Abstract
A guide for a blade of a bandsaw includes a head and two molded, replaceable shoes that constrain the blade. Each shoe is symmetrical, having four side faces as a thick diamond-shaped frictional border for blade contact. The back of the shoe is a replica of the front. Internal sides of each diamond profile have a resilient web having strips that reversibly lock with grooves against a parallelogram raised from the head surface to retain the shoe carry rubbing forces from the blade. The shoe may be removed, turned through 180 degrees, or flipped over.
Claims9
A blade guide suitable for use as an accessory for a cutting machine of a type having an elongated saw blade in the form of a band held in tension, the blade having two sides and teeth formed along an edge;
- the band being carried across a cutting volume by a motor driving at least one of at least two support pulleys;
- wherein the blade guide consists of a shaft mounted on a frame of the cutting machine in order to support a head in a fixed position relative to the blade of the cutting machine;
- the head is configured so as to form a secure yet reversible interlocking connection with each of two replaceable guide shoes disposed one on each side of the blade;
- each shoe presenting a selected rubbing surface close to an adjacent side of the blade and thereby when in use limiting sideways deflection of the blade within the volume by contact between a side of the blade and an adjacent rubbing surface;
- wherein each replaceable guide shoe may be reversibly mounted on to the head in one of a plurality of orientations thereby providing a plurality of alternative rubbing surfaces.
