Web support and stabilization unit for a printing head, and printing station equipped therewith

Abstract

A support and stabilization unit (200, 300, 400, 500) for a web (20) advancing in its longitudinal direction over the unit from upstream to downstream; the unit includes in series at least one rotating support roller (31, 32) that is able to come into contact with an underside of the web (20), and at least one device (121, 122, 122′) for tensioning the web (20). The tensioning device (121, 122, 122′) includes a guiding face (121a, 122a) oriented toward the underside of the web (20), an internal cavity connected to the outside of the device via an outlet opening (121d) which is oriented toward the guiding face (121a, 122a), and an air inlet inside the internal cavity (121b), so as to produce, on the web (20), a force (F2) oriented toward the guiding face (121a, 122a).
