Automatic Top & Bottom Labelling Machine should be selected around product handling, label roll data, required label position and the real production speed needed after changeover. A good specification should also confirm operator access, cleaning, guarding, conveyors, coding and spare parts before the machine is ordered.
Send your sample details, label roll specification and required output. Lancing UK can advise whether this configuration is suitable or whether another labelling route would be better.
Top-and-bottom labelling is used where both faces of a carton, tray, card, sleeve or other flat product need labels in one production pass. The lower label head normally needs access through a controlled conveyor transfer. Product length, rigidity, thickness and centre of gravity therefore determine whether the pack can bridge the opening without tipping, flexing or changing position.
The product is detected and transported across the application area while the upper and lower label heads dispense at defined positions. The top label can be applied against a supported conveyor surface, while the bottom application depends on the transfer geometry and support before and after the peel point. Both heads need independent label-roll setup, sensing and timing, but the product path must keep the pack in the same lateral position for both faces.
Use a single top or side applicator when only one face needs a label. A print-and-apply system may be more suitable where the label content is generated at the point of application, and front/back equipment may be preferable for upright bottles rather than flat packs.
Unknown values should be confirmed from the real product and label rather than replaced with catalogue assumptions.
| Product support | Minimum and maximum length, width and thickness, rigidity, filled weight, centre of gravity, feet, recesses, seals and any flexible region that cannot bridge a conveyor gap. |
|---|---|
| Upper and lower labels | Dimensions, materials, gaps, cores, outside roll diameters and unwind direction for both rolls, including whether their positions must align through the pack. |
| Placement references | Leading edge, side datum and allowed label area on each face. Supply marked samples or artwork where labels must avoid windows, seams or printed information. |
| Line conditions | Product spacing, incoming and outgoing conveyor details, normal rate, stop-start behaviour, coding or inspection equipment, guarding and access below the conveyor. |
Test the shortest, longest, lightest and most flexible agreed products, not only the most stable format. Check that each pack crosses the lower-head transfer without pitching or changing its side datum. Inspect top and bottom placement separately, then confirm any required relationship between the two labels. Repeat after a changeover and after several stops and starts if that reflects normal production.
Clean peel edges, rollers, belts and sensors on both label paths. Inspect conveyor transfers for debris, wear and changes in belt tracking. Because the lower head is less visible, include it in routine roll-threading and adhesive-build-up checks rather than adjusting timing from the top of the machine only. Record upper and lower settings separately for each SKU.
Include upstream and downstream equipment, conveyor direction and height, normal stops, operator access, utilities and any control signals. State which items are essential and which are future options.
Flat, sufficiently rigid products such as cartons, trays, cards and sleeved packs are typical. The product must remain controlled while the underside is exposed to the lower label head.
The pack may need to bridge a conveyor transfer used to access the underside. A product that is too short or flexible can tip, sag or lose its reference position.
Only if the pack design requires it. Define separate references for both faces and state any relationship that must be maintained between the two labels.
Clear labels may require suitable sensing and should be tested with the actual label and liner on each head.
Send the extremes of the product range, normal production label rolls, marked placement examples and details of the incoming and outgoing conveyor arrangement.
Use a single top applicator when only the upper face needs a label and the product can be presented consistently without a lower-head conveyor transfer.
Send product samples or dimensions, the label-roll specification, marked placement examples, normal output and the surrounding line details.
A top-and-bottom system must expose two product faces while keeping the pack on a repeatable path. Pack rigidity, thickness, leading edge and the support available during transfer can be more important than the nominal capability of either label head.
Flexible pouches, bowed cartons, trays with rims and products with an uneven underside can respond differently to guides and wipe-down pressure. Test the production condition, not an empty or specially selected sample.
Confirm how the pack crosses the opening or split needed to reach the underside. The product must not dip, rotate or change speed in a way that moves the bottom label reference.
Top and underside labels can have different dimensions, gaps or materials. Provide both production rolls and define which product trigger controls each application event.
| Test condition | Top-face check | Underside check |
|---|---|---|
| Smallest and thinnest pack | Trigger point, wipe-down and label overhang | Support across transfer and repeatable leading edge |
| Largest or least rigid pack | Guide clearance and surface contact | Deflection, tracking and clearance around the lower head |
| Representative sequence | Position after several products and after a short stop | Position after transfer and at normal product spacing |
| Changeover | Head, guide and sensor settings restored | Transfer and lower-head settings restored |
| Fault recovery | Known status of the upper label and product | Known status of the lower label before restart |
The page clip shows the upper label head, product trigger area and conveyor presentation on the automatic labeller. It helps explain the upper application stage, but it does not show the complete underside transfer. The lower application path, pack support and final two-face result should therefore be confirmed separately during the project trial.
Use the top and bottom range for the full category, the flat-surface range for single-face applications, and the flat-product guide when deciding whether a second label head is required.
Send representative packs, both label rolls, marked top and underside positions, pack orientation and the required line interface.
The smallest and most flexible products should remain supported as they cross the bottom-application opening. Test top and bottom label position, product speed through the transfer and behaviour when the line stops with a product in the labelling zone.
| Test condition | What to prove |
|---|---|
| Minimum length | Bridges the split without tipping |
| Flexible pack | Remains flat enough for repeatable application |
| Bottom surface | Adhesion across seams, recesses or contamination |
| Blocked outfeed | Controlled stop without trapped unknown product |
| Restart sample | Both labels present and correctly related |

Send the minimum, maximum and most difficult products with production-quality label rolls and the intended placement reference.
Applying a label to the underside creates a transfer and support problem as well as a label-dispensing task.
The product must bridge or pass through a controlled transfer that exposes the underside without losing position. Belt layout, product length, stiffness, weight distribution and surface contact determine whether the pack remains stable across that gap.
The smallest and most flexible intended format should be included in the transfer trial.
Flexible packs can bow, flutter or change thickness as they transfer between conveyors. Air trapped in a pouch and uneven product distribution can also shift the surface presented to the label head.
Feed method, support, belt speed and pack condition should be assessed together rather than treating the pouch as a flat rigid object.
A further applicator may be added when the product can be presented to the required closure or panel and the line has enough controlled space. The extra label introduces another roll, trigger, placement datum and missing-label condition that must be included in the controls and test plan.
Confirm whether the security label is part of the top, bottom or a separate side application.
Measure both labels from stable product edges or printed features that remain visible after the product leaves the transfer. The reference should not depend on the temporary belt gap or a moving machine component.
Where relative alignment matters, define the permitted relationship between the two labels as well as the position of each label.
Send the product, label and line details to Lancing so the answer can be checked against the real pack rather than treated as a generic machine assumption.
The smallest, lightest and most flexible product should be tested across the split or gap used for bottom application. The line layout must also retain product tracking for top/bottom inspection and reject handling.
