Abstract

An oval printing machine includes a guide, defining a closed path (P); one or more supports, movable on the guide, the one or more supports being adapted to support items to be printed; one or more operating stations positioned along the path (P) for processing the items to be printed; at least one digital printing station positioned along the path (P), for printing the items supported by the one or more supports. The digital printing station includes a structure substantially integral with the guide, and a first printing element associated with the structure and movable relative to the structure. The printing element is movable in a first direction (D1) that is transversal to a second direction (D2) in which the guide extends at the digital printing station.

Claims

1. An oval printing machine comprising:

a) a guide, defining a closed path, the guide comprising a first tract and a spaced apart second tract;

b) one or more supports movable on said guide, said one or more supports being adapted to support items to be printed;

c) one or more operating stations positioned along said path for processing said items to be printed, said one or more operating stations comprising at least one silkscreen printing station;

d) at least one digital printing station positioned along said path, for printing the items supported by said one or more supports,

wherein said digital printing station comprises a structure substantially integral with said guide, and a first printing element associated with said structure and movable relative to said structure,

wherein said first printing element is movable in a first direction that is transversal to a second direction in which said guide extends at said digital printing station,

wherein said first printing element is movable between a first position, in which said first printing element executes a printing operation at said first tract of said guide, and a second position spaced apart from the first position, in which said first printing element executes a printing operation at said second tract of said guide,

wherein said first tract is substantially parallel to said second tract,

wherein said one or more supports are moved on said first tract in a third direction, said third direction being parallel to said second direction,

wherein said one or more supports are moved on said second tract in a fourth direction, opposite to said first direction.

2. The printing machine according to claim 1, wherein said one or more operating stations comprise one or more of:

a) a drying station;

b) a flocking station;

c) a foiling station;

d) a fixing station;

e) a preparation station;

f) a station for loading/unloading said items.

3. The printing machine according to claim 1, wherein said first direction is substantially orthogonal to said second direction.

4. The printing machine according to claim 1, wherein said first printing element cannot be substantially moved in said second direction.

5. The printing machine according to claim 1, wherein said first tract and said second tract are located on opposite sides with respect to a median axis of said guide.

6. The printing machine according to claim 1, wherein said guide is partially formed in the structure of said digital printing station.

7. The printing machine according to claim 6, wherein said guide has a first section that extends from said digital printing station, a second section formed in the structure of said digital printing station, and a third section that extends on the opposite side of said digital printing station with respect to said first section.

8. The printing machine according to claim 7, wherein the second section of said guide comprises said first tract and second tract.

9. The printing machine according to claim 1, wherein the structure of said digital printing station comprises:

a) a base;

b) a frame mounted on said base, wherein said frame supports said first printing element for digital printing operations.

10. The printing machine according to claim 9, wherein said frame comprises two uprights extending from respective portions of said base, and a first crosspiece mounted on said uprights, said first printing element being constrained to said first crosspiece.

11. The printing machine according to claim 10, wherein said uprights are located on opposite sides of said guide, so that said first crosspiece extends over two distinct portions of said guide.

12. The printing machine according to claim 11, wherein said distinct portions of said guide are said first tract and said second tract.

13. The printing machine according to claim 1, further comprising:

a) an enclosure, within which said digital printing station is located;

b) an adjustment system for adjusting the humidity and/or temperature within said enclosure.

14. An oval printing machine comprising:

a) a guide, defining a closed path, the guide comprising a first tract and a spaced apart second tract;

b) one or more supports movable on said guide, said one or more supports being adapted to support items to be printed;

c) one or more operating stations positioned along said path for processing said items to be printed, said one or more operating stations comprising at least one silkscreen printing station;

d) at least one digital printing station positioned along said path, for printing the items supported by said one or more supports, wherein said digital printing station comprises a structure substantially integral with said guide, and a first printing element associated with said structure and movable relative to said structure,

wherein said first printing element is movable in a first direction that is transversal to a second direction in which said guide extends at said digital printing station,

wherein said first printing element is movable, along said first direction, between a first position, in which said first printing element executes a printing operation at said first tract of said guide, and a second position spaced apart from said first position, in which said first printing element executes a printing operation at said second tract of said guide,

wherein said first tract and said second tract are located on opposite sides with respect to a median axis of said guide, said median axis being parallel to said second direction,

wherein said first tract is substantially parallel to said second tract,

wherein said one or more supports are moved on said first tract in a third direction, said third direction being parallel to said second direction,

wherein said one or more supports are moved on said second tract in a fourth direction, opposite to said third direction.
