ABSTRACT:
A method for joining pieces of a thermoplastic web material in order to form an expandable cellular block, includes steps of positioning a new piece to be added to the cellular block in opposing face-to-face relation with a last piece most recently previously welded to the cellular block, positioning a heating device having a plurality of heating fingers between the last piece and the new piece and in contact with the opposing surfaces of the pieces, causing the heating fingers to heat the pieces at locations contacted by the heating fingers, and retracting the heating fingers from between the pieces and then pressing the new piece against the last piece such that the new piece is welded to the last piece at the locations heated by the fingers.
