Method for using a foil on a printing press and optimizing the maximum usage of the foil

摘要

A method for material deposition employs a printing press, such as those used in cold foil transfers, that permits a greater usage of the foil web than traditional methods. This is achieved by increasing the number of times the foil web is passed through the press, while simultaneously taking into account the area that has not been used and adjusting the impacted area of the foil web accordingly. The foil web is adjusted by using a series of adjustable rollers and angular bars to change the length of the circumferential path the foil takes through the press. By modifying the angle of these rollers and the distance between them, the path can be lengthened or shortened to correspond to the particular needs for a particular print job. This allows the press to use the foil in such a way that reduces foil waste and manufacturer and consumer costs.

主权项

1. A material deposition method comprising:
unwinding a foil web from an unwind core; feeding the foil web through a press wherein
the press has a cold foiler attachment having a sync cartridge wherein, the sync cartridge has a plurality of roller trays, the plurality of roller trays having at least two angular guide assemblies and being operably connected to a plurality of motors wherein,
the plurality of motors provide differing angles to the at least two angular guide assemblies to manipulate the circumference of the foil web in relation to adherence to a substrate; using the sync cartridge to create at least two connected, substantially circular foil raceways for the foil web; applying a layer of adhesive to the substrate; bringing at least two separate sections of the foil web into contact with the substrate more than once; and separating the foil web from the layer of adhesive for a final time,
wherein the foil web is collected upon a rewind core, while the substrate continues through the press.
