Belts for Merging and Diverting

Description
The sorter is the nucleus of the baggage handling system. All items of baggage checked in are merged in here and (depending on their destination) also diverted again at defined points. Merging often occurs at a 30° or 45° angle to the direction the sorter is conveying in. These conveyors either have one single wide conveyor belt (a full-belt merge), or several narrow belts that run parallel as a set (strip merges).

Technical Requirements of the belts
Both designs require the belts to have high surface friction to enable precise and slip-free transition of baggage to the sorter. In full belt merges, the belt runs over various deflection rollers and even over a knife edge. The coating materials must be able to absorb the temperatures caused by friction and flexing without becoming damaged.

In the case of strip merges, all belts operating in parallel in a set are stretched with just one tensioning roller. In order to achieve standard tension, compliance with tight length tolerances is a must.

All merge belts must meet the same technical requirements as curved belts.


Our solution

Forbo Movement Systems supplies belts with a low-friction fabric underside and a top face with the grip needed for both conveyor types. Belts with special, very flexible curved belt fabric and polyurethane as the coating material are predestined for use on full-belt conveyors.
Belts that run in parallel as a set are custom made for strip merges. We place top priority on precise manufacturing and compliance with the tightest length tolerances and, if required, the position of tracking profiles.
