    • 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.
    • 本发明涉及一种搭接连接烟草片的方法,其中所述片段以重叠关系放置,并且重叠部分彼此粘合,而不需要使用外来粘合剂,通过施加于它们的压力和/或快速加热。 可以在辊之间或钳口之间施加压力,特别是电脉冲加热机的钳口。 在这种情况下,通过快速施加热量和压力而重叠的重叠部分可以被冷却,同时仍然保持在所述夹爪之间。 在搭接连接之前或之后,可以将固结剂施加到烟丝的端部。
