Crosslappers must take up the carded web coming from the carding machine with constant speed and gently bring it to the delivery belt. The carded web passage in the layering belt system is of considerable importance. When running high lapping speeds, additional system components, such as internal web accumulators in the crosslapper, ensure a weight-neutral and straight-edged carded web deposit in the reversing unit of the layering carriage. In connection with the crosslappers of the Topliner-series WebMax ensures a maximum of weight accuracy in the final product. THE DYNAMIC LINK OF...

Profile controlled by WebMax – The Key to Product Quality Weight accuracy in the bonded lapped web is the most requested quality feature for a modern nonwoven installation. For bonding of lapped web of any type, drafts and speed accelerations in the lapped web are necessary. Even with draft-free bonding systems, the lapped web is often being drafted in order to reach the desired bonding ratio (MD/CD) for the requested nominal weight in the final product. These drafts, however, cause a reduction in product width, the socalled material shrinkage. It is larger in the edge areas than in the...

Web Infeed WebMax: The carded web weight varied depending on the layering width. The correct setting is effected either manually or fully automatically. Carded Web Lapping: The precise cooperation between web infeed and web lapping ensured exact position profiling of the carded web with a straightedged layering pattern. weight weight Profile without WebMax: The classic weight distribution in an needled lapped web shows the typical higher weights in the edge areas. Profile with WebMax: The concave weight profile on the delivery belt will be compensated again by the following bonding...

Topliner CL 4000 PF – The Crosslapper for the Paper Felt Industry Needling felts for paper machines were and are subject to especially high quality requirements. In the past, best product results required relatively low production speeds during lapped web production. With the Topliner CL 4000 PF AUTEFA Solutions introduced a finish-lapper to the paper felt manufacturers in the market, which is able to double the production performance. This is possible by the lapper principle of the CL 4000 with short carded web passage and a patented layering belt guidance in the laydown area. Additional...

Crossliner CL 2002: The intermediate lapper produces optimal fiber infeed for the fine carded web carding machine. Web Guidance: By means of the synchronous carriage movement, the carded web is brought to lapping via the front layering belt. Topliner CL 4000 PF: The finish-lapper processes light and sensitive carded webs with high speed and at the same time ensures perfect layering strength. /7
