AMENDED CLAIMS
(received by the International Bureau on
01 September 1982 (01.09.82))

1

(Amended) An arrangement for forming the bottom of a packaging container (1) by folding and sealing the container's bottom wall panels (4, 8, 11) by means of a packaging machine of the type comprising movable drivers (12) for the transfer of tubular packaging container blanks (1) between different processing stations (16, 17, 28, 24, 26, 35), the said arrangement comprising two co-operating folding devices (20) provided on both sides of the plane of motion of the drivers (12) and capable of being driven in opposite directions about mutually parallel aces of rotation (30), characterised in that the axes (30) of the folding devices (20) are at an angle of 10-300 in relation to the momentary position of the longitudinal axis of the drivers (12) which supports the packaging container blank (1) while it is being processed by the folding devices (20).

2

(Amended) An arrangement in accordance with claim 1, characterised in that every folding device (20) comprises two fingers (33, 34) which with a certain mutual displacement project radially from the centre axis of the folding device and between themselves form an angle of 30-600.

1 to 24

Cancelled

25

(New) A method for producing glass including the steps of:

feeding glass batch into a melting furnace near one end of the furnace;

heating the furnace to melt the glass batch;

impinging the surface of the molten glass with a flame of high energy heat from at least one oxy-fuel burner; and

withdrawing molten glass near the other end of the furnace.

26

(New) A method according to claim 25 wherein the flame creates a localized hot spot on the surface of the molten glass.

27

(New) A method according to claims 25 or 26 wherein the flame impinges the surface of the molten glass essentially across the width of the furnace transverse to the flow of molten glass in the furnace.
