Abstract
A device for printing a succession of sheets, includes a platen press for depositing colored or metalized film on each sheet by stamping between a stationary platen and a movable platen. A heating element brings a stamping tool integral with the stationary platen to a given temperature for a stamping operation. The heating element is displaced between an operating position, which is between the stationary platen and each stamping tool associated with that platen, and a maintenance position in which the heating element is outside the platen press.
Claims18
A device for printing a succession of elements in the form of sheets, comprising:
- a platen press configured for depositing a colored or metalized film coming from at least one stamping foil on each sheet;
- the platen press comprising a first platen and an opposing movable platen movable toward and away from the first platen;
- at least one stamping tool on the first platen;
- a heating element located and configured for bringing the stamping tool to a temperature selected so that a stamping operation takes place in a hot environment within the platen press;
- and
- a mounting arrangement configured and operable to hold the heating element in between an operating position in which the heating element is placed between the first platen and the at least one stamping tool on the first platen, and to move the heating element to a maintenance position in which the heating element is arranged outside the platen press;
- wherein the mounting arrangement comprises a heating element transport device configured for transporting the heating element between the operating position and the maintenance position;
- and
- wherein the heating element transport device is further configured and operable for moving the heating element in translation in a direction substantially perpendicular to an inner face of the first platen between the operating position and an intermediate position at which the heating element is arranged between the first and movable platens of the press but spaced at a distance from the platens, and in a direction substantially parallel to the inner face of the first platen between the intermediate position and the maintenance position.

- wherein the mounting arrangement comprises a heating element transport device configured for transporting the heating element between the operating position and the maintenance position;
- further comprising a frame located and configured for supporting each stamping tool associated with the first platen, the frame is mounted on the heating element transport device for moving in displacement between a use position in which the frame extends opposite and in contact with the heating element in the operating position, and an extraction position in which the frame is arranged outside the platen press, wherein the frame is comprised in said transport device and is configured for transporting the heating element between the operating position and the maintenance position when the frame is displaced between the use position and the extraction position;
- wherein said platen press further comprises a stand, wherein the frame is guided through an opening in the stand between the operating position and the maintenance position, the maintenance position being outside of the platen press.
