Abstract

In a preferred method for affixing a discrete paper label to the mailer, a discrete paper label is suctioned onto the rotatable platen at a first predetermined position relative to the circumferential perimeter of the platen. As the rotatable platen rotates, adhesive is applied to a predetermined exposed portion of the paper label at a second predetermined position relative to the circumferential perimeter. Finally, at a third predetermined position relative to the circumferential perimeter, the paper label is blown off the rotatable platen and onto an adjacent continuously advancing web comprising multi-ply mailer forms each having a plurality of sheets in superimposed relationship. The paper label is thus affixed to a multi-ply mailed form at a predetermined location. Preferably, the rotatable platen receives a new paper label at the first predetermined position as the adhesive is applied to the label previously received on the platen.

Claims

1. A method of affixing paper labels to multi-ply mailers using a rotatable platen having a circumferential perimeter, comprising the steps of:

(a) suctioning a discrete paper label onto the rotatable platen at a first predetermined position relative to the circumferential perimeter, the paper label comprising an admixture of electron-acceptor material and chromagen-containing microscopic pressure-rupturable capsules;

(b) applying adhesive to a predetermined exposed portion of the paper label at a second predetermined position relative to the circumferential perimeter;

(c) at a third predetermined position relative to the circumferential perimeter, blowing the paper label off the rotatable platen and onto an adjacent continuously advancing web comprising multi-ply mailer forms each having a plurality of sheets in superimposed relationship, wherein the paper label is affixed to a multi-ply mailer form at a predetermined location, wherein the predetermined exposed portion of the paper label consists of peripheral edge portions of the label, with non-peripheral edge portions of the label being substantially free of adhesive to avoid activation of the pressure-rupturable capsules during transfer of the label to the mailer; and

(d) heating the continuously advancing web following transfer of the paper label to the mailer to thereby dry the adhesive prior to any chemical reaction between the adhesive and the chemicals in the label.

2. The method of affixing paper labels to multi-ply mailers as described in claim 1 further including the step of:

(d) repeating steps (a)-(c) as the web of multi-ply mailer forms is continuously advanced.

3. The method of affixing paper labels to multi-ply mailers as described in claim 1 further comprising the step of:

(d) repeating step (a) for a new paper label during step (b); and

(e) repeating step (b) for the new paper label during step (c).
