Labelling apparatus and method for correcting visual adhesive defects
First Claim
1. A method of correcting defects in a label resulting from a non-uniform application of adhesive to a surface of the label prior to applying the label to a container, said method including the following steps:
- a. applying an adhesive to a surface of a label in a non-uniform manner to cause regions of said surface to be substantially devoid of said adhesive, and after applying said adhesive;
b. applying a fluid in said regions to substantially fill said regions.

Abstract
A method of correcting defects in a label resulting from a non-uniform application of adhesive to a surface of the label prior to applying the label to a container includes the steps of applying an adhesive to a surface of a label in a non-uniform manner to cause sections of the surface to be substantially devoid of the adhesive, and after applying the adhesive, applying a fluid in these latter sections to substantially fill them. The fluid is applied either onto the container in regions that are aligned with the label sections that are devoid of adhesive, or is applied directly onto the adhesive-free label sections. An apparatus for carrying out the above method also forms a part of the present invention.

24. An apparatus for continuously applying plastic labels to containers, said apparatus including:
-
A rotatable applicator roll for receiving an adhesive on the outer surface thereof;
A rotating transfer member including a plurality of transfer pads carried thereon, said transfer member being located to rotate the transfer pads in close proximity to the outer surface of the applicator roll, whereby adhesive from the roll is transferred to an outer surface of each of said pads;
A dispensing magazine for retaining a plurality of individual labels in a stack, with the lowermost label in the stack being located in a downstream path of travel of the transfer pads after each of said transfer pads has engaged the outer surface of the applicator roll to receive adhesive thereon, each of said pads, with the adhesive thereon, being rotated into close proximity with the lower surface of the lowermost label in the magazine for selectively applying the adhesive to the lower surface of said lowermost label in the stack in a manner that leaves at least one region on said lower surface substantially free of adhesive and for removing said lowermost label from the stack through surface adhesion to releasably secure said lowermost label to each of said transfer pads;
A second rotating transfer member for receiving said labels from the transfer pads prior to said labels being applied to a container; and
Means for applying a fluid in said at least one region to substantially fill said at least one region. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
