Closed Edges - This is a procedure performed to protect the edges of PVC or polyurethane belts.  The edge is protected to insulate the fabric structure from the infiltration of conveyed material in order to ensure a longer wear of the belt and to comply with standards on hygiene.

On request, CHIORINO will carry out the special applications described below on endless or roll conveyor belts.  The CHIORINO S.p.A technical department is available to provide you with more information.

Guide Buttons - In special instances when the belt must be kept perfectly in place, PVC or polyurethane guides can be replaced with excellent results by "buttons".  These buttons allow drums with smaller diameters to be used.  Made of plastic, they are smooth-running and wear-resistant; they are riveted  on the belt, on one or both edges.  At least 3 "buttons" must be in contact with the drum (fig2); the pitch between buttons will be consequently determined by the roller diameter.
