A sheet separation device to open a two-ply sheet includes a rotator; a nipping member disposed opposite the rotator and configured to nip the two-ply sheet with the rotator; a conveyor configured to convey the two-ply sheet between the rotator and the nipping member, and a winding member disposed adjacent to the rotator. The conveyor conveys the two-ply sheet with a bonded portion of the two-ply sheet being an upstream end or a downstream end of the two-ply sheet in a conveyance direction of the two-ply sheet. The winding member winds the two-ply sheet around the rotator, to create a difference in winding circumferential length between the two sheets and separate the two sheets.

A footwear sole structure having a fluid-filled chamber including a tensile member is provided. The fluid-filled chamber includes a first barrier sheet, a second barrier sheet and the tensile member. The first barrier sheet is formed from a first thermoplastic material. The second barrier sheet is attached to the first barrier sheet and is formed from a second thermoplastic material. The first barrier sheet and the second barrier sheet cooperate to define an internal cavity. The tensile member is disposed within the internal cavity and is formed from a third thermoplastic material. A first weld attaches the first barrier sheet, the second barrier sheet, and the tensile member together by melding the first thermoplastic material of the first barrier sheet, the second thermoplastic material of second barrier sheet, and the third thermoplastic material of the tensile member.

Disclosed is a flexible tubular device including a tubular wall that delimits a sealed chamber intended to be filled with a fluid.

An apparatus and method of forming a shell defining a first side and a second side, wherein the shell is formed from a one-piece integral structure, forming an opening configured to provide access to the storage compartment, the opening including a closure device, forming a first carry strap and a second carry strap, forming a plurality of reinforcement patches, and forming a base.

An insulating device backpack may include an outer shell, a first sidewall defining a front portion of the insulating device backpack, and a second sidewall and a third sidewall defining side portions of the insulating device backpack, and a fourth sidewall defining a back portion of the insulating device backpack, an inner liner forming a storage compartment, an insulating layer positioned in between the outer shell and the inner liner, the insulating layer providing insulation for the storage compartment, and an opening configured to allow access to the storage compartment, and a closure adapted to seal the opening.

A container may include a body assembly comprising a shell, an inner liner forming a storage compartment, a foam layer positioned between the shell and the inner liner, and an opening providing access to the storage compartment. The container may also include a lid assembly attached to the body assembly and configured to seal the opening. The lid assembly may include an upper inner liner, an upper insulating portion, and an upper shell portion, and the upper insulating portion may be positioned between the upper inner liner portion and the upper shell portion.

A shaped cross-section composite fiber for an intake filter is manufactured from a single material of polypropylene, without separate binder processing by using the single material of polypropylene as a filter material. The shaped cross-section composite fiber includes: a sheath comprising a reformed polypropylene resin; and a core comprising a polypropylene resin, where the sheath and the core are combined to provide a sheath-core structure.

The present invention provides for a prelam body of a smart card, a smart card, a method of forming a prelam body of a smart card, and a method of forming a smart card. In accordance with some embodiments herein, a prelam body comprises a base substrate formed of at least one layer, and at least one overlay sheet layer formed on one side of the base substrate, wherein the at least one overlay sheet layer has a recess formed therein. The recess is at least partially extending through the at least one overlay sheet layer such that an opening of the recess is exposed.

The present invention relates to a hot-melt adhesive resin film having an excellent adhesive force and durability to various adherends such as metal, glass, and plastic, and a production method thereof. More particularly, the present invention relates to a hot-melt adhesive resin film including a first surface layer, a first intermediate layer, a substrate layer having heat resistance, a second intermediate layer, and a second surface layer, which are laminated in this order, in which the first intermediate layer and the second intermediate layer include a resin which is obtained by modifying a copolymer of propylene and 1-butene with maleic acid, and a production method thereof.
