Body mounted door seals are currently supplied to the production line as closed rings or cut to length to fit each individual door opening. In addition, existing seals with a metal core are heavier than the new, self-adhesive products. In future, seals will be available in large rolls. A sensorcontrolled robotic tool will be used to position them around the door opening and they will then be bonded in place, with both pressure and tension accurately predefined. On the side of the seal where the adhesive tape is positioned, there is a thicker area in the middle of the seal which narrows towards the outside. This ensures that the pressure on the seal during the application process is evenly distributed on the adhesive tape. The 'anvil' on the seal functions as a guide rail when the seal and adhesive tape are applied to the door opening. This guide rail fits exactly in the two 'tracks' on the front pressure roll of the tool and allows the seal to be positioned precisely in the door opening. The new process is currently being used to develop and test new adhesive tapes which will allow it to be used in volume production. The strength of the new application system lies in its suitability for almost any type of bodywork and any type of vehicle paint. Other benefits include a weight saving of up to four kilograms per vehicle, a reduction in the cost of the advance preparation of the seal and of the necessary logistics.
