Advanced ultrasonic welding components of U.S. Patent Application 12/925,652 are readily incorporated into new form-fill-seal machines, but owners of existing machines utilizing heat-seal stations were unsuccessful at swapping the sealing packages. Retrofit kits (10) to replace heat sealing stations with advanced ultrasonic sonotrode (13) and anvil 812) include: a housing (20,21,22,23,24); a linear rail (50) fixed thereto; first and second bearing carriages (61,62) being slidable upon the rail; and first and second fluidic muscles (16,17). Each of the fluidic muscles is mounted with a first end fixed to a respective housing wall (21,22), and a second end fixed to a respective bearing carriage, permitting actuation of each carriage through pressurization and depressurization of the muscles. The advanced anvil and sonotrode may be secured to respective carriages. In-line arrangements of anvil/sonotrode, bearing carriages, the first fluidic muscle, and the second fluidic muscle provides a narrow profile, permitting side-by-side kit installations for retrofits accomplishing duplex sealing on a horizontal machine. |
