1. An anvil for an ultrasonic welding device, the anvil comprising:
a working surface formed on the anvil for resting an object to be welded by ultrasonic oscillations; and
a bearing surface formed on the anvil;
wherein the bearing surface comprises two portions not parallel to each other for resting the anvil on a support surface formed on an anvil carrier;
wherein the two portions at least partially form an angle, α, in the range of 150° to 30° in an intermediate space lying between the two portions, and wherein the intermediate space lies outside the anvil;
wherein an angle, δ, is formed between a plane in which the working surface lies, and a first portion of the two portions of the bearing surface and an angle, ε, is formed between the plane in which the working surface lies, and a second portion of the two portions of the bearing surface; and
wherein α+δ+ε is substantially equal to 180°.
