There is described a process for adhering a first elongate foam element having a first end portion to a second elongate foam element having a second end portion. The process comprises an initial step of melting a first surface portion of the first end portion to produce a first molten portion. Next the first end portion is abutted to the second end portion. Thereafter, the first molten portion is caused to solidify to create a seam bond between the first end portion and the second end portion. Thus, the present invention relates to adhering two elongate foam elements together at their end portions. The bond between the foam elements is created by melting at least a portion of the surface of one or both of the end portions of the two foam buns. This creates insitu a molten region which acts as an adhesive when the end portions of the two buns are abutted or otherwise contacted with each other.
