Publication number: 20210370665Abstract: Offset print apparatus comprises a blanket arranged in a closed loop around a plurality of rollers. Each of the plurality of rollers is rotatable about a respective roller axis to support and convey the blanket around the closed loop. The plurality of rollers comprises: a primary steering roller rotatable about a primary roller axis and being pivotable about a primary steering axis perpendicular to the primary roller axis; and a secondary steering roller rotatable about a secondary roller axis and being pivotable about a secondary steering axis perpendicular to the secondary roller axis. The primary and secondary steering rollers are each independently pivotable. The offset print apparatus further comprises an actuator to actuate pivoting of the primary steering roller and the secondary steering roller.Type: ApplicationFiled: February 22, 2019Publication date: December 2, 2021Applicant: Hewlett-Packard Development Company, L.P.Inventors: Ziv Seemann, Boris Unaeve, Avi Barazani, Israel Katz
