Applications

SOMATEC web accumulators ensure continuous material flow in every converting line — the buffer between process steps.

Coating lines — Buffering between unwinder and coating station for uninterrupted roll changes
Lamination lines — Compensating speed differences between lamination and winding station
Printing lines — Continuous web run even during roll changes or format changes
Calendering lines — Buffering between calender and winding for constant line speed
Converting lines — Wherever two process steps operate at different speeds

Why the ACC-P?

The pneumatic drive enables particularly direct control via the roller carriage position. Driven pull rolls ensure reliable web transport. The comb roller design enables easy threading.

Typical Configurations

Direct control: ACC-P with pneumatic drive and position control of the roller carriage
Reliable transport: ACC-P with driven pull rolls and web guiding
Compact buffer: ACC-P with comb design for easy threading during quick product change

Frequently Asked Questions

What characterizes the pneumatic accumulator? — The ACC-P uses pneumatically controlled dancer rollers instead of fixed mechanics. This enables particularly gentle web tension — ideal for sensitive, stretchable or thin materials.
What materials is the ACC-P suitable for? — Thin films, elastic nonwovens, coated papers and materials where pressure marks or stretching must be avoided.
Can the ACC-P be retrofitted? — Yes — SOMATEC delivers the ACC-P also as retrofit for existing converting lines.
