In recent years, the variety of packaging solutions on the market has grown exponentially, bringing with it a rising demand for attachments with highly specific shapes. Thanks to our extensive experience in the field, we are able to supply attachments in virtually any geometry. Timing belts with cleats are employed in high-speed, high-precision conveyor systems, particularly within the sectors of automatic machinery, packaging, and industrial automation.

Polyurethane attachments with metal inserts

Thermoplastic polyurethane (TPU) attachments are applied to the timing belt and can be welded onto the back at any position, giving the customer full freedom to choose the spacing of the attachments. Unlike belts with false teeth, the spacing does not need to be a multiple of the belt’s tooth pitch.

Typically, the desired geometries are achieved through mechanical machining. However, in cases where a large quantity of attachments is required, we can produce a mould to optimise manufacturing costs.

Dovetail Attachments

Timing belts used in conveyor systems are often exposed to high acceleration forces, and the density of polyurethane can make it unsuitable for certain geometries, resulting in attachments that are too heavy. By welding a dovetail-shaped base onto the back of the belt, it becomes possible to insert a secondary attachment made from a lighter material—such as glass-fibre reinforced plastic or carbon fibre—using an interference fit.

Attachments with Brushes

When handling fragile objects, rigid attachments cannot be used as they may compromise the integrity of the product. By manufacturing perforated attachments, brushes can be inserted to create a soft backing on the belt, allowing items to be gently deposited and transported without any risk of damage.

1 – Timing belts with cleats are used in the packaging sector and in automation

2 – The AT pitches are the most widely used as they guarantee precise positioning

3 – In order to facilitate changing of timing belts they can be supplied with pin joint

4 – Timing belt for the transport of lipsticks in the cosmetics sector

5 – Attachment with geometry used for transport of chocolate eggs in the packaging sector

6 – The metal part of the attachment reduces early wear of the box transport system

7 – Spring steel plates are inserted in the attachments in order to make them thinner and more rigid

8 – Timing belt, width 500 pitch T10 mm with rectangular cleats on rear

9 – Belt with central channel and attachment with threaded hole for vacuum suction cup fastening

10 – It is possible to screw on suction cups to create a vacuum on attachments with metal core

11 – Moulded attachment; a mechanical system is installed on the steel pins

12 – A magnet inserted inside the attachment improves adhesion with metal products

13 – The dovetail geometry allows interference fitting of lighter attachments

14 – The Delrin attachment attached by interference fit is mechanically locked in place with screws

15 – By inserting brushes on the attachments, a conveyor system for delicate products is created

16 – Belt with lateral brushes used in the pharmaceutical sector for packaging of pills

17 – Different colour attachments to identify the position in the format change

18 – Timing belt with polyurethane attachments with central area in neoprene foam

19 – By independently managing the two timing belts, it is possible to vary the distance of the attachments

20 – This type of attachment is used for forming of packaging in the beverage sector
