Abstract: The invention relates to a calibration tool and a method for calibrating a laser-triangulation measuring system, wherein the calibration tool comprises a tool body that defines a reference plane and that is rotatable relative to the measuring system about a rotation axis perpendicular to said reference plane, wherein the tool body is provided with one or more calibration surfaces that define a pattern of calibration positions, wherein the pattern comprises at least three columns extending in a radial direction away from the rotation axis and at least three rows extending in a circumferential direction about the rotation axis, wherein for each column the calibration positions within said respective column vary in height relative to the reference plane in a height direction perpendicular to said reference plane and wherein for each row the calibration positions within the respective row vary in height in the height direction relative to the reference plane.

Abstract: Provided is a conveyor for conveying a tire component, in particular a tread for retreading, wherein the conveyor includes a support surface that extends in a direction of conveyance to support the tire component during conveyance in the direction of conveyance, wherein the support surface is provided with a surface structure that is arranged to contact seventy-five percent or less than seventy-five percent of the downwardly facing surface area of the tire component, wherein the support surface is arranged to be held stationary during conveyance of the tire component and wherein the conveyor is provided with one or more manipulators to manipulate the position of the tire component on the stationary support surface by sliding the tire component over the stationary support surface.
