What is Nip Rolls? Nip rolls are a pair of rollers that are used to compress and hold materials together during a lamination process. They are commonly used in the glass industry to laminate glass with other materials such as plastic, metal, or even other types of glass. The nip roll system consists of two rollers: a top roller and a bottom roller.
nip is the pressure between two rollers that are forced together. A nip impression is a measure of the uniformity of that pressure. The pressure profile is sometimes referred to …
Tms research focuses on rubber covered nip rollers. Non-uniform nip loading has been proven to be a means of laterally moving a web. Rubber is a nearly incompressible substance and when loaded in the geometry of the nip the rubber velocity increases as it passes through the contact zone. Tills is analogous to a problem in which a fluid is 2
Nip roller units can also be used as pullers for material being pulled off of rolls or being fed between operations. Nip rolls are sometimes called laminating rolls, laminators, squeeze rolls, pinch rolls or even wringers. Smoothing Press. This is a rotary lamination press used to squeeze an adhesive coated sheet onto a substrate.
Rollers are widely used in web handling. Rollers can be either driving the web or driven by the web. The material for the roller depends on the demands of the process in which it is used. A nip is any two rollers in contact where the contact surface is pinched or nipped between the rollers. A nip is illustrated in Figure 1-1.
