What is a bow roller? How does it help manufacturing industries?

     In this industry-centric blog, we are going to highlight about an important industrial product, the bow expander roller. 

Why bow roller is called so? Since the shape of the product is similar to a bow, it found its name from there. 

In the ensuing sections, we will be covering a lot of important subjects related to the product. This blog will further expand your knowledge about the subject. Industries using the product will draw benefits from the product.         

Design and construction 

To begin with, let’s share a brief about the design and manufacturing of thebowed rolls. The manufacturing-industry-centric product comprises a central beam with a bow in it, while bearings are mounted across the entire roll.

• Bowed roller
• Concave roller 
• D-bar 
• Dual bowed roller 
• PoS-Z  

How to measure the dimension?                

Considering its shape, many of you might be thinking, how do manufacturing companies measure its dimension? 

According to industry experts, the dimension of the bow is measured by arc height divided by roll width X 100.       

Unique features of the bow roller 

The bowed roll is identified with unique features that set it apart from the crowd. Here are a few unique features of the product:   

• Requires less maintenance 
• Width remains static 
• Resistant to abrasion 

• Resistant to chemicals
• High tensile strength  
• Resistant to wear and tear 
• Resistant to scratching and bumping 
• Excellent coefficient of friction 
• Quickly compensates for small changes that occur in the machine's precision  

Specifications 

The specifications of the bowed spreader rollers vary from company to company, it primarily depends on the type of industry and requirement. Here is the standard specification of the product:          

• Thickness: 12 mm to 15 mm 
• Size: 100 mm to 600 mm  

Application 

From the features section, let’s now shift our focus to the application of the product. As the bow expander roller is versatile, it serves many purposes. A quality-driven product offers applications, like reducing slack ends, wiping wrinkles, spreading, slit separation, coating batching, and re-winding among others.    

Industries drawing benefits and advantages from the bow roller   

The bow expander roller is integral to many web handling processes as a result the product has found its use in several industries. These includes:  

• Textile
• Plastic
• Paper
• Printing
