AccuWeb shifting base guide assemblies
Precise unwind and rewind web handling for improved roll quality and web alignment
Unlike intermediate web guiding systems that correct web position within the process, Shifting Base Guide Assemblies control web alignment directly at the unwind or rewind stand, helping prevent roll-related issues before they impact production. These custom-engineered systems are designed for reliable operation in even the most demanding production environments.
Why use a shifting base guide assembly?
Improve roll quality and maintain accurate web alignment
Shifting base guide assemblies maintain web position by moving the entire unwind or rewind roll. This approach helps maintain consistent edge position, improve roll quality, and eliminate alignment issues before they impact downstream processes. Unlike intermediate web guides, shifting base systems control web position directly at the unwind or rewind stand, providing precise correction where it matters most.
Benefits:
- Precise unwind and rewind web position control
- Improved roll quality and edge alignment
- Elimination of telescoped and uneven rolls
- Reliable web alignment throughout entire production
- Custom-engineered solutions for virtually any application
When to use a shifting base guide assembly
Shifting base guide assemblies are ideal when web position must be controlled directly at the unwind or rewind stand. They are particularly effective for improving roll quality, eliminating roll defects, and maintaining accurate edge alignment throughout the production process.
Consider a shifting base guide assembly when:
- Roll quality is critical
- Telescoped rolls are causing production issues
- Web alignment must be controlled at the unwind
- Precise rewind edge alignment is required
- Oscillation is needed to reduce gauge banding
- Large or heavy rolls require accurate positioning
Engineered for your process

SR-AP series
Lightweight performance for narrow and mid-width webs
The SB-AP series utilizes anodized aluminum plate construction to provide a high strength-to-weight ratio and fast response for narrow and mid-width web applications. Smooth surfaces and corrosion-resistant materials make the AP Series ideal for cleanroom and hygienic production environments.
Best for
- Flexible packaging
- Film converting
- Label production
- Coating and laminating
- Cleanroom environments
SR-FS series
Heavy-duty guiding for wide web applications
The SB-FS series uses structural steel tube construction to deliver exceptional strength and design flexibility for wide-web and high-tension applications. These systems are custom engineered to integrate with unwind and rewind stands while providing reliable long-term operation.
Best for
- Paper converting
- Wide-web processing
- High-tension applications
- Corrugated production
- Heavy industrial environments
