For quotation: system, measuring range, web width.

Positioning and follow-up control

The ELPOSER system holds the position of squeegees, suction nozzles, cutting blades and marking devices relative to the web edge: sensor and tool are mounted together on a linear guide, the measured position is compared with the setpoint and a correction signal is output.

ELFEED positions selvedges on stenter infeed, TrimMaster follows the slitter-scorer. Linear guides: VSB50, VSB60. Units: VGB14, VGB15. For tires: EL-PAPS ink bottle positioning.

For quotation: system, travel stroke, tool type.

Cleaning, cutting and infeed elements

Auxiliary line systems include web cleaning, cutting devices and infeed elements. ELCLEAN removes dust by blowers and vacuum from one or both web sides without disturbing guiding or tension control.

ELCUT covers edge trimming and slitting, while ELFEED selvedge openers spread the edge before the stenter. ELCLEAN: contact and contactless cleaning, type WCD. ELCUT: BTB01, BTA02, BTA25, BTA80. Selvedge openers: LA 82/83/84 motorized, LS 30/32/36 mechanical, LP 03 pneumatic.

For quotation: web width, material, cutting method.

Selecting equipment for your task

Selection starts with the material and web width, line speed and required edge guiding accuracy. Next comes the mounting position — infeed, middle of the line or outfeed — and only then the frame, sensor and drive type.

E+L designations combine the system type and the unit version, so one family appears on different lines in different configurations. Inputs needed: material and web width, line speed, required accuracy, mounting position, supply voltage and the way the system communicates with the line controller.

Attach a line diagram and a photo of the installed unit.

Modernization and legacy lines

Web guiding and tension control systems run on production lines for decades, and some designations are no longer manufactured. Such units are selected by application parameters: measuring range, web width, supply voltage and mounting type.

Modernization returns current units and controller communication to the line. The manufacturer provides service packages, returns and repair, plus the My E+L portal for orders and documents. For a discontinued unit, provide dimensions, mounting dimensions, connector type and operating conditions.

For quotation: dimensions, mounting dimensions, connector type.

Manufacturer and product areas

Erhardt+Leimer (E+L) is a German manufacturer of systems for production on moving webs: web guiding, web tension control and web inspection. The company was founded in 1919; the group is headquartered in Stadtbergen near Augsburg, with sites and service teams in Europe, America and Asia.

Applications cover textiles and nonwovens, printing, corrugated board, paper, film, tires and rubber, hygiene products and battery production.

ELGUIDER web guiding

Web guiding systems hold the web edge or centre line through the process. The ELGUIDER family covers pivoting frames, steering rollers, turning bars and winding stations, with dedicated versions and designations for tire, textile and corrugated board production.

Selection starts with web width, line speed and the required edge guiding accuracy.

Edge sensors and cameras

An edge sensor detects the web edge or a printed mark and sends the signal to a controller that shifts the frame or roller.

Ultrasonic sensors work on the edge, infrared sensors use retro-reflection, wide band sensors cover a large displacement range, and the colour line sensor follows a printed line. Cameras handle edge detection, positioning and width measurement.

ELTENS tension control

The ELTENS system measures and controls web tension and is configured for each line from load cells, amplifiers and control units.

Load cells differ by measuring range, housing material and mounting type; amplifiers are analog or digital, and communication with the line controller runs over an analog signal or a network interface.

EL.MOTION drives

EL.MOTION drive units are built on brushless synchronous motors and are used in web guiding, positioning and follow-up control systems. Linear versions deliver 250 to 10,000 N at 24 V, rotary versions 1.0 to 4.0 N·m, and a STO safety variant is available.

ELSCAN and SMARTSCAN inspection

Inspection technology monitors print, surface and foreign inclusions. ELSCAN handles web monitoring, SMARTSCAN print inspection, ELSIS surface inspection of film and paper, ELMETA metal detection, and ELSEAMTEX optical AI sensors.

Systems differ by number of cameras, resolution and mounting position on the line.

ELTIM measuring technology

ELTIM uses ultrasonic technology for non-contact inline basis weight measurement and derives thickness from the material density entered. Systems come with a traversing sensor head or with heads across the full web width.

ELMAT controls stenters and dryers, ELCOUNT counts picks and courses, and EL-TRISCAN measures the profile.

Modernization and service

Web guiding and tension control systems run on lines for decades, and some designations are no longer manufactured: such units are selected by application parameters, and modernization returns current drives, electronics and controller communication to the line.

The manufacturer provides service packages, returns and repair, plus the My E+L portal for orders and documents.
