摘要:
In a system and method for forming a metal oxide coating on glassware, heated glassware is provided in a coating zone, preferably by a grounded conveyor. An electrostatic charging and depositing field is established to a surface of the glassware in the coating zone, and a flow of metallic vapor is generated and introduced into the electrostatic charging and depositing field. The metallic vapor is electrostatically deposited on the surface of the heated glassware, and reacts with oxygen at the surface of the heated glassware to form a metal oxide coating on the surface of the glassware. The system and method can be used in either cold end coating or hot end coating, and can provide a dual cold end coating with an initial metal oxide cold end coating and a subsequent conventional cold end coating, providing improved surface lubricity at reduced costs.

The present invention inspects the flanges (20) of metal containers (10) that can reliably detect flange defects. The inspection device comprises apparatus (54) for producing an enlarged image of selected portions of the flange (20) with an annular lens (52) between the apparatus (54) and flange (20) and an apparatus (64) for capturing and processing the image. The method involves directing light onto the flange (20) of an article from a light source (28), forming light rays reflected from the flange (20) into radially expanded image of the flange (20) by positioning the annular lens (52) to redirect reflected light rays into the radially expanded image of the flange (20), and providing apparatus (64) for capturing and processing the image to inspect the flange (20) for defects. The annular lens (52) enlarges the image and any defects relative to a pixel of an inspection system.
摘要:
An apparatus for forming a coating on glassware articles comprises a source of pressurized air and source of liquid coating material. The source of liquid coating material includes a reservoir and a vapor-forming chamber. An adjustable gas pressure regulator provides a regulated gas pressure in the reservoir and a regulated flow of liquid coating material out of the reservoir. A plurality of vapor-forming atomizers are positioned and configured to atomize the liquid coating material and direct the coating material vapor into the vapor chamber. The apparatus further includes a vapor booth and a conveyor operable to convey glassware articles to the vapor booth to be coated. A plurality of fans provide circulating flows of coating material vapor within the booth and along the conveyer portion.
