Abstract: A rubber or foam type yoga mat whose top surface is formed with lateral ridges or swells running continuously from one side of the mat to the other to provide consistent, easily-cleaned traction for hands and feet without the need for a sticky surface material. In one embodiment, groups of closely-spaced small rounded ridges are formed in the mat surface, either over the full length of the mat or in spaced traction zones for hands and feet. In another embodiment, single wide swells are formed in the mat surface in traction zones, each swell sufficiently wide to support or span a hand or foot. The mat also includes an automatically aligned set of integrated fasteners for securing the mat in a rolled condition.

Abstract: An expandable monofilament pintle, either solid or hollow, that is inserted in a channel formed by a plurality of intermeshed loops at the ends of a papermaking fabric is expanded by means of exposure to either chemicals, high temperature, or some other form of triggering mechanism to pull the fabric ends closer together to form a tight seam.

Abstract: A papermaker's fabric of a type for use in high temperature operations and including interwoven machine direction (MD) and cross-machine direction (CMD) yarns that define a base fabric and a paper support layer. The fabric is characterized by the paper support layer including high temperature MD yarns woven in a repeat pattern that includes a float over at least seven CMD yarns.

Abstract: A papermaker's multilayer fabric having at least top and bottom layers of machine direction yarns which are interwoven with cross machine direction yarns systems to establish a first interwoven fabric layer which is bound to a bottom layer fabric with the two being united by interweaving cross machine direction yarns from the bottom fabric layer in the upper fabric layer. The effective pressing surface area of the first fabric layer being equal to or greater than (x+1)+(0.5y). Wherein (x+1) defines the contribution of the upper fabric layer to the effective pressing surface area and the contribution of the binding yarn is defined by the y factor of the equation. Accordingly, the total effective pressing area is defined by the contributions of the upper ply and the binding yarns.
