Abstract
A conditioner roll includes a cylindrical, tubular metal core having four, straight metal flutes, in the form of channel members, extending full length of, and releasably attached to, the core. In one embodiment, each flute is attached by a plurality of bolts extending radially outwardly through and anchored in respective holes provided in the core, the bolts being respectively received in a plurality of holes provided in the flute. A nut is received on a threaded exposed end of each bolt so as to clamp the flute in place. Access holes are provided for permitting installation of the bolts. In a second embodiment, swage nuts are respectively anchored in mounting holes provided in the core for locating each flute, the nuts having been deformed axially, during installation of the flute mounting bolts, to form shoulders located interiorly of the core wall so as to that the nuts stay in place as the bolts are tightened against the flute.
