Increasing production speeds and rising quality demands –
modern production machines for the processing and finishing of web-type materials are used in the printing industry at speeds that were considered extraordinary only a few years ago. At the same time, suppliers in the printing industry can only remain competitive with reliable, accurate results.
The challenge: Suppliers must take full advantage of machine speeds and simultaneously guarantee that everything runs in regulated webs – from the unwinding of the materials, to the guiding, to the production process, to the winding.
Continuous and precise web guidance: BST systems regulate the web run in the most varied production processes, such as in the paper, film, foil, and rubber industries and in conveyor and transport systems. There, BST web guiding ensures that the material being processed is exactly at its intended position. BST web guiding can be used for a wide range of substrates and effectively minimize waste and downtime.
BST guiding devices correct the position of the web precisely and almost without delay, and therefore make an important contribution to smooth process sequences. Our guiding devices are deliverable in various sizes and types for almost all web widths and areas of application.
Through a target-performance comparison, BST controllers ensure that the material being processed is exactly at its intended position. The compact device design allows for the direct attachment to or in the guiding device or the machine. With a number of components that can be connected, the controllers can be optimally adapted to their respective tasks.
All BST systems for web guiding are based on a simple, closed control circuit. The current position of the web serves as the starting point. It is recorded as the current position by one or more sensors and transmitted to the controller.
Electromechanical actuators from BST are used when very fast reactions to changes in the web position are necessary. The plug-and-go design of the actuators allows for quick and inexpensive assembly, which is also beneficial in the retrofit of existing systems.
AccuWeb is known for its edge sensors, which work with the help of patented ambient compensation. The digital AccuWeb controllers were specially developed for sophisticated applications. AccuWeb controllers are available in various sizes and speeds and designs for loads of up to 50,000 kg (100,000 lbs.).
In their extent and degree of automation, BST web guiding systems always conform precisely to the demands of their production processes. The variety of connected BST components guarantees an optimal adjustment to the requirements of the specific task.
