Abstract: The drier consists of a plurality of nozzles that direct a small volume of air onto the printed image at as high a velocity as possible without disturbing the wet image. The air so delivered while it must be dry, does not have to be heated to effectively dry the image, however, the drying time can be reduced by increasing the air temperature if desired. The use of high velocity air creates what is known is "skin effect" to dry the ink where the outer surface of the ink is quickly dried.

Abstract: A method and system for temporarily halting an article for sensing with a fixed sensing system without altering its average speed. While halted, the article's orientation is manipulated for seeking and presenting a specific area thereon for sensing. The time available for manipulation results from accelerating each article relative to the average speed of articles prior to sensing. The sensing of the article includes visually reading a label thereon to identify the article, and inspection of the article for determining its physical condition. If desired, the physical condition of the article such as a glass bottle may also be evaluated without halting movement thereof. Once the article has been identified and inspected, the article is categorized based on the visual information obtained. Articles in certain categories are rejected from those evaluated.

Abstract: A system for analyzing the physical condition of a moving article, such as a glass bottle, in a stream of articles of manufacture which are moving at a predetermined speed. A light source illuminates a portion of the moving article to be analyzed at an illumination angle, and a camera obtains an image of the illuminated portion of the article. The camera is disposed to view the article at a viewing angle that is distinct from the illumination angle, thereby substantially reducing the amount of reflected light received by the camera. A transparent surface is interposed between the camera and the article and angled to reduce the amount of reflected light received by the camera. A computer or the like processes the image to evaluate the physical condition of the article, and categorizes the article into distinct categories based upon the physical condition of the article.

Abstract: An air knife assembly is disclosed for removing water and soapy lubricants from an area of a bottle or can which is to be labeled or coded using drop marking equipment. The air knife is positioned at the correct pitch, roll and yaw angles to remove water from a desired area only, avoiding damage to labels which have been applied but not yet bonded to the bottle or can. The dewatering ensures accurate marking of the product.
