1090-15 METHOD FOR MANUFACTURING A SACK OR BAG WITH AN END BEING RECTANGULAR IN THE FILLED STATE AND WITH A HANDLE, AND A SACK OR BAG MANUFACTURED IN ACCORDANCE WITH SAID METHOD Abstract The present invention refers to a method for manufacturing a sack or bag with an end being rectangular in the filled state and with a handle piece, and sacks or bags manufactured according to said method. For the solution of the object to simplify already known methods, at the end of a tube section with side folds, three parallel, pregrooved fold lines extending transversely to the side edges are formed. Then the end is pulled open and a rectangular cover sheet provided with glue at its circumference is pasted thereinto, at which a flap is formed by folding, wherein the fold edge of the flap lies approximately on one of the two fold lines. After the application of a glued area, the section of the end above one of the two upper fold edges and the flap, the glued surface is glued to the opposite part of the end. Then the grip hole is cut by punching in the glued section between the fold edge and the outer end. After the filling of the sack or bag the open end is sealed in a conventional manner.
