Gauntlet
Avoca Services Ltd has produced sewn gauntlet material for some of the world’s leading battery manufacturers for over 20 years. This operation has expanded significantly in recent years and currently has the manufacturing capacity to produce 20 million linear meters per year, making us one of Europe’s largest producers of non-woven gauntlet for the Lead Battery Industry.
We have partnered with an experienced forming machine manufacturer to provide an end to end solution for your gauntlet requirements. This has created new opportunities for growth in the industrial battery sector throughout the world. Investment in bespoke state of the art technology provides new solutions to particular specialist demands that allow our customers to have continued confidence in our product and services resulting in high repeat business.
Non-Woven Gauntlets
Avoca’s non-woven gauntlets are suitable for both wet and dry filling operations. Gauntlets are tailor-made to meet the individual requirements industry wide within the pluri-tubular positive plate retainer market.
The process to manufacture non-woven (cartridge-belt type) gauntlets consists of marrying two rolls of polyester non-woven fabric at predetermined pitches with a multi-needle sewing machine, then thermoforming the sewn roll into the desired tube geometry size. The thermoforming procedure consists of inserting forming rods between the 2 layers of sewn gauntlet fabric that pass through a hot oven to enable the forming process of the product to take place.
Non-woven gauntlets are manufactured with 100% polyester high tenacity yarn, therefore, have a reduced mechanical resistance and elasticity, a lower percentage of acrylic resin and a lower rigidity. They are recommended for industrial applications such as traction / semi-traction, flooded, Gel, and also network power application batteries.
We can supply unformed, sewn gauntlet to give your business flexibility, greater stock control and the potential to react quickly to a changing industry. We can also support your requirement for formed gauntlet by offering machinery, installation and training solutions.
Our products can be tailored to individual customer specification, variations include:
- Material weight
- Resin binder content
- Sewn pitch
- Internal diameter
- Gauntlet height and width
- Glued edge protection
- Selvedge edge, size and shape
- Tube shape
- Design
Avoca Service’s dedicated capability leads the way in development of new gauntlet material – this, aligned with the capability to design individual gauntlets ensures Avoca Services are always at the forefront of gauntlet technology.
Gauntlet Options
Tubes
Gauntlets are available in may tube shapes as illustrated. Gauntlets can be supplied with up to 30 tubes each on request. Many standard sizes are available from stock or on fast turnaround.
Avoca’s bespoke sewing technology offers flexibility, accuracy and guaranteed quality for our customers.
We can support your business from enquiry through to formed gauntlet with our partners who produce tailor-made forming machinery.
We can adjust almost all of the fabric parameters such as fabric weight and binder content to meet your individual requirements.
We can manufacture to meet your design and application requirements, offering flexibility in:
tube pitch, size, diameter(internal and external) and width
gauntlet heights and number of tubes required
selvedge size, lateral finish and edge protection
Edge Protection
Avoca are specialists in providing this particular method of gauntlet protection against short circuits.
The protection is necessary and recommended when battery manufactures choose to use veneer type separators rather than the conventional sleeves.
Protection of the outer positive plate tubes is made by applying a thin layer of sealant which acts as an insulation.
The insulated surfaces then act as a barrier between the fabric fibres and lead particles which are freely floating within the cells electrolyte.
The dimensions of the edge protection can be adjusted to match your specification.

Technical Specifications
Technical Characteristics of Avoca Gauntlets
- The nonwoven fabric structure is allow forming but to retain flexibility.
- Fast and easy filling with powder or paste through wet and dry filling.
- Low electrical resistance. Good resistance to electrochemical oxidation.
- Excellent resistance to surface abrasion due to use of high quality raw materials.
- Higher porosity of yarn density designed to achieve very even and minute holes to preserve the active mass and prevent it shedding.
- The gauntlet offers glued edge protection against plate lateral short circuits by partially coating the end tubes. This protection is an efficient and more economical alternative to the sleeve technique.
- Tubes can not only be made as round, but oval, elliptical, rectangular and square.
