Abstract
A device for mounting and dismounting a band-saw blade has a movable support frame and a plurality of retaining elements distributed on said support frame and configured to temporarily adhere to the outer flat side of the band-saw blade at various locations along the contour of the band-saw blade, thereby exerting an outwardly directed force on the outer flat side of the band-saw blade.
Claims18
A device for at least one of mounting and dismounting a band-saw blade onto or from a band-saw, the band-saw blade having, when mounted on the band-saw, a closed contour and comprises two opposing narrow sides, at least one of which is provided with a plurality of saw teeth or a cutting material, and comprises two opposing flat sides interconnecting the narrow sides, one of the two opposing flat sides is an outwardly facing outer flat side and the other one is an inwardly facing inner flat side, the device comprising:
- a support frame;
- a support structure configured to support and move the support frame along at least two axes aligned transversely to each other one of which at least two axes being a horizontal axis;
- and
- a plurality of retaining elements distributed on the support frame and configured to selectively attach to the outer flat side of the band-saw blade at various locations along the closed contour of the band-saw blade, thereby exerting an outwardly directed retaining force on the outer flat side of the band-saw blade;
- wherein the support frame is suspended from the support structure and moves with respect to the support structure about the at least two axes;
- wherein the support structure comprises a cantilever beam having a free end extendable along the horizontal axis;
- wherein the support frame is mounted on the free end;
- and
- wherein the support structure is configured to rotate the support frame about the horizontal axis.
