## Title
Label folding apparatus and methods for its use

## Abstract

A label folding apparatus and methods for its use are disclosed. Such a label folding apparatus comprises a label folding assembly and a label holding assembly, and may be used to fold a foldable label placed onto the label holding assembly.

## Background
BACKGROUND
Labels are commonly used to secure printed indicia to packages to indicate shipping or other information. In the instance of a shipping use, a separate packing list may be enclosed within a package shipped to the customer containing a purchased item.
There is significant demand for a labeling method that allows automatic printing and application of a lower label and an upper label to a surface. For example, there is significant demand for a labeling method that allows automatic printing and application of a packing list and shipping label to the surface of a sealed carton. Because the carton is sealed prior to packing list generation, it is not efficient to open it to insert a packing list. High volume shipping of such packages requires rapid attachment of a packing list and a shipping label to the package. It is preferred to conceal the information of the packing list until the final recipient receives the shipped package.
Complicated methods have been implemented for application of a lower label and an upper label to a surface. For example, where a packing list and shipping label are to be applied to the surface of a sealed carton, complicated methods have been implemented in which a packing list is applied and adhered atop a carton, using a first roll of labels (packing list labels) and a first label applicator. After the packing list label is applied, an address label is applied and adhered atop the packing list label, to conceal the packing list information, using a second roll of labels (address labels) and a second label applicator. Such methods have many shortcomings. For example, precise timing between the packing list application and the shipping label application is required to properly align the two labels, and to avoid mismatches between the packing list and the shipping label (e.g., where the packing list contains information about goods to be shipped to a first customer and the shipping label contains the address of a different customer. In addition, because two printers and two label applicators, along with related hardware and software, are required to apply a packing list and shipping label in sequence, such methods require significant floor space and investment. For the foregoing reasons, it is desired to provide labeling methods that allows automatic printing and application of a lower label and an upper label to a surface while avoiding the many shortcomings of existing labeling methods.
For the foregoing reasons, it is desired to provide labeling methods that allows automatic printing and application of a packing list label and shipping label to the surface of a sealed carton while avoiding the many shortcomings of existing labeling methods.

In the embodiment shown in FIG. 12, slide assembly 60 has traveled from the first position shown in FIGS. 1-3 to the second position shown in FIGS. 4-6. When slide assembly 60 travels from the first position to the second position, label deflector 68 engages foldable portion 104 of label 100, thereby displacing foldable portion 104 of label 100 from its planar alignment with covering portion 102 of label 100. In an embodiment of the present disclosure where label deflector 68 comprises a curved label deflector surface such as curved label deflector surface 70, label deflector 68 progressively engages foldable portion 104 of label 100 as slide assembly 60 travels from the first position to the second position, thereby reducing the risk that label 100 will be torn as label deflector 68 engages foldable portion 104 of label 100. In an embodiment of the present disclosure where label deflector 68 is affixed to first surface 61 of slide apparatus 60 at an angle to an axis of guide rails 50, label deflector 68 progressively engages foldable portion 104 of label 100 as slide assembly 60 travels from the first position to the second position, thereby reducing the risk that label 100 will be torn as label deflector 68 engages foldable portion 104 of label 100. In at least one embodiment of label 100, there may be one or more lines of weakness between covering portion 102 and foldable portion 104 so that displacement of foldable portion 104 by label deflector 68 is facilitated.
FIGS. 13-14 show label folding apparatus 10 with label 100 dispensed thereon according to at least embodiment of the present disclosure. In the embodiment shown in FIGS. 13-14, member 64 is extended from sheath 62. Roller 66 thereby contacts foldable portion 104 of label 100, folding foldable portion 104 on label 100 against covering portion 102 of label 100. The adhesive backing on a least a part of covering portion 102 of label 100 and/or foldable portion 104 of label 100 causes foldable portion 104 to be adhered against covering portion 102. In at least one embodiment of the present disclosure, a label folding device (such as, for example, a sheath, member, and roller device like sheath 62, member 64, and roller 66) is not affixed to a moveable carriage such as, for example, slide assembly 60. In such an embodiment, such a label folding device is in a fixed position in alignment with label pad assembly 20. In this fixed position, such a label folding device is aligned with the eventual position of a label that is dispensed onto label pad assembly 20. After a label is dispensed onto such a label pad assembly and portion of such a label has been displaced by a label deflector, such a label folding device then is actuated, thereby folding the label.
FIGS. 15-16 show label folding apparatus 10 according to at least one embodiment of the present disclosure with label 100 dispensed thereon. In the embodiment shown in FIGS. 15-16, member 64 is retracted into sheath 62, and roller 66 is brought out of engagement with foldable portion 104.
FIGS. 17-18 show label folding apparatus 10 according to at least one embodiment of the present disclosure with label 100 dispensed thereon. In the embodiment shown in FIGS. 17-18, slide assembly 60 is returned to the first position shown in FIGS. 1-3. Label 100 then may be applied to a substrate, such as the surface of a container or the surface of a package. In at least one embodiment, label 100 may be removed from label pad surface 202 manually and manually applied to such a surface. In at least one embodiment, label pad assembly 20 comprises a label applicator mechanism. In such an embodiment, label pad assembly 20 with label 100 attached thereto may be moved into alignment with such a surface so that the exposed adhesive on label 100 will be brought into contact with such a surface.
