LOW-VOLUME FLEXOGRAPHIC INKING SYSTEM

An inking system for use in transferring ink to a flexographic printing plate in a flexographic printing system includes an anilox member having an ink transfer zone located between first and second recessed bearing contact zones. A radius of the recessed bearing contact zones is less than a radius of the ink transfer zone by at least 0.100 inches. An ink tray includes a floor and first and second end walls. Bearings are mounted outside of the end walls which engage with the first and second bearing contact zones, respectively, thereby positioning the ink tray assembly in a specified position relative to the anilox member. Upper edges of the end walls extend into the recessed bearing contact zones.

Doctor blade holder and adjustment mechanism
10661555 · 2020-05-26 · ·

A doctor blade holder and adjustment mechanism that may be utilized with a flexographic printing system. The doctor blade holder and adjustment mechanism may utilize a constant displacement of the doctor blade against an anilox roller, rather than a constant force, to reduce ink build up on the back side of the doctor blade, and subsequently, intermittent dropping of the accumulated ink onto the post-shearing side of the anilox roller (spitting). The doctor blade holder and adjustment mechanism may provide adjustability of a combination of doctor blade pressure, angle and displacement.

Method and device for monitoring production of fluid film
10661299 · 2020-05-26 ·

A method for monitoring production of a fluid film, including: activating a dispenser to deliver appropriate material from a storage duct to a metering system for even distribution of a fluid film; allowing the fluid film to pass a sample retrieving roller; measuring the fluid film on the sample retrieving roller using a data reading device to obtain film thickness data; transmitting the data to an analyzer to examine the data against a predetermined reference value; transmitting a comparison result in real time by the analyzer to a production equipment controlling console; controlling the storage duct to dispense material through the material metering system and adjusting the film thickness; repeating the above steps to make a film thickness within the reference range; and maintaining the thickness at the narrowest tolerance deviation, and continuously delivering the film onto a substrate for production.

Ink Fountain Device

An ink fountain device having a base; a plate; an advancing and retracting mechanism for advancing and retracting the plate along an advancing and retracting direction; and a thin sheet arranged on the base which has plural holes accommodating balls and is thinner in thickness than a diameter of the balls. The plate is arranged over the thin sheet and supported by the balls.

METERING ROLLER FOR AN INK STATION ASSEMBLY OF A DECORATOR AND A METHOD OF DECORATING A CONTAINER WITH THE DECORATOR
20200147954 · 2020-05-14 · ·

An apparatus and methods of decorating exterior surfaces of metallic containers are provided. More specifically, the present disclosure provides a novel metering roller for an inking assembly of a decorator. An adjustment mechanism is operable to move the metering roller to a first ink transfer position during a decoration run. In the first ink transfer position, the metering roller receives ink from an ink roller without contacting the ink roller. In one embodiment, during the production run, the metering roller is in contact with and transfers ink to a transfer roller. When the decoration run stops, the adjustment mechanism can move the metering roller to a second dwell position such that the metering roller does not receive ink from the ink roller.

MAIN BODY OF A DOCTOR BLADE CHAMBER, DOCTOR BLADE CHAMBER THEREOF AND METHODS OF MANUFACTURING SAME

A main body of doctor blade chambers including a first portion configured to hold a first doctor blade, a second portion configured to hold a second doctor blade, a third portion connecting the first portion and the second portion, a cavity intended to receive ink and defined at least by the first portion, the second portion and the third portion, characterized in that the main body is a single closed hollow profile extending along a longitudinal main axis X-X, the main body being made of pultruded composite material.

Apparatus for flexographic printing and an inlet module

The present disclosure relates to an apparatus for flexographic printing of a web of packaging material with printing ink and an inlet module for a flexographic printing apparatus. The apparatus may include an ink pan or chamber, and an anilox roll rotary at least partly inside the ink chamber for picking up and transferring printing ink from the ink chamber to an impression cylinder which is rotary in transfer contact with the anilox roll. The ink chamber may be elongated and extend axially along the anilox roll, the ink chamber having a first axial end and a second axial end opposite the first axial end. The apparatus may further include a first printing ink inlet arranged at the first axial end and a second printing ink inlet arranged at the second axial end.

Liquid transfer apparatus

A liquid transfer apparatus includes: rollers configured to transfer supplied liquid to a blanket cylinder; a roller holding device configured to detachably hold the rollers and perform a rotating operation to move any one of the rollers to a predetermined position facing the blanket cylinder; and a contact-separation unit configured to bring the roller held by the roller holding device and disposed at the predetermined position into and out of contact with the blanket cylinder.

DEVICE FOR COATING PANELS, PRINTING PRESS, AND METHOD FOR COATING PANELS
20200122454 · 2020-04-23 ·

A device coats one or more panels, printed by a coating means, which applies particularly a varnish or a primer. The device utilizes a forme roller which can be brought into rolling contact with the print stock to be coated, in the region of a contact zone, in order to coat the print stock on a side of the print stock facing the forme roller, and also utilizes a feed device supplying the forme roller with coating medium, which interacts, in the region of at least one contact zone on the circumference of the forme roller, with the forme roller, in order to continuously apply the coating medium, which is to be applied to the print stock, to a shell surface of the forme roller to an application width. A removal device, having removal elements, is associated with the forme roller and by the use of which removal device, the coating medium previously applied continuously to the shell surface, over the application width via the feed device, can be removed from the shell surface, before a downstream delivery to the print stock, which removal is, in one or in a plurality of partial width sections, relative to the application width, synchronized to one of a machine and a print stock phase position for one of defined and definable phase lengths. A method for coating and a printing press having a coating device are also disclosed.
