Abstract: The invention relates to a determination process of the presence of a wire-edge at the site of an internal edge of a ring surface (16) of a ring of a container, comprising: lighting of the ring surface (16) of the container from above, by means of a radial light beam at 360 and its observation according to a peripheral observation field formation in a first image zone, of a first principal circle; and of at least one secondary arc of a circle concentric to the first so-called principal circle, and radially offset relative to the latter. search, in said first image zone, of the first so-called principal circle and any first secondary arc of a circle. The invention also relates to a device for executing such a process and a line comprising such a device.

Abstract: The invention relates to a device and a method for measuring the kinematic characteristics of free fall of a glass gob with four distinct linear cameras each having an observed linear field intercepting the theoretical free fall path, respectively at a first high point of interception and at a first low point of interception, offset from each other according to the theoretical free fall path, and respectively at a second high point of interception and at a second low point of interception, offset from each other along the direction of the theoretical free fall path, the high respectively low optical axes being distinct from each other in projection on a plane perpendicular to the direction of the theoretical free fall path. The invention also comprises a method for controlling a glass article molding installation.

Abstract: A method for marking, at the outlet of a forming machine using a laser beam, a marking area on hot glass containers comprises determining the longitudinal and transverse positions of the marking area of each container by positioning a first optical axis of a first light sensor and a second optical axis of a second light sensor in a non-parallel manner to each other, in a detection plane parallel to the conveying plane of the containers, detecting the instant of intersection or disengagement, by a container, of the first optical axis and the instant of intersection or disengagement, by a container, of the second optical axis, and calculating said transverse and longitudinal positions from these instants and in consideration of a known or constant speed of translation of the containers. The method can determine the marking instant for each container running past the laser apparatus.

Abstract: The invention relates to a method of visualizing the planeness of a ring surface (16) of a container (14), the method consisting in: lighting the ring surface from above using a peripheral incident light beam having radial rays with specular reflection on the ring surface; and using an optical system (24, 124) to form a plane image of the ring surface on a sensor (18), with an optical geometrical transformation that converts a real height difference (dZ) into an image radial offset (dR) on the image, and the image radial offset (dR) corresponding to a unit real height difference (dZ) is greater than the image radial offset corresponding to a real radial offset of the same dimension. The invention also provides a device and an installation implementing such a method.

Abstract: The invention relates to a method of inspecting containers (3) moving between a linear camera and a light source (7) presenting continuous variation of light intensity with a periodic pattern (71) along at least one variation direction (D). According to the invention: for each movement increment of the container, a sequence of N successive image lines of the container is acquired cyclically so that for each image line: the container (3) is illuminated by the light source (7); the image line of the container is acquired; and the periodic pattern (71) is shifted for the next line along the variation direction (D); for each increment of the container (3), at least one phase image line is calculated; and the phase image lines (LP(k)) are analyzed.
