This fin tip position measurement method comprises: a jig installation step for installing a jig having a flat measurement surface expanded in a circumferential direction and an axial direction to a tip of at least one among a plurality of seal fins that protrude in a radial direction with respect to an axial line, extend in the circumferential direction, and are arranged in a direction in which the axial line extends; a first measurement step for measuring a distance from the axial line to the measurement surface by scanning the measurement surface with a laser beam; and a first calculation step for calculating a distance from the axial line to the tip of the seal fin by adding a radial dimension of the jig to the distance to the measurement surface.

An inspection device for inspecting screw-closures on bottles includes a rotationally-symmetric lens disposed above a bottle's screw-closure and having a convex portion and a flat aspheric portion, a first lighting-unit for illuminating the screw-closure, and a camera located above the lens and connected to an image processor.

The present invention relates to a flow wrapper which comprises a form and/or film tube, which forms the planar film into a film tube and/or fills the film tube with a packaging item and which comprises means to provide a longitudinal- and/or cross-seal to the film tube.

A method of visualizing the planeness of a ring surface of a container includes lighting the ring surface from above using a peripheral incident light beam having radial rays with specular reflection on the ring surface. An optical system is used to form a plane image of the ring surface on a sensor, 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. A device and an installation implementing the visualizing method is also disclosed.

Methods and apparatus for measuring a thickness of a coating on an moving object are provided. Light is directed toward the object at a predetermined location on the object such that a portion of the light interacts with the object. A I D and/or 2D maximum intensities for at least one wavelength channel is captured that is produced by the portion of the light interacting with the object. A measured average intensity of the wavelength channel and/or intensities and their arithmetic derivatives of multi wavelength channel geometries is converted into I D (averaged) and/or 2D thickness values. Based on these values an acceptability of the coating is evaluated and thickness calculated.

An apparatus for determining properties of a laboratory sample container is presented. The apparatus comprises a light source for emitting light to illuminate the laboratory sample container and a number of curved reflecting and/or scattering units. A respective curved reflecting and/or scattering unit comprises a curved shape and is adapted to reflect and/or scatter light of the light source to an outer surface of the laboratory sample container for illuminating the laboratory sample container. The apparatus also comprises a camera adapted to take an image of the laboratory sample container. The image comprises image data related to the laboratory sample container. The apparatus also comprises a control unit adapted to determine the properties of the laboratory sample container based on the image data related to the laboratory sample container.

A method for detecting a covering state of a laboratory sample container is presented. Light is injected into the laboratory sample container and an optical power is measured at a measuring location. A corresponding laboratory sample distribution system is also presented.

Disclosed is a method for inspecting containers provided with closures for checking a sealing function between the closure and a container provided therewith in order to check the sealing function, the at least one spatially resolved image is recorded by the at least one image recording device in such a way that, viewed in the closure direction, a relative position of the closure with respect to the container provided therewith is depicted, and an image evaluation device determines, on the basis of the relative position depicted in the at least one spatially resolved image, at least one sealing variable that is characteristic of performing the sealing function.

Disclosed is a method for inspecting sealing between a closure arranged on a mouth region of a container by performing a screwing-on operation on a mouth region of the container while the container is transported along a transport path, and during transport illuminating the containers by a lighting device and recording at least one spatially resolved image of the container. An image evaluation device determines, on the basis of the relative position depicted in the at least one spatially resolved image, at least one closure rotation angle by which the closure was rotated in the course of the performed screwingin operation, a characteristic closure rotation angle variable.

A device and method for inspecting glass containers and particularly the finish of glass containers is provided. The glass container inspection device includes a rotator rotates a glass container located in an inspection location at least 360 degrees. A first laser source produces a first laser beam which is directed towards the inspection location to form an angle of incidence with the selected glass container being greater than or equal to a critical angle for producing internal reflection of the first laser beam within the selected glass container. A camera is directed at the inspection location to detect light that escapes from the selected glass container as a result of the internally reflected laser beam intersecting a defect in the selected glass container.
