Lapping machine WebMax

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 final product. With the improvement of the lapped web profile WebMax also leads to a proportional reduction of raw material consumption. A special advantage of this system is that it relates exclusively to the crosslapper Topliner. The WebMax does not require any separate space, and can be retrofitted with a lapper of the Topliner- series. Advantages: ■ Compensation of the smile effect caused by material shrinkage ■ Two independently controllable drafting zones create a counterweight profile on the delivery apron 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 Continuous saving of fibers
