Problems solved by technology

On the one hand, this guarantees a high precision in the detection of the reflected beam, and a certain simplification in the processing of the obtained signal, but on the other hand, due to the stated limitation of the detection area, this also means that there may be seams possible positioning errors of the light beams, detection neglect of possible defects in the seam area which are sometimes critical for the structure of the carcass and / or waist of a pneumatic tire (or products provided with seams), and the detection of defects in the seam Types of defects that may exist in poor capabilities

Embodiment Construction

[0055] Referring first to Figures 1 to 3, according to the invention, for detecting geometric properties (for example, for dimensional inspection) and / or for detecting seams in sheets 5, 6 of rubber or other flexible material forming a belt or other strip-like product or a device for defects in a seam, comprising a device 1 intended to correspond to at least one source of electromagnetic radiation 2 directed at the seam or seam (obtained, for example, by means of welding), and to detect At least one sensor 3 of radiation reflected or refracted by a seam or seam is placed correspondingly to said seam or seam.

[0056] It should be observed that although means 1 for placing seams or seams corresponding to at least one electromagnetic radiation source 2 and at least one detection sensor 3 are provided and described in the apparatus described here, these means 1 may not be integrated in the In the detection device according to the invention, and may then be provided on another aux...

Abstract

A method for detecting defects in, and / or geometrical characteristics of, at least one joint or splice of sheet pieces, in a unloaded state, characterised by the following steps: a. subjecting said joint or splice to a non-unidirectional electromagnetic radiation; b. performing a two-dimensional detection of the radiation reflected or refracted by said joint or splice; c. generating output signals corresponding to said two-dimensional detection; d. determining possible defects or the geometrical characteristics of at least part of said joint or splice, by analysing, said output signals.

Description

technical field [0001] The present invention relates to a method and apparatus for detecting defects and / or detecting geometrical properties of a joint or splice of two sheets of rubber or other flexible material, the apparatus being particularly suitable for dimensional inspection and detection A joint defect present in a rubber belt used to prepare a carcass and / or a waist of a pneumatic tire for vehicles. Here and below the term "carcass" is generally used to denote a solid structure, for example comprising a sheet of rubber, with or without cords of metal or synthetic material, which is placed under the tread of a pneumatic tire with The term "waist" refers to the reinforcing ring also made of rubber sheets with metal cords, which is inserted between the carcass and the tread and whose purpose is to force the carcass to obtain a flattened shape in radial pneumatic tires . Background technique [0002] In the manufacture of pneumatic tires for vehicles, it is known to m...
