Sheet carrier for tractor-feed printers

Carrier assembly, for carrying individual sheets of paper through a printer, comprising a carrier sheet and pockets;

• wherein the pockets are formed by the provision of a double thickness band extending across the carrier sheet;
• wherein the width of that band is in two contiguous portions, and over one portion of the width the two thicknesses of the double thickness band are firmly adhered together, and over the other portion the two thicknesses lie against each other without adhering, and wherein the carrier sheet is in several pieces, joined together by overlapping joints, and wherein the area of overlap between neighbouring pieces comprises the double thickness band.

Method for enabling individual sheets of paper to be printed on a printer, comprising the steps of providing a set of identical pre-glued strips and a single carrier sheet;

• of placing the ends of the carrier sheet in abutment so that the sheet comprises an endless loop;
• and of holding the ends in abutment by virtue of their both adhering to one of the strips, and of sticking the rest of the strips to the carrier sheet to form pockets at appropriate intervals.

Method of manufacturing pre-glued strips for us in a carrier assembly for carrying individual sheets of paper through a printer, comprising the steps of applying adhesive to the strip;

• of superimposing a backing layer over the adhesive;
• of peeling off a portion of the backing layer to expose adhesive;
• and of sprinkling talcum powder or french chalk onto the exposed adhesive so as to substantially disable the adhesive.
