Abstract: The automatic formation and placement of an adhesive component layer on a surface of a holding mechanism in air bag of a air bag device of a motor vehicle, comprises cutting off a planar carrier (2) with a predetermined size and with a peripherally arranged flap (5) from an adhesive tape along a first cutting section up to surface of a base structure (6) by first cutting agents of cutting mechanism for the formation of the adhesive component layer, which is self-adhesive on both the sides on the surface of the holding mechanism for defined support of a component. The automatic formation and placement of an adhesive component layer on a surface of a holding mechanism in air bag of a air bag device of a motor vehicle, comprises cutting off a planar carrier (2) with a predetermined size and with a peripherally arranged flap (5) from an adhesive tape along a first cutting section up to surface of a base structure (6) by first cutting agents of cutting mechanism for the formation of the adhesive component layer, which is self-adhesive on both the sides on the surface of the holding mechanism for defined support of a component with a double-sided, strip-like adhesive layer with an adhesive tape having a surface material. The sides of the self-adhesive layer are bound to the base structure along with the adhesive tap that is arranged to the cutting mechanism. With the help of the second cutting agents, the base structure and the component layer bounded to the carrier are locally cut the flap at the periphery of the carrier along a second cutting section. The flap is cut out from the base structure up to the second cutting section. After the common cutting process, the respective carrier with the flap is further processed by binding as the positive with the adhesive component layer and the base structure, while other areas of the perforated adhesive tape are separated as the negative from the base structure and then taken off from the cutting mechanism. With respect to the local incision at the flap, the same is lifted up from the surface of the base structure by holding at its distal end section along the second cutting section and bent along the direction of the surface material of the carrier by a small degree of angle. The base structure is built in a strip-shaped manner that is elastic while bending. The base structure with a defined number of superimposed carriers with flaps is rolled up for its further processing in the form of a cylinder. The complete carrier is individually removed from the base structure by grasping at the flap and then fed to the holding mechanism and is positioned on its surface. The adhesive component layer corresponds to the geometry of the carrier adhered to the surface. The complete flap and the surface material of the carrier are optionally removed from the adhesive component layer that remains adhered to the surface. An independent claim is included for a carrier band for automatic formation and placement of an adhesive component layer.
