Ultrasonic sealing anvil

(57) The summary anvil system 36 contains the anvil 20 of 婦 which has the linked cooling systems 39 and 40. Each of the anvil 20 has means 28 and 52 to insulate the anvil main part 23 from the ultrasonic energy emitted from the ultrasonic horn 72 acoustically. Let these interception means 28 and 52 be the space slots 28 which separate the oscillating portion of an anvil from an anvil main part substantially. The anvil 20 has the ceiling pattern 26 which can be adjusted again, and this enables easy exchange of the ceiling pattern 26. The anvil 20 has two or more projection pads 76 again, and these pads reduce the damage done to ultrasonic ceiling equipment and the object part by which a seal is carried out.
