From forest to end user, the production of tissue paper is a fascinating & complex process, yet a key maintenance practice is often overlooked during one of the final operations before packaging. As a Tissue log is being cut into retail size, the Log Saw doing the cutting must be extremely sharp to cleanly cut through the wound tissue & core.
This sharpness is maintained by almost constant contact with the unit’s grinding stones. Over time these grind stones load up with paper dust & glue and must be cleaned or “dressed”. This cleaning must be done several times per shift.
Failure to do so results in the stones rubbing the Log Saw rather than grinding, causing heat buildup & edge deterioration, translating into poor quality cuts, waste, and inefficiency. The presentation will offer a brief overview of “best practices” to prevent this from happening, leading to peak Tissue Line output.
Even with the advent of Auto-Grind systems, a company’s maintenance team should be familiar with the concept & practice of properly dressing Log Saw grindstones.

Converting facilities have undergone some very significant transformations over the past 30 years. Palletizing operations that used to be in the Warehouse have now become part of Converting. Consumer demands keep changing and calls for flexibility in Converting operations. The size of parent rolls has also grown over the same period.
Luckily, technology has made the rapid transformations possible. Thanks to sectionalized drives, Servo drives, AC Variable frequency drive, Advancements in PLCs, etc. All the major pieces of equipment in Converting have also become very automated.
The machines are also more capable than ever. A good converting facility design begins with the layout. Preferably a good compact layout that takes into account: optimization, flexibility and productivity. Cost is also a major factor.
This presentation will provide a step-by-step approach on how to address all the key factors. This will also highlight some key concepts and principles needed to guide the design process.
The outcome of the process will be a Converting facility that will be highly optimized, flexible, and very productive.

The North American paper manufacturers continue to require top-quality maintenance practices on its already aged installed base to remain competitive in the global market.
By mixing the perspectives and experiences from paper producers and machinery suppliers, this paper presents a comprehensive assessment of both challenges and opportunities on equipment maintenance planning and execution.
It covers topics such as difficulties to hire experienced personnel, challenges to reduce equipment spare parts lead times, partnerships with equipment suppliers, recommended best practices to reduce vulnerability, and how to use new technologies in your favor.
The aging workforce is a known and worrying factor, as top-quality maintenance is dependent on experienced technicians.
The suppliers have been affected by the lead times for spare parts, so the mills need to learn how to adapt their maintenance budgeting cycles to this new reality. For cost reduction initiatives, all mills try to keep their spare parts inventories at a minimum, but many suppliers have similar goals and targets.
These are some of the topics that must be taken into consideration for everyone that is seeking improvements for their maintenance practices.

One of the customer requirements established for pulp supply is the intrinsic viscosity. This property is a measurement of the degree of polymerization of the cellulose monomer chains after pulping, in a cuproethylenediamine solution, indirectly showing the degradation of the fiber during the kraft process.
In paper industry, there are mentions about the pulp intrinsic viscosity as a direct influence on the strength of the paper.
In order to determine this relationship with the mechanical property expressed by the tensile index, physical tests were carried out on handsheets, analyzing various levels of intrinsic viscosity, to establish whether or not there is a correlation between these properties.
In addition, aiming integrated mills with paper machines, the difference in the viscosity of dry pulp and slush (5% dry content) was also evaluated, in order to analyze the effect of hysteresis on this property. According to the literature, studies show that viscosity [cP] does not directly affect the paper's tensile index, since it is also greatly influenced by other properties of the pulping process and by the anatomy of the fibers themselves.
The consolidated results of the analysis of intrinsic viscosity [dm3/kg] will be shown in the final version of the paper.
Mark Christopher, Global strategic Market Manager – Tissue, Buckman International
Refiners are a long standing fixture on tissue machines but it is important to understand that they are a carryover from the flat sheet paper industry.
Although this mechanical step is effective at creating strength, no idealist would design a tissue machine targeted at the premium bath and facial market with refiners, if they could avoid it, due to the costly negative side effects.
The unwanted effects include increased fines, sheet densification and an increased tendency for final product dusting to name a few. Fourth generation biotechnology provides a sustainable way for tissue makers to achieve higher quality base sheet characteristics with lower input costs while idling refiners.
13:30 - 13:45 Best Practice and Future Innovations in Roller Covering and Management in a VUCA World
Giullaume "Billy" Bordais, Global Tissue Converting Expert, Hannecard Group
In turbulent times, key indicators of success are nimbleness, robustness, and the ability to gather and integrate quality intelligence. Embossing stations impart or destroy many essential characteristics of tissue – and their rollers directly impact product quality & production speed. Thus, roller selection and management significantly influence these key success indicators.
Today, best practices in Roller Covering includes:
- Optimization of roller performance beyond extended lifetime. Developments in glue-less lamination and hot embossing require corresponding improvements in roller covers. Focusing on rollers’ impact on final tissue quality and line-speed improves robustness and increases capacity.
- Partnering with roll suppliers who can provide dynamic nip simulations of coating options, enabling Tissue Converters to nimbly adapt to changing products, patterns, and volumes
- Employing Roller Management Platforms which crosslink performance and roller data and facilitate open, collaborative relationships between end users and suppliers. This easily accessed, quality information allows for learning systems and better predicative models -opening the door for true gain sharing and “assets as a service” models.
With minimal investment, best roller practices enable tissue converters to reduce downtime, and improve profitability and consumer satisfaction. Although our volatile world presents challenges, we are excited to face these challenges better equipped.

The tissue machines are subjecting any optical measuring equipment to the harshest conditions in the paper industry. This is due to the high amount of furnish particles flying around within the camera images.
A key component is the design of an optical sensor withstanding those conditions in a 24/7 production process. A compact and robust all-in-one Sensor containing a Camera, Illumination, and a cleaning method to deliver crystal-clear images has proven itself in practice.
The second key topic is understanding to focus on inspection and monitoring tasks that drive production efficiency.
Web monitoring cameras need to monitor relevant process conditions like the detection of edge cracks, the emergence of wrinkles and the creeping blade's condition.
Web Inspection Systems focuses on process-relevant defect detection and classification of holes, edge cracks, repeating defects, and middle-cut inspection on wide machines.
The optimum effect is achieved by combining WIS and WBM systems enabling the traceability of defects back to the origin making the root cause analysis efficient.
The defect data processing sent to the converting line is another addition to the portfolio of these systems.
