摘要:
A permeable belt, a belt press including a roll having an exterior surface and the permeable belt, and a method of drying or pressing a web with the permeable belt. The permeable belt has a paper web facing side and is guided over a support surface. The permeable belt can have a tension of between approximately 20 kN/m and approximately 100 KN/m, a permeability value of between approximately 100 cfm and approximately 1200 cfm, a surface contact area of the paper web side that being between approximately 0.5% and approximately 90% when not under tension, and an open area of between approximately 1.0% and approximately 85%. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.

摘要:
A yoga mat comprising at least one folding depression which enables folding and rolling of a yoga mat so that the width of the mat is typically less than the shoulder width of the user of the yoga mat. The at least one folding depression is typically on the upper, user-contacting surface of the yoga mat. In instances where the overall thickness of the yoga mat is greater than about 0.35 inches, it is advisable to use a location matching folding depression on each side of the yoga mat. The folding depression may be deeper on the user-contacting surface than on the floor contacting surface of the yoga mat. In an alternative embodiment, the upper surface of the yoga mat may be a solid layer, with at least two underlying spaced lower sections to permit folding inward upon the solid layer.
