Abstract The present invention relates to a tool for tensioning a tape wrapped around an object and cutting off the surplus when a preset tension has been reached in the tape, said tool comprising a displaceable handlever having a given range of travel, means for gripping and tensioning the tape, cutting means operatively associated with the handlever for being operated when the tape tension exceeds a predetermined value to cut the tape, coupling means between said handlever and the gripping and tensioning means and having an engaged state to cause tensioning of the tape as the handlever is displaced, and having a disengaged state at a predetermined tension in the tape, and stop means to limit displacement of the handlever to a restricted portion of the range of travel of the handlever with the coupling means in engaged state, said handlever being operatively positioned to actuate the cutting means only when the handlever is beyond the restricted portion of the range of travel after the coupling means is in disengaged state. According to the invention the coupling means includes a pull rod provided with a recess in one longitudinal edge and, a slide moveable in the longitudinal direction of the pull rod and carrying a runner which is guided to be moveable with respect to the slide transversely of the longitudinal direction of the pull rod and immoveable with respect to the slide in the longitudinal direction of the pull rod and which is resiliently urged against that edge of the pull rod provided with the recess.
A tool for tensioning a tape wrapped around an object and cutting off the surplus when a pre-set tension has been reached in the tape, said tool comprising a displaceable handlever having a given range of travel, means for gripping and tensioning the tape, cutting means operatively associated with the handlever for being operated when the tape tension exceeds a predetermined value to cut the tape, coupling means between said handlever and the gripping and tensioning means and having an engaged state to cause tensioning of the tape as the handlever is displaced, and having a disengaged state at a predetermined tension in the tape, and stop means to limit displacement of the handlever to a restricted portion of the range of travel of the handlever with the coupling means in engaged state, said handlever being operatively positioned to actuate the cutting means only when the handlever is beyong the restricted portion of the range of travel after the coupling means is in disengaged state, said coupling means including a pull rod provided with a recess in one longitudinal edge and, a slide moveable in the longitudinal direction of the pull rod and carrying a runner which is guided to be moveable with respect to the slide transversely of the longitudinal direction of the pull rod and immoveable with respect to the slide in the longitudinal direction of the pull rod and which is resiliently urged against that edge of the pull rod provided with the recess.
