摘要： Apparatus and process for treating paper strip material to render it particularly adapted to be gathered and enclosed in a wrapper to make a filter cord subdividable into efficient cigarette filters. The paper is first moistened to prevent undue tearing in a longitudinal grooving and lateral stretching treatment which loosens and exposes fibers by passage through the nip between heated meshing rollers of rigid material having alternating circumferential grooves and ridges. After being grooved and stretched the paper is dried to set the grooves, and optionally flattened somewhat by a knurling operation. The grooving and stretching may be carried out by successive sets of rollers wherein the following sets may be operated at a higher peripheral speed to stretch the paper longitudinally.
