Abstract: A method for checking tyres. A shift is determined along an acquisition direction between an acquisition point on a surface of a tyre to be checked and a position occupied by the acquisition point following a rotation of the tyre about its rotation axis. A linear laser beam is projected on a linear portion of surface of the tyre, and propagates in a direction parallel to the acquisition direction. A matrix image of a matrix portion of surface of the tyre containing the linear portion of surface is acquired; the image containing a laser line reflected by the linear portion of surface. A sub-portion of the matrix image is determined as a function of the determined shift, containing the reflected laser line. The sub-portion of the matrix image is then processed to determine an elevation profile of the linear portion of surface.

Abstract: A method for controlling a manufacturing process of components of a tire for vehicle wheels, wherein at least one elongated element fed by a dispensing member is distributed onto a forming support by means of at least one pressing member acting on the at least one elongated element along a pressing direction. The method includes the steps of substantially continuously detecting the value of a characteristic quantity indicative of the displacement of the at least one pressing member along the pressing direction, comparing the detected value of the characteristic quantity with a threshold value and generating a warning signal when the detected value of the characteristic quantity exceeds the threshold value. Such a control method allows the presence of possible deposition anomalies to be identified right from the deposition step of the elongated elements on the forming support so as to ensure ever higher quality levels in tires manufactured through continuous processes.
