Abstract: When vehicle wheels are powder-coated with powder coating, those surfaces on which no coating is wanted are always also coated. To suck off the powder coating from these surface areas before it is baked in, a device which includes a conveyor system, an electronic camera and a suction station is used. The electronic camera records the axial and angular position of the vehicle wheels which pass it, and supplies corresponding data to a controller. After a certain time delay, this causes a suction head in the suction station to move, in such a way that it approaches the vehicle wheel with appropriate alignment of its axis and angular position, and using suction nozzles sucks off those surfaces of the vehicle wheel on which the powder coating is not wanted. During the suction process, the suction head moves together with the vehicle wheel, at the same speed.

Abstract: A method for adhering a member and an apparatus for adhering the member to a base is useful for preventing warping of the member and non-uniformity of the strength of adhesion. After the adhesive application unit is positioned at a first position at a fixed distance from an initial application position of the base, movement of the unit is started from the first position with the moving unit while the action of discharging adhesive of the application unit is started. Next, the action of discharging adhesive of the application unit is completed at the final application position of the base and the movement is stopped at a second position at a fixed distance from the final application position of the base. This results in movement of the application unit at a constant speed from the initial application position to the final application position of the block. Therefore, non-uniformity of the adhesive layer at the initial application position and the final application position of the block can be prevented.
