in a tooth supporting body (3) of the saw blade (1) is reduced. The tooth supporting body (3) is then connected to a basic body (10) made of a fiber reinforced material to form the base body (12) of the saw blade (1) such that the deepening (8) is closed and the tooth supporting body (3) subjects the basic body (10) to tension when the tooth supporting body (3) and the basic body (10) have the same temperature.
Claims30
A method of producing a saw blade, the saw blade including a base body and a plurality of teeth, the base body including a tooth supporting body and a basic body, the teeth being arranged at the tooth supporting body, the tooth supporting body including a deepening having a size, the basic body being made of a fiber reinforced material, said method comprising the steps of:
- reducing the size of the deepening of the tooth supporting body;
- and
- connecting the tooth supporting body to the basic body to form the base body such that the deepening is closed and the tooth supporting body subjects the basic body to tension when the tooth supporting body and the basic body have the same temperature.
A saw blade, comprising:
- a base body, the base body including a tooth supporting body and a basic body,
- the tooth supporting body including a deepening having a size,
- the basic body being made of a fiber reinforced material,
- the basic body being connected to the tooth supporting body by a process which has reduced the size of the deepening of the tooth supporting body to form the base body of the saw blade such that the deepening is closed and the tooth supporting body subjects the basic body to tension when the tooth supporting body and the basic body have the same temperature;
- and
- a plurality of teeth, the teeth being arranged at the tooth supporting body.
A saw band, comprising:
- an elongated tooth supporting body, the tooth supporting body including a through hole;
- a plurality of teeth, the teeth being arranged at the tooth supporting body;
- and
- a basic body, the basic body being made of a fiber reinforced material and being connected to the tooth supporting body such that the through hole is closed and a base body is formed.
A band saw machine, comprising:
- a saw band, including:
- an elongated tooth supporting body, the tooth supporting body including a through hole,
- a plurality of teeth, the teeth being arranged at the tooth supporting body, and
- a basic body, the basic body being made of a fiber reinforced material and being connected to the tooth supporting body such that the through hole is closed and a base body is formed;
- and
- two wheels,
- the wheels being arranged at a distance with respect to one another,
- the wheels being designed and arranged to guide and to rotatingly drive the saw band,
- the distance between the wheels being designed to be adjustable such that the tooth supporting body subjects the basic body to tension when the tooth supporting body and the basic body of the saw band have the same temperature.
