Preroll Press


Every pre-roll operation runs a vibration table, a filling machine, and a tamp station — but the bottleneck that silently kills throughput sits at the very front: hand-placing 121 individual cones into a work tray, one by one, before a single gram gets packed. Preroll Press built the Fill N' Fold system specifically to eliminate that step. The Fill N' Fold Cone Loading Tool drops a complete round of cones into the tray in one clean, controlled motion — converting what was a two-minute chore into a two-second transfer. For operations running a single format, the Single Package in .5g 84mm or the Single Package in 1g 109mm delivers a purpose-matched solution, while the Double Package handles both sizes from a single kit.

Preroll Press: Complete Guide

The Front-End Fix That Multiplies Every Machine Downstream

Investing in a fast filling machine only to bottleneck it with slow tray loading is one of the most common — and most costly — inefficiencies on a pre-roll line. Preroll Press addresses the problem at its source: the moment cones go from box to tray. By standardizing that handoff with a purpose-built loading tool, every downstream step — filling, tamping, and closing — runs at full capacity instead of waiting for setup to catch up.

Why the Fill N' Fold System Outperforms Manual Loading

The structural advantage of the Fill N' Fold design comes from precision engineering applied to a task that operators typically improvise. CNC-milled structural HDPE plates and acrylic components ensure that every cone seats correctly before the release, preventing the crushed tips and misaligned papers that cause rejects and slow down packing.

  • Simultaneous 121-Cone Drop: The Fill N' Fold Cone Loading Tool releases an entire round of cones in one motion via four thumb-latches, eliminating the repetitive single-cone placement that fatigues operators across multi-shift runs.
  • Universal Format Compatibility: The included large-format extension adapts the same tool from 70mm dogwalker cones all the way through 120mm party cones — any cone with a standard 26mm filter drops straight in without additional hardware.
  • Made-in-USA Durability: Structural HDPE resists the mechanical fatigue that causes cheaper plastic loaders to warp and stick, maintaining consistent snap-and-release precision across three-shift commercial schedules.

Choosing the Right Fill N' Fold Format for Your Run

The Fill N' Fold system is available in three distinct configurations — the right choice depends on which cone formats the operation runs and how frequently it switches between them.

  • Single-Format .5g Runs (84mm): The Fill N' Fold Single Package in .5g 84mm is designed for operations producing standard half-gram pre-rolls. It pairs directly with any vibration-based filling table and delivers a precision drop for every cycle on a dedicated 84mm line.
  • King-Size 1g Runs (109mm): The Fill N' Fold Single Package in 1g 109mm serves operations producing king-size product exclusively. The format-specific sizing ensures cones seat and drop cleanly without the tip-crush risk that comes from using an ill-fitting loader on longer papers.
  • Mixed-Format or Multi-SKU Lines: The Fill N' Fold Double Package handles both 84mm and 109mm formats from a single kit, reducing equipment footprint and eliminating changeover time for operations that run multiple SKUs. Rather than maintaining two separate loading tools, one Double Package covers the full format range.

Maximizing Throughput With the Fill N' Fold on a Live Production Line

The Fill N' Fold is straightforward by design, but a few operational habits ensure it performs at its ceiling across every shift.

  • Practice the Release Before the First Run: Run several dry drop cycles — without cones — to dial in the thumb-latch motion before loading product. A clean, level release is the difference between a perfect 121-cone drop and a tip-crush event that requires resetting the tray.
  • Use the Included Stand Between Batches: The dedicated stand keeps the tool upright and off the packing table between cycles, preventing slide mechanism contamination from surface residue and keeping the workspace clear for the next fill step.
  • Clean Between Strain Changes: The smooth acrylic and HDPE surfaces wipe down in seconds. Cleaning between strains prevents sticky resin buildup in the slider channels — which is the most common cause of uneven cone seating on high-cycle runs.

Pairing proper loading technique with the right downstream equipment keeps the entire pre-roll line producing at capacity rather than idling at setup.

Frequently Asked Questions

What exactly does the Preroll Press Fill N' Fold Cone Loading Tool do?
The Fill N' Fold Cone Loading Tool loads up to 121 pre-rolled cones simultaneously into the Fill N' Fold Work Tray in a single motion. Operators place cones into the HDPE loader, engage the four thumb-latches to secure them, position the tool over the tray, and release — dropping all 121 cones cleanly and evenly at once. It eliminates the manual single-cone placement step that creates the primary throughput bottleneck at the start of every filling cycle.
What cone sizes does the Fill N' Fold system support?
The Fill N' Fold system supports any pre-rolled cone with a standard 26mm filter, spanning sizes from 70mm dogwalkers up through 120mm party cones. The Single Package in .5g 84mm is matched to standard half-gram production, while the Single Package in 1g 109mm is configured for king-size runs. The included large-format extension adapts the base tool for 109mm and 120mm cones, and the adjustable sliders ensure papers seat securely regardless of cone length.
What is the difference between the Single Package and the Double Package?
The Single Package comes configured for one cone format — either the .5g 84mm or the 1g 109mm size. The Double Package includes both configurations, allowing a production line to switch between standard half-gram and king-size runs without purchasing or managing two separate loading tools. Operations that run a single SKU benefit from a Single Package, while those with mixed-format production get the most value from the Double Package.
Does the Fill N' Fold work with any vibration table or filling machine?
Yes. The Fill N' Fold loads cones into the Work Tray — from there, the tray feeds any vibration-table-based filling system. It is not exclusive to a specific brand of filling machine. Any vibration filling setup that accepts a standard loaded tray functions as a direct downstream partner to the Fill N' Fold.
Can the Fill N' Fold handle the pace of a multi-shift commercial operation?
The structural HDPE plates are designed to withstand continuous use across three-shift production schedules. Unlike cheaper injection-molded plastic loaders, the CNC-milled construction maintains its dimensional accuracy over high cycle counts, preventing the warping and sticking that degrades loading precision and forces operators to reset the tray mid-run. Every Fill N' Fold unit is made in the USA and built to commercial production standards.
How do you clean the Fill N' Fold between strain changes or shifts?
The smooth acrylic and HDPE contact surfaces wipe clean in seconds. Resin buildup in the slider channels is the primary cause of uneven cone seating, so wiping the mechanism down between strain changes maintains consistent drop quality. No disassembly is required for routine cleaning — the design intentionally avoids small joints and recesses where debris accumulates.
Which Fill N' Fold package is right for a line that runs both 84mm and 109mm cones?
The Fill N' Fold Double Package is the direct solution for mixed-format lines. It includes both the 84mm and 109mm configurations in a single kit, eliminating the need to purchase and store two separate tools. Format changeovers require no additional hardware — the included extension and adjustable sliders handle the transition between sizes.
Where does the Fill N' Fold fit in a complete pre-roll production workflow?
The Fill N' Fold sits at the front of the packing line, immediately before the vibration filling step. The standard workflow runs: (1) Load cones into the tray via the Fill N' Fold, (2) fill and settle material using a vibration table, (3) tamp to finished density, (4) close and seal. By removing manual tray loading from step one, the Fill N' Fold ensures the filling machine never idles waiting for setup.
