A method for producing a rolling sharpener having at least one grinding or polishing face for grinding and/or polishing a cutting tool, the rolling grinder being formed substantially from two rollers, a grip body to be arranged between the rollers and rotatably relative thereto, and a shaft to be supported rotatably in the grip body. To make correct operation of the rolling grinder user-friendly and to facilitate correct operation overall, each of the rollers is connected to the shaft in a frictionally engaged manner.

Three dimension (3D) model generation systems and methods are operable to generate 3D model data corresponding to images of a physical object of interest that are viewed in a presenting media content event. An exemplary embodiment receives a user request that is associated with an interest by the user to obtain a 3D model of a physical object of interest that is being shown in a scene of a currently presenting media content event. A plurality of video image frames are selected from the scene. Then, 3D model data of the physical object of interest is generated based on at least the selected video image frames of the scene.

A method for producing a roll grinder with two running rollers, a handle body arranged between the running rollers and can be rotated relative thereto, and at least one grinding or polishing surface. The method includes steps of: producing the handle body; measuring the handle body in order to determine the actual dimensions of the handle body; providing at least two differently dimensioned types of spacer elements, by means of each of which a different distance can be set between one of the running rollers and the handle body in the installed state of the roll grinder compared to at least one other type; selecting one of the types of spacer elements provided depending on the measured dimension of the handle body; and connecting the handle body to the running rollers to form the roll grinder while using at least one spacer element of the type selected.

A clamping device for clamping grinding wheels on a driving spindle of a working tool, which includes a rear flange intended to be fitted on the driving spindle in a position proximal to the working tool, wherein the rear flange is provided with a front face with which a first damping element is associated; a front flange intended to be fitted on the driving spindle and provided with a rear face, facing the front face of the rear flange, with which a second damping element is associated; and wherein the front face of the rear flange has a width larger than the rear face of the front flange and the first damping element has a hardness lower than the second damping element.

An abrasive finishing article with an adapter or hub to attach to an appropriate power tool, wherein the hub contains sets of slots to receive ribs positioned on a grinding wheel to permit adjustment of the height of the hub to change the overall height of the grinding wheel and abrasive finishing article.
