Abstract
A vertical band saw machine includes a base, an upright post extending from the base, amounting frame slidably retained relative to the upright post, upper and lower blade mounting pulleys and a tension-equalizing guider pulley rotatably mounted on the mounting frame, the base and the upright post, respectively, an endless band saw blade trained on the pulleys to define upper and lower inclined side paths, and a tension adjusting member disposed to displace the mounting frame between a loosened position to facilitate replacement of the blade, and a tensed position. The guider pulley is brought into synchronized movement with the mounting frame such that the ratio of lengths between the upper and lower inclined side paths is kept unchanged.
