DESCRIPTION:
BRIEF SUMMARY
This invention relates to a method and apparatus for making labels, particularly the so-called booklet-type labels in which there is a releasable outer label sheet and one or more printed inner label sheets forming a booklet.
Previously proposed apparatus for producing labels, particularly booklet-type labels has been subject to significant disadvantages, particularly with respect to their efficiency of operation and the complexity of the operations which the user is required to perform. For instance, there are disclosed in the following specifications, namely:
GB 2127378A; GB 2159118A; GB 2171386A; GB 2179020A; EP 0 154 057A; EP 0 161 914A; EP 0 192 444A; pre-printed webs and label components. However, the operation of such a machine necessitates the provision of pre-printed and assembled label components as a separate operation, and as a result the label manufacturing process becomes a multi-stage operation involving several sets of apparatus, transfer of product components between these and all these stages being attended by consequential efficiency penalties.
Printing apparatus exists for pre-printing individual components of multi-ply labels, one at a time. Such apparatus tends to be one sided and large and expensive and to require simple multiplication of the apparatus size in order to multiply colours and to print more than one web.
We have thus identified a considerable requirement for a method and apparatus for printing booklet-type labels offering one or more advantages in relation to matters discussed above, or generally.
According to the invention there is provided a method and apparatus for label manufacture as defined in the accompanying claims.
In an embodiment described below there is provided a label making press capable of printing and processing one, two or more webs of unprinted base label material. The press can continuously fold the material and can optionally trim it to sever the internal label sheets produced by the folding operation. In this way, at least one of the webs of label material produces at least two fold-joined or separated-by-trimming face-to-face label sheets in the finished label.
In the embodiments, perforation lines or bands of peelable adhesive may be provided to enable the various label portions to be separated from each other, or from an innermost label portion adhering to the product as a permanent product designation thereof, according to the user's requirements.
Embodiments of the invention will now be described by way of example with reference to the accompanying drawings in which:
FIG. 1 shows, somewhat diagrammatically, a first embodiment of a label produced by the method of the invention;
FIG. 2 shows, diagrammatically, an exploded side elevation view of the label of FIG. 1;
FIG. 3 shows a side elevation view of apparatus for manufacturing the labels of FIGS. 1 and 2;
FIGS. 4, 5 and 6 show, diagrammatically, three further label constructions which can be produced by the apparatus of FIG. 3.
As shown in FIGS. 1 and 2, a label 10 comprises an outer label member 12, a primary inner label member 14, and three secondary inner label members 16, 18 and 20. Label member 14 is coated with adhesive 22 across the full width of its lower surface and serves to secure the entire label assembly 10 to a product, not shown, and to identify same after removal of the remaining portions of the label during use as described below. Before application to the product the adhesive 22 is masked by a sheet of peelable release material, not shown.
Outer label member 12 is secured to inner label member 14 by two edge bands of adhesive 24 and 26. These bands releasably secure label member 12 to label member 14 whereby the former can be peeled away from the latter in use, as will be explained.
Sandwiched between the outer and inner label members are three secondary inner label members 16, 18 and 20 which are secured at their left hand edges (as seen in FIG. 2) by the adhesive band 24 on outer label member 12. Only the uppermost inner label member 16 actually contacts adhesive band 24 ov
