Application roller and process for their manufacture

The invention relates to an application swab for liquids Media, such as those used in printing technology for application of liquids such as varnish or the like. on surface sections of an object to be excluded from subsequent treatment, while the surface submissions to be supplied to the treatment should be borrowed uncovered. The subject of the invention also includes a method for manufacturing such an applicator roller

The currently usual leohnlk looks for this purpose the cutting of circumferential grooves of a given depth into the surface of the roller carrying the liquid, while the remaining "areas of the rolled surface are keep full diameter. There are therefore special patterns of liquids for each application

leading surface sections Id corresponding rollers elngefprmt. This technique is extremely complex and requires in particular a high Work required for each application ₉ wherein a reusability a machined in the manner mentioned V / Alze for a auderen Anwendungefall generally does not come into consideration. From this follows the need for extensive storage of different rolls. The effort is also increased because faulty machining of a roller makes it necessary to turn off the entire surface of the roller, since there is no possibility of correction.

In contrast, the object of the invention is to create an application roller for local media »which is simple in construction and economical to manufacture makes storage only necessary for certain roller components, which are then used to determine the liquid-carrying surface sections on a Roller surface can be arranged in any catfish can · The inventive solution to this problem In the case of a fine applicator roller, sioh mainly identifies a radially expandable tendon with at least one jacket element extending over the circumference of the tendon, furthermore a tensioning device acting on the tendon ^ by means of derefr at least one circumferential descendant of the tendon against the hlerduroh in its re / tofciYste llung beaüglioh des Tendon member fixed sheath element can be pressed on 1st.

The manufacturing process belonging to the subject matter of the invention is mainly characterized by following work steps:

a) a radially expandable expansion member with a substantially cylindrical circumferential surface is produced uhd with at least one radially substantially inextensible, annular and with respect to of the expansion member coaxially arranged jacket element occupied, which one for the application of liquid has provided outer surface;

b) the expansion member is expanded radially by tensioning and pressed with the inner surface of the dumbbell element;

c) the expansion member is in its tensioned position, locking and securing the position of the jacket element noted with respect to the expansion link.

Further features and advantages of the invention emerge from the following description of an exemplary embodiment with reference to the drawings. Herein shows:

The application roller shown as an example is in particular for the application of varnish or cover lacquer on sheet or plate-shaped materials such as Paper, cardboard, sheet metal or the like. Suitable for a fee, with the application in strelfen-shaped surface areas of a certain width. The overall designated 20 roller has a certain number of order-defining, universally usable elements on who are themselves extremely simply trained and can be kept available with little effort. For the respective application, these order-determining elements in a corresponding number selected and fixed on the roller body in the intended position, which calibrates an optimal Adaptability of the roller for different applications results in

In the exemplary embodiment shown, order-defining jacket elements 22 are provided, which are designed in the form of a belt and have a hinged end Have outer surface 23.

As a result of the elasticity of the elastic member, the Macitel elements are released again immediately after the release and can be moved into other positions on the elastic member . Here , the outer diameter of the expansion member again assumes its initial value.

The clamping device 25 comprises a core member 34 formed as a shaft with a conical outer surface 35, the shape of which is adapted to the longitudinal bore or the inner surface 30 of the expansion member 21. Sas core member 34 is from the in Flg. 4 is inserted into the longitudinal bore of the expansion member and is axially braced with the expansion member. Here, the core member has a twofold effect, namely on the one hand the radial support and on the other hand the radial oisdehnuag or pretensioning of the expansion member with the shell elements 22 «

The axial clamping of the core member 34 within of the expansion joint 21 takes place with the help of a screw connection, the one located on the tapered end of the core member Qevlndeabsohnitt 40 and a Druok nut 42 and a thrust washer 4I.

The production of the expansion member 21 and the ring-shaped and, in the example, band-shaped jacket » elements 22 takes place with predetermined dimensional tolerances * Of particular importance, however, is that the construction of the roller 20 according to the invention is comparative wide tolerance limits with regard to the dimensions of the

Overall, there is an advantageous possibility of mass production of all parts of the applicator roller according to the invention.

At both ends of the core member 34 are support means in the form of stub shafts 44 for the rotary bearing of the Roller provided · In the example design, these stub shafts are integral with the core member 34 Furthermore, drive means in the form of a toothed wheel 45 are located at the stronger end of the core link 34 intended for the rotary drive of the roller.

When the expansion member 21 is radially tensioned, annular circumferential surface sections of the expansion member become pressed with the inner surface of a ja & en jacket element, wherein the axially adjacent sections of the expansion member upset radially and also a lateral one Cause compression of the jacket elements. For this, the elasticity of the jacket elements is essential, since the Xanten of the jacket elements accordingly in the elastic jacket of the stretching member imprint. Overall, this not only results in a friction-locked, but also in Axialriohtung form-fitting locking de jacket elements, as shown in Flg. 3 illustrates let.

The ring-shaped casing elements 22 are produced from a substantially inextensible band of suitable width or from a tubular body by appropriate cutting. The width of the jacket elements depends on the intended width of the 71äohenabsohnltte to be charged with liquid. The cross-sectional structure of the shell members is illustrated in Figure 71g x 5.
