Abstract
Abstract The method of establishing accurate registry of one or more superposed flexible sheets relative to first and second support surfaces whereby the sheets can be removed from the first support surface and placed in proper registry on the second support surface. The method comprises the steps of defining in a first sheet a plurality of elongated, rectangular openings, placing the sheet on the first support surface and firmly anchoring on the first support surface a plurality of upstanding first pins of corresponding elongated rectangular cross section with each first pin conformingly penetrating one of the openings, removing the sheet from the first support surface and placing it on the second support surface and firmly anchoring on the second support surface a plurality of upstanding second pins with each second pin penetrating one of the openings. At least one of the second pins is square in cross section with a transverse side dimension equal to the length of the shorter side of the rectangular openings, whereby the sheet can expand or sweep in the direction of the longer sides of the opening penetrated by the square pin. Subsequently, any other sheet provided with openings for snugly receiving, respectively, the first pins on the first support surface can be transferred to the second support surface and registered with the first sheet.

Claim 3
Dependent Claim
97 words
The method of claim 1 in which said one sheet is formed with a pair of said openings, the major side edges of said pair of openings being generally aligned, and in which the other of said second pins is identical in size to said first pins conformingly to penetrate one opening of said pair, the second pair of faces of the one shorter second pin being in retaining contact with the major side edges of the other opening of the pair to guide the sweeping movement of said one sheet away from the other second pin.
Claim 4
Dependent Claim
52 words
The method of claim 2 in which one of the first faces of the one shorter second pin which is remote from said other second pin is, at least initially, in contact with the minor side edge of the other opening, which minor side edge is remote from said other second pin.
Claim 5
Dependent Claim
90 words
The method of claim 1 in which said one sheet is formed with a center opening and an opening on each side thereof, the major side edges of these three openings being generally aligned, in which the second pin penetrating the center opening is identical in size to said first pins conformingly to penetrate said center opening, and in which the second pins penetrating, respectively, the openings on each side of the center opening have second faces of significantly shorter transverse dimension than the length of said major side edges.
Claim 6
Dependent Claim
65 words
The method of claim 4 in which one of the first pair of faces of each shorter second pin which is remote from the center opening is, at least initially, in contact with the minor side edge of the opening penetrated by the pin, which minor side edge is remote from the center opening, whereby said one sheet can sweep away from said center opening.
Claim 7
Dependent Claim
123 words
The method of claim 1 in which said one sheet is formed with two pairs of such openings, the major side edges of the openings of each pair being generally aligned with the major side edges of the openings of one pair being generally perpendicular to the major side edges of the openings of the other pair, and said openings being disposed so that a line drawn between the centers of the openings of one pair generally perpendicularly bisects a line drawn between the centers of the openings of the other pair, and in which the second pair of faces of the second pin penetrating each of said openings is of significantly shorter transverse dimension than the length of said major side edges.
