across the form by longitudinally extending perforation lines 92 labels 94 are integrally formed in the form 80 by scoring defining circumscribing lines of weakness 96 although it may be appreciated that the labels could also be formed by perforations 98 at a corner or along an edge of the top ply sheet 100 of the form 80 as may be seen in fig7 and 9 an adhesive layer 102 is applied to the top ply sheet 100 between a release sheet 104 and the rear face 106 of the top ply sheet 100 the adhesive layer extends within a boundary 108 which extends outward of the lines of weakness 96 relative to the label the release sheet 104 is coined with a release coming 110 of e g silicone in a release zone 112 as shown in fig9 the release zone 112 is relatively interior to the boundary 108 and is surrounded on the release sheet 104 by a coating free zone 114 the coating free zone 114 extends around the edge 116 of the release sheet 104 including bottom edge 118 side edges 120 and 122 and top edge 124 fig1 shows the form 80 with the release sheet 104 attached to the rear face of the top ply sheet 100 it being seen that the release sheet 104 occupies only a fraction of the area of the top ply sheet 100 the form 80 may include additional layered sheets as in form 20 joined.
