Abstract
This invention relates to an improved double plush knife bearing mechanism for moving a carriage that holds a circular knife along a dove-tail track. The angle between the top portion and a first outer side portion of the dove-tail track is a first angle and the angle between the top portion and a second outer side portion of the dove-tail track is a second angle. The carriage has a bearing mechanism having a first bearing portion with a first component that is positioned adjacent to the top portion of the dove-tail track. There is a second component of the first bearing portion attached to the first component of the first bearing portion or integrally connected thereto and positioned adjacent to the first outer side portion of the dove-tail track at a third angle that is three to eight degrees less than the first angle. There is a second bearing portion that replicates the first bearing portion with two components adjacent the top portion and the second outer side portion of the dove-tail track. There is an arcuate aperture between the first component and the second component of the first bearing portion and an arcuate aperture between the third component and the fourth component …
