Abstract
A band saw includes a continuous saw body and multiple saw teeth provided on an edge portion of said saw body entirely. The edge portion of the saw body and the saw teeth are angled toward an inner side of the saw body by creating a bend near a tooth base line of the saw body. A band saw processing method and a method of manufacturing the band saw are also disclosed.
Claims8
A band saw comprising:
- a continuous saw body;
- and
- multiple saw teeth provided entirely on one of laterally opposite edge portions of said saw body,
- wherein said one of laterally opposite edge portions of said saw body and said saw teeth are angled toward an inner side of said saw body by creating a bend near a tooth base line of said saw body.
A band saw processing apparatus for obtaining a band saw including a continuous saw body and multiple saw teeth provided entirely on one of laterally opposite edge portions of said saw body, wherein said one of laterally opposite edge portions of said saw body and said saw teeth are angled toward an inner side of said saw body by creating a bend near a tooth base line of said saw body, said apparatus comprising:
- a first and a second roller that grasp said band saw from opposite sides of a thickness thereof, said first roller exerting pressure on said band saw from one of said opposite sides, and said second roller exerting pressure on the band saw from an other of opposite sides,
- wherein edges of said first and second rollers are positioned to be offset from each other in an axial direction thereof, and said tooth base line area of said saw body of said band saw is grasped between said edges of said first and second rollers so that said saw teeth and said edge portion of said saw body of said band saw are angled toward said inner side of said saw body.
A method of manufacturing a band saw including a continuous saw body and multiple saw teeth provided entirely on one of laterally opposite edge portions of said saw body, wherein said one of laterally opposite edge portions of said saw body and said saw teeth are angled toward an inner side of said saw body by creating a bend near a tooth base line of said saw body, said method comprising the steps of:
- forming multiple saw teeth on a band saw plate having a long flat plate configuration;
- welding two longitudinal ends of said band saw plate together to form an annular band saw;
- bending said saw tooth base line area of said saw body toward said inner side of said saw body;
- and then shaping said saw teeth.
A band saw teeth setting method for a band saw having a continuous saw body and multiple saw teeth provided entirely on one of laterally opposite edge portions of said saw body, said method comprising the steps of:
- bending said one of laterally opposite edge portions of said saw body and said saw tooth base line area toward said inner side of the saw body when setting teeth for said saw band.
