Replace bow banana roller with Arvind rubber bow roller and see the change

Rubber Bowed rollers are enormously used in several industries like paper, packaging and many more. But why it is necessary to use this type of bow banana roller? The importance of Rubber Bow Roller is to spread the web (process material) and keep it flat during several processes in web production equipment. The application is not limited for spreading or flattening of the web but it should also without any common errors. The spreading that occurs when bowed rolls are in place help to widen the web, separate slit webs prior to winding and eliminate wrinkles, creases and fold-overs. But, this requirement is not an easy task to achieve. If roller was not properly designed or manufactured then it gives a poor quality of work like wrinkles, shrank width and baggy centres. Hence, selection of roller is crucial to avoid such inaccuracies and give the best performance. It is quite challenging for a manufacturer and for a designer to make such type of roller to give a simultaneous high performance of multiple tasks.

Arvind rubber is the first ranked manufacturer, supplier and exporter of the high-quality product worldwide. Engineering and production team of Arvind rubber works round the clock to design and manufacture a perfect expander roller. The rubber expander roller is manufactured with consideration of key technicalities like wrap angle, bow angle and Lead –in lead-out distance. Sometimes, the roller is used in wet condition, if ordinary rollers will use the result will be a failure of the roller and defective web material. Arvind rub web control has crafted the roller which is compatible in dry as well as in wet environments. The high graded material which has properties like erosion resistance, temperature & chemical resistance is used to make it.  Even, these web rollers are appropriate for thin films and substrates like laminating paper, foil, and films. Moreover, the roller has wall mounting and foot mounting brackets with bow angle adjustment mechanism. It has special an innovative groove to enable give the best output. One secret is that if the roller is placed perpendicular to the web direction then the result will be incredible. Leave the ordinary one and select Arvind bowed roller for amazing outcomes.
