S-80/?WT-1 08/1?6 ABSTRACT OF THE DISCLOSURE A papermaker's felt having an elongated base fabric, at least one batt layer, and means to interconnect the opposite longitudinal ends of the base fabric to make an endless felt. The endless felt is made by providing seaming loops on opposite longitudinal ends of the base fabric and bringing the loops into interdigitated engagement on the paper making machine; introducing a core element into the common bight of said loops to connect them; and finally needling the batt layer so that the abutting ends thereof (which abut each other at right angles to the longitudinal direction and obliquely to the thickness direction) are engaged without any opening between them. Marking the paper on the felt is avoided by specially preparing the felt before putting it on the machine, by positioning said seaming loops in longitudinally spaced-apart relationship and inserting shape-retaining wires into the bights of said loops; and needling a batt layer on at least one side of the fabric and between said spaced-apart loops to make the batt layer endless; cutting said batt layer widthwise adjacent the loops of the fabric into flat form; removing the shape-retaining wires from the bights of the seaming loops at the opposite ends and temporarily connecting to loops and cutting away the extra fibrous batt so that the cut ends of the batt may abut one another obliquely to the thickness direction of the batt.
