Method and system for applying a fluid discharged from a slot-die head to one or more advancing substrates

A system for applying a fluid to one or more moving substrates, said substrate(s) having a front surface, a back surface, edge surfaces between the front and back surfaces, a maximum width, a maximum length, and a thickness;

• wherein the system comprises:
• a slot-die head holding a discharge slot and a meniscus guide with a bottom part of the meniscus guide extending below the discharge slot;
• an adhesive substrate carrier tape having an adhesive front surface and a non-adhesive back surface, said carrier tape holding the one or more substrates on its front surface, and said carrier tape being configured for providing a substantially sealed connection between the back surface of the one or more substrates and the front surface of the carrier tape;
• a roll system for advancing the carrier tape holding the one or more substrates in a machine direction past the discharge slot of the slot-die head;
• and
• an alignment support for supporting the back surface of the carrier tape to maintain a predetermined distance between the front surface of the carrier tape and a bottom edge of the meniscus guide and thereby to maintain a distance between the front surface of the substrate(s) and the bottom edge of the meniscus guide when advancing the carrier tape holding the one or more substrates in a machine direction past the discharge slot of the slot-die head.
