A device for cleaning a cylinder of a machine for processing printing material includes a cleaning cloth pressable onto the cylinder for forming a contact zone. A first monitoring zone is monitorable with regard to a faulty position of the cleaning cloth, and is disposed downstream of the contact zone in a travel direction of the printing material. A second monitoring zone disposed upstream of the contact zone in the travel direction of the printing material is monitorable with regard to another faulty position of the cleaning cloth.

Device for cleaning a cylinder of a printing-material processing machine

A method of removing from a printing machine, with the aid of a traverse of the printing machine, a cleaning device assigned to a cylinder, which comprises, in a first method step, shifting the traverse out of a parallel position relative to the cylinder, wherein a side wall of the printing machine blocks a movement of the cleaning device, guided by the traverse, out of the printing machine, into an inclined position relative to the cylinder, the cleaning device guided by the traverse being movable past an outer contour of the side wall or through an opening formed in the side wall, and out of the printing machine, and, in a second method step, moving the cleaning device, guided by the traverse, in the longitudinal direction of the traverse and out of the printing machine; an assembly for performing the method; and a printing machine having at least one assembly for performing the method.

A device for washing outer cylindrical surfaces of a rotary printing machine is disclosed. The device uses a washing cloth which is unwound from a supply roll and, via a pressing-on rail, supplied to a take-up roll. The washing cloth is pressable by the pressing-on rail against the outer cylindrical surface to be washed. To simplify operation only the two washing-cloth rolls with the washing cloth are changed and the other components of the washup device remain inside the machine.

Device for selectively cleaning a plurality of cylinders of a sheet-fed printing press includes a washing device having equipment forming a cleaning surface, and a mutual pressure device for selectively bringing the cleaning surface into contact with one of the cylinders along a line of contact of the cleaning surface and the one cylinder extending parallel to a longitudinal axis of the one cylinder, and drive device for moving the cleaning surface so as to vary the position of the contact line with respect to the cleaning surface.

Device for selectively cleaning a plurality of cylinders

A combination of a winding shaft and a clamping device for a cardboard winding tube slid onto the winding shaft is provided, wherein the clamping device includes a clamping rod received in respective first and second end parts so that the end parts are braced axially opposite to one another by the clamping rod, a sleeve formed of rigid material mounted coaxially on the clamping rod, and at least one radially acting and elastically deformable annular clamping element for frictionally locking together the winding shaft and a winding tube slid onto the winding shaft, the clamping element being of annular shape and being disposed coaxially on the clamping rod between the first end part and the sleeve, a first bearing member mounted in a first side part of a housing having two side parts, a plug-in coupling having a device for connecting the first end part to the first bearing member, and a second bearing member mounted in a second side part of the housing for supporting the second end part.

A cleaning device for a printing press for cleaning a rotating outer cylindrical surface of a roller or cylinder by a cleaning-cloth web having a given width and edges extending perpendicularly to generating lines of the outer cylindrical surface includes a diaphragm subjectible to pressure at one side thereof by a pressurized fluid for pressing a section of the cleaning-cloth web against the outer cylindrical surface, the diaphragm being formed with a raised first surface region matching the given width of the cleaning-cloth web and being engageable with the cleaning-cloth web, the diaphragm having a surface with second surface regions facing towards the cleaning-cloth web, the second surface regions being offset by a step with respect to the first surface region.

Cleaning device for a printing press

A washing device formed as an insert unit on a printing machine for cleaning the outer cylindrical surface of rollers or cylinders includes a washcloth supply roll and a dirty-washcloth take-up roll for a washcloth, a device for saturating the washcloth with washing medium, a device for withdrawing the washcloth from the supply roll by winding the washing device on the take-up roll via an actuable pressure applicator, so that, during a washing operation, the pressure applicator presses the washcloth against a roller or cylinder, the take-up roll being connectible with a feeder device fixed to the machine, the washing device being automatically connectible with a roll-sensing device fixed to the machine when it is slid as an insert unit into position in the machine, an upwardly exposed washcloth section, in the slid-in position, being disposed upstream of a membrane member, as viewed in transport direction of the washcloth, the washcloth section being located beneath a washing-medium dispenser device fixed to the machine and extending along an elongated side of the washing device.

Washing device formed as an insert unit

A washing-medium dispensing device for a washing device of a printing machine which cleans the outer cylindrical surface of rollers or cylinders includes a distributor line formed with a plurality of dispensing apertures extending over the length of the washing device, as washing-medium supply vessel being under atmospheric pressure and connected to the distributor line for feeding washing medium thereto, and a slider device for controlling a dispensing release of the dispensing apertures simultaneously; and a washing device including the dispensing device.

Washing-medium dispenser and washing device

Washing device of a printing machine for cleaning the outer cylindrical surface of a roller or a cylinder, comprising a supply roll and a take-up roll for a cleaning cloth dampenable with washing medium, means for withdrawing the cleaning cloth from the supply roll by winding it on the take-up roll via an actuable pressure applicator so that, during a washing operation, the pressure applicator, presses the cleaning cloth against a roller or cylinder, the pressure applicator having an elastic membrane member which is sealed with respect to a spacer, and means for forming a compressed-air cushion between the membrane member and the spacer, a holding member for receiving the spacer therein in a manner like that of a sliding block, the membrane member having marginal regions thereof engaging behind guiding projections of the holding member, the spacer being biased towards the guiding projections for sealingly clamping the marginal regions of the membrane therebetween.
