Abstract: A method and apparatus for joining multiple layers of materials using an ultrasonic welding apparatus. The ultrasonic welding apparatus utilizes a sonotrode to perform a weld between at least the top and intermediate layer of the multi-layer member. Then, either the multi-layer member or the ultrasonic welding apparatus is rotated such that the bottom layer is positioned adjacent the sonotrode wherein the sonotrode forms a weld between at least the bottom layer and intermediate layer of the multi-layer member. The apparatus includes an ultrasonic welding gun having a C-shape frame including a base portion and a head portion. An ultrasonic welding device, including a sonotrode, is secured to the head portion and an anvil secured to the base portion. The ultrasonic welding gun is connected to a robot operative to position the ultrasonic welding gun to perform the welding operation.

Abstract: The oven includes a muffle 1 in which are mounted at least one upper heating element 11b, 11b, at least one lower heating element 14, an air circulating fan 4 provided in the rear wall 3 of the muffle 1, a heating element 6 placed in the current of air produced by the fan 4, a device 8 for ducting the air in such manner that the air blown by the fan is directed in roughly horizontal streams in the chamber defined by the muffle 1, and an electric switching device. The latter selectively connects the heating elements and the fan to a power supply. This switching device has a given position in which it is capable of connecting the heating element 6 associated with the fan in series with the upper heating element or elements 11a, 11b while connecting the fan 4 and the lower heating element 14 to the supply.
