EMBOSSING AND LAMINATING MACHINE WITH EMBOSSING CYLINDERS HAVING DIFFERENT ROTATIONAL SPEED

摘要

Embossing and laminating machine comprising a first embossing cylinder (3) with a surface provided with a first set of protuberances, a second embossing cylinder (5) with a surface provided with a second set of protuberances the said two embossing cylinders forming a nip, and a first and a second pressure roller (7, 9) interacting with the first and the second embossing cylinder respectively; and in which the protuberances of the said first and the said second sets are made in such a way that in the said nip some of the protuberances of the first set coincide with some protuberances of the second set, while other protuberances of the first set are out of phase with corresponding protuberances of the second set, characterized in that the two embossing cylinders are mechanically connected by a transmission which does not keep the cylinders in phase and which causes slight relative slippage between them. 167 ז' באייר התשס" א - April 30, 2001
