Publication number: 20190337752Abstract: A folder for a printing press includes a cutting cylinder assembly having at least two knife and anvil cylinder sets positioned near the cutting region of a folder. The cutting cylinder assembly slides or actuates one of the knife and anvil cylinder sets into a cutting position for a desired cut length. The web passes between the knife and anvil cylinder set and is cut. When the cut length needs to be changed, the assembly is relocated to such a position that a second or further set of knife and anvil cylinders is aligned with the web.Type: ApplicationFiled: July 19, 2019Publication date: November 7, 2019Inventors: Gerald Roger Douillard, JOHN JAMES SPOSATO, Jeffrey S.

Patent number: 6705219Abstract: The web-fed rotary offset printing machine utilizes a blanket belt onto which two or more colors are offset and which prints the two or more colors at once onto a material web. The blanket belt travels about guide rollers which have a lesser mass and/or a lesser diameter than the form cylinders which offset the colors onto the blanket belt. If several impression nips—blanket to web nips—are formed along the travel path of the material web, they are located so close to one another that fan out register errors cannot occur.Type: GrantFiled: September 6, 2001Date of Patent: March 16, 2004Assignee: Heidelberger Druckmaschinen AGInventors: Gerald Roger Douillard, Eric Michael Lapine, Michael Robert Lemelin

Patent number: 6615726Abstract: A method for identifying a lateral position of a vibrator roll geared to a plate cylinder in a printing press includes the steps of sensing a reference lateral position of a vibrator roll, setting a counter to a setting corresponding to the reference lateral position of the vibrator roll and rotating a plate cylinder. The lateral position of the vibrator roll changes as a result of the rotating of the plate cylinder and the counter changes as a function of the rotating of the plate cylinder.Type: GrantFiled: September 6, 2001Date of Patent: September 9, 2003Assignee: Heidelberger Druckmaschinen AGInventors: Gerald Roger Douillard, Mark Bernard Dumais, Michael Thomas Woroniak, John Allan Manley, John Antonios Panteleos, Charles Francis Svenson

Patent number: 6526888Abstract: A method for reducing vibrations in a printing press, the printing press having a first plate cylinder independently registrable from a second print cylinder. The method includes the steps of determining a lateral position of the first vibrator, roll with respect to the second vibrator roll and rotating the first plate cylinder with respect to the second plate cylinder so as to change the lateral position of the first vibrator roll with respect to the second vibrator roll. A printing press has a controller receiving an input from at least one sensor, the controller rotating the first plate cylinder with respect to the second plate cylinder so as to alter a phase between the first vibrator roll and the second vibrator roll as a function of the input.Type: GrantFiled: December 1, 2000Date of Patent: March 4, 2003Assignee: Heidelberger Druckmaschinen AGInventors: Gerald Roger Douillard, Mark Bernard Dumais, Michael Thomas Woroniak

Patent number: 6308621Abstract: The bearing lubrication system for a cylinder in a printing machine pumps oil from the driving gear side to the roller bearing. The gear side has a gear box and an oil sump with a supply of lubricating oil. An oil loop connects the bearing housing with the gear box fluidically via dry quick disconnects. The dry disconnects allow quick removal of the printing machine cylinder for maintenance or for print job retrofitting. As the printing machine cylinder rotates (it is driven from the gear box), oil is pumped from the gear box into the bearing housing. The bearing is thus lubricated and cooled. The oil is discharged from the bearing housing and returned to the gear box sump.Type: GrantFiled: June 14, 1999Date of Patent: October 30, 2001Assignee: Heidelberger Druckmaschinen AGInventors: Gerald Roger Douillard, Eric Michael Lapine, Michael Robert Lemlin
