This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with a reinforcing stiffener. The corrugated pipe may include an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. In some embodiments, a stiffener may be positioned within the corrugation valleys. In other embodiments, a stiffener may be positioned within the corrugation crests.

When a laminated gasket product is demolded from a mold in production thereof by a conventional production process, the gasket product is rubbed against the mold and, therefore, minute scratches are formed on a surface of the gasket product. The minute scratches may impair the reliable sealability of a liquid drug. A method for producing a gasket (13) for use in a prefilled syringe (10) includes the steps of: preparing a gasket forming mold; molding a gasket (13) in the mold, the gasket having a surface laminated with a lamination film (15) and including a circumferential surface portion (17); demolding the gasket (13) from the mold, and then simultaneously forming a groove (22) and a projection (24) each extending circumferentially of the gasket in a portion of the lamination film (15) present in the circumferential surface portion (17) of the gasket.

This disclosure relates generally to corrugated pipe, and more particularly to corrugated pipe with an outer wrap. In one embodiment, a pipe includes an axially extended bore defined by a corrugated outer wall having axially adjacent, outwardly-extending corrugation crests, separated by corrugation valleys. The pipe also includes an outer wrap applied to the outer wall. The outer wrap may include fibers and plastic. The outer wrap may span the corrugation crests producing a smooth outer surface.

Methods and systems for applying a protect film to the surface of an electronic device are provided herein. In various aspects, methods and systems disclosed herein can assist the proper alignment of a protective film with the surface of an electronic device desired to be covered.

The present application relates to a protective leather case and a positioning device for protecting a smart terminal. The protective leather case includes a leather layer; an adhesive layer; and a positioning release film including a first release film and a second release film. The leather layer, the adhesive layer and the positioning release film are laminated sequentially. The first release film is provided in a first direction. At least two second release films are provided, and are arranged on both sides of the first release film in a second direction perpendicular to the first direction. The protective leather case can be used to facilitate accurate positioning and lamination between the protective leather case and the smart terminal.

A cast and cure system which can be implemented by UV lacquer and which enables application of various patterns and sheathing on printed materials in areas such as flexible packaging, printing, serigraphy, label printing and offset tin printing. The system includes at least one UV cassette which enables the UV lacquer to pass under the UV light together with the belt and therefore curing the UV lacquer. The system relates to a micro embossing unit with belt-which has at least one cooler cylinder which cools the film coming out of the UV cassette, at least one cylinder which enables the film to be carried during the sheathing and at least one tension control system which automatically adjusts the tension of the cylinders.

According to a method for manufacturing a structure that is provided, it is possible to prevent creases on a skin sheet when the skin sheet and a molten resin sheet are integrally molded using a mold. The method provided by the present invention is a method for manufacturing a structure including the step of integrally molding a skin sheet and a molten resin sheet using a mold. The molding is performed with the skin sheet under tension.

An overlay applicator can include an overlay with a top side and a bottom side. The bottom side can include an adhesive agent configured to adhere to a screen of an electronic device. The overlay applicator can include an adhesive release liner. The adhesive release liner can include a top side and a bottom side. The top side of the adhesive release liner can be removably attached to the bottom side of the overlay. The adhesive release liner can be configured to protect the adhesive agent at the bottom side of the overlay from contaminants. The overlay applicator can include a protective film removably attached to the top side of the overlay. The overlay applicator can include an alignment tab. The alignment tab can include an alignment mechanism. The overlay applicator further can include a pull tab. The pull can include a wiper. Other embodiments are provided.

A bladder mandrel package, used to manufacture a composite structure, includes a mandrel and a wrap ply, surrounding the mandrel to form a wrapped mandrel. The bladder mandrel package also includes a first radius filler, coupled to the wrap ply at a first radius of the wrapped mandrel, and a second radius filler coupled to the wrap ply at a second radius of the wrapped mandrel. The mandrel, the wrap ply, the first radius filler, and the second radius filler are consolidated to from the bladder mandrel package.

Systems and films for protecting surfaces of various substrates, including electronic devices, such as portable electronic devices, include a liner with a strip liner and a main liner. The strip liner, which covers a small strip of adhesive on the back side of a protective film, is configured to be removed before the main liner. With the small strip of adhesive exposed, the protective film may be aligned with a substrate and, if necessary, removed from the substrates and repositioned thereon. Thereafter, the main liner may be removed to enable complete application of the protective film to the substrate. Methods for securing protective films to substrates are also disclosed.
