Provided is a protection film attaching apparatus according to the present invention comprising: a housing; a jig installed on an upper surface of the housing and fixing one side of a protection film; a gripper installed on one side of the housing and elastically supporting another side of the protection film vertically; and a film attaching part installed in the housing to move in a lengthwise direction of the jig so as to pressurize and attach the protection film onto a glass surface of an electronic device. According to the description above, when a protection film is attached onto a surface of glass having curved edges, air bubbles are not generated on the surface of the glass, and an attaching process becomes easier and more effectively done.

A polymer geo-injection apparatus for protecting an underground structure is provided. The apparatus includes: a mechanized vehicle for moving on the ground in order to transport the apparatus while the apparatus forms a subsurface polymer layer that protects the underground structure; a polymer supply tank coupled to the mechanized vehicle and configured to supply solid polymer during the forming of the polymer layer; a polymer melting unit coupled to the mechanized vehicle and configured to receive and melt the supplied solid polymer and to supply the molten polymer during the forming of the polymer layer; and a subsurface ripper coupled to the mechanized vehicle and configured to move through the ground in response to the movement of the mechanized vehicle while receiving and injecting the supplied molten polymer into the ground above the underground structure in order to form the polymer layer and protect the underground structure.

The present invention is directed to tack solutions comprising formic acid, and their use in applying adhesive-coated films to substrates. In particular, paint protection films (PPFs) can be applied to vehicle bodies using the solutions of the present invention.

The present invention relates to a polarizing plate including a polarizer and a polyester film formed on an upper side of the polarizer, wherein the polyester film has a maximum thermal shrink angle of about 10° or less, and any one of a refractive index of x-axis direction nx at a wavelength of 550 nm and a refractive index of y-axis direction ny at a wavelength of 550 nm of about 1.65 or more; a method of preparing the polarizing plate; and a liquid crystal display apparatus comprising the polarizing plate.

The present disclosure provides an anti-corrosive wrapping for a metal pipe (10) (or a metal pipe fitting). The wrapping has an innerwrap (14) including glass fibres which carries a viscoelastic thermoplastic corrosion protection material (13). The wrapping has an outerwrap (16) including glass fibres which is impregnated with an adhesive. The innerwrap (14) is wrappable around the metal pipe (10) with the viscoelastic thermoplastic corrosion protection material (13) carried by the innerwrap (14) engaging and covering an external surface of the metal pipe (10). The outerwrap (16) is wrapped around the innerwrap (13) and the adhesive impregnated in the outerwrap (16) penetrates the innerwrap (13) and thereby adheres the outerwrap (16) to the innerwrap (13).

The invention relates to a high-strength and permanently elastic curable adhesive for bonding at least two surfaces, of which at least one surface is a surface of a permanently elastic plastic, wherein the adhesive is an adhesive that cures in at least two different hardening mechanisms, wherein the first hardening mechanism comprises a chemical reaction to form a chemical bond including a sulphur atom, and the second hardening mechanism comprises the formation of crystalline structures from amorphous polymers. The invention also relates to a method for high-strength and permanently elastic bonding of at least two surfaces to one another, of which at least one surface is that of a permanently elastic plastic, by means of such an adhesive, said method comprising the steps of: applying the adhesive to at least a first of the surfaces to be connected, ensuring conditions under which at least the first hardening mechanism of the adhesive can take place, bringing the first surface into contact with the second surface, and ensuring conditions under which the second hardening mechanism of the adhesive can take place.

A method for manufacturing a vehicle interior trim decorative layer. The method includes: a die cutting step during which at least two parts to be sewn are die cut from a flat film, each of the at least two parts to be sewn having an outer surface and an inner surface opposite to the outer surface; a gluing step during which an adhesion agent is applied, by means of a roller coating machine, on the inner surface of each part to be sewn, and a sewing step during which all parts to be sewn are sewn together along a sewing line by means of a sewing machine so as to form a 3D shaped decorative layer. The decorative layer can be used with a substrate to form a vehicle interior trim. The method enables manufacturing of a 3D shaped decorative layer using a roller coating machine.

Improvements in a graffiti covering skin are disclosed the covering skin is formed from multiple layers of transparent or filtering layers that can be individually removed to provide a new layer without graffiti or damage. Each layer of the skin provides different functions to provide a material that covers existing graffiti and creates a new surface that reduces or repels future graffiti from being placed on the original host surface. One of the layers can be a visual pattern layer that provides the desired appearance of a hard surface of stainless steel, mirror, wood, color, marble, granite or light filtering. This layer provides a structural rigidity that maintains dimensional stability. The skin is backed with a removable adhesive that is removed from the host surface without leaving a residue. Each skin is measured and cut to the desired size before placement in a host surface.

A system and method are provided for conditioning paint roller cover fabric inline in a continuous paint roller manufacturing process. The system and method provide an inline fabric conditioning unit upstream of the point in the process that the paint roller fabric cover strip is wrapped about the outer side of the outer strip, the fabric conditioning unit including a fabric conditioning device that conditions the paint roller fabric cover strip as it is being fed towards the outer side of the outer strip. The fabric conditioning unit may be used to perforate the fabric, to remove loose fibers from the fabric side of the paint roller fabric cover, to buff the paint roller fabric, and to orient the paint roller cover fibers. The continuous paint roller manufacturing process includes steps of feeding an inner strip and an outer strip towards a mandrel, wrapping the inner strip and the outer strip about the mandrel in offset relation, applying a strip adhesive to at least a portion of an outer side of the inner strip and at least a portion of an outer side of the outer strip, feeding a paint roller fabric cover strip having a fabric side and a backing side towards the outer side of the outer strip, the fabric side comprising loose fibers and attached fibers, forming a paint roller tube by wrapping the paint roller fabric cover strip about the outer strip at a point in the process after the strip adhesive has been applied to the outer side of the outer strip such that the backing side contacts the strip adhesive, applying compression to the paint roller tube, and cutting the paint roller tubes into like lengths.
