<p>A rotating blade guide assembly includes a blade guide carrier and means for rotating the carrier from a first position to a second position. The support structure for the assembly provides a means of supporting the assembly in both positions while allowing an opening for the band to be inserted without twisting in the first position. The first position would be that blade orientation when the blade is placed about a pair of band wheels. The second position would be the blade orientation when the blade is rotated 90° to a cutting position. In this way, the orientation of the blade is changed when the blade guide carrier is rotated from the first position to the second position. The assembly further provides means for securing the blade guide carrier in the second position to provide accurate alignment and prevent rotation of the carrier during use.</p> |
