Overview
Customizing your belts: However challenging the production process for belts is – Forbo Movement Systems offers a broad range of existing customized fabrication options and develops new solutions to meet specific customer requirements.

A range of perforations
A water jet cutter can perforate fabric-based conveyor belts with perforation diameters from 0.8 mm and in any belt width up to 3,900 mm. The machine can produce precise, consistent perforation patterns and other shapes with superior precision, benefiting applications such as digital printing where exact fit and consistent patterns are crucial.

Belt edge trimming of endless, wide belts
State-of-the-art trimmer capable of cutting wide endless belts to exact dimensions, ensuring straight tracking. Belt edges are cut cleanly and smoothly to improve belt efficiency and service life.

Folded-edge belt with flights
Flights can be added to belt edges so inside edges taper, forming beveled profiles that adapt when troughed. Folded-edge belts prevent products slipping or falling off at the sides and are ideal for inclined conveying (example: conveying deep-frozen pizzas downward on an inclined conveyor).

Milled grooves in curved belts
When welded-on profiles are technically not possible, grooves are milled into the top-face coating of curved belts to guide products (used where tight radii/distances prevent welding profiles).

Solenoid actuators in flights
Conveyor belts with milled pockets on the profile base are used for metered/portioned conveying where feed is controlled via actuators. These belts are hermetically sealed, suitable for the food sector, especially in combination with Smartseal which prevents fraying, contamination and wear. The design does not negatively impact the minimum drum diameter, enabling precise actuator control.

Belts with customized longitudinal profiles
Special longitudinal profiles can be added to the underside or top face of conveyor and processing belts. Profiles can be made to order or supplied by the customer; they can be tailored for dimensions, hardness and service life to meet specific conveying needs (example: conveying roof tiles requiring different profile hardness and dimensions).

Vacuum belt with milled grooves
Customized perforation and duct patterns are drilled into vacuum belts to match conveyed products, ensuring optimum air flow for secure conveying and discharge in applications such as sheet metal processing. Perforation patterns and milled air ducts can be configured for curved belts as well.

Open loop profile
Customized open loop profiles are offered for delicate mechanical conveying (example: mechanical apple harvesting where fruit must not be bruised), providing tailor-made solutions for superb functionality and efficiency.

Fabrication of roll-up doors
Roll-up curtains made of polyvinyl chloride (PVC) for large aisles in industrial and retail facilities. A custom high-frequency welding tool minimises cloudy areas on large windows in roll-up doors, improving view and safety in production facilities.
