Web Guiding Systems and Web Guides for any Web Converting Process

Double E / Re Web Guides

"ReLink Web Guiding Systems"
All Double E / Re web guides separate the RK31 interface controller from the MWG61 driver.
This separation allows many improvements over conventional web guide systems.

One remote controller directs up to 10 web guides.
A single Serial BUS RS485 cable connecting the devices and short cables to actuators reduce electrical noise and wiring time.
24VDC power, so no UL or CSA certification is needed.

RK31 Remote Web Guide Controller
	Controls up to ten web guides simultaneously! Clear, user-friendly LCD display. Simple joystick operation. Step-by-step popup instructions in multiple languages. Compact & removable – mounts on a DIN rail; small enough to put in your pocket!
MWG61 Web Guide Driver
	Driver is packaged in one small unit which is mounted directly on the web guide frame or actuator. Disturbance is minimized because cables between the driver, motor, and all sensors are far shorter.
Brushless DC Stepper Motors
No maintenance – (no brushes). Precise web guiding control (standard = .004” = 0,1 mm). Unlike AC drive web guides, these advanced motors don’t overshoot the established set point so the web stays perfectly aligned. Set point micro-adjustment through controller. Minimized actuator work extends life.

Edge guiding, center guiding, and line guiding available with the following
Web Guide Types

Pivot Frame Web Guiding Systems Series WG
	This system utilizes two parallel rolls positioned where maximum precision is required, with the sensor placed just after the output roll. • Puts least amount of stress on the web material. • Most precise.
Shifting Actuator Web Guiding Systems Series AT
	A simple system which moves the unwind or rewind station, together with the roll, to keep the material aligned. • Thrust force up to 770 lbs (350 Kg). • Stroke distance of 2”, 4”, or 8” (50, 100, or 200 mm). • Flange or base mounting styles.
Steering Rolls Web Guiding Systems Series WR
	WR Series web guides utilize rollers which move on an arc around an ideal point of rotation, situated at the beginning of the entering span. The entering span must be long enough to ensure complete correction of the web (three to four times the maximum web width) without damaging the web material.

Web Guide Sensors and Sensor Carriers

Infrared (SIR) and Ultrasonic (SU) Sensors
	• For reading the position of the web’s edge. • Ultrasonic for opaque or transparent materials. • Infrared for materials that don’t reflect sound waves (like foam).
Optical (SL3) Sensors
	• For controlling a line, color contrast or material edge. • Reads very thin lines or threads. • Detects contrast of similar colors (ie. - white on yellow). • Sees holograms with high reflection and low contrast
Sensor Carriers
		Used when the position of the sensors is frequently moved, when access is very difficult, or if the material being guided has width variations that exceed the working range of the standard sensor. Carriers allow axial movement of sensors; controlled by the RK31.
