    摘要: 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.

    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.
