Abstract

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.

Claims

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.

2. The material deposition method of claim 1 wherein the foil web travels continuously from the start to finish of the method.

3. The material deposition method of claim 1 wherein the foil makes multiple passes through the press at more than one alternate position.

4. The material deposition method of claim 1 wherein the number of raceways is determined by the maximum printing width of the press being used divided by a value determined by a format size of the foiled area.

5. The material deposition method of claim 4 wherein the angles of the at least two angular guide assemblies is increased and the distance between the at least two angular guide assemblies is increased in order to increase the circumference of the foil raceway.

6. The material deposition method of claim 4 wherein the angle of the at least two angular guide assemblies is decreased and the distance between the at least two angular guide assemblies is decreased in order to decrease the circumference of the foil raceway.

7. The material deposition method of claim 1 wherein multiple foil webs having the same or different widths can be run through the press simultaneously.

8. 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 roller trays having at least two angular guide assemblies, the at least two angular guide assemblies are capable of being manually manipulated to a particular angle and distance relative to one another in order to change a length of a path traveled by the foil web through the press;

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,

wherein each of the at least two separate sections of the foil web contact the substrate at different positions; and

separating the foil web from the layer of adhesive for a final time,

wherein the foil web is collected upon a rewind core and the substrate continues through the press.

9. The material deposition method of claim 8 wherein the foil web is continuous from start to finish.

10. The material deposition method of claim 8 wherein the number of raceways is determined by the maximum width of the printing press divided by a value determined by a format size of the foiled area.

11. The material deposition method of claim 10 wherein the angle of the at least two angular guide assemblies and the distance between the at least two angular guide assemblies are increased in order to increase the circumference of the at least two connected, substantially circular foil raceways.

12. The material deposition method of claim 10 wherein the angle of the at least two angular guide assemblies and the distance between the at least two angular guide assemblies are decreased in order to decrease the circumference of the at least two connected, substantially circular foil raceways.

13. The material deposition method of claim 8 wherein the foil web makes multiple passes through the press at more than one alternate position.

14. The material deposition method of claim 8 wherein multiple foil webs having the same or different widths can be run through the press simultaneously.
