Ultrasonic anvil cartridge

An ultrasonic anvil cartridge for use in association with ultrasonic apparatuses for sealing at least two layers of ultrasonic reactive material, of the type having an anvil housing;

• said ultrasonic anvil cartridge cooperating with said anvil housing towards maintaining a substantially even pressure across said at least two layers of ultrasonic reactive coated material as said ultrasonic anvil cartridge and said anvil housing define a sealing region which is operably positioned relative to an ultrasonic wave generator, such that said at least two layers of ultrasonic reactive material are substantially compressed together between said ultrasonic wave generator and said ultrasonic anvil cartridge, said ultrasonic anvil cartridge comprising:
• a plurality of substantially C-shaped support means for maintaining said substantially even pressure across said at least two layers of ultrasonic reactive coated material, said plurality of substantially C-shaped support means constructed of hardened, resilient steel;
• said plurality of substantially C-shaped support means collectively describing a first side, a second side opposite said first side, a substantially concave inside surface and a substantially convex outside surface opposite said concave inside surface;
• said plurality of substantially C-shaped support means being operably aligned so as to be positioned adjacent another in respective succession,
• substantially elastomeric encapsulating means for encapsulating said plurality of substantially C-shaped support means operably positioned within the collective concave surface of said plurality of substantially C-shaped support means collectively to form a unitary cartridge having a substantially convex exterior surface;
• said substantially elastomeric encapsulating means further filling gaps and crevices between adjacent ones of said substantially C-shaped support means to reduce vibration and friction between same.
