The invention provides an apparatus for separating a cone sleeve (4) from a nested stack of cone sleeves (1) the apparatus comprising a chamber (2) having an upper (7) and a lower (8) surface connected by a wall or walls (6), the upper surface (7) having an upper circular opening (3) and the lower surface (8) having a lower circular opening (5) characterized in that the upper circular opening (3) has a circumference of from 100-135% of the maximum circumference of the cone sleeve (4), the lower circular opening (5) has a circumference of from 95-99.5% of the maximum circumference of the cone sleeve (4), and the chamber (2) has inlets (9) connectable to a pressurized gas supply. The invention also provides process that employs the apparatus, the process comprising the steps of providing a stack of nested cone sleeves (1); placing the lowermost end of the stack into the chamber (2) from above the chamber (2); and allowing the lowermost cone sleeve (4) to sit within the lower circular opening (5) and allowing the cone sleeves above the lower-most cone sleeve (4) to protrude from the top of the chamber (2) characterized in that pressurized gas is introduced into the chamber via the inlets (9) thereby to create an elevated pressure within the chamber (2).

An apparatus for separating a cone sleeve (4) from a nested stack of cone sleeves (1), the apparatus comprising a chamber (2) having an upper (7) and a lower (8) surface connected by a wall or walls (6), the upper surface (7) having an upper circular opening (3) and the lower surface (8) having a lower circular opening (5) wherein the ratio of the circumference of the upper circular opening (3) to the circumference of the lower circular opening (5) is at most 1.5:1 wherein the lower circular opening (5) has a circumference from 95 to 99.5% of the maximum circumference of the cone sleeve (4) thereby creating an effective seal between a bottommost cone sleeve and the chamber and wherein the inlets (9) are configured to direct air horizontally or downwards into the chamber and at a rate greater than the air can escape via the upper circular opening so as to create an elevated pressure within the chamber that causes the lowermost cone sleeve to be separated from the rest of the cone sleeve stack.
