Abstract:
1. A band saw for making straight cuts, comprising: a continuous saw body having an inner side and an outer side, a first pre-mounting straight section that is straight along a width direction, and a second pre-mounting straight section that is straight along the width direction and extending continuous from the first pre-mounting straight section, said saw body being adapted to be suspended between a pair of spaced pulleys, with said inner side facing the pulleys; and multiple saw teeth provided entirely on one edge portion of said saw body and extending from the first pre-mounting straight section, wherein said saw body is subject to tensioning at a tooth base side tension zone located in the second pre-mounting straight section, wherein the first pre-mounting straight section is angled relative to the second pre-mounting straight section at a location immediately next to a tooth base line within a tooth base line area so that the entire saw teeth are angled toward said inner side when the saw body is not subject to tensioning, wherein the tooth base line is located at an innermost part of gullets of the teeth, wherein the tooth base line area is located between the tooth base line and the tooth base tension zone, and wherein the band saw substantially straightens from the one edge portion to an opposite edge portion thereof when the band saw is operationally suspended and tensioned between said spaced pulleys so that the angle formed between the first and second pre-mounting sections substantially disappears.
