Abstract
A belt saw guiding device for a belt saw machine comprises a pair of guide pulleys, a pair of pulleys and a pair of guide rollers. The guide pulleys rotate on the respective axles extending vertically at the lower front right and left sides of a movable frame below which a work piece is to be placed. The pulleys are positioned at the upper rear right and left sides of the frame, respectively and rotate on the axles extending horizontally. Each of the guide rollers is inclined at an angle and arranged between the corresponding pulley and guide pulley. On the inclined guide rollers a belt saw is twisted so as to have its course changed while it runs, driven by the pulleys and the guide pulleys.
Claims1
A band saw comprising in combination:
- a. four upright pillars supporting a channel-shaped frame (2) having two pairs of sleeves slidably mounted thereon and moveable up and down with two pairs of parallel upper (5, 6) and lower bars (4) connecting each pair of sleeves, said frame defining lower and upper frame sections and front and rear ends;
- b. a first set of guide pulleys (7, 7') rotatably mounted toward said front end of said lower frame section with a vertical axle so that said pulleys rotate in the horizontal plane;
- c. a second set of guide pulleys (8, 8') mounted towards said rear end of said upper section with a horizontal axle so that said pulleys rotate in the vertical plane;
- d. a pair of inclined parallel guide rollers (10, 10') held between said lower frame section and said pillars towards said rear end, an endless belt saw (9) extending between said first and second set of guide pulleys and turned 90.degree. by said guide rollers;
- and,
- e. drive means coupled to one of said pulleys to rotate said pulley and drive said band saw.
