A masking strip for masking the interior surfaces of a gap between two substrates to be painted is provided, the strip comprising: a backing having a first surface and a second surface, the first surface having an adhesive region to fix the masking strip to an interior surface of the gap; a gap filler extending from the backing and adapted to prevent paint flow into the gap; wherein the first surface of the backing is also provided with a spacing means adapted to space the backing of the masking strip away from the interior surface of the gap to which the strip is fixed, and wherein the masking strip is pre-formed.

A mask for deposition for forming a pattern on a transparent substrate according to the present invention includes a mask member having a mask alignment mark penetratedly formed so as to be aligned with a substrate alignment mark formed on the transparent substrate; and an unevenness region formed on one surface of the mask member so as to be adjacent to the mask alignment mark and having protrusions and depressions on a surface thereof. In accordance with embodiments of the present invention, it is possible to prevent the alignment error of the mask from occurring by increasing the recognition rate of the align marks formed on the substrate and the mask. As a result, it is possible to reduce the manufacturing costs by reducing the defective rate of the organic light emitting diode (OLED) display device.

An evaporation mask includes: a mask body including a pattern region configured of a plurality of passage holes; and an adjusting frame configured to hold the mask body and having a mechanism capable of adjusting positions of the passage holes on the mask body. The adjusting frame has a frame-like base material, and a movable member that is provided along one or more sides of the base material to be bonded with an outer edge of the mask body, and at least a part of which is deformable on the base material. One or a plurality of slits are provided at a selective region of the movable member.

A caulk wiping attachment for a caulk gun includes a tube having at least one open end for providing a circular wiping edge. The tube can be attached directly to a barrel of the caulk gun or to a disposable caulk cartridge installed into the barrel of the caulk gun. The tube can be cylindrical with an annular cross section. The tube can be attached to the caulk cartridge using a sleeve slipped over the caulk cartridge, the tube being attached to an outside of the sleeve. A disposable liner or cup can be held within the tube.

A cleaning device includes a supporting mechanism, a clamping mechanism arranged on the supporting mechanism and used to clamp a spray head, a heating mechanism, an adjusting mechanism, and a cleaning mechanism. The heating mechanism, the adjusting mechanism, and the cleaning mechanism are arranged on the supporting mechanism. The heating mechanism is used to heat the spray head clamped by the clamping mechanism. The cleaning mechanism is used to inject cleaning liquid into the spray head, dredge the spray head, and detect the spray head. The adjusting mechanism is used to rotate and adjust a position of the cleaning mechanism to complete different tasks on the spray head.
