Claims14
A method of sealing a panel comprised of a porous material and having a non-planar edge, said method comprising the steps of:
- providing a sealing strip comprising a thermoplastic material;
- providing a sonic head that corresponds to the non-planar edge of the panel;
- placing the sealing strip on the non-planar edge of the panel;
- pressing the sonic head against the sealing strip disposed on the non-planar edge of the panel;
- applying mechanical stimulation to the sealing strip through the sonic head so as to melt the sealing strip;
- and
- moving the sonic head relative to the panel such that the sonic head moves over the sealing strip disposed on the non-planar edge of the panel.
