ABSTRACT:
A method and apparatus for the automated mass production of glue-chipped glass having a well-defined uniform chipped glass pattern is disclosed which includes pretreating sheets of glass to roughen their surface and then apply a desired amount of glue in a uniform thin layer over the glass by delivering a glue solution to the nip of a pair of rollers where a reservoir of glue is maintained while circulating a heated fluid through the rollers to maintain the glue at a desired temperature. By providing a desired space between the nip of the rollers, the glass sheets being automatically conveyed are coated with a correct amount and thickness of glue layer. The apparatus includes an animal glue solution source (50) and a conveyor (10) for automatically conveying the glass from a glass treating station (20) to an application station (B) whereat a pair of rollers (24, 26) are arranged with a nip (34) therebetween defined by a predetermined space (32) between the rollers. A heated fluid such as water has been found necessary to be circulated through the rollers in order to maintain the properties of the glue such that they can be correctly applied and coated on the glass. The automatic conveyor conveys the glass precisely below the nip of the rollers whereafter the glass is conveyed to an oven (54) where the glue is dried and chips off of the glass to thereby cut the glass and remove portions thereof such that a well-defined chipped glass pattern is created.
