Systems and methods for decorating substrates
Systems and methods for forming and applying decorations onto substrates are disclosed. According to some aspects, a decoration may be formed on a carrier web at a decoration forming station positioned along a web path. The decorations may be transported along the web path to an application station at which the decorations are applied to substrates from the carrier web.
1. A method for decorating a substrate, comprising:
transporting a portion of a carrier web along a web path to a decoration forming station;
forming a decoration on the portion of the carrier web at the decoration forming station, the decoration comprising one or more decoration layers and an adhesive layer formed in register with the one or more decoration layers and exposed on a surface of the decoration facing outwardly from the carrier web;
transporting the decoration along the web path from the decoration forming station to an application station after forming the decoration;
defining a variable path length before the application station through which the carrier web travels to allow accumulation of the carrier web and movement of the carrier web at different speeds at the application station and at another portion of the web path;
stopping movement of the carrier web when the decoration is positioned at the application station to transfer the decoration to the substrate; and
applying the decoration to a substrate at the application station by moving the substrate along the carrier web while movement of the carrier web is stopped and removing the decoration from the carrier web.
2. The method of claim 1 , wherein the adhesive layer is a pressure sensitive adhesive layer.
3. The method of claim 1 , further comprising activating the adhesive layer of the decoration at an activation station positioned along the web path between the decoration forming station and the application station, wherein the adhesive is tacky after being activated.
4. The method of claim 1 , further comprising exposing the decoration to radiation and/or an air flow at one or more curing stations positioned along the web path between the decoration forming station and the application station.
5. The method of claim 4 , wherein at least one curing station of the one or more curing stations is configured to activate the adhesive layer of the decoration such that the adhesive is tacky after being activated.
6. The method of claim 4 , wherein defining the variable path length includes using a festoon to define a variable path length through which the carrier web travels between the decoration forming station and the at least one curing station to allow accumulation of the carrier web.
7. The method of claim 1 , wherein defining the variable path length includes using a festoon to define a variable path length through which the carrier web travels only before the application station to allow accumulation of the carrier web.
8. The method of claim 1 , wherein the carrier web forms a continuous loop.
9. The method of claim 1 , further comprising cleaning the carrier web at a cleaning station positioned along the web path after the application station.
10. The method of claim 1 , wherein forming the decoration at the decoration forming station comprises depositing the one or more layers of the decoration onto the carrier web with an inkjet printer or a flexographic printer.
11. The method of claim 1 , wherein applying the decoration to the substrate at the application station comprises transferring the decoration from the carrier web directly to the substrate.
12. The method of claim 1 , further comprising providing one or more textured features on the carrier web to impart a textural effect to decorations on the carrier web.
13. The method of claim 1 , wherein applying the decoration to the substrate includes moving the substrate relative to the stopped carrier web in a direction along which the carrier web extends at the application station.
