Abstract
A breakaway registration pin (11, FIG. 2) comprises two sections, a first section (21) embedded in a glass art master (10) and a second section (22) bonded by a bonding agent to a top face (33) of the embedded first section (21). The bonding agent has a strength substantially less than the strength of the glass such that the registration pin (11) will break before the glass in art master (10) cracks when a force is applied to second section (22).
Claims9
A breakaway registration pin extending from a hole in a surface of an article wherein the pin comprises:
- a first section, having a cross-sectional area matching that of the hole but slightly undersized with respect thereto and a length no greater than the length of the hole, inserted into the hole and positioned within the hole so that a top face of the section is adjacent to the surface of the article;
- and
- a second section extending above the surface of the article and being bonded to the top face of the first section with a bonding agent having a bond strength between the first and second sections which is less than the strength of the material of the article such that the bond between the first and second sections will break before the article, in which the first section is inserted, is damaged when a force is applied to the bonded second section.
A glass art master for use in placing images on a substrate and having a plurality of registration pins located in the glass for positioning the substrate on a surface of the art master, each of the registration pins comprising:
- a first section embedded in a hole in the glass art master with a top face of the section adjacent to the surface of the art master;
- and
- a second section, bonded to the top face of the first section with a bonding agent which forms a bond between the two sections such that when a force is applied to the second section the bond between the two sections will fail before the glass surrounding the hole in the art master is damaged.
