Claim:
A method of packing a product using a flat tubular package, which comprises a top wall ( 4 ), a bottom wall ( 5 ), and two lateral walls ( 6 ), each connected on one side to the top wall ( 4 ) and on the other side to the bottom wall ( 5 ); the method comprising the steps of: engaging the top wall ( 4 ) of the flat tubular package ( 3 ) by suction using a gripping head ( 10 ); moving the gripping head ( 10 ) to feed the flat tubular package ( 3 ) to a seat ( 11 ) engaging the bottom wall ( 5 ) of the flat tubular package ( 3 ) by suction; producing a relative rotation movement between the seat ( 11 ) and the gripping head ( 10 ) to convert the tubular package ( 3 ) from the flat configuration to an open configuration; and inserting the product ( 2 ) inside the open tubular package ( 3 ) wherein the gripping head ( 10 ) engages by suction both the top wall ( 4 ) and a lateral wall ( 6 ) of the flat tubular package ( 3 ); and the gripping head ( 10 ) releases the lateral wall ( 6 ) of the flat tubular package ( 3 ) prior to the step of producing a relative rotation movement between the seat ( 11 ) and the gripping head ( 10 ) to convert the tubular package ( 3 ) from the flat configuration to the open configuration.
