ABSTRACT:
A carrying mechanism repeatedly obtains pieces of thermoplastic material from a supplying mechanism and provides them to a forming mechanism, where they are welded together to form a cellular block. In the forming mechanism, the piece to be added to the block and the piece most recently previously added to the block are arranged in opposing face-to-face relation, and then they are welded together by contemporaneously forming multiple spaced apart and elongate welds therebetween. The welding is performed by positioning heating elements between the piece to be added to the block and the piece most recently previously added to the block to heat laterally spaced apart strips of these pieces, withdrawing the heating elements, and at the same time rolling welding mechanisms along the strips so that the strips are nipped between the rolling welding mechanisms and other welding mechanisms.
