ABSTRACT:
A device for at least partially encapsulating a border of a substantially sheet shaped element, and including a mould having at least two parts for pressing therebetween the element. The mould has a shape such that, when the element is pressed between the parts of the mould, a cavity is formed around the border. The device has an injection opening for injecting a moulding substance into the cavity. The cavity is formed by an elastically deformable member having a profile which extends along an encapsulation borderline of the element and which is adapted to be elastically deformed while maintaining a tight contact along the encapsulation borderline when pressure is applied thereon in order to follow irregularities in the element along the borderline. Also, a method for at least partially encapsulating a border of a substantially sheet shaped element.
