Linearly-acting Lay-on Roller

Over time lay-on roller technology evolved from simple pivoting support arms, to pneumatically loaded, and then the individual lay-on roller system was introduced. However, these individual lay-on rollers added complexity and room for error due to the difficulty of not knowing how much lay-on nip force to apply. Thus, linearly-acting lay-on roller systems were developed to provide better nip force control.

Evolution of the Lay-on Roller

Today’s web converters are challenged with production requirements that are becoming increasingly difficult to satisfy with the technology of their older slitter rewinder equipment.Roll quality standards are harder to achieve as materials being processed are thinner, have lower modulus and have either very high or very low coefficients of friction, or when production speeds and finished roll sizes continue to increase. One area where we have seen gains being made is the development of improved lay-on roller systems that help address these process challenges.
