Abstract

Abstract A cutting surface for a laser cutter is formed of a plurality of slats assembled into an endless conveyor belt, or alternatively into a slidable tray, for carrying material toward and away from the cutting area. In order to prevent damaging reflection of the laser beam the slats have a honeycomb core held rigid by knifeedged support members.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 243 words
A material handling system for a radiant energy cutter comprising in combination: a. a periodically advancing working surface for supporting and advancing material being cut by a focused beam of radiant energy directed toward said surface, said surface including: 1. a plurality of slats, each including A. an elongate, heat conductive honeycomb core having an open top surface, a pair of long parallel sides aNd a pair of shorter ends; and B. a support member extending along and attached to, each of said sides, each support member having a tapered edge nearest said top surface; 2. means operatively connected to said slat ends to connect said slats into an endless belt in which the support members of adjacent slats extend in closely spaced-apart parallel relationship, said support members being further characterized in that the included angle between the tapered edges of adjacent support members is sufficiently sharp to prevent reflection of said radiant energy back toward said working surface; and 3. means for periodically advancing said belt along a plane, the top surfaces of said slats in said plane forming said working surface; b. means for supporting a bolt of said material rotatably near the upstream end of said surface; c. means for guiding said material from said bolt onto said surface; and d. means for turning said bolt periodically so as to dispense material from said bolt onto said surface at the same linear rate as that at which said surface advances.
Claim 2
Dependent Claim 243 words
A material handling system for a radiant energy cutter comprising in combination: a. a periodically advancing working surface for supporting and advancing material being cut by a focused beam of radiant energy directed toward said surface, said surface including: 1. a plurality of slats, each including A. an elongate, heat conductive honeycomb core having an open top surface, a pair of long parallel sides aNd a pair of shorter ends; and B. a support member extending along and attached to, each of said sides, each support member having a tapered edge nearest said top surface; 2. means operatively connected to said slat ends to connect said slats into an endless belt in which the support members of adjacent slats extend in closely spaced-apart parallel relationship, said support members being further characterized in that the included angle between the tapered edges of adjacent support members is sufficiently sharp to prevent reflection of said radiant energy back toward said working surface; and 3. means for periodically advancing said belt along a plane, the top surfaces of said slats in said plane forming said working surface; b. means for supporting a bolt of said material rotatably near the upstream end of said surface; c. means for guiding said material from said bolt onto said surface; and d. means for turning said bolt periodically so as to dispense material from said bolt onto said surface at the same linear rate as that at which said surface advances.
Claim 3
Dependent Claim 64 words
means operatively connected to said slat ends to connect said slats into an endless belt in which the support members of adjacent slats extend in closely spaced-apart parallel relationship, said support members being further characterized in that the included angle between the tapered edges of adjacent support members is sufficiently sharp to prevent reflection of said radiant energy back toward said working surface; and
Claim 4
Dependent Claim 64 words
means operatively connected to said slat ends to connect said slats into an endless belt in which the support members of adjacent slats extend in closely spaced-apart parallel relationship, said support members being further characterized in that the included angle between the tapered edges of adjacent support members is sufficiently sharp to prevent reflection of said radiant energy back toward said working surface; and
Claim 5
Dependent Claim 82 words
means for periodically advancing said belt along a plane, the top surfaces of said slats in said plane forming said working surface; b. means for supporting a bolt of said material rotatably near the upstream end of said surface; c. means for guiding said material from said bolt onto said surface; and d. means for turning said bolt periodically so as to dispense material from said bolt onto said surface at the same linear rate as that at which said surface advances.
Claim 6
Dependent Claim 82 words
means for periodically advancing said belt along a plane, the top surfaces of said slats in said plane forming said working surface; b. means for supporting a bolt of said material rotatably near the upstream end of said surface; c. means for guiding said material from said bolt onto said surface; and d. means for turning said bolt periodically so as to dispense material from said bolt onto said surface at the same linear rate as that at which said surface advances.
