Hostile glass seaming application requires heavy duty, corrosion resistant modular solution

Glass processing is particularly demanding on linear motion components with its abrasive environment and high production rates. Glass edge grinding is a common process where the sharp edges of cut raw glass are finished for safe handling and to reduce chipping defects that can lead to breakages.

The most important and economical glass edge finish is seaming or arrissing, where the sharp edges of glass are chamfered on all 4 edges, top and bottom. This process is important to contain stress, like a frame, within the glass area while it is heated to over 800°C and then chilled, to create Tempered Safety Glass.

Without this process, the glass would simply explode into hundreds of tiny pieces during the chilling stage. When seaming experts Ashton Industrial designed their new fully automatic seaming line, SEAMMAXX-PRO, the objective was to simplify and reduce the cost. A further objective was to develop a clever system of using vacuum on moving transport belts to hold each glass firmly from the underside during seaming without any contact to the upper glass surface which can carry a delicate, coated heat reflecting film.
