ABSTRACT:
A needle punched papermaking felt is described which comprises a plurality of layers of foundation fabrics formed in an endless form by joining the opposite edges of long woven form foundation fabrics or foundation fabrics woven in an endless form, laying over one or both sides of said foundation fabrics batts consisting of synthetic fibers or natural fibers or mixtures thereof, and by felting by a needle punching process to cause the component fibers to be entangled with each other. A thin layer of batts consisting of synthetic fibers, natural fibers or their mixtures, may be interposed between the adjacent layers of the foundation fabrics. The method of manufacture comprises the steps of placing in a needle punching machine under tension, a plurality of endless foundation fabrics in a long woven form, or a plurality of relatively easily woven foundation fabrics in an endless form, or both, applying and laying batts consisting of synthetic fibers or natural fibers or their mixtures over the foundation fabrics while the foundation fabrics are being advanced in the needle punching machine, and needle punching the combination of the superimposed foundation fabrics and batts so that the component fibers are caused to be entangled with each other.
