AUTEFA Solutions leads the way to Crosslapping Weight accuracy in the bonded lapped web is the most important quality feature for a nonwoven installation. The crosslappers of the Topliner series are characterized by high infeed speeds and precise weight distribution. Crosslappers take up the carded web coming from the carding machine with constant speed and gently bring it to the delivery belt. The crosslappers Topliner increase both web homogeneity and throughput speed and thus eliminate any bottlenecks. The uniform web laydown in conjunction with the WebMax and CLOSED LOOP system helps to save...

WebMax – web profile control technology AUTEFA Solutions WebMax produces a counter weight profile to avoid the smile effect. This is the key to product quality. WebMax ensures that the carded web weight is already being altered at the crosslapper infeed. Via the layering carriage control, the carded web is deposited on the layering belt in a way that the lapped web weight is controllably lighter in the edge areas compared to the center areas. This concave weight profile therefore compensates the weight changes due to material shrinkage and leads to the highest possible weight evenness in the...

Profile controlled by WebMax – the key to product quality EASY RETROFIT TO UPGRADE EXISTING NONWOVENS LINES TO INCREASE THE MD/CD RATIO No additional space required Short conversion times (installation within 3 days) No loss of the maximum layering width in case of retrofitting Short overall dimension for new crosslappers Can be retrofitted keeping the current control system and drives of the machine No additional switch cabinet required Separately controllable independently of profiling Independent of the manufacturer of the weight measuring system Surface weight distribution CONTINUOUS SAVING...

Short web path – minimizes false draft The Crosslapper Topliner is characterised by the following technical highlights, which all improve the quality of the layed web and lead to optimised production costs due to material saving. Only the Crosslapper Topliner (picture 1) has the unique short web path design, with a deflection of 180°, and its precise web laying minimizes false draft. DIRECT WEB TRANSFER FROM UPPER CARRIAGE TO LAYERING CARRIAGE The carded web is delivered from the card to the infeed belt of the crosslapper. Then the web is passed on to belt 1, which transports it to the upper...

OPTIMIZED CV-VALUES THANKS TO INTEGRATED WEB STORAGE WEBPLUS PROFILING REDUCES THE SMILE EFFECT The patented integrated web storage WEBPLUS increases product regularity and enables an improved CV-value. Contrary to carriage layers, working in opposite direction, the Topliner is equipped with an integrated web storage, which stores the arriving web during reverse movement of the carriages and delivers it during their constant movement. The capacity of the storage depends on speed and is continuously adjustable at the operating panel. The Topliner is equipped with the proven and patented profiling...

Special features Crosslapper Topliner PATENTED UPPER CARRIAGE DESIGN SANDWICH APRON SYSTEM The upper carriage guided the web by a patented roller arrangement. Deflection of the web is done in 2 steps each less than 90 deg. The web guiding between the sandwich belt system secures the carded web transport without additional mechanical parts draft between the belts. The Topliner is equipped with new designed transport aprons, which cover and secure the carded web. These aprons are antistatic treated, have a low surface weight and a high lateral stability. The apron tension can be adjusted pneumatically...

HIGH DYNAMIC DRIVE TECHNOLOGY CONTROL & SAFETY TECHNOLOGY The Topliner is driven from five infinitely variable high dynamic servo drives without external cooling. One motor each drives the upper carriage, the layering carriage, apron 1, apron 2 and the delivery belt. In this way the best laying results are achieved with an optimal coordination of speeds. The machine is controlled via a Siemens Simotion D-Controller, which is equipped with a high performance processor, in order to control the position-regulated movement sequences. The crosslapper Topliner is equipped with Siemens “Sinamics” converters....

Special features Crosslapper Topliner SL version DRAFTING UNIT-INFEED SPEED COMPENSATION BELT SC 123 The drafting unit at the infeed compresses the web and forms a counterweight profile on the delivery apron. This compensates the smile effect due to material shrinkage. Topliner crosslappers ensure weight uniformity after the bonding process. The drafting unit is part of the machines and needs no separate space. The speed compensation belt SC 123 ensures a continuous and smooth transport to the following machine without any false drafts. It compensates the discontinuous speed of the crosslapper’s...
