Abstract

A strip of envelopes is formed by folding a web 1 of, e.g., paper or providing two webs to form layers 4 and 5, crimping gluing or heat-sealing the layers together in regions 6 and forming cut-outs 7 and slits 8. <IMAGE>

Description

SPECIFICATION Improvements in continuous stationery The present invention relates to the manufacture of an item of continuous stationery consisting of a series of envelopes which are suitable for mailing advertising material, for example. The invention is defined in general terms in the claims which follow and will be described by way of example only with reference to the accompanying drawing showing diagrammatically the sequence of operations performed in the manufacture of such an item by a continuous process.

Referring to the drawing, a web 1 of paper of suitable thickness and strength has a film of adhesive 2 along one edge. The web is passed con tinuouslyfrom right to left through a suitable machine, in a first stage of which indicated at A, the web is folded along a line 3 to form superimposed layers 4 and 5 of unequal widths, so that the layer 4 includes a portion projecting beyond the edge of the layer 5 and bearing the adhesive film 2. In a second stage indicated at B, the layers are subjected to a crimping operation to form regularly spaced, transversly extending interconnected regions 6. Finally, in a third stage of operation indicated at C, the web is cut at the location of each interconnected region 6 to remove a triangular cut-away 7 from the projecting edge portion and form a pair of aligned slits 8 within each such region.

The resulting product thus consists of a series of envelopes each having an adhesive flap 9 and being connected to those adjacent to it by central and end portions 10 which may be easily torn to separate the envelopes after addressing in manual or automatic machinery.

Modifications may be made to the embodiment described above. Thus, the order in which the steps are carried out may be varied and they need not be performed on the web in sequence. The flaps 9 may be devoid of adhesive, the regions 6 may be joined by gluing or heat sealing, and more or fewer slits 8 may be provided in each region. Instead of using triangular cut-outs to define the flaps, this may be done by further narrow slits. Perforations may be used instead of slits. Materials other than paper may be used, while two separate webs may be employed instead of a folded web.

1. An item of continuous stationery comprising a web folded along a longitudinal line spaced from the centre-line of the web, thereby forming two overlapped layers, a portion of one layer projecting beyond the edge of the other, regularly spaced transversly extending regions of the layers being interconnected by crimping, and the web having transverse lines of severance to facilitate separation of the web into a plurality of envelopes each having a flap formed by part of the projecting portion.

2. A modification of the item claimed in claim 1, wherein the layers are interconnected by means other than crimping.

3. An item of continuous stationery substantially as hereinbefore described.

4. A method of making an item of continuous stationery substantially as described with reference to the drawing.
