Assignee:

Heidelberger Druckmaschinen AG - Heidelberg

International Classification:

B41F 1300

US Classification:

101480, 101494

Abstract:

A method and an apparatus are provided for absorbing lateral sideframe vibration in printing units. A member is connected between two sideframes of a printing unit. According to one embodiment, the member is a rod and a mass slides on the rod. The mass is biased between two springs and a unit frame tie surrounds the rod. According to another embodiment, collars are disposed on the rod for adjusting the preload of the springs and additional masses may be placed on the mass sliding on the rod. A further embodiment includes a unit frame tie acting as the member and a rod connected to the unit frame tie. A mass is movable on the rod.

International Classification:

B41F 3100

US Classification:

101484, 101220, 1013503, 101DIG 38

Abstract:

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.

Abstract:

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.

Abstract:

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 nipsâblanket to web nipsâare formed along the travel path of the material web, they are located so close to one another that fan out register errors cannot occur.

US Classification:

493441, 493405, 493416, 493423, 493435, 493450

Abstract:

An apparatus for transporting folded signatures is provided which includes a first roller and a second roller forming a first nip with the first roller. The first and second rollers each have a compressible outer layer, and are rotatable about respective axes. Preferably, the compressible outer later comprises a microcellular foam. The apparatus also includes a plurality of first transport tapes passing through the first nip and a plurality of second transport tapes passing through the first nip. The plurality of second transport tapes are wrapped at least partially around the second roller so that a signature transported between the first and second transport tapes between the first nip undergoes a change in transport direction as it is transported at least partially around the second roller. Preferably, the signatures enter the first nip perpendicular to a plane passing through the axes of the first and second rollers.

US Classification:

271109, 271225

Abstract:

An apparatus for transporting signatures is provided which includes a moving transport surface for transporting signatures; a pair of eccentric guide rollers, rotatable about respective axes, the pair of guide rollers positioned opposite one another to receive signatures therebetween from the moving transport surface; and a diverter positioned downstream of the guide rollers. The diverter is movable between a first position to divert signatures received from the guide rollers to a first downstream moving transport surface and a second position to divert signatures received from the guide rollers to a second downstream moving transport surface.
