Abstract
Abstract Ultraviolet light, directed through a character template, forms an image on sensitized tape below. The disc includes a rigid support member having a series of windows formed around its periphery and a series of slots formed radially inward therefrom. A sheet of heat conductive opaque material is bonded to a sheet of transparent backing material and a proportional spacing template and a character template are formed by etching away portions of the conductive sheet. The spacing template is bonded to the support member and operates to alter the length of each opening formed by the slots to thereby control the tape drive mechanism. The character template is also bonded to the support member, with each image, or character in the template positioned under a window.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
103 words
A template for use in label-making machines using ultraviolet light to form images on label material, the combination comprising: a supporting member made of a rigid material adapted for use in label-making machines and having a plurality of windows formed through it; a relatively thin sheet of heat conductive metal attached to one side of the supporting member to cover the windows, the heat conductive sheet having characters formed through it and aligned within the windows; and an ultraviolet light transmitting backing material made of a fluorocarbon polymer and attached to the supporting member to completely cover and protect said heat conductive sheet.
Claim 2
Dependent Claim
36 words
The template as recited in claim 2, wherein the supporting member is disc-shaped, the windows are arranged in a band which extends around the periphery of the disc, and the heat conductive sheet is annular shaped.
Claim 3
Dependent Claim
20 words
The template as recited in claim 3, wherein the supporting member is aluminum and the heat conductive sheet is brass.
Claim 4
Independent Claim
78 words
A method of manufacturing a disc for a label-making machine using ultraviolet light to form images on label material, comprising the steps of: forming windows in a rigid supporting member; bonding a sheet of heat conductive material to a transparent plastic backing material; forming a character template by etching the sheet of heat conductive material; and bonding the character template to one side of the supporting member such that each character formed therein is aligned within a window.
Claim 5
Dependent Claim
71 words
The method as recited in claim 5 wherein spacing slots are formed in said supporting member along with said windows and a proportional spacing template is etched from the heat conductive material along with the character template, said method including the steps of: removing said proportional spacing template from said backing material; and bonding said proportional spacing template to said supporting member to thereby alter the lengths of said spacing slots.
Claim 6
Dependent Claim
144 words
A disc for a label-making machine using ultraviolet light to form images on a label material, the combination comprising: a supporting member made of a rigid material adapted for use in label-making machines and having a plurality of windows and a corresponding plurality of slots formed therethrough; a relatively thin sheet of heat conductive metal attached to one side of the supporting member to cover the windows, the heat conductive sheet having characters formed therethrough and aligned within the windows; an ultraviolet light transmitting backing material attached to the one side of the supporting member to completely cover and protect said heat conductive sheet; and a proportional spacing template attached to the support member, said spacing template having portions which extend into each slot to thereby alter the length thereof in accordance with the width of the character aligned in the slot''s corresponding window.
Claim 7
Independent Claim
94 words
A method of manufacturing a disc for a label-making machine using ultraviolet light to form images on label material, comprising the steps of: forming windows in a rigid supporting member; forming spacing slots in said supporting member; forming a character template and a proportional spacing template from a sheet of heat conductive material; bonding the character template to one side of the supporting member such that each character formed therein is aligned within a window; and bonding the proportional spacing template to the supporting member to thereby alter the lengths of the spacing slotS.
Claim 8
Dependent Claim
23 words
The method as recited in claim 8 wherein said character template and said proportional spacing template are formed in a single etching process.
