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;
- 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;
- wherein the support structure comprises a cantilever beam extendable along one of the axes;
- and
- wherein the support structure is configured to rotate the support frame about one of the axes.
A device for mounting or dismounting a band-saw blade which, when mounted on a band-saw, has 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 being an outwardly facing outer flat side and the other one being an inwardly facing inner flat side, the device comprising:
- a movable support frame;
- and
- a plurality of retaining elements distributed on the support frame and configured to temporarily adhere 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.
A method of at least one of mounting and dismounting a band-saw blade onto a band-saw or from a band-saw, the band-saw blade having a closed contour when mounted on the band-saw and comprising two opposing narrow sides, at least one of which is provided with a plurality of saw teeth or a cutting material, and two opposing flat sides interconnecting the narrow sides, one of the opposing flat sides being an outwardly facing outer flat side and the other one being an inwardly facing inner flat side, the method comprising the steps of:
- providing a movable support frame having a plurality of retaining elements distributed on the support frame;
- moving the support frame toward the band-saw blade to be mounted or dismounted, which band-saw blade is located at a first location;
- activating the plurality of retaining elements to temporarily attach the retaining elements 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;
- moving the support frame, together with the band-saw blade temporarily attached thereto, from the first location to a second location;
- deactivating the plurality of retaining elements to release the band-saw blade from the support frame and leave the band-saw blade in the second location;
- wherein, when the band-saw blade is mounted, the first location is a storage location for the band-saw blade and the second location is a band-saw, and
- wherein, when the band-saw blade is dismounted, the first location is the band-saw and the second location is the storage location for the band-saw blade.
