摘要： A method for cleaning a printing fluid off a surface of at least one rotatable component of a printing press includes selecting and executing one of a plurality of predefined cleaning operations in an automated way. The selection is made on the basis of a predefined mathematical model executed on a computer and, when the model is executed, a parameter corresponding to an amount of the printing fluid present on the surface is calculated. The improved cleaning method may be applied in all modes of operation of the printing press and in particular allows detergent, cleaning cloth, and/or water to be saved.

摘要： A vacuum wiper, comprising a housing, a connection port, multiple holes and a hole adjusting means; the housing contains a cavity; the connection port is disposed on the housing and is in communication with the cavity; the multiple holes are disposed on the housing in the length direction of the housing, such that the cavity of the vacuum wiper housing is able to be in fluid communication with the outside via the multiple holes. The vacuum wiper has a maximum vacuumizing length when all of the multiple holes are in communication with the outside. The hole adjusting means is configured to be capable of blocking one or more of the multiple holes in sequence from two ends in the length direction of arrangement of the multiple holes of the vacuum wiper, such that the vacuum wiper is able to adjust the vacuumizing length. The provision of the hole adjusting means enables the vacuum wiping apparatus to have an adjustable vacuumizing length, in order to match the wiping of stencils with different length specifications, thereby effectively increasing the vacuumizing efficiency of the vacuum wiping apparatus and reducing the production cost.

摘要： A printing device for printing substrates, such as circuit boards, wafers, or solar cells, has at least one movably mounted printing unit with a working surface on which the substrate to be printed can be placed. The printing unit is paired with a transport belt device, which has a supply roller with a transport belt wound thereon, a collection roller for winding up the transport belt, and two deflecting surfaces, in particular deflecting rollers, which are paired with the working surface. The transport belt is guided by the supply roller over one deflecting surface and onto the working surface in order to form a contact surface for the substrates, and by the working surface over the other deflecting surface to the collection roller. The deflecting surfaces can be moved together with the respective printing unit. The supply and collection rollers are held on the printing device in a stationary manner.

摘要： A system and method is disclosed for cleaning an anilox roll and/or ink chamber of a converter. The system includes: a water supply adapted to supply water through an automatically controllable water supply valve to wash anilox roll and/or ink chamber; a cleaning solution supply adapted to supply a cleaning solution through an automatically controllable cleaning solution supply valve to clean the anilox roll and/or ink chamber; and a programmable controller programmed to operate the automatically controllable valves so as to deliver a timed sequence of water and cleaning solution to the cleaning part upon the occurrence of a cleaning cycle initiation condition.

摘要： A stereoscopic pattern apparatus includes a base roller and a retrieving roller, a fine pattern hardening roller, an ink inserting roller and a convex pattern hardening roller. The base roller and the retrieving roller respectively provide and retrieve a base film. The fine pattern hardening roller is disposed between the base and retrieving rollers, and forms a lower hardening layer on the base film. A fine pattern is formed on the lower hardening layer. The ink inserting roller is disposed between the fine pattern hardening roller and the retrieving roller, and inserts an ink into the fine pattern. The convex pattern hardening roller is disposed between the ink inserting roller and the retrieving roller, and forms an upper hardening layer on the lower hardening layer. A convex lens is uniformly formed on the upper hardening layer.

摘要： There is described an installation (01; 02) for recycling wiping solution of one or more intaglio printing presses (10) comprising a flocculation tank (12) for inducing flocculation of ink constituents contained in waste solution coming from the one or more intaglio printing presses (10), a processing tank (14) for pre-treating the waste solution for subsequent filtering, and a filtering unit (15), preferably a filter press unit, for filtering the waste solution coming from the processing tank (14) and producing recycled solution at an output of the filtering unit (15), which recycled solution is recycled to produce fresh wiping solution for use by the one or more intaglio printing presses (10). According to one embodiment, the installation (01) further comprises a centrifugation unit (13) for separating the waste solution coming from the flocculation tank (12) by centrifugation into precipitate and centrifuged supernatant, which centrifuged supernatant is fed to the processing tank (14). According to a second embodiment, the installation (02) further comprises a decantation unit (13a) for separating the waste solution coming from the flocculation tank (12) by decantation into precipitate and decanted supernatant, which decanted supernatant is fed to the processing tank (14), and a centrifugation unit (13b) for further separating the precipitate produced by the decantation unit (13a) by centrifugation into further precipitate and centrifuged supernatant, which centrifuged supernatant is fed to the processing tank (14). There are also described corresponding processes for recycling wiping solution.
