Seamless Unitary Deflection Member for Making Fibrous Structures Having Increased Surface Area and Process for Making Same

摘要

A seamless unitary deflection member. The seamless unitary deflection member can have a backside defining an X-Y plane and a thickness in a Z-direction. The seamless unitary deflection member can also have a reinforcing member and a plurality of protuberances positioned on the reinforcing member. Each protuberance can have a three-dimensional shape such that any cross-sectional area of the protuberance parallel to the X-Y plane can have an equal or lesser area than any cross-sectional area of the protuberance being a greater distance from the X-Y plane in the Z-direction.
