Patent number: 10377154Abstract: The invention provides a printing system with a transport mechanism for transporting sheets. The transport mechanism comprises: a conveyor body for supporting and conveying a plurality of sheets a transport path; suction means, and especially fan means, for generating an under-pressure at or adjacent to the conveyor body to hold the sheets fixed in position on the conveyor body as it conveys the plurality of sheets along the transport path; and a controller for controlling or regulating operation of the suction means to adjust the under-pressure generated. The controller is configured to control operation of the suction means based on delivery of the plurality of sheets to the conveyor body and/or a change in the delivery of the sheets to the conveyor body. Further, the invention provides a corresponding method of transporting sheets of a print medium in a printing system.Type: GrantFiled: March 31, 2017Date of Patent: August 13, 2019Assignee: OCÉ-TECHNOLOGIES B.V.Inventors: Albert M.

Patent number: 10144227Abstract: A recording substrate treatment apparatus includes transporting mechanism for transporting a sheet of a recording substrate through a first chamber in the interior space of the recording substrate treatment apparatus; a first suction device arranged for removing a gaseous medium from the first chamber; and an impingement device, arranged for providing a first flow of the gaseous medium at the outer surface of the transporting mechanism. The first suction device is fluidly connected to the impingement device, such that in operation the impingement device receives a first flow of the gaseous medium from the first suction device. With this arrangement, the impingement flow is balanced with an air flow directly extracted from the first chamber of the recording substrate treatment apparatus. A printing system including such a recording substrate treatment apparatus and a method of drying a recording substrate using such a recording substrate recording apparatus are also disclosed.Type: GrantFiled: May 26, 2017Date of Patent: December 4, 2018Assignee: OCE-TECHNOLOGIES B.V.Inventors: Hendrikus G. M. Ramackers, Albert M. Van Beek

Patent number: 10053323Abstract: A sheet handling apparatus for a printing system includes a rotary drum having an inner chamber circumferentially surrounded by an outer peripheral wall with perforations formed therein. By means of sucking an air flow through the perforations of the drum to a suction system, sheets are attracted to the peripheral wall of the drum. A stationary shutter member is positioned inside the inner chamber for blocking the flow of air through the perforations when they pass, with the rotation of the drum, through a first predetermined angular range. The shutter member includes protrusions while the rotary drum includes recesses for receiving the protrusions, such that a meandering air flow passage is formed between the shutter member and the rotary drum. As such, friction between the rotary drum and the stationary shutter member is reduced, thereby reducing the power consumption of the suction system.Type: GrantFiled: August 25, 2017Date of Patent: August 21, 2018Assignee: OCÉ HOLDING B.V.Inventors: Antonius G. H. Albers, Johannes H. L. Smeyers, Albert M. Van Beek, Marcel J. H. M. Haenen, Wilhelmus H. J. Nellen

Patent number: 9573780Abstract: A sheet transport assembly is provided for transporting a sheet along a process unit configured for applying a process to the sheet. The sheet transport assembly includes: a conveying unit including a transport belt and a deflection element. The transport belt is configured for advancing the sheet in a transport direction along the process unit to the deflection element, the sheet being placed with a contact side on the belt and a process side towards the process unit. The deflection element is arranged in contact with the transport belt to deflect the transport belt downstream in the transport direction relative to the process unit. The sheet transport assembly further includes a separating unit for separating the sheet from the transport belt. The separating unit is connected to an air supply source.Type: GrantFiled: November 25, 2015Date of Patent: February 21, 2017Assignee: OCE-TECHNOLOGIES B.V.Inventors: Peter G. La Vos, Albert M.
