ABSTRACT:
A method for bonding, cutting and printing sheets of polymeric material is provided which comprises the steps of: (a) forming first, second and third patterns of an infrared-absorbing material on one of the sheets, the first pattern corresponding to the locations at which the sheets are to be bonded together, the second pattern corresponding to the locations at which the sheets are to be cut, and the third pattern corresponding to the locations at which the sheets are to be printed; (b) contacting the sheets with one another; (c) exposing the contacted sheets to infrared energy; (d) applying pressure to the sheets; and (e) cooling the sheets. The amount of infrared energy to which the sheets are exposed and the distribution of the infrared-absorbing material are chosen so that 1) the sheets bond to one another in the areas of the first pattern, 2) the sheets are cut in the areas of the second pattern, and 3) the sheets are neither bonded nor cut in the areas of the third pattern. In certain preferred embodiments, the infrared-absorbing material is xerographic toner and the patterns are formed by a xerographic process.
