Abstract
Abstract A machine and process for forming indicia in or on the surface of objects, particularly friable or hyaline objects, such as glass and ceramics, by producing tape carrying indicia-forming masks, and for applying those masks to the articles to be engraved at a rapid rate, for relatively high volume applications, is disclosed. A die is formed by chemical etching, and is heated to cut an adhesive-backed thermoplastic film on a carrier tape. The masks and the cutout portions are separated, so that both positive and negative masks are produced simultaneously, and either can be applied automatically to objects to be etched and/or embossed. Embossing and/or etching is performed by sandblasting, chemical etching, or selective application of coating materials.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
163 words
An apparatus for applying indicia-forming masks to articles for forming indicia therein or thereon, comprising: means for supporting a roll of indicia-outline bearing tape including at least one carrier tape, at least one transfer tape, and a plurality of indicia outline elements disposed therebetween; said indicia outline elements having an adhesive surface to retain said outline elements to said carrier tape; said transfer tape having an adhesive surface in contact with a non-adhesive surface of said outline elements; means for separating said carrier tape from said indicia-outline bearing tape so that said transfer tape supports said indicia outline elements disposed adjacent said transfer tape; means for supporting a plurality of said articles; means for sequentially and synchronously positioning one of said articles and one of said indicia outline elements on said transfer tape in juxtaposition to each other; and means for pressing said transfer tape against said article so that said indicia outline element adheres to said article forming an indicia-forming mask thereon.
