Abstract
The invention relates to a system and process of the sealing of an area of an object intended to be covered, such as an opening slot, by a sealing strip which becomes adhesive in an excited state when subjected to ultrasound. This procedure comprises the steps of: supplying a sealing strip between an object and a sonotrode having a linear application area; supporting or pressing the linear application area of the sonotrode with the sealing strip to thereby adhere the sealing strip area, which is in contact with the linear application area of the sonotrode, to a corresponding area of the object; and displacing the object in relation to the sonotrode according to a profile of the sealing area, so as to apply the sealing strip to the sealing area of the object.
Claims11
A method for sealing an area of an object, said method comprising the following steps:
- providing an object comprising a sealing area along an opening slot intended to be covered by a sealing strip, the sealing strip comprising a material that is adhesive in an excited state when subjected to ultrasound;
- feeding, by means of a rotating roller, the sealing strip between the object and a sonotrode, the sonotrode comprising an application area that is a line segment;
- supporting or pressing the application area of the sonotrode with the sealing strip to thereby adhere a sealing area of the sealing strip, which is in contact with the application area of the sonotrode, to a corresponding sealing area of the object;
- and
- displacing the object in relation to the sonotrode based, at least in part, on a geometric profile of the sealing area of the object, so as to continuously and evenly apply the sealing strip to the sealing area of the object.
