The Graco PC-8e InvisiPac Pattern Controller is a hot melt adhesive pattern control system designed to work with InvisiPac equipment (or as an external standalone unit for non-InvisiPac applications). It uses a color LCD interface to let operators create, preview and switch adhesive patterns, such as solid bead or stitched bead, without manual re-tooling, reducing adhesive waste and material costs.

The PC-8e is available in the following configurations:

• Time mode or Distance mode pattern control
• With encoder or without encoder
• Optional run-up control

This flexibility allows the PC-8e to be matched to the exact line speed, adhesive pattern and automation requirements of a specific packaging or assembly application.

Key Features & Benefits

• Solid-to-stitched bead conversion at the push of a button – Reduce adhesive consumption and material spend by switching pattern types instantly, without hardware changes.
• Color LCD interface – An intuitive, easy-to-learn touchscreen-style display simplifies setup, operation and pattern changes for operators of any experience level.
• On-screen pattern preview – View the adhesive pattern before it run, eliminating trial-and-error and reducing startup scrap.
• Time or Distance mode operation – Choose time-based pattern control for fixed-speed lines or distance-based (encoder) control for lines with variable speed to maintain consistent pattern placement.
• Optional encoder input – Enables distance-based pattern accuracy that automatically compensates for line speed changes.
• Optional run-up control – Helps manage adhesive output during machine acceleration/deceleration for cleaner pattern starts and stops.
• LineSite™ Remote Monitoring compatible – Integrates with Graco’s LineSite™ Remote Monitoring Solution for real-time visibility into adhesive usage, system status and process control across the production line.
• Standalone external operation – Can be used independently of an InvisiPac melter-applicator system for applications that need pattern control without a full InvisiPac setup.

Ideal Applications

The PC-8e Pattern Controller is used in hot melt adhesive bonding and packaging lines where precise, repeatable bead patterns are required, including:

• Case and carton sealing
• Packaging and bag-making lines
• Product assembly bonding
• Any line requiring quick switching between solid and stitched adhesive patterns to reduce material cost
