A packaging apparatus for nappies or other soft, flat, folded sanitary articles, comprising:
- packaging arrangement for positioning a plastic film so it is tight against a set of nappies;
- a feeder set up to feed the nappies to the packaging arrangement;
- at least one comb configured to selectively withdraw groups of nappies from a nappy stacker device and place them on the feeder,
- wherein the packaging arrangement comprises a wrapping machine configured to fold a sheet of the film round the set of nappies and to close it on at least three sides of the set of nappies.
A packaging method for nappies or other soft, flat, folded sanitary articles, comprising the following steps:
- withdrawing groups of nappies from a nappy stacker device through the agency of at least one comb and placing the groups of nappies on a feeder;
- feeding a set of nappies comprising one or more groups of nappies to packaging means arrangement;
- positioning a plastic film so it is tight against the set of nappies in order to package the set of nappies itself;
- wherein it comprises the following steps:
- preparing a sheet of the film;
- folding the sheet round the set of nappies in order to wrap it;
- closing the folded sheet on at least three sides of the set of nappies.
A packaging apparatus for nappies or other soft, flat, folded sanitary articles, comprising:
- stacker device for receiving nappies in a continuous succession, and arranging them into groups of nappies;
- packaging arrangement for positioning a plastic film so it is tight against a set of nappies;
- a feeder set up to feed the nappies to the packaging arrangement;
- at least one comb configured to selectively withdraw groups of nappies from the stacker device and place them on the feeder,
- wherein the stacker device comprises a paddle structure forming a closed loop laying in a vertical plane, so that paddles are oriented horizontally at a first position in the loop defining an input station of the stacker and vertically at a second position in the loop defining an output station of the stacker, wherein said paddle structure comprises at least a first and a second group of paddles which are movable along the loop independently one from the other, from the inlet to the outlet and vice versa.
A packaging method for nappies or other soft, flat, folded sanitary articles, comprising the following steps:
- feeding a continuous succession of nappies to a nappy stacker, at an input station of the stacker;
- moving the nappies in groups along the stacker from the input station to an output station of the stacker;
- withdrawing the groups of nappies from the output station of the stacker device through the agency of at least one comb and placing the groups of nappies on a feeder;
- feeding a set of nappies comprising one or more groups of nappies to packaging arrangement;
- positioning a plastic film so it is tight against the set of nappies in order to package the set of nappies itself;
- wherein the groups of nappies are moved in the stacker independently one from the other along a closed loop laying in a vertical plane, so that paddles are oriented horizontally at least at the input station of the stacker and vertically at least at the output station of the stacker.
