Belts woven of polyester and polyamide, as well as other polymeric materials.
It's all in the mix: polyamide and polyester for abrasive applications
GKD Thermoplastic Process Belts are utilized in nearly all industries throughout a broad range of application such as Belt Presses, Belt Filters, Dryers, Vacuum Belt Filters, Pan Filters, Textile Treating Machines, Nowoven Production and Drum Filters. For these applications GKD is a leader in the development and production of standard and specialized ready-made Filter Belts and Linear Screens. Technical data on the most commonly used styles can be found on the following pages and further information on specialized types is also available upon request.
GKD Thermoplastic Process Belts are typically manufactured from polyester but can also be made with special materials such as polyamide, PPS and PEEK. Our Thermoplastic Process Belts are made on strong weaving looms, typically associated with metal belts, giving them incomparable stability. Subsequent thermal treatment provides consistency in aperture and offers improved performance and belt life in applications with elevated temperatures. The possibilities of different mesh constructions, weave patterns, wire diameters, material, mesh openings and air permeablilty are virtually endless.
GKD supplies Process Belts that are individually suited to specific applications, depending on the type of process, product, air permeability and chemical and thermal conditions. Our broad product range of Process Belts covers almost every application, but if your application requires special attention, we have the experience and knowledge to develop a process-specific belt.
Plain weave/Linear screen One warp wire is bound over one weft wire respectively and vice versa. This is the classic weave pattern with good binding and exact square, longitudinal or wide mesh.
Twill weave One weft wire is bound over at least 2 weft wires and vice versa. This results in a smooth surface and good belt run characteristics. For example type 1003, 2045 and some meshes for the nonwovens production as no. 8/7 p.cm are woven in this weave pattern.
5-heddle weave (Tela) This 5-heddle mesh is an advanced form of the twill weave, usually with a 3/2 binding. This means an even flatter smoother surface for a good cake-building and discharge as well as a more robust running side besides good belt running characteristics, e.g. type 5060, 5090 and 5080.
6-heddle mesh A special binding 4/2 usually combined with fine wires. It is distinguished by its smooth surface and finest apertures, e.g. type 7280.
8-heddle weave This 6/2 binding allows for an even smoother surface. It's often called satin weave. It can be found in our 8-heddle meshes type 8050, 8060 and 8065.
Apart from this standard weave patterns special patterns can also be realized
Double layer weaves Double layer weaves provide for the surface characteristics, flow, tortuous path, and allow for a non marking recessed pin seam to make the belt endless.
Thermoplastic Belt Edges
Typically GKD Thermoplastic Process Belts are supplied with heat-cut and sealed edges. This process secures the edges and keeps them from unravelling, ensuring extra belt durability. In addition, edges can be coated with synthetic resins, offering additional protection for problem processes. We also can affix round plastic elements allowing the belt to be guided in U- profiles.
Thermoplastics Belt Seams
Hook seams made of stainless steel are specifically tailored based on the application and process and are stabilized with special coatings. If necessary we can provide hook seams without any additional coatings.
The benefits of GKD hook seams are:
Quick and simple installation
Pin wires are supplied as monofilaments and can also be supplied in flexible construction.
Specialized seams for sensitive applications and products can be supplied in the following:
Non-marking endless woven seams
Nearly non-marking woven pin seams
Flexible hand-sewn pin seams made either of plastic or metal
