Abstract
An ultra-sonic welding machine has independently adjustable front and rear anvils. Each anvil is independently clampable at desired locations. The rear anvil is reciprocable under power to opened and closed positions relative to the front anvil to thereby permit easy insertion and withdrawal of a workpiece. The end positions of the rear anvil are positively controlled by an adjustable and clampable stop block. The invention further comprises a welding tip that has a concave working edge and relief pockets for improving the welded connection and reducing ultra-sonic energy losses.
