Abstract
A tool for tightening and melt-adhering a strap, which is light in weight, can be operated by one hand, performs a series of operations, i.e., tightening, pressurizing and frictionally melt-adhering the strap by utilizing power (fluid pressure) instead of manual operation, and which enables the time for frictional melt-adhesion to be adjusted over a wide range and highly precisely with ease, enabling the worker to continue the operation maintaining high efficiency with less fatigue. The tool for tightening and melt-adhering the strap comprises a means for pressing a tightening roller which includes a reversible motor, a means for pressing a vibrator for friction, and a timing mechanism capable of adjusting the time for driving the vibrator over a wide range and finely, which are compactly arranged as a unitary structure.
