Improvement over the apparatus of U.S. Pat. No. 3477102, which apparatus is used for the purpose of producing a rolled wad of material with a string depending from one end of the roll for use as a tampon, which prior apparatus includes a rotatable winding mandrel; a coaxial nonrotating winding tube superimposed on the mandrel; means for reciprocating the tube; means for feeding a textile fiber batting of predetermined size and shape to the apparatus; and means for tying a string about said batting, whereby the rotation of the mandrel with the batting mounted thereon winds the batting about the string tied therearound so as to form a recess in one end of the rolled batting in which the pendant string resides; which improvement comprises the winding tube being of one-piece construction with a guiding curve in the forward end thereof, for guiding the string into its proper position, which guiding curve has a circumference which extends over about 10 DEG to 15 DEG of the winding mandrel and has a radius of curvature of about 2 to 3 mm, and a planar surface extension from the winding tube side in a plane generally parallel to the long axis of the tube having a guiding plate at the forward end thereof whose front edge is substantially perpendicular to the tube long axis and is in the plane of an annular shoulder in the forward end of the tube.
