Stacking device for groups of disposable wipes

A stacking device (1) suitable to pack multi-layer packets composed of a specific number of groups (2) of disposable wipes, comprising:

• a tamper (3) for said groups (2) provided with an alternating vertical translation movement;
• a supporting surface (4) of said groups (2) comprising two guides (5) separated by an empty space (S) of lesser width than the width of the groups (2), inside which said groups pass under the thrust of the tamper (3);
• at least a belt (6) to drive and convey said groups (2);
• a lowerator member (7), suitable to receive the groups (2) stacked in packets, to transfer them to a secondary collection belt (15) suitable to convey said packets to a packaging line,
• characterized in that said two guides (5) each comprise a fixed part (5′) and a moving part (5″), wherein each said moving part (5″) is connected to means (8) suitable to generate an alternating horizontal translation movement, synchronized with the alternating vertical translation movement of the tamper (3), so as to increase the empty space (S) separating said two guides (5) during the passage of said groups (2).
