Abstract
Abstract CONNECTED PACKAGES ARE FORMED BY A TWO STAGE SEALING PROCESS. A MATERIAL RECEIVING CHAMBER IS FORMED IN THE FIRST STAGE BY COMPLETELY FORMING AN INNER SEAL AND PARTIALLY FORMING AN OUTER PERIPHERAL SEAL. THE CHAMBER IS FILLED WITH MATERIAL SUCH AS COFFEE. THE OUTER PERIPHERAL SEAL IS THEN COMPLETED AS THE FIRST STAGE SEALS ARE MADE IN THE NEXT SUCCEEDING PACKAGE. A SAW TOOTH CUTTER IS EMPLOYED TO WEAKEN THE AREA BETWEEN ADJACENT PACKAGES AND TO COMPLETELY SEVER A PREDETERMINED NUMBER OF THEM.
