Abstract
A tessellated papermakers fabric and elements for making the fabric are disclosed. The elements are formed so as to have male or projection members which interlock with female or recess members. In alternative embodiments, interlocking elements which further utilize pintles for reinforcement of the connection are disclosed. The elements may be molded, extruded, dye stamped or laminated. The desired permeability is provided by forming apertures in the elements and can provide for air and moisture permeability characteristics which vary throughout the fabric. In addition, tessellated fabrics according to the instant invention may be subsequently processed to produce surface or embossing characteristics.
