Mondi Š t ě ti 's 7 paper machine, improve the rewinding machine capacity and security

Bottleneck between winding and rewinding machine is obvious.This is also the Mondi Š t ě ti PM7 starting point of the implementation of the renovation project, PM7 special calender kraft paper production.In order to further improve the paper machine production reliability, Mondi decided to reform.Challenges mainly rewinding machine lack of ability to cope with increased production targets, and rewinding machine and not optimize the interaction between the reel.D the work of virtue is to find a safe and effective solutions, make complete production bottleneck breakthrough.

To seek solutions to raise the capacity of rewinding machine

Mondi senior project managerHelmut RiesenbergerTeam plans to increase the mother roll diameter, to minimize sampling and mother roll transfer, etc. The purpose of the manual operation.If reform cadres foundation, bridge type hoist crane and the drive motor, this will require a massive transformation, but also can not ensure the target efficiency.

D virtue put forward an economic and efficient technology solutions, meet all the requirements of improving capacity and safety.The basis of the need for costly renovation, also need not transform drive motor or bridge type hoist crane.D virtue solutions through customized, can be seamlessly there is no virtue existing d technology production environment.In the process of purchasing, Mondi Š t ě ti team with Poland's Mondi Ś wiecie factory has carried on the deep discussion, a few years ago the factory has carried out similar projects.Ś wiecie feedback and experience is positive and encouraging.

D another unique virtue and mature solutions, known as the Dual Unwind double refund paper system, can quickly change the mother roll and provide automatic stitching.Mother volume replacement and splicing during rewinding machine roll set.The solution to the existing rewinding machine provides the required capacity.The mother roll transfer through automatic transmission also guide rail realized fully automated, can now be more secure, more effective connection coiler and rewinding machine.

Professional project management

Transformation is very successful, and down time is short.Riesenberger stressed the good cooperation with d virtue: "everything is in good order.Timely delivery without delay."In addition, always open and good communication."The problem is always able to immediately solved."Riesenberger continued.With d his virtues of the project team cooperation also feel satisfied: "cooperation is very good."

Mother volume replacement time drastically reduced

Reconstruction result is very good: rewinding machine production capacity increased by 62%.Thanks to Dual Unwind, because according to the plan, rewinding machine mother volume replacement time is reduced, and the mother volume change during rewinding machine downtime is almost zero.Riesenberger emphasized the importance of DualUnwind: "quick female volume replacement is the key of this project.Mother volume replacement time drastically reduced.

Reconstruction result is very good: rewinding machine production capacity increased by 62%."   

Reduce the coiling paper quantity

Coiler area in unit volume water needle and pressure load optimization solution are also excellent results have been achieved.Reduces the winding loss amount of paper, and implements the effective volume change.Most importantly, increases the mother roll diameter.

The operator is safer

Provide solutions to meet all the latest safety regulations in the eu.Mother by installing automatic volume replacement system, the use of guide roll of paper from the reel to the rewinding machine, greatly improve the safety of operators.All delivery device specially designed, can ensure the safe operation and comply with safety regulations.In addition, the new safety MATS, safety bar and exit.

"We transform system compatible with the existing system, we are very satisfied.Reliability and efficiency are optimal."Riesenberger said.
