ABSTRACT:
During manufacture, a rubber or other elastic sheet is forcibly stretched out and smoothly affixed to an adhesive spread out on a backing of cardboard or similar material. The sheet is suitable for receiving typing from a typewriter, and the entire assembly is suitable for insertion and bending over the roll of a common typewriter. During operation, a person types a message on the sheet, removes the assembly from the typewriter and forcibly peels the sheet off the backing. The sheet returns to its original unstretched shape, and the typed words, along with the spaces between the words, occupy less space than those of a similar message typed on ordinary paper. When used with a Xerox or similar copying machine, the reduction in the size of the words and spaces permits the use of many more words per final, normal size page of reproduced document.
