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 dove-tail track is a trapezoid having a parallel top and bottom portion with the width of the bottom portion exceeding the width of the top portion. Interconnecting the top and bottom portion are both a first outer side portion and a second outer side portion. The angle between the top portion and the first outer side portion is a first angle and the angle between the top portion and the second outer side portion 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.
