Abstract
In combination with a cutting apparatus having a pair of blades with edges that are closely juxtaposed relative to an axis with each other and where at least one of the blades is movable along the axis to set between axially confronting faces of the blades at the edges a predetermined gap, a system for measuring the gap has a stationary support, and respective means associated with each of the blades for measuring a distance between the support and the face of the respective blade.
Claims18
In combination with a cutting apparatus having a pair of blades with edges that are closely juxtaposed relative to an axis with each other and where at least one of the blades is movable along the axis to set between axially confronting faces of the blades at the edges a predetermined gap, a system for measuring the gap comprising:
- a stationary support;
- and
- respective means associated with each of the blades for measuring a distance between the support and the face of the respective blade.
A cutting apparatus comprising:
- a support;
- a pair of disk blades rotatable on the support about respective parallel axes and having axially confronting faces forming closely juxtaposed outer edges themselves forming a gap;
- means for rotating the blades about the respective axes;
- means for shifting one of the blades axially relative to the other of the blades;
- respective means carried on the support for measuring a distance from the support to the faces of the blades;
- and
- control means for calculating the difference between the measurements and thereby determining a size of the gap.
A method of measuring a gap between confronting faces of blades of a cutting apparatus, the method comprising the steps of:
- measuring a distance from a support to one side of the blades to one of the faces;
- measuring a distance from the support to the other of the faces;
- and
- calculating the difference between the measured distances as the gap.
