Rebuildable support assembly

In an ultrasonic apparatus for bonding nonwoven products, such as diapers, incontinent garments, sanitary items, and the like;

• and including an ultrasonic converter for converting electrical energy to vibrational kinetic energy, an ultrasonic horn for receiving boosted vibrational kinetic energy, and a generally elongate ultrasonic booster having a longitudinal axis and being connected between said ultrasonic converter and said ultrasonic horn for boosting the vibrational kinetic energy of said ultrasonic converter;
• an ultranoic support assembly for supporting said ultrasonic apparatus, comprising:
• a generally circular modal flange member peripherally disposed radially outwardly about said general elongate ultrasonic booster and having a radially outer surface, said nodal flange member being generally planar with an axis generally perpendicular thereto and generally parallel to the longitudinal axis of said ultrasonic booster,
• an ultrasonic shock-absorbing means peripherally disposed with said generally circular nodal flange member,
• a grip ring means peripherally disposed about said generally circular nodal flange member and said ultrasonic shock-absorbing means for compressively connecting said nodal flange member and said ultrasonic shock-absorbing means together,
• an antirotational means for preventing relative rotation between said grip ring means and said generally circular nodal flange member, said antirotational means comprising a plurality of antirotational pin members radially connected between said grip ring means and said generally circular nodal flange member, and
• a pressure-relief means in said generally circular nodal flange member for eliminating application of longitudinally applied compressive forces against said antirotational pin members, whereby the longitudinally applied compressive forces are absorbed or supported by said grip ring means alone.
