Abstract

PURPOSE:To perform the bonding of plastic work relatively in a short time as well as obtain a sufficient bonding strength, by providing an automatic value divergence regulating means which regulates adequately the valve divergence of a variable pressure-regulating valve according to the output of a work deformation detecting sensor. CONSTITUTION:A pressure value and a pressing time are entered and set in advance in an automatic valve divergence regulating means 7 by an operator. Besides, the deformation data of a work 1 is to be entered from a work deformation detecting sensor 6 into the automatic valve divergence regulating means 7. The automatic valve divergence regulating means 7 into which each information has been entered processes a computation with a microcomputer and outputs a drive control signal to operate a variable pressure-regulating valve 5 so as to output a required specified pressure from an air cylinder 3. As a result, the air cylinder 3 acts according to an applied air pressure, and the specified static pressure to be applied is varied for the work 1 according to the progress of ultrasonic welding.
