For over 40 years, AccuWeb has been the trusted leader in custom web guiding systems, helping manufacturers maintain precise web handling, improve product quality, reduce waste, and maximize production efficiency. AccuWeb’s Positive Displacement Guides (PDGs) provide the most common and accurate method of web guiding, delivering reliable alignment across converting, printing, packaging and web processing applications.

Available in economical, premium, and heavy-duty configurations, AccuWeb’s PDGs are engineered to provide fast response, reliable performance and flexible installation for virtually any web handling application. Whether you are guiding narrow web, mid-width or wide web applications, AccuWeb offers a Positive Displacement Guide Solution designed for your process.

Why use positive displacement guides?

The most accurate method of web guiding

Positive displacement guides are often the preferred solution when applications require maximum guiding accuracy and limited available web span. By moving the guide assembly rather than steering the web, PDGs provide precise correction and reliable web position control access a wide range of materials and operating conditions. 

 

Benefits

  • Precise web alignment and position control
  • Small entry and exit span requirements
  • Fast response and repeatable performance
  • Reduced waste and improved product quality
  • Flexible installation in vertical, horizontal or inverted orientations
  • Suitable for converting, printing, packaging, coating, laminating, and web processing applications

When to use a positive displacement guide

Positive displacement guides are ideal when:

  • Maximum web guiding accuracy is required
  • Available web span is limited
  • Material waste must be minimized
  • Product quality requirements are strict
  • Consistent web alignment is critical
