Abstract:
A tape application device detachably mounted to a workpiece, for applying an adhesive tape released from a release paper onto a tape applying surface provided on the workpiece, comprisinga main body; a sub body spaced from the main body; a first presser roller rotatably supported between the main body and the sub body, so that the adhesive tape is wrapped therearound; a second presser roller disposed in parallel to the first presser roller and capable of being re-positioned relative to the main body and the sub body to be located downstream from the first presser roller as seen in the applying direction of the adhesive tape; a first guide roller mounted to the main body to be rotatable about an axis generally parallel to rotary axes of the first and second presser rollers; a second guide roller mounted to the main body to be rotatable about an axis transverse to the rotary axis of the first guide roller and the rotary axes of the first and second presser rollers, for holding the main body in association with the first guide roller to be movable along the tape applying surface while being engaged therewith so that the first and second guide rollers roll on the tape applying surface while being pressed thereon; a third guide roller disposed in parallel to the second guide roller, for holding the main body in association with the second guide roller and the first guide roller to be movable along the tape applying surface while being engaged therewith so that the first and second presser rollers roll on the tape applying surface while being pressed thereon, and capable of being re-positioned relative to the main body to be disposed in an offset state upstream in the applying direction of the adhesive tape with respect to the first presser roller; a tape guide plate pivoted at a proximal end thereof to the sub body to be rotatable about an axis vertical to the rotary axes of the first and second presser rollers and the second and third guide rollers; and holding means disposed between a distal end of the tape guide plate and the main body, for holding the tape guide plate so that a gap for guiding the adhesive tape-cum-release paper is formed on a side opposite to the second guide roller relative to the presser roller in a manner such that the presser roller is positioned between the second guide roller and the gap.
