Feed one sheet through a pair of rollers and reveal its original edge

Original, untested video brief. No input image or generated result is supplied.

1. Task and boundary

The task begins with the leading edge of one sheet already just inside the narrow passage between two rollers. Their contact surfaces move together toward frame right, pulling the sheet through. The original leading edge then emerges on the far side, followed by an identifying stripe already present on the sheet. The key evidence is entry, hidden passage and reappearance belonging to one continuous sheet, rather than a new rectangle appearing beyond the rollers.

Use a short, flat feed with one sheet and no folds, printing or cutting. The rollers rotate about fixed centers while the sheet translates. They do not travel across the table like wheels. Starting with the edge captured avoids claiming that rotating rollers can pull a distant, noncontact sheet into the nip. No exact feed speed, traction coefficient or industrial performance is inferred.

2. Authorized first frame

Prepare an original side-oblique diagram or an authorized photograph. Show two equal-size plain rollers stacked vertically, with their parallel axes pointing into the scene. Place a flat sheet on a fixed guide table entering from the left. Its original leading edge is already just inside the nip and has not yet emerged on the right. Put a broad colored stripe a short distance behind that edge, still visible on the incoming sheet.

Include recognizable rim marks on both rollers and visible fixed bearing supports. Show the sheet width in the oblique view, leaving enough open space at the right for the same leading edge and stripe to emerge. Give the sheet a contrasting edge so it does not blend into the guide table. The roller contact gap should accommodate the thin sheet; do not draw two overlapping solid cylinders. Avoid logos, unreadable small text or a housing that hides both sides of the passage.

3. Use the generator

Open the current image-to-video generator in a mode accepting your authorized first frame. Paste the complete prompt, check the available settings and cost estimate, then submit only when ready. This page supplies text; it does not upload an image or start a generation.

4. Prompt and timing

Use the supplied first frame. Keep both roller axes, bearing supports, guide table and camera fixed. Turn the upper roller counterclockwise and the lower roller clockwise in the displayed side view, so both facing surfaces move toward frame right through the nip. Feed the single sheet that is already engaged between them. Preserve the sheet width, thickness impression, original leading edge and identifying stripe. Let the original edge emerge on the right before the stripe follows through the same passage. The left visible portion becomes shorter as the right visible portion becomes longer. Keep the sheet flat and supported, with no tearing, folding or added sheet. Do not let the rollers translate or rotate together in the same direction. Slow the feed and stop with the stripe visible beyond the nip and part of the original sheet still on the incoming side. Hold without reversing.

1. Opening: identify the captured leading edge, the stripe behind it, both marked roller rims and the fixed supports. The sheet is already in contact before powered feed begins.
2. Middle: follow the two opposite rotations and the shared rightward surface motion at the nip. Observe the original edge emerge first, then the original stripe, preserving their order.
3. Ending: stop after the stripe has cleared the nip while a visible incoming portion remains. Keep both rollers and the sheet stopped together without a second feeding cycle.

These beats are author suggestions, not exact model timing guarantees. Adapt their proportions to the clip length actually available.

5. Inspect the output

After inspecting your own output, record a time or frame, visible observation and pass, fail or inconclusive judgment for each condition. A convincing ending alone does not verify the preceding action.

• The two roller centers remain fixed, with upper counterclockwise and lower clockwise rotation in the displayed side view.
• The facing surfaces at the nip move in the same rightward direction as the sheet, rather than fighting one another or sliding backward through it.
• The original leading edge appears on the right before the identifying stripe, with their order and spacing remaining coherent.
• The incoming visible sheet becomes shorter while the outgoing part grows; the two regions remain connected through the same narrow passage.
• The sheet retains its width and flat form without duplication, unexplained folds or tearing, and stops with material still visible on both sides.
• If the edge or stripe cannot be tracked across the hidden passage, record inconclusive; two similar rectangles on opposite sides are insufficient proof of one-sheet feeding.

6. Fix one failure

• If both rollers turn the same way, describe the direction of each separately and emphasize the shared rightward motion of their facing surfaces.
• If the sheet starts moving before contact, move its initial leading edge into the nip in the authorized input. Do not add an unexplained attracting force.
• If a new sheet appears at the exit, enlarge the existing stripe and shorten the feed. Require the original edge first and stripe second as a visible identity sequence.
• If the rollers roll across the table, make the bearing blocks prominent and freeze their centers. The shaft marks should rotate while the supports remain fixed.
• If the sheet buckles or tears, reduce the requested travel and keep a simple support table. Change one instruction and reinspect the full entry-to-exit path.

7. Ending and limits

The endpoint shows one sheet spanning both sides of the fixed nip, with its original stripe now visible on the right. This is a short feed demonstration, not a full-sheet discharge. Keep the inspection focused on the marker crossing and the opposite roller rotations rather than the apparent neatness of the final page.

Save your own generated result through the available result controls, together with the authorized input, exact prompt, settings and inspection notes.

No generated example, real roller trial or measured slip is supplied. Hidden contact can be imitated by texture animation, and the visible result cannot establish feed accuracy or reliability under another material. Save the authorized source, prompt and observations, and mark uncertain identity through the passage as inconclusive.

The conveyor task carries a parcel on a translating support surface. Here two rotating surfaces meet at a fixed nip and pull a flexible sheet through it. Unlike the auger proposal, there is no helical flight or granular rearrangement; the essential event is one marked sheet crossing a two-sided contact passage.
