Abstract

The invention concerns a method of lap joining pieces of tobacco in which the said pieces are placed in overlapping relationship and the overlapping portions are adhered to each other, without using extraneous adhesive, by the application to them of pressure and/or rapid heating. Pressure may be applied between rollers or between jaws, particularly the jaws of an electrical impulse-heating machine. In this case, the overlapping portions lap joined by the rapid application of heat and pressure may be cooled while still held between the said jaws. Prior or subsequent to lap joining, a consolidating agent may be applied to end portions of the tobacco pieces.
