Frequently Asked Questions

1 Does TALLERES AMERICA really owns all the machinery once running for THE LANGTON COMPANY for the manufacture of corrugating rolls?

Yes! Today we have all the machinery once owned by LANGATON, starting with Bristol facility in England, and all the machinery from Cherry Hill’s facility in New Jersey. Our working capacity increased drastically once all these machines were installed, and by the year 2003 are ready to work for you.

2 By working with all machinery and tooling once owned by LANGSTON CO, does TALLERES AMERICA is limited to the profiles standardized by Langston for the different kinds of flutes?

It’s important to outstand that TALLERES AMERICA, with the new acquisition of first class creep feed grinders, has the ability to grind any kind of corrugated profile or flute. We are not limited to the Langston standards, we have all the tooling and CNC devices to grind diverse profiles and even special designs for our customers.

3 What determines quality in corrugated boxes?

There are two general factors that will make you produce quality boxes: first, a strong and well designed corrugating unit, second, a strong and well designed set corrugating rolls.

4 What do you use as base material for your rolls?

In TALLERES AMERICA we have developed the steel alloy that best suits as base material for every kind of roll we manufacture or rebuild. Continuous investigation has brought up steel alloys with excellent mechanical properties such as hardness, impact and abrasion resistance which are essential due to its working conditions.

5 What’s Take-up-ratio and how it affects our economy?

TAKE-UP RATIO is the relation between the amount of medium paper and liner paper utilized by a single facer to produce corrugated board. This ratio lets us know the utilization of medium paper in our process and having an adequate supervision over the parameters that control this factor can represent significant savings for your company.

6 Does it really “hits our pocket” having a high take-up ratio?

Any alteration in the flute profile will change the take-up ratio, and that may represent an unnecessary consumption of medium paper when we produce the same amount of corrugated board. This factor can get higher by two means: when the flute depth is larger than the design dimensions and when the diameter of the lower corrugating roll gets worn. In both cases we will be producing the same amount of corrugated board with a higher consumption of medium paper.

7 Talking about coatings for corrugating rolls, is your chrome plating as good as your competitors’ ?

TALLERES AMERICA can supply corrugating rolls with NuChrome, which is world-wide known for high precision and durability. Also, we can apply Duro-Crom which is a 0.004” thick chrome plating process which has been developed by TALLERES AMERICA’s research department with excellent application on flute profiles.

8 Is it that important to repair the pressure roll each time we mount new or ground corrugating rolls?

The pressure roll is one of the most important elements to consider for proper performance of our single facer. It is designed to keep uniform pressure throughout the entire length of the roll, in order to properly glue liner and medium paper. This is the reason why we highly recommend to change or repair your pressure rolls every time you mount a new or reground set of corrugating rolls.

9 What is crowning?

Crowning is the difference in diameter between the center and ends of the roll body forming a curve in its surface. The purpose of this curve is to guarantee uniform pressure throughout its length once being subject to flexion by forces applied in its journals. Precision crowning in our corrugating or pressure rolls are always required to avoid air bags in our finished product. The precision required for this job is only obtained by state-of-the–art machinery designed specially for the task.

10 What are flutes?

Considering the ancestral principles of an “arch”, when corrugated cardboard was conceived people wanted to apply these benefits to paper, and put arches in the corrugated medium. These arches are known as flutes and as part of the finished cardboard, resist bending and pressure from all directions. Flutes come in several standard shapes and are designated by the letters A, B, C, E, and F.

11 What is ECT?

ECT, or edge crush test, is performed to predict the vertical strength of corrugated board. The test determines the resistance to compression of the flutes in pounds per square inch.

12 Which is the best material for making boxes?

Corrugated boxes are the best choice for the application, is both lighter and less expensive than alternatives like plastic, wood, and metal, plus it is 100% recyclable. Unlike other types of boxes, corrugated boxes fold down flat for storing and shipping, which saves you money and floor space. Corrugated is strong enough for stacking, resistant to impact and vibration.
