Transilon Technical Q&A (Applications)

Q. “Which belt properties are suitable for inclined conveying?”

A.　For inclined conveying, the balance between the coefficient of friction (µ) and lateral rigidity (rigidity across the belt width, often referred to as “transverse stiffness”) is most critical. If the coefficient of friction is insufficient, slippage will occur; if it is excessively high, it can increase drive load and accelerate wear. With Transilon, the required and sufficient friction characteristics can be achieved by selecting the appropriate surface pattern and coating material according to the application.

In addition, insufficient lateral rigidity can lead to belt mistracking or side drift, so it is important to select the belt structure based on the incline angle, conveyed load weight, and the presence or absence of guides.

Q. “Which properties should be prioritized for long-distance horizontal conveying?”

A.　For long conveying distances, reduced running resistance and dimensional stability are key selection criteria. Amp Miser’s Texglide technology reduces friction on the underside of the belt, thereby lowering drive motor load and energy consumption.

In addition, the Transilon construction with extremely low elongation helps reduce the frequency of re-tensioning and contributes to improved overall line maintainability.

Q. “Which technical characteristics are important for high-speed conveying lines?”

A.　In high-speed conveying, low elongation characteristics and dynamic stability are essential. Belt elongation and thickness variations can cause mistracking and vibration as speed increases.

Siegling Transilon minimizes elongation through optimized tension member design, maintaining positioning accuracy and running stability even at high speeds.

Q. “What characteristics are suitable for logistics and warehouse conveying?”

A.　In logistics applications, a balanced combination of abrasion resistance, low-noise operation, and versatility is important. Surface material selection should take into account wear caused by carton edges and returnable containers, while matching the on-site environment.

In addition, from the perspective of improving the working environment, belts with low-noise characteristics are increasingly required.

Q. “Why is lateral rigidity important in airport baggage handling systems?”

A.　In airport applications, uneven loads and impact loads occur frequently. If lateral rigidity is insufficient, localized belt deformation can occur, leading to tracking issues and premature wear.

The structural design of Transilon provides excellent load distribution across the belt width, enabling stable conveying even in curves and transfer sections.

Q. “What technical considerations are required in food processing operations?”

A.　In food applications, cleanability, chemical resistance, and thickness uniformity are essential. Fine surface irregularities can cause residue buildup, so surface designs that take cleaning processes into account are required.

In addition, considering temperature fluctuations and the use of cleaning chemicals, selecting a belt with minimal dimensional change contributes to stable operation.

Q. “Which properties are effective in processes where water or oil is present?”

A.　When water or oil is present, the coefficient of friction can vary significantly. Therefore, friction stability under wet conditions and resistance to oil and moisture are important.

With Transilon, appropriate selection of surface materials makes it possible to minimize friction differences between dry and wet conditions.

Q. “What technical measures are required in processes where electrostatic charge is an issue?”

A.　Electrostatic charge can cause product adhesion and affect electronic components, as well as pose a risk of spark discharge. Depending on the application, it is important to select antistatic or electrically conductive belts and evaluate them in conjunction with the grounding conditions of the equipment.

Q. “Which structural characteristics are important for curved conveying?”

A.　In curved conveying, force transmission across the belt width and edge stability are critical. Depending on the belt structure, speed differences between the inner and outer edges can occur, causing mistracking and edge wear.

The structural characteristics of Transilon suppress such force imbalances and enable stable operation in curves.

Q. “What should be considered in low-temperature environments?”

A.　In low-temperature environments, material hardening can lead to bending fatigue and reduced flexibility. Material designs that maintain flexibility at low temperatures and ensure dimensional stability are essential.

Q. “Which properties are suitable for equipment using small-diameter pulleys?”

A.　For small-diameter pulleys, longitudinal flexibility and resistance to bending fatigue are important. Thanks to its thin construction and optimized tension member design, Transilon achieves long service life even under small pulley diameter conditions.

Q. “Which properties should be prioritized in highly abrasive processes?”

A.　For wear resistance, it is important not only to consider surface hardness, but also to select materials appropriate to the operating conditions. Taking into account the conveyed product shape, contact pressure, and speed, balancing abrasion resistance with running stability leads to extended belt life.

Q. “Can profiles and sidewalls be attached to all Transilon belts?”

A.　No, they cannot be attached to all Transilon belts. There are limitations depending on the belt surface coating material, thickness, and tension member structure.

In particular,
・1-ply types
・NOVO types
are not recommended for cleat attachment.

In addition, there are restrictions on cleat welding for E5/2 types, so prior confirmation is required.

Q. “Are profiles always required for inclined conveying?”

A.　Not necessarily. Depending on the type of surface pattern, inclined conveying of up to 30° may be possible without profiles.

However, depending on
・the shape of the conveyed product
・surface condition
・wet or humid environments,
using profiles and/or sidewalls in combination may provide more stable conveying.

Q. “Can the mounting angle of cross profiles be freely designed?”

A.　The standard mounting angle is 90° relative to the belt edge. Arrangements other than 90°, such as V-shaped or curved layouts, are possible, but prior consultation is required.

In particular, for V-shaped centering profiles, the angle creates clear limitations on belt width and length.

Q. “Can perforated belts be used with any drive system?”

A.　No. Since the Transilon tension member has a fabric construction, it is not suitable for sprocket drive systems.

In addition, perforated belts may have holes intersecting the splice area, therefore Step Z splicing or overlap splicing is mandatory.

Q. “What are the benefits of edge sealing?”

A.　By applying edge sealing, ・oil and grease ・bacteria and mold can be prevented from penetrating the belt, extending belt service life.

Depending on the application and belt type, either Smartseal or Proseal is selected.

Q. “What are the key points for knife-edge applications?”

A.　The most critical points are ・belt flexibility ・the splicing method.

Transilon knife-edge belts feature a special tension member structure that allows operation on knife edges with a radius as small as 3 mm.
For splicing, heat-and-pressure Z splicing is recommended.

Q. “For electrostatic protection, should antistatic or HC be selected?”

A.　This clearly depends on the application.

・Antistatic belts → suppress the generation of static electricity
・HC (high conductivity) belts → actively dissipate static electricity

When ESD protection is required, only HC belts are suitable.
