Abstract
Memorabilia insert sheets are pressed against a support sheet having rows and columns of small area self-stick visual fiducial adhesive zones imprinted thereon. Since the adhesive in the zones is releasable and reusable, misaligned insert sheets may be readily mounted upon the support sheet a number of times by an unskilled user until the insert sheet edges are parallel with respect to the support sheet edges and the surrounding borders are even. A transparent cover sheet is then laminated to the insert sheet by the application of heat and pressure to make a long-lasting, attractive display.
Claims26
A laminatable envelope comprising:
- (a) an insert sheet support sheet having a light transmissive cover sheet affixed to said support sheet, said light transmissive cover sheet having a cover sheet adhesive upon major portions thereof and facing a front face of said support sheet;
- (b) a plurality of insert sheet alignment assisting adhesive zones positioned upon said support sheet comprising readily releasable and reusable pressure sensitive self-stick adhesive, the total area occupied by said adhesive zones being small relative to the area of the front face of said support sheet to facilitate easy removal and realignment of misaligned insert sheets mounted upon the front surface of said support sheet while also providing bonding areas between said adhesive zones, enabling said cover sheet adhesive to bond said cover sheet to the bonding areas upon the front face of said support sheet.
A laminatable envelope comprising:
- (a) a core sheet having a first light transmissive cover sheet affixed to said core sheet, said first light transmissive cover sheet having a cover sheet adhesive upon major portions thereof and facing a front face of said core sheet;
- (b) a second light transmissive cover sheet affixed to said core sheet, said second light transmissive cover sheet having a cover sheet adhesive upon major portions thereof and facing a rear face of said core sheet;
- (c) a plurality of insert sheet alignment assisting adhesive zones positioned upon the front face and the rear face of said core sheet, said adhesive zones comprising readily releasable and reusable pressure sensitive self-stick adhesive, the total area occupied by said adhesive zones being small relative to the area of the front and rear face of said core sheet to facilitate easy removal and realignment of misaligned insert sheet mounted upon the front and rear faces of said core sheet while also providing bonding areas between said adhesive zones enabling said adhesive to subsequently bond said cover sheet to the bonding areas upon the front face of said core sheet.
A method of making a lamination of at least one insert sheet comprising the steps of:
- (a) providing an insert sheet support sheet having a plurality on insert sheet alignment assisting adhesive zones upon a support surface thereof, said adhesive zones including readily releasable and reusable pressure sensitive self-stick adhesive, the total area occupied by said adhesive zones being small relative to the area of the support surface of said insert support sheet to facilitate easy removal and realignment of misaligned insert sheets mounted upon the support surface of said support sheet while also providing bonding areas between said adhesive zones;
- (b) pressing one or more insert sheets against said adhesive zones to mount said insert sheets upon said support sheet;
- and
- (c) thereafter laminating a light transmissive cover sheet to said support sheet.

A method of making a lamination of at least one insert sheet comprising the steps of:
- (a) providing an envelope having a light transmissive cover sheet affixed to a minor portion of an insert sheet support sheet, said support sheet having a plurality of insert sheet alignment assisting adhesive zones upon a support surface thereof, said adhesive zones including readily releasable and reusable pressure sensitive self-stick adhesive, the total area occupied by said adhesive zones being small relative to the area of the support surface of said support sheet to facilitate easy removal and realignment of misaligned insert sheets mounted upon the support surface of said support sheet while also providing bonding areas between said adhesive zones;
- (b) pressing said insert sheet(s) against said adhesive zones to mount said insert sheets upon said support sheet;
- (c) repeating step (b) upon misalignment on an insert sheet with respect to edge portions of said light transmissive cover sheet until said misalignment is eliminated;
- and
- (d) thereafter laminating said light transmissive cover sheet to said support sheet.
