ABSTRACT:
A window envelope modifier can be assembled with a document which, when prepared for mailing, may be shorter than the inside length of a window envelope or narrower than the inside height of the envelope. The modifier prevents shifting of the document within the envelope during handling and mailing to an extent which might prevent the usual recipient's address on the document from being easily seen through the envelope window.
The modifier has a body portion with opposite ends and a transverse strip of contact adhesive spaced between such ends and closer to one end than to the other. A premarked or prescored fold line is located between the adhesive strip and the other opposite end. A removable protective strip may cover the adhesive strip prior to use. The modifier is capable of use in either flat or preferably folded form and may be provided as separate individual sheets or as severable portions of a continuous supply roll.
