ABSTRACT:
Disclosed is an apparatus for securing the free end of a roll of fibrous web material to the body of the roll while the roll is uninterruptedly conveyed through the apparatus. The apparatus is particularly useful for securing the free end of fibrous web material which has a pattern-disposition of blockable bonding material disposed in the web for bonding fibers together. The apparatus, in its preferred embodiment, includes a knurled wheel mounted for rotation in a reservoir of moisture for applying moisture to the outside surface of the free end while held against the roll, electrically heated bars positioned for applying heat to the moistened portion of the free end, pressure members positioned opposite the heated bars for passage of the roll between the pressure members and the heated bars to cause pressure to be applied to the roll by the heated bars, a pair of stationarily positioned, spaced-apart elongated guide members for guiding the roll in its axial direction past and into operative contact with the knurled wheel, with the heated bars, and with the pressure members, and paddle means for moving the roll uninterruptedly through the apparatus.
