DEFINITION

Classification: 65/102

(under subclass 17.1) Processes for a process of reshaping or surface deforming a glass preform which has been softened by a disclosed or claimed reheating step, and see the Glossary for a definition of "reshaping" and "surface deforming".

(1) Note. Processes of flattening curved glass preforms are provided for in this subclass.

SEE OR SEARCH THIS CLASS, SUBCLASS:

54+, for a bonding process including a step of reshaping a glass preform prior to assembly or subsequent to bonding.

63+, for a process of sequentially forming, reheating and reworking of glass.

66+, for a process of forming a product from molten glass including a subsequent reworking operation without an intervening reheating step. 67, for a process of forming a sheet and converting the sheet to a hollow article or the process of forming a hollow article and converting it to a sheet.

269+, for reshaping apparatus combined with reheating means.

286+, for reshaping apparatus, per se.
