A method for masking cooling passages of a turbine component having an external surface, an internal cavity for receiving cooling air, and cooling passages extending therebetween. The location and angle of cooling passages are determined using a robotic arm and a location system. A masking device is placed in the cooling passages located during the locating step. The masking device includes a head portion having a gripping feature for gripping by a robotic arm, and a locating feature for orientation of the masking device by the robotic arm. A retaining portion extending from the head portion is arranged and disposed to retain the masking device in a cooling passage. The retaining portion is narrower proximate a distal end than proximate the head portion. The component and head portion of the masking devices are coated. The masking devices may be removed using the robotic arm and locating system.

A method for masking a gap between a closure panel member and a surround, such, for example, as an automobile door arrangement, in which a mask protrudes from the gap and overlies the panel member edge defining a space tapering towards the edge, whereby to feather the paint towards the edge, and masking tapes used in carrying out the method. The masking can be effected by introducing a resiliently deformable elongate strip mask into the gap so as to compress it to be pinched in the gap to protrude therefrom and, after painting, to remove the strip from the gap prior to overpainting. The mask may be introduced with the closure member closed, and needs no adhesive to hold it to the door or surround.

A masking device for masking an opening of a workpiece including a first end, a second end opposite the first end, a longitudinal axis that extends between the first end and the second end, and a cylindrical body extending between the first end and the second end. The cylindrical body has an outer periphery defining the circumferential outermost extent of the cylindrical body. The masking device further includes an aperture extending through the cylindrical body between the first end and the second end. The aperture has an inner periphery defining the circumferential innermost extent of the cylindrical body. The masking device further includes a tab extending away from the first end of cylindrical body along a direction parallel to the longitudinal axis.

A production method of an exhaust gas purification device includes the steps of supplying a solution containing a catalyst metal from a shower nozzle to an upper part of a honeycomb substrate, coating the honeycomb substrate with the solution, and firing the honeycomb substrate coated with the solution, wherein the shower nozzle has a plurality of discharge openings for discharging the solution and a guard which surrounds the plurality of discharge openings.

A masking fixture according to an embodiment of the present disclosure includes an insertion portion fitted into an opening of a workpiece, a covering portion above the insertion portion covering the opening of the workpiece, and an eave portion above the covering portion projecting outwards from an outer edge of the covering portion. In the masking fixture, the eave portion may be arranged higher than the top surface of the workpiece when the insertion portion is fitted into the opening of the workpiece, and a protruding portion may be arranged at the top of the eave portion. The masking fixture may be made of resin.

A paint removal apparatus for cleaning paint from masking devices includes a support base having a plurality of engagement features that are each configured to securely engage at least one paint masking device. A spray nozzle is aimed in a fixed direction toward the support base and configured for spraying a pressurized stream of water at a desired velocity that removes paint from an exterior surface of at least one of the masking devices engaged at the support base. The support base is configured to successively move the masking devices engaged at the engagement features into the pressurized stream of water, such as to provide a generally continuous cleaning operation of masking devices. During movement or rotation of the support base, an exposed portion of the support base may extend from a spray enclosure for removing cleaned plugs from and loading painted plugs onto such an exposed portion.

A device for treating objects, wherein a gap is formed between two wall sections of a treatment chamber. At least one respective component of at least one first and one second working device which can move along the gap, extends from an outer region outside of the treatment chamber through the gap into the treatment chamber. A covering assembly seals the gap in the wall of the treatment chamber, apart from a first through opening and a second through opening, through which the component of the first working device or the component of the second working device extend, and which follow a movement of the component of the first working device or the component of the second working device along the gap. A covering band running on the gap is secured to a first and to a second securing side of the first working device, said first and second securing sides facing one another in the longitudinal direction of the gap. A diverting device, directs the covering band from the first securing side to the second securing side of the first working device, and also from the first securing side of the first working device to the second working device, where it is lifted away from the gap using a lifting device and directed past the second working device.

A stacking device is provided for stacking plugs, in particular paint or installation plugs for motor vehicles, having a housing which has an opening, at at least one axial end, on a front side and in which extend in the axial direction, on an inner wall of the housing, at least two retaining and guide devices for the plugs. The retaining and guiding devices are designed to keep the plugs stacked in position, to allow axial movement of the plugs, and to guide the plugs in the axial direction.

A sealant applying device and a working method thereof, and a sealant applying apparatus are disclosed. The sealant applying device includes a nozzle: the nozzle includes an air inlet portion and a sealant outflow portion, a switch plate is arranged below the sealant outflow portion, the switch plate includes a plate body configured to horizontally move between a first state and a second state, one end of the plate body is provided with a through hole, and a discharge portion is provided at a position corresponding to the through hole and on a side of the plate body facing away from the sealant outflow portion.
