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).

Abstract: A method of assembling (R, V) a print unit (1, 2) belonging to a printing machine, the print unit (1, 2) comprising a frame (9), a print carriage (7), able to be inserted into and attached to the frame (9), and a doctor blade system (14), independent of the print carriage (7) and able to be attached to said frame (9), comprises the steps consisting in: placing the doctor blade system (14) on an empty transport device (16), inserting said transport device with said doctor blade system (14) into said frame (9), attaching said doctor blade system (14) to said frame (9), removing said empty transport device (16) from said frame (9), inserting said print carriage (7) into said frame (9), and attaching said print carriage (7) to said frame (9).
