A device for measuring a workpiece surface along an X-axis, the measured surface residing generally within an X-Y plane. The measuring device has a ring body supported on a pivot body for pivoting in a limited angular range about a pivot axis spaced from and substantially parallel to the X-axis. The measuring device also has a base fixed in the direction of the Y-axis and a ring body supported on the base for limited movement relative to the base in a direction substantially parallel to the Y-axis. A measurement wheel is rotatable about an axis of rotation defined by the ring body and rolls along the workpiece surface when the workpiece and the measurement device move relative to one another in the direction of the X-axis.

The invention relates to a device and a method for cooling a roll. The roll concerned can be a roller in a roll stand or a measuring roll. The device comprises a cooling shell having a cross section in the shape of a section of a circular arc, for covering a surface region of the roll (200), wherein, in the region of an edge of the cooling shell, a bearing is formed with a pivot joint (120) with an axis of rotation running perpendicular to the circular arc-shaped cross-section, for pivoting the cooling shell about the axis of rotation. According to the invention, in order to ensure that the size of the cooling gap during the rolling operation or during the operation of a measuring roll is always autonomously optimally set, the bearing has a degree of freedom in radial direction r with respect to the circular arc-shaped cross-section of the cooling shell, such that the cooling shell is mounted in the bearing in such a way as to be freely movable in the radial direction.

A measuring wheel may include a wheel assembly comprising a first wheel and a second wheel, a handle operably coupled to a shaft, a housing to which the shaft and the wheel assembly are operably coupled, and a fixed stand disposed at a portion of the housing substantially between the first and second wheels.

A support assembly for a measuring device may include a first retention body, a second retention body, and a wire member having a foot portion, legs and engagement members. The foot portion may extend between distal ends of the legs, and the engagement members may extend from respective proximal ends of the legs. The first and second retention bodies may each include a retaining channel extending at least partially therethrough to receive respective ones of the engagement members. The wire member may be operably coupled to the first and second retention bodies to be transitioned between a retracted state and a deployed state in which the foot member is configured to engage ground upon which the measuring device is operable adjacent to a wheel of the support assembly. The legs and the foot portion may be operably coupled to each other such that tension is increased when the wire member is transitioned between the retracted state and deployed state and is lower in one or both of the retracted state and the deployed state.
