  • Patent number: 9878381
    Abstract: A horizontal band saw machine includes a pair of jaws, a pair of saw blade wheels, a band saw blade looped over the saw blade wheels, a pair of saw blade guides, a contact guide attached to the other of the pair of jaws, a coupling bracket connected to the other of the pair of saw blade guides to locate a distal end thereof below the other of the pair of saw blade wheels, and a follower member provided at the distal end of the coupling bracket. The contact guide and the coupling bracket are configured to move one of the pair of saw blade guides until the follower member contacts with the contact guide when the band saw blade is fed circularly in a state where the band saw blade is clamped by the one of the pair of saw blade guides.

  • Patent number: 9821388
    Abstract: A horizontal band saw machine includes a base, a vertically-movable housing disposed above the base, a pair of wheels that are disposed at a lower portion of the housing and a distance between whose axis lines is changeable, a band saw blade lopped over the pair of wheels, and saw blade guides that are provided on the base. An installation position of the band saw blade is set lower than a cutting end position of a workpiece to be cut by the band saw blade. The housing can move the pair of wheels to the installation position. The pair of wheels can be inserted into an region surrounded by the band saw blade that is set on the saw blade guides when being moved to the installation position with the distance shortened.
