ABSTRACT:
The invention relates to an apparatus for the application or placement of a self-adhesive label onto a disk-shaped object, particularly a compact disk, in accordance with the introductory clause of claim
1
. The invention further relates to a label adaptedly structured commensurate with the apparatus, in accordance with the introductory clause of claim 10. Furthermore, the invention relates to a method of operating the apparatus according to the invention.
From the published PCT-International Application No. WO 96/05057 there is known an apparatus for best possible centric placement of a self-adhesive label onto a compact disk. A centered adhesive application of a label upon a compact disk, also known as a CD, is extremely important for technical reasons. A CD rotates during the reading process at a very high reading rate. If the CD is unbalanced, the thereby caused eccentrically acting forces are imparted to the reading device, particularly to the mechanical parts and the reading head, which results in premature wear or even damage or breakage of the reader. Therefore, the adhesive label must be applied or affixed onto the compact disk in an exact as ever possible centric position. The known apparatus of the aforementioned-prior art has the disadvantage in that it consists of several single components which have to be manually assembled and guided in a determinate consecutive renders difficult an exact centering of the label with respect to the CD and, on the other hand, this reveals problems while holding the individual components, because the sticky surface of the positioned adhesive label renders practically impossible the detachment of fingers without shifting the label off-center. A further disadvantage is seen in the fact that, subsequent to detaching the carrier foil and during the placement on the device, the label arches, bends up in dead center and is thus not arranged to be layed totally flat. Furthermore, it is conceivable that the manually guided CD is placed in a position slightly canted relative to the label, so that, for instance, air bubbles locked between the CD and the label can build up, or the label is affixed eccentrically relative to the CD. Furthermore, there is a clearance or play:
between the positioning hole and the inner circle of the adhesive label;
between the positioning hole and the cylindric guide; and
between the inner circle of the compact disk and the diameter of the cylindrical extension.
It is an object of the present invention to provide a new and improved apparatus for applying a self-adhesive label onto a disk-shaped object, particularly a compact disk, which apparatus renders possible a simple, centered and reliably reproducible placement of the adhesive label.
This object of the invention is implemented by means of an apparatus characterized by the features according to claim

A further object of the present invention is to provide a new and improved adhesive label for a compact disk, which label is adapted to the apparatus according to the invention and renders possible a simple and dependable application thereof onto the compact disk.
This object is implemented by means of an inscribable or printable compound label comprising the

Furthermore, the object of the invention is solved by a method of applying self-adhesive labels, said method having the characteristics defined in claim
18
.
The apparatus according to the invention for especially centric placement of a self-adhesive label onto a disk-shaped object, particularly a compact disk, comprises a first housing part with a locating device for the adhesive label as well as a second housing part with a locating device for the disk-shaped object, whereby the housing parts are movably connected with each other, particularly in swivelling or translational manner, and conveyable from an open position into a closed position in such a manner that, in the closed position, the locating devices are placed in a position arranged to face one another, and that in said closed position at least one of the locating devices is movably arranged in the respective housing part to travel in the direction toward the respective opposite locating device, in order to bring the disk-shaped- object into contact with the adhesive label.
An advantage of the apparatus according to the invention is seen in that, in the open position, the compact disk is readily and conveniently insertable in a position determined by the second housing part, and in that the self-adhesive label together with the carrier foil and/or grip tabs thereof is readily and conveniently insertable and positionable in a position determined by the first housing part. Subsequent to the insertion into the first housing part, the carrier foil of the adhesive label is detached or peeled off, whereby the label is securely located by said first housing part, so that there is hardly any hazard or risk that the fingers of the operator can come into contact with the bare sticky surface of the adhesive label. By way of example, the two-housing parts are connected with each other to swivel about a common swivel axis, so that in a simple manner the housing parts can be foldingly brought into a closed position, after which the compact disk and the adhesive label are arranged and aligned opposite one another. In this position there is exerted, particularly upon the center of the second housing part or rather upon a control button arranged thereat, a light force directed toward the first housing part, so that the two housing parts or rather the two locating devices draw closer to one another and the compact disk thereby comes to lie on the adhesive label, the latter thus being affixed.
In a further advantageous embodiment of the apparatus according to the invention, the adhesive label and the compact disk in the closed position are arranged to be accurately mutually centered. During the closing travel into the closed position, the mutual centering takes place automatically, so that the adhesive label and the compact disk in their closed position are arranged to be superimposedly centered and now only have to be moved for mutual contact by means of a slight pressing movement. Self-adhesive labels can be thus exactly centrically affixed to compact disks or other disk-shaped objects.
The mutual or interdependent centering of the two housing parts or rather of the two locating devices has the further advantage in that the apparatus according to the invention renders possible exact centering of the adhesive label relative to the compact disk even then, when the component parts, for instance, on the basis of process or work tolerances, are shaped slightly differently. Mutual centering thus also exercises a tolerance-compensation function. An advantage is obvious in that the component parts with low tolerance requirements can be cost-effectively fabricated. By virtue of the relatively low tolerance requirements, the apparatus according to the invention consisting of several component parts is also relatively simple and economical to assemble.
The two housing parts can be brought by means of translational motion and/or rotatory motion into a position for mutually centering the label and the disk-shaped object. In a preferred exemplary embodiment the two housing parts are mounted to be set in motion about a common swivel axis.
In an advantageous embodiment the first housing part comprises a flat supporting surface for a label or rather for a compound label, so that the latter in a first step is layed upon the flat supporting surface and thereafter the carrier foil and/or the grip tabs are peeled off, so th
