AI Technical Summary

Problems solved by technology

When a sheet is slowed down, said sheet will therefore have a natural tendency to deform, causing wrinkling, which is particularly detrimental to print quality

Embodiment Construction

[0028] For clarity, the same components are denoted by the same reference numerals. Likewise, only those components necessary to facilitate the understanding of the invention are shown schematically and not drawn to scale.

[0029] figure 1 A hot stamping machine 1 for personalized cardboard packaging for the luxury industry is depicted. Commonly referred to as a stamping machine, this stamping machine 1 generally consists of a number of workstations 100 , 200 , 300 , 400 , 500 juxtaposed to each other but interdependent, forming an integrated assembly capable of processing a succession of plate-like supports 10 , 20 . The hot stamping machine thus comprises a feeder 100 , a feed table 200 , a printing unit 300 , a foil feeding and recycling station 400 and a delivery station 500 . A transfer device 600 is also provided to move each sheet of material 10 , 20 individually from the outlet of the feed table 200 to the transfer station 500 , including through the printing device...

Abstract

Device (300) for printing elements in sheet form (10), comprising a platen press (310) for applying to each sheet (10), by stamping, some coloured or metallized film that comes from at least one stamping strip (410), conveyor means using a succession of gripper bars (610) to move each sheet (10) individually through the platen press (310), and a blower member (320) to separate each stamping strip (410) from each sheet (10) leaving the platen press (310). The blower member (320) is mounted so that it can be moved between a work position in which it is able to operate from the transit zone in which the gripper bars (610) travel at the exit of the platen press (310), and a withdrawn position in which it lies away from said transit zone.

Description

technical field [0001] The invention relates to a device for printing boards using hot stamping. [0002] The application of the invention is particularly advantageous in (but not exclusively) the field of packaging for the manufacture of luxury goods. Background technique [0003] The practice of printing text and / or patterns by hot stamping is known, ie one or more colored or metallic films of hot stamping foils (commonly called foil) are applied to a plate-like support with pressure. In the printing industry, vertical die-cutting presses are generally used for this transfer operation, into which the printing supports are introduced piece by piece, while the hot stamping foil is continuously supplied. [0004] In a standard die-cut embossing machine, hot stamping is generally performed between a fixed platen running horizontally and a moving platen mounted for vertical reciprocating motion. Since such die-cut stamping machines are generally automated, a conveyor mechanis...
