Feeding Systems
Feeding systems play a crucial role in the rubber and silicone processing industry, as they ensure that materials are introduced into the production systems efficiently and precisely. Our modern feeding systems enable accurate and efficient material delivery to optimize production processes and improve the quality of your products. With our reliable and durable solutions, you can save costs and shorten production times.
For feeding, materials are provided on a pallet or in a box and from there fed to the respective machines. It is important that the material supply is continuous and uniform to ensure consistently high production quality. To this end, our feeding systems are equipped with sensors and control technology to automatically monitor the process and regulate it if necessary, ensuring high process reliability and efficiency. With our wide range of automatic feeding systems, featuring control, display, and signaling of:
- Continuous belt feeding at the extruder
- End of the strip / interruption of feeding
- Strip breakage in the hopper
we offer the right feeding system for every type of packaging, material, and extruder type.
Trust in our years of experience and let our feeding systems convince you.
Piston Feeder
The Piston Feeder is specifically designed for the production and shaping of unvulcanized silicone extrusion products. It enables continuous feeding of silicone strips into a silicone extruder and is designed to be fitted directly onto the extruder.
The system features an electromechanically operated working cylinder, which enables the precise shaping of the extrusion products. An integrated, automatic conveying system, controlled by a contactless control system, dynamically adjusts the feed rate to the speed of the extruder, ensuring optimized material supply.
Mounted on a stable base plate, the piston feeder is positioned horizontally above the feed area of the extruder, allowing for a contactless and efficient transfer of material from the nozzle directly into the extruder hopper.
With its robust design and high-quality processing, the piston feeder offers reliable and powerful functionality that increases productivity. Its ease of operation further contributes to the efficiency and quality of the production processes.
Strip Feeding Device (SAV)
The strip feeding device (SAV) enables the even, continuous, and controlled withdrawal of a feeder strip from a pallet or crate to supply it tension-free to a downstream extruder. The device, which is based on the interplay of various components, is placed in front of the extruder and firmly anchored to the ground.
On the inlet side, a roller conveyor feeds the material strip, which is then passed between a drive roller and a pneumatically actuated pressure roller to ensure constant movement. The pressure roller adjusts the pressure on the strip, while a protective enclosure secures the strip feed area.
A dancer control monitors the sag of the feeder strip and regulates the speed of the drive roller accordingly. Additionally, the reaching of the strip’s end, an interruption of the strip feed, or a strip tear at the extruder intake is monitored and signaled. An optional tunnel metal detector can be used to detect metallic contaminants in the strip.
The use of strip feeding device not only increases productivity but also improves the quality of the final products. The automated handling of the material strip accelerates the processes and contributes to the minimization of errors.
Strip Feeding Device (SEV)
A strip feeding device is used to draw a feeder strip applied on a carrier film from a WigWag storage container and feed it to the subsequent extruder in a smooth, continuous, and controlled manner. The functionality is based on the fact that the film is peeled off the material strip and wound onto a driven drum.
The strip feeding device is positioned in front of the extruder so that the deflection roller of the feeding device is located above the hopper section of the extruder. The carrier film is wound onto a film drum, which is driven by a gear motor, thereby peeling the material strip from the film.
The upper pressure roller of the strip feeding device is pivotally mounted and equipped with a limit switch to signal the end of the strip. A spring-loaded dancer lever for regulating the lower roller drive ensures a defined withdrawal speed, which can be controlled by a potentiometer. The outlet roller has a standstill control and signals a strip tear in the hopper section of the extruder.
By using a strip feeding device, workflows can be optimized, production times shortened, and errors reduced.
