Description

ENVELOPE FILLING PROCESS
TECHNICAL FIELD OF THE INVENTION
The present invention relates to methods of automating mail processing.
BACKGROUND ART
The use of machines that need little or no human control can largely increase the speed with which letters are folded, loaded in envelopes and sorted before delivery. This is particularly so when a large volume of letters of similar or identical forms need to be processed. Automation, including the steps of mechanical insertion and sorting, can also minimise the occurrence of mis-filling of letters and sorting problems. The cost of processing letters can be largely reduced as the process is no longer labour-intensive.
Automised letter processing services have been widely adopted by businesses where large volumes of correspondence such as invoices or bills are processed and sent out to customers frequently. In the course of automatic mechanical processing, stamped envelopes are guided and conveyed by pinch rollers, guide rails or the like which abut and grip both sides of the upper portion of conventional standard-sized envelopes, adjoining the flap. Rollers or belts, which are affixed to guiding rails, are utilized as a primary conveying utility throughout the known processing or sorting lines.
However problems can arise when re-usable envelopes are being processed by the existing processing rollers which are commonly set at a certain position in a processing or sorting line. Re-usable envelopes, such as those disclosed in NZ502903, typically have a relatively broad sealing flap in which a tearable strip with a protruding end(s) is provided. The larger flap adds to the overall thickness of the envelope and can cause jams to occur during sorting since the flap extends into the area of the envelope that is contacted by the sorting machinery during the sorting process. Also, the protruding ends of the tearable strip are commonly not flush with the back of an envelope, in that they can be grasped and the tearable strip can be pulled by the receiver of the envelope. When mail is processed mechanically, gripping rollers or other machinery that sorts the envelopes normally contacts the envelopes at the same level as the tearable strip. Consequently, the protruding ends of the tearable strip can get caught on the machinery, or the tearable strip perforations can be separated.
OBJECT
It is therefore an object of the present invention to provide a method which will obviate or minimise the foregoing disadvantage in a simple yet effective manner or which will at least provide the public with a useful choice.

BEST MODE FOR CARRYING OUT THE INVENTION
The present invention provides a method of processing mail which utilises re-usable envelopes with or without a window. Either the leaf or leaves within the envelopes, or the envelope carries a machine readable address representative of addressee information.
Referring to the flow chart of Figure 1, in step 1, prior to being input into a mail assembly line, a destination or address 2 is preferably printed on the top or bottom of a leaf or covering sheet 1 of a letter or an invoice or bills or the like, which is to be sent alone or together with other leaves which are placed under it, as shown in Figure 2. Alternatively, the destination or address 2 can be printed instead or additionally on the back of the leaf or covering sheet 1 of a letter or the like. Optionally, a code or bar code 3, which is machine readable, is provided in the proximity of the address 2. Conveniently, the code or bar code can be provided on the face of an envelope in which the leaf or the like is to be placed. The position of the destination or address 2 and the code 3 are preferably pre-formatted by the use of suitable computer software so that it would always be printed in a fixed position. Preferably, an identical address 4 and code or bar code 34 are printed on the top left hand corner as well. The receiver will therefore be able to see his or her own name and address at the first sight after unfolding. Further processing from this point onwards can be done mechanically and automatically.
In step 2, the leaf or covering sheet 1, ie. letter, invoice, bill or the like to be carried by the envelope is mechanically fed into an assembly line, such that the address 2 on covering sheet 1 or other address that is carried by another sheet, will be placed immediately behind the window 6.
In step 3, the content of a letter is commonly mechanically folded into three equal or unequal portions as illustrated in Figures 3a and 3b. Conveniently, the letter can stay unfolded or be folded into two equal or unequal portions. Hence, after folding, the content of the letter will end up with a split end 5 at the base, and the destination or address 2 will preferably always end up in a legible orientation. This is the so called "rolling" way of folding. Alternatively, the content of the letter can be folded in a so called "zig-zag" way as shown in Figure 3 c. The folded letter will then have two split ends. When this method of folding is adopted, the address 2 and/or 4 (and/or an extra address 30) will have to be printed on the back of the covering sheet 1 in order for it to be visible through the window and therefore readable by a computer scanner or reader. Also, an additional code 32 will be provided and positioned the right way up for a machine to read. The machine has the functions of recording as well as sorting mail by region. The folding divides the letter into "n" (preferably three) panels with "n-1" fold lines between the panels. Alternatively, "n" equals one or two. Preferably the orientation of the address and the code or bar code is non-inverted and is in a legible orientation. Optionally, the address, or more than one identical address (or different address if the leaf or leaves is/are to be returned to the sender) can be printed on any other side or in any other position and orientation, namely upside-down or right way up, on the front or at the back, on the top or at the bottom, of the leaf or the covering leaf, or any combination thereof, such that after insertion through the bottom of the envelope, at least one of the addresses is positioned in the window for correct reading by the machine. This would have the same effect as inserting the pages in the "right way up" into an envelope when the opening or the flap of the envelope is below the window 6 along the bottom edge of the envelope when the envelope lies in a substantially vertical plane. Preferably the destination or address is provided or duplicated on the top left hand corner of the leaf or covering sheet.
In step 4, a pre-printed envelope, which has a window provided, for example, in any position and a prepaid postal indicia 22 (refer to Figure 4b) positioned on the same face, is mechanically held. The content of the letter can then be mechanically inserted into the envelope from the bottom through its opening, which is below the window, when the envelope lies in a substantially vertical plane. In other words, the envelope is oriented in a position where the flap 7 is at the bottom edge or the base of the envelope in first use. Alternatively, the pre-printed envelope has no window but a pre-printed address. The opening of the envelope in this case is underneath the address. Conveniently, when the envelope is not pre-printed, the content of the letter is still inserted through its opening, which is located underneath the postal indicia 22. Optionally, a return address is also provided and pre-printed on the envelope.
In step 5, the folded content of the letter is mechanically inserted into the envelope.
Referring now to Figure 4a, a filled envelope 5 is shown. Preferably, the front panel of the envelope (represented by A-A) is taller or longer in height than the back panel (represented by B-B). The destination or address 2 or 4 or 30 is shown through the window 6 which is on the front face of the upside down envelope 5. The importance of imprinting the destination or address 2 or 4 or 30 and/or the code 3 or 32 in an exact position is that it will be visible through a transparent or translucent window. The positioning of the window 6, as seen by the sorting machinery, accords with convention and therefore does not necessitate any changes to the machine setup. Alternatively, the window 2 can be provided in any position on the front face of the upside-down envelope 5.
The envelope can be closed by sealing its opening.
Turning now to Figure 4b, the back panel of the upside down envelope 5 is shown with a reusable sealing flap 7 which includes a tearable strip 8, which has a pair of adhesive lines there across, one adjacent the fold line between the front panel, and the other adjacent the distal edge of the sealing panel, with a protruding end 9 for grasping. The envelope includes side flaps .24 which can either be tucked under and adhered to the inside of the front or the back panel, or adhered to the external surface of the back or front panel. The sealing flap 7 includes two strips 10 and 11, which sandwich the tearable strip 8. The ends 9 are preferably inward of the side edges 12 of the envelope. The tearable strip is formed by a pair of spaced apart lines of slits, cuts or perforations 16 extending across the sealing flap. The lines of slits, cuts or perforations 16 are substantially parallel to the adhesive lines, being closely adjacent to the nearer adhesive line, so that in sealing, the sealing flap can be folded onto the back panel and the distal adhesive line adhered to the back panel, the material between the lines of slits, cuts or perforations being substantially removed and the adhesive line adjacent the fold line to the front panel being adhered to the back panel to allow the envelope to be re-used. The lines of slits, cuts or perforations 16 preferably do not extend fully to the outer ends 17 which increases the strength of the construction as the edges of the flap 7 and the strip 8 retain strength. Both of the strips 10 and 11 are gummed on their back. In first use, the envelope 5 can be sealed by gumming strip 10. The first receiver can then open the envelope 5 by tearing strip 8. Strip 11 will still be available for sealing when envelope 5 is re-used.
In a preferred alternative form of the invention, the tearing strip 8 has a gap 18 provided along its length, preferably but not necessarily centrally. This enables the envelope to be gripped from the centre gap 18 and each part of the strip 8 can be torn towards the ends of the strip. The cut- out part of the strip 8 may be such that the adjacent ends 19 have an arrowhead or pointed formation to assist in gripping of these parts. In this construction, protruding ends 9 are deleted as shown in Figure 4b. Optionally, the corners 20 of the flap 7 are cut away so as to further reduce the chance of the outer ends 17 getting caught on any machinery.
In step 6, the filled envelope is mechanically sealed.
In step 7, the address 2 or code 4 is read by a computer scanner for sorting purposes.
It will be seen that the foregoing invention has significant advantage over presently existing method of processing and sorting mail. In particular, the present invention provides' a way of eliminating the occurrence of a tearable strip being caught on, or accidentally or unintentionally torn open by, a roller. The smooth running of a mail assembly can then be ensured. It is an advantage of the construction that it can be used in all presently available mail inserting machines, i.e. where process of insertion proceeds with the leading edge forward, or sideway to the left or right.
The present invention also envisages a method of filling envelopes with no windows in such an orientation that the opening of the envelope is at the base when the envelope lies in a substantially vertical plane. In this case, a pre-printed address which is in an orientation that is readable by machines such as a computer scanner or reader and is legible, may be provided in any position of the envelope. Optionally, the address can be printed on the envelope after inserting the content. Optionally, a return address is pre-printed on the envelope. Optionally, a prepaid postal indicia is provided on the envelope.
