Damage-free Tissue Handling with Bolzoni Auramo Roll Clamps

During the handling stages, paper rolls are subject to several damage risks, such as incorrect handling and shocks. To prevent rolls to get damaged, to avoid machine downtime and productivity loss, the choice of the correct paper roll clamp is the first step forward to a good handling practice.

The Paper Handling Specialist

For more than 70 years Bolzoni Auramo has been working in close cooperation with the paper industries worldwide, always finding better handling solutions. Well known for its expertise in forest products handling, the company holds the market leader´s position in sales of paper handling tools in Europe.

 

Bolzoni Auramo Cares for Tissue Paper Roll Handling

The pad edge is smooth and well rounded. Pad corners have large radius design, without protruding parts or edges.

“Damage free handling has always been our goal when developing new paper roll clamps”, says Lars Petersson, Bolzoni Auramo’s Forest Products Handling Division Manager.

“We have implemented an internal education program to give our sales force very high competence in paper handling. This allows us to advice our customers in a professional way. How to select the right clamp for dedicated handling? What’s the correct clamping force? What kind of contact pad is most suitable? These are the questions daily given to our sales force.”

 

Tissue paper roll clamps: engineered to suit the application needs

Tissue paper rolls often have larger diameter than the common other paper grades, which can be very extensive, even larger than 3,000 mm (120”) diameters do exist. As rolls are often very soft and loosely wounded, Tissue clamps have higher and wider contact pads to reduce surface pressure. The contact pads have a special form which is designed to reduce point loads under the pad edges. It is also common that large diameter Tissue rolls deform under their own weight when lowered down to the floor in horizontal position.This deformation causes a flat area which can in some cases be several hundred millimeters wide, with roll handling problems unless it is compensated in the clamp design.

Bolzoni Auramo has a wide variety of Tissue paper roll clamps, with capacities range from 1,500 to 6,000 kg (3,000 to 13,000 lbs.), and roll diameters are up to 2,700 mm (106”) in standard series. All standard Tissue clamp models have following features in common:

  • fast and effective 180-degree rotation, which enables effective handling of both vertical and horizontal rolls;
  • short and long pivoting arm design makes the clamps
  • versatile with a wide roll diameter range;
  • standard Tissue clamps are designed for handling on single rolls only, split arm models for handling two rolls are available on request;
  • special opening ranges, non-rotating and/or forward tilting clamps are available on request for special applications.

 

A complete range of damage reduction products

Bolzoni Auramo provides a number of state-of-the-art damage reduction options for a safer and more productive operation.
Here an overview of some developed specific products.

Contact pads. In most normal handling situations, the pads are the only parts of the clamp in contact with the paper roll. Therefore, as standard, Bolzoni Auramo Tissue roll clamps have a dedicated range of designed contact pads: Single radius, Triple radius or Convex radius pads, with wide variety of friction surface options.

Clamping force. Another key issue in Tissue handling is the excessive clamping force, which is one of the most common causes of paper roll out-of-roundness damage. The varying paper roll hardness, weights and diameter plus the high value of the rolls themselves are all factors requiring control of excessive clamping force on behalf of the operator. In this handling situation, we suggest using the Force-Matic, a fully mechanical pressure control system applicable to paper roll clamps in order to prevent overclamping causing roll out-of-roundness.

 

The Bolzoni Auramo Tissue paper roll clamps have higher and wider contact pads, designed to handle large diameter rolls and to reduce surface pressure on the soft paper.
The minimized pad thickness ensures good knifing properties when handling tightly stacked and bilge rolls.
