Abstract
An apparatus and method for accurately setting a cutting gap of a fiber cutting assembly of the type having a cutter reel with a plurality of radially spaced apart, cutting blades and a presser roll mounted adjacent to the cutter reel and having a peripheral surface positioned at a predetermined distance from the cutting edges of the cutting blades to define the cutting gap. The apparatus comprises a gauge member at one of the cutting blade positions which extends radially beyond the radial distance of the blades and corresponds to the desired cutting gap setting, and means for electrically sensing contact of the gauge member with the presser roll.

An apparatus for accurately setting the cutting gap of a fiber cutting assembly of the type having a cutter reel with a plurality of radially spaced apart, outwardly facing cutter blades and a presser roll mounted adjacent to the cutter reel and having a peripheral surface positioned at a predetermined distance from the outwardly facing edges of the cutter blades to define said cutting gap, said apparatus comprising:
- (a) a gauge member at one of the cutting blade positions and extending radially outward beyond the radial distance of the blades and corresponding to the desired cutting gap setting and
- (b) means interconnecting the gauge member and the presser roll for electrically sensing contact of the gauge member with the presser roll.
A method for accurately setting the cutting gap of a fiber cutting assembly of the type having a rotatable cutter reel with a plurality of radially spaced apart, cutting blades and a presser roll mounted adjacent to the cutter reel and having a peripheral surface positioned at a predetermined distance from the edges of the cutting blades to define the cutting gap, said method comprising:
- (a) positioning a gauge member at one of the cutting blade positions, a gauge member which extends radially beyond the radial distance of the cutting blades and a predetermined distance corresponding to the desired cutting gap;
- (b) rotating the cutter reel to bring the gauge member towards the presser roll;
- (c) adjusting the position of the presser roll relative to the cutter reel so as to contact the gauge member with the presser roll;
- and
- (d) sensing electrically the contact of the gauge member and the presser roll so as to indicate when the gap has been acccurately set.
