In the automation world, web handling, converting and roll-to-roll commonly refer to the organized conveyance of a long, thin, and flexible material. Typical processes are plating, coating and lamination of materials such as papers, textiles and films.
A web is generally processed by moving over rollers and through a variety of stations until all operations on the product are complete. The motivation to work with webs instead of sheets is normally economics in that webs are continuous, can be made at far higher speeds and do not have the start-stop issues of discrete sheet processing. The benefits of web handling include maximizing productivity and minimizing waste.
PMD has a long history of designing and building web handling equipment from bag machines to fuel cell MEA’s. Some examples of our experience and web handling knowledge are shown below.
