A molding process for the production of a cover wall section for a cover in which the cover wall section has at least one multi-layer fabric that has a reinforcement and, at least on one side, preferably on both sides, a polymer coating, has the following process steps: Provision of at least one multi-layer fabric; draping of the at least one fabric over a molding surface of a mold and stretching of the at least one fabric across the molding surface by at least one tension element; and curing of the at least one fabric and/or the at least one tension element in such a way that the cover wall section is fixed in its shape.

The invention relates to an article comprising a main body (6, 7, 8) that consists of a polymer material having elastic properties, particularly an air spring bellows (2), a metal-rubber element or a vibration damper. In order for fire-retardant properties to be improved, the article is provided, partially or fully, with a cover (9) formed from at least one flat textile structure and/or at least one three-dimensional textile structure and/or at least one shrink film. The cover can be fire-retardant itself or can be equipped to be fire-retardant.

Systems include a creel assembly supporting a plurality of spools containing at least one cord having an indeterminate length such that a plurality of cords are supported on the creel assembly. A tensioner assembly operative to tension approximately equal predetermined lengths of the plurality of cords received from the creel assembly. A building mandrel supported for rotation and translation. A head assembly supported in fixed relation to the building mandrel. The head assembly is positioned co-axially such that the building mandrel can pass through an opening in the head assembly during translation. Methods of manufacture are included, as are flexible spring members and gas spring assemblies.

Disclosed herein are processes for production of a cured polymeric product which processes include using rubber particles to form a rubber layer, applying liquid binder to form a bound layer from the rubber layer, and curing, whereby repetition of steps allows for formation of additional layers and ultimately production of the cured polymeric product.

A method of preparing a cured air spring bellows includes preparing a vulcanizable composition including a eutectic composition by mixing a vulcanizable elastomer, a sulfur-based curative, zinc oxide, and a eutectic composition; preparing a green member using the vulcanizable composition; and curing the green member to form the air spring bellows.

Bellows, for example, a roll bellows and a folding bellows, can be produced that can be used at higher temperatures such as those prevailing in modern articulated constructions, using a mixture comprising at least one thermoplastic elastomer selected from the group of copolysters with a hard segment and a soft segment, wherein in a first step the at least one thermoplastic elastomer is mixed with approximately 0.8 wt. % to approximately 5 wt. % triallyl isocyanurate, based on the total amount of the mixture; in a second step the bellows is produced; and in a third step, the bellows is exposed to an ionizing irradiation in a range from approximately 140 kGy to approximately 350 kGy.

Disclosed in the present invention are a process for producing an anti-gravity balance massage type buffer convection airbag and an airbag cushion. The production process comprises the steps of preparing materials, laminating, preparing an upper cushion body, preparing a lower cushion body, laminating the upper cushion body and the lower cushion body, and shaping to obtain a finished product. The production process and the airbag cushion can produce anti-gravity and buffer convection effects while increasing the force area, and have the effects of balance and massage.

An air spring bellow formed from a rubber composition including a rubber component that contains a polyisoprene rubber and syndiotactic 1,2-polybutadiene. The syndiotactic 1,2-polybutadiene has a low crystallinity of 40 percent or less and the rubber composition includes a filler.

Systems include a creel assembly supporting a plurality of spools containing at least one cord having an indeterminate length such that a plurality of cords are supported on the creel assembly. A tensioner assembly operative to tension approximately equal predetermined lengths of the plurality of cords received from the creel assembly. A building mandrel supported for rotation and translation. A head assembly supported in fixed relation to the building mandrel. The head assembly is positioned co-axially such that the building mandrel can pass through an opening in the head assembly during translation. Methods of manufacture are included, as are flexible spring members and gas spring assemblies.

Various embodiments disclosed relate to drug-coated balloon catheters for treating strictures in body lumens and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.
