In order to make handling easier, an apparatus for pulling a sleeve onto and off a printing-press cylinder has a head piece () having a positioning device () for defining the position of the head piece () with respect to the cylinder (), a connecting device () for fixing the head piece () to the cylinder (), and a centering device () for defining the position of the sleeve () with respect to the head piece () and a deposition bar () for the sleeve (), which deposition bar () is attached to the head piece ().

Apparatus for pulling a sleeve on and off

The invention provides an apparatus for the mounting and/or demounting of at least two printing sleeves outside a printing unit of a printing machine. The printing sleeves include an outer printing sleeve forming a printing surface and an inner printing sleeve providing diameter compensation between the outer printing sleeve and an impression cylinder of the printing machine. The apparatus having a reception device onto which an inner printing sleeve can be pushed for mounting the two printing sleeves. The apparatus having at least one compressed-air device for facilitating the fixing of the inner printing sleeve on the reception device and for conducting compressed air through orifices assigned to the inner printing sleeve in order thereby to make it possible for an outer printing sleeve to be pushed more easily onto the inner printing sleeve.

Apparatus and method for changing printing sleeves on a printing machine

In an apparatus for pulling off sleeves () which are applied to cylinders () of a printing press, a force for pulling off the sleeve is applied in a gentle manner, in that a retaining rod (), having a retaining head () which can be fixed to the sleeve (), and a hammer weight which can be moved along the rod () between stops () are provided.

Apparatus and method for pulling off sleeves

In an apparatus for producing a printing image on a printing medium held by a cylinder () by a laser, the laser writing head () of which is positioned on a crossmember () so as to be displaceable parallel to the axis of the cylinder (), a space-saving functionally reliable embodiment is attained by the fact that a protective switch () which detects the presence of a cylinder () is provided fixedly on the crossmember () and the crossmember () bears switching strips () which expose a laser writing head displacement region (b) between them having the width of the printing image () and interact with a further protective switch () attached to the laser writing head () for switching off the laser when it is situated outside the laser writing head displacement region (b).

Apparatus for producing a printing image by means of a laser

A web-fed printing machine is provided. The printing machine includes a plurality of printing units. A first work station precedes the printing units. A second work station follows the printing units. At least one lifting device is assigned to the printing units for transporting printing unit modules. The lifting device is movably mounted on a top side of the printing units.

Printing machine

An apparatus for transporting printing sleeves is provided. The transport apparatus includes a housing with a bottom wall, a plurality of side walls, and at least one cover. A plurality of reception devices are mounted in the housing. Each reception device receives a printing sleeve in a vertically oriented transport position with a longitudinal mid-axes of the respective printing sleeve extending vertically. Each reception device is movable out of the housing into an outside position when the at least one cover of the housing is open. Each reception device is pivotable in the outside position such that the corresponding printing sleeve can be moved out of the vertical transport position into a horizontal extraction or insertion position.

Apparatus for the transportation of printing sleeves

A rotary printing machine having a plurality of printing-unit cylinders mounted one above another on a side wall, their axes lying in a plane inclined with respect to the plane of the printing-material web. An image-setting device is arranged wholly within the range of the obtuse angle which is formed by the plane of inclination of the cylinders and the plane of the printing-material web.

Printing machine with image-setting device for a rotary printing machine

Apparatus for producing printing plates in particular a blank sleeve-like printing plate, includes a cylinder carrier for receiving a printing plate, the cylinder carrier being held in cantilever fashion at one end in a frame in a mounting and is driven by a motor, it being possible for the printing plate to be pushed onto the carrier cylinder at an opposite side of the latter which faces away from the mounting and is, therefore, more accessible for making printing plate exchange. An image-setting device is moved along the carrier cylinder.

Apparatus for producing printing plates

A complete cleaning system for printing cylinders within a rotary printing press, by which a reactive erasing of ink-bearing layers, including the removal of filling materials from a gravure printing form, and a cleaning of ink from all form and transfer cylinders are possible during the printing process or during printing pauses. At least one erasing device is provided which emits a jet of water under pressure that can be directed against the corresponding outer surface of each desired cylinder so that, on the one hand, all traces of ink can be removed and, on the other hand, a reactive erasing of ink-conducting layers including filling materials from a gravure printing-form cylinder is possible.
