2 . The band saw of claim 1 , wherein said band saw blade runs through an item to be sawn in a predetermined sawing direction, said blow out device being located at said guide positioned immediately behind said item to be sawn as viewed in said sawing direction.

3 . The band saw of claim 2 , wherein said blow out device is located on a side of said guide facing said item to be sawn.

4 . The band saw of claim 2 , wherein said band saw blade is provided with teeth on a longitudinal side, and that said blow out device directs an air stream on said longitudinal side of said band saw blade opposite said teeth.

5 . The band saw of claim 3 , wherein said guides enclose said band saw blade between them with essentially plane lateral surfaces and with a predetermined distance, said distance being enlarged on a side facing said item to be sawn, such that a first channel each is created on said side between said guides and said band saw blade.

6 . The band saw of claim 5 , wherein said blow out device comprises two second channels for ejecting an air stream, said first channels being flush with said second channels.

7 . The band saw of claim 1 , wherein a wiper each is provided between said guides and said band saw blade.

8 . A band saw comprising a band saw blade running through an item to be sawn in a predetermined feed direction, said band saw blade having a first longitudinal narrow side provided with teeth, a guide for said band saw blade having at least two magnets enclosing within a gap between them lateral broad sides of said band saw blade and exerting a force on said band saw blade for influencing a position in space thereof, means for generating an air stream guided along said teeth for taking along chips, said means being configured as a blow out device connected to said gap and directing said air stream on a second longitudinal narrow side of said band saw blade opposite said first narrow longitudinal side.

9 . The band saw of claim 8 , wherein said blow out device is located at said guide positioned immediately behind said item to be sawn as viewed in said sawing direction.

10 . The band saw of claim 8 , wherein said blow out device is located on a side of said guide facing said item to be sawn.

11 . The band saw of claim 8 , wherein said guides enclose said band saw blade between them with essentially plane lateral surfaces and with a predetermined distance, said distance being enlarged on a side facing said item to be sawn, such that a first channel each is created on said side between said guides and said band saw blade.

12 . The band saw of claim 11 , wherein said blow out device comprises two second channels for ejecting an air stream, said first channels being flush with said second channels.

13 . The band saw of claim 8 , wherein a wiper each is provided between said guides and said band saw blade.
