Abstract
Self-guiding cutting tool (100) for cutting an adhesive film (20) applied to the roof panel (30) of a car, wherein the roof panel is connected to a side panel (31) of the car by a joint area (32) containing a welding ditch channel, said cutting tool (100) comprising a cutting device (6), at least one guiding means (2) guiding the cutting device (6) over the welding ditch channel of the joint area (32), and at least one transporting means (3) allowing the cutting device (6) to be moved over the welding ditch channel of the joint area (32). Also provided is a method of applying adhesive films to the roof panels of a car using the cutting tool.
Claims19
Method of applying an adhesive film to a roof panel of a car wherein the roof panel is connected to a side panel of the car by a joint area containing a welding ditch channel, comprising the steps of
- attaching the adhesive film to the roof panel of the car without adhering sections of the adhesive film extending from the roof panel over the welding ditch channel towards the side panel;
- cutting off the non-adhered sections of the adhesive film by moving a self-guided cutting tool over the welding ditch channel, said self-guided cutting tool comprising a cutting device, at least one guiding structure guiding the cutting device along the side panel and over the welding ditch channel of the joint area, and at least one transportation structure disposed over the roof panel and allowing the cutting device to be moved over the welding ditch channel of the joint area, wherein the at least one guiding structure is mechanical.
An assembly line comprising an assembled car containing a roof panel and a side panel joined to each other to form a joint area containing a welding ditch channel, an adhesive film applied to the roof panel and a self-guided cutting tool, said self-guided cutting tool comprising a cutting device, at least one guiding structure guiding the cutting device along the side panel and over the welding ditch channel of the joint area, and at least one transportation structure disposed over the roof panel and allowing the cutting device to be moved over the welding ditch channel of the joint area, wherein the at least one guiding structure is mechanical.
