Abstract

Abstract Apparatus for curing solvent-free inks, coatings and the like in which the apparatus includes moving work, conveyor means for the moving work, an assembly including ultraviolet producing source and reflector partially encasing the ultraviolet producing source and adapted to reflect the radiant energy from the ultraviolet producing source toward the moving work, closable shutter means for blocking the radiant energy from the ultraviolet producing source from impinging upon the moving work when the operation of the system is temporarily interrupted. The reflector, the shutter means, as well as the conveyor, are provided with a plurality of spaced heat pipes contiguously affixed thereto and adapted to cool these elements.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 128 words
In an apparatus for curing radiant energy curable material which apparatus includes moving work to which said radiant energy-curable material is applied, a supporting-conveying means for said moving work, radiant energy means in spaced position relative to said moving work, said radiant energy means comprising an ultraviolet producing source and a reflector partially encasing said ultraviolet producing source and adapted to reflect radiant energy from said ultraviolet producing source toward said moving work, shutter means operable to a closed position relative to said radiant energy means for blocking the radiant energy from said ultraviolet producing source from impinging upon said moving work; the improvement which comprises providing in said apparatus a plurality of spaced heat pipes affixed to said reflector and said shutter means for cooling said elements.
Claim 2
Dependent Claim 128 words
In an apparatus for curing radiant energy curable material which apparatus includes moving work to which said radiant energy-curable material is applied, a supporting-conveying means for said moving work, radiant energy means in spaced position relative to said moving work, said radiant energy means comprising an ultraviolet producing source and a reflector partially encasing said ultraviolet producing source and adapted to reflect radiant energy from said ultraviolet producing source toward said moving work, shutter means operable to a closed position relative to said radiant energy means for blocking the radiant energy from said ultraviolet producing source from impinging upon said moving work; the improvement which comprises providing in said apparatus a plurality of spaced heat pipes affixed to said reflector and said shutter means for cooling said elements.
Claim 3
Dependent Claim 20 words
In an apparatus as in claim 1 wherein a plurality of spaced heat pipes are affixed to said supporting-conveying means.
Claim 4
Dependent Claim 29 words
In an apparatus as in claim 1 wherein said heat pipes are in a generally parallel position relative to the longitudinal axes of said reflector and said shutter means.
Claim 5
Dependent Claim 29 words
In an apparatus as in claim 1 wherein said heat pipes are in a generally inclined position relative to the longitudinal axes of said reflector and said shutter means.
Claim 6
Dependent Claim 17 words
In an apparatus as in claim 1 wherein said heat pipes are embedded in said reflector means.
Claim 7
Dependent Claim 17 words
In an apparatus as in claim 1 wherein said heat pipes are embedded in said shutter means.
