Abstract: A stand having a stand head for holding an object, having a stand column which supports the stand head and stands with its lower end on the ground, having at least one support leg which stands with its free end on the ground and supports the stand column, having a first joint which connects the support legs to the stand column in a movable fashion, such that the inclination of the stand column can be set by means of an adjustment of the first joint, and having a detachable leg locking arrangement which locks the support leg in a defined position relative to the stand column, wherein a counterweight is attached to the lower end of the stand column.

Abstract: A device for placing a curable liquid coating material onto a surface to produce a peel-off protective layer. The device includes a spray nozzle adapted to spray the curable liquid coating material onto an area of the surface. The spray nozzle and the surface are movable relative to each other. An applicator nozzle is positioned adjacent to the spray nozzle. The applicator nozzle and the surface are movable relative to each other. The applicator nozzle applies the curable liquid coating material onto the surface adjacent to a lateral edge of the area.

Abstract: A process for producing a peel-off protective layer for surfaces, especially for painted surfaces of motor vehicle bodies. A curable liquid coating material is sprayed by a spray nozzle onto the surface to be protected, where it forms a two-dimensional protective layer which cures. Coating material emerging essentially as a continuous strand or strip of material from an applicator nozzle is applied to the surface to be coated at the edges of the areas of the coating material which has been sprayed onto the surface.
