ABSTRACT:
A machine for gas-free sealing/welding of overlapping edges of thermoplastic material is provided and is of the type which includes a framework carrying an ultrasonic transducer horn assembly having a hammer at a lower end thereof. An anvil is positioned below the hammer. A mounting mechanism for mounting the framework for side-to-side movement, and a drive mechanism for moving the framework on the mounting mechanism are also provided. The improvement resides in the mounting mechanism comprising a beam which extends between spaced apart support members and which has at least one upper rail edge and one lower rail edge and wheels rotatably mounted to the framework and including at least one upper wheel and at least one lower wheel which engage, respectively, the upper and lower edges.
Preferably the beam is an I beam mounted on its side with a middle plate portion resting on the support members and transverse end portions of the I beam each having an upper rail edge and a lower rail edge, and the wheels comprise at least two upper wheels and at least two lower wheels mounted to the framework and engaging respective rail edges.
Additionally, an adjustable stop mechanism including a shock absorber is provided, with a mechanism for adjusting the generally vertical position of the shock absorber for adjusting the distnce between the hammer and the anvil also being provided.
