  • the protective sheet When the protective sheet is cut, if the cutting property (cutting) is poor, the protective sheet is stretched and becomes resistant to wind, and is easily peeled off during storage and transportation. In addition, when the end portion after cutting is not sufficiently crimped to the inside of the groove, the end portion is resistant to wind, and thus easily peels off.
  • the series of pasting operations described above are required to be finished properly from the functional aspect of protecting the painted surface and the aesthetic aspect after pasting. Therefore, at present, it is affixed by manpower, man-hours and time. However, there is a demand for efficiency in the operation of attaching the protective sheet, and various studies have been made on the method of applying the protective sheet and the cutting method.

Abstract

L'invention concerne une feuille protectrice adhésive qui recouvre une rainure présente dans une partie adhérée, et qui est coupée le long de la rainure, et l'extrémité coupée est collée à une surface côté intérieur de la rainure pour une finition propre. Une lame de coupe et un corps rotatif (3) sont situés dans une poignée facile à prendre en main (2) pour constituer un outil d'adhésion de rainure (1). Le corps rotatif (3) est en forme de disque, une arête (6) dépasse dans la partie centrale dans la direction de l'épaisseur, et le bord extrémité avant constitue la lame de coupe. Le corps rotatif (3) peut couper, le long de rainures présentes sur différentes parties adhérées, des feuilles protectrices adhésives qui passent au-dessus des rainures. L'épaisseur du corps rotatif (3) est conçue pour être plus large que la largeur de la rainure, et une surface inclinée (7) est présente de façon à s'étendre des deux côtés d'un arbre (5) du corps rotatif (3) à partir de l'arête (6). La surface inclinée (7) peut faire coller l'extrémité coupée de la feuille protectrice adhésive coupée par une lame de coupe (61) de l'arête (6) à la surface côté intérieur tout en poussant l'extrémité coupée dans la rainure.
