A comprehensive self-regulating control system applicable to all ANDRITZ lines with card and crosslapper.
The ProDyn technology creates constant interaction between the Dynamic card and the Dynamic crosslapper. It includes a scanning gauge and closed loop self-regulating.
The gauge at the end of the line monitors the fabric weight evenness in both cross and machine directions (CD & MD). Working in automatic mode, the ProDyn system pro-actively generates the fiber distribution at the delivery of the crosslapper by anticipating the batt deformation generated by the subsequent bonding process.
Accordingly, the Dynamic crosslapper lays down a heavier or lighter card web in a consistent manner, maintaining a loose fiber tension.
- optimizes the weight profile
- increases the final batt evenness
- generates fiber savings by reducing the average fabric weight and edges
