Selection guide
Choose a web guide in five steps
Work through these in order. Each answer narrows the next. If you get stuck on any step, send us what you have and we will complete the selection.
01
Material → sensor
What the web is made of decides how its edge can be detected.
| Material | Recommended | Why |
|---|---|---|
| Transparent film | EDS-02 | Infrared light passes through the web, so there is no usable edge signal. |
| Paper, opaque web | EDS-02 / EDR-02 | Both principles detect the edge reliably. |
| Highly reflective foil | EDS-02 | Specular reflection can blind an infrared sensor. |
| Textile, nonwoven, mesh | EDR-02 | Ultrasound passes through porous material. |
| Printed pattern | EDV-01 | Tracks the printed line, not the physical edge. |
Guiding on the web centre? Use two sensors, one at each edge. Sensor data →
02
Position on the line → system type
| Where the guide goes | System | What moves |
|---|---|---|
| Unwind stand | TF series | The whole unwind stand moves under the roll. |
| Rewind stand | TF series | The winding stand follows the web edge. |
| Between process units | C / FTK frame | A two-roller frame steers the running web. |
03
Web width → frame
For guides between process units.
| Web width | Frame | Roller Ø | Roller span |
|---|---|---|---|
| 200 – 300 mm | All-in-one C series | 60 mm | 250 mm |
| 350 – 500 mm | All-in-one C series | 60 mm | 300 mm |
| 550 – 650 mm | All-in-one C series | 60 mm | 350 mm |
| 700 – 750 mm | All-in-one C series | 75 mm | 350 mm |
| > 750 mm | Split FTK series | Built to order | |
A split frame also suits narrower webs where the machine has no room for the all-in-one unit. Split frames →
04
Correction travel → actuator
For unwind and rewind systems. Pick the travel that covers the worst roll run-out with margin.
| Actuator | Travel | Thrust | System |
|---|---|---|---|
| WU2000-50 | ±25 mm | 2500 N | TF50 |
| WU2000-100 | ±50 mm | 2500 N | TF100 |
| WU2000-150 | ±75 mm | 2500 N | TF150 |
| WU2000-200 | ±100 mm | 2500 N | TF200 |
| WU2000-260 | ±130 mm | 2500 N | TF260 |
05
Operator interface → controller
Colour display, keys
48 MHz, 240 W drive output, 24 V DC. Standard on all-in-one frames.
Colour touch screen
240 MHz, 360 W drive output, 24 – 36 V DC. Standard on TF systems.
