Physics of nip rollers Physics Forums
21.08.2013 So to get the nip rollers to transmit the appropriate force to the belt, it is not enough to set the drive system correctly, since the roller could just slip. You also have to apply a great enough normal (squeezing) force so that the entire frictional force desired can actually be transmitted. Example: If the coefficient of friction between the roller and the belt is 0.1, and

WO2018063447A1 - Nip roller and method of manufacturing ...
A nip roller and a method of manufacturing a film roll body are provided, which achieve both high quality and productivity of plastic films to be produced, without causing polygonal deformation even when plastic films are produced with large width and at high speed. The nip roller of the present invention has a core material having a surface coated with rubber.
MoreWhy is the roller nip so important? - Nip Control
The roller nip is critical for offset printing since it both transports and processes the ink and fountain solution. This technology is unique in that the process components, ink and water, are mixed under pressure during printing, creating a new solution. Contact width - estimated by applying ink to the rollers, rotating them and measuring the width of the stripe - varies

You might choose pressure control when you know that your system spring constant will change over time; you want to avoid excessive loads; or you want to take the need for skill out of the repeatability of the compression. Nipped rollers, used in many processes, rely on high pressure created by rolling a web between two pinching rollers. In nipping roller systems, you have the

NIP ROLLER INDUCED CONTACT STRESSES
A nip roller typically involves two rollers, one whose surface is incompressible (i.e., rubber and like materials) and one whose surface is compressible (i.e., typically a metal material). There are two common applications of nip rollers in web lines. One application is that of a pacer or drive roller. The purpose of this type of a roller is to control the tension and velocity of the web. To ...
