A masking tape may be used for covering a masking area. The masking tape includes a plurality of masking devices coupled together. Each masking device includes a perimeter and an adhesive layer. Each masking device is coupled to at least two laterally adjacent masking devices at given connection points along the perimeter. Each connection point is weak relative to the masking devices. The adhesive layer couples each masking device to a lower adjacent masking device.

A flexible tubular tape product includes a hollow tape tube formed from a spiral wound strip of overlapping pressure sensitive adhesive coated tape. The hollow tube defines an empty interior core space. The outside surface of the hollow tape tube is coated with the pressure sensitive adhesive. A flexible core shaft is positioned inside the interior core space of the hollow tape tube in order to impart some body and ease of handling to the tape tube product.

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 shield device may be secured, without the use of tape, to objects protruding from a surface to be painted in order to mask the objects. One or more magnets are secured around an opening of the shield device for securing to one another or the object. The shield device may also be used to cover parts of vehicles, machines, or other structures for enhancing safety. The shield device may be made of one or more panels of paint-impermeable material define an opening and an interior space extending from the opening toward a distal end of the one or more panels. A slit may extend from the opening partially toward the distal end. The magnets may be spaced apart from one another by a first distance with a second distance between magnets and sides of the slit being smaller.

Methods of manufacturing pre-fabricated insulated wall structures are described in this specification. The methods include (a) attaching a foam panel to a front frame surface of a substantially horizontally positioned frame; (b) placing the frame having the foam panel attached thereto on a track conveyor configured to convey the frame having the foam panel attached thereto in a substantially upright position; (c) conveying the frame having the foam panel attached thereto on the track conveyer in a substantially upright position to a spray foam application station; and (d) spray applying a spray foam composition into a cavity of the frame to form a substantially upright positioned wall structure having a foam layer deposited in the cavity in which the foam layer adheres to the foam panel. Also disclosed are track conveyors suitable for use in such methods.
