摘要:
A drafting equipment is provided with a small double belt for spinning machines with a fiber bundling zone which follows the pair of output rollers of the main drafting field and is followed by a pair of delivery rollers. A pneumatic compression device is provided between the pair of output rollers and the pair of delivery rollers. A pneumatic compression device is provided with a small perforated belt and a suction device extending on the side of the belt away from the fiber sliver and which sucks air through the fiber sliver between the pair of output rollers and the pair of delivery rollers.

A layered structure (1), in particular for production of apparel (50, 70) such as a glove or head covering, comprises at least a first layer (10) and a second layer (20, 22), the second layer including at least a barrier layer (20), and a bonding substance (30) partially disposed between the barrier layer (20) and the first layer (10) to create a bond between the barrier layer and the first layer. The bonding substance (30) includes at least one component (32) of low viscosity such that a force (F) between the first and second layers (10, 20) which acts on at least one of the layers (10, 20) in a force action area (A1) is distributed by a plastic flow onto an area (A2) which is larger than the force action area (A1). More particularly, the bonding substance (30) includes at least one component (32) which is configured such that it has, at 25° C., a shear modulus of not more than 3×105 Pa in accordance with the Dahlquist criterion.

The present invention is an inflatable module which is breathable, i.e. permits the passage of moisture vapor, and which further incorporates a pressure relief means for reducing pressure in the inflated portion should the module be subjected to sudden or excessive stress. In a preferred embodiment of the invention, a pressure relief valve is incorporated as the pressure relief mechanism in the inflatable module. The present invention is further directed to an inflatable module having increased seal strength to make it capable of withstanding the rigors of use.

A layered structure that includes at least a first layer and a second layer is provided. The second layer includes at least one barrier layer. A bonding substance is partially disposed between the barrier layer and the first layer to create a bond between the barrier layer and the first layer. The bonding substance contains a first component that has, at 25° C., a shear modulus of not more than 3×105 Pa in accordance with the Dahlquist criterion. The bonding substance may also contain a second component having adhesive characteristics. The first component also has a low viscosity such that a force (F) between the first and second layers which acts on at least one of the layers in a force action area is distributed by a plastic flow onto an area which is larger than the force action area.
