Buying a flatbed applicator usually starts with a question about quality, and ends with a decision about length. That is not laziness — it is the only axis that actually changes between these three models. If you are comparing the LF1732-B4, the LF1736-B4 and the LF1740-B4, the specifications below are the entire difference.
Every figure in this table is a published machine specification, not a sales estimate. All three use the same pneumatic roller lift, the same 130 mm upper roller and the same 50 mm maximum substrate thickness, so material handling behaviour is identical. What changes is how much panel you can feed in one pass, and how much floor the machine occupies.

Pull the last 50 jobs from your production sheet and find the longest panel you run at least once a week. Specify to that length. Not to the longest panel you have ever quoted, and not to a brochure size — to the weekly reality.
Why weekly? Because a machine that is 200 mm short of your regular job does not cost you 200 mm — it costs you a seam on every panel. You either splice two pieces and accept a visible joint across a sign face, or you send the job out. Both options are more expensive than the length upgrade.
For most sign shops in the 1.52 m film market, the weekly reality lands in two buckets: rigid sheets up to 3,000 mm, and 3,000–4,000 mm panels cut from 4 × 8 ft or 5 × 10 ft stock. The LF1732-B4 covers the first bucket. The LF1740-B4 covers the second with margin.
This is the single most common source of order errors in this product category, including in published specifications.
On the LF1732-B4, the maximum lamination area is 1600 × 3000 mm. The table is 1700 × 3200 mm. The table is deliberately 100 mm wider and 200 mm longer than the lamination area — that margin is where the film tail, the clamping edge and your hands sit. The same 100 × 200 mm margin exists on the LF1736-B4 (1700 × 3600 mm table against a 1600 × 3200 mm lamination area) and on the LF1740-B4 (1700 × 4200 mm against 1600 × 4000 mm).
If a supplier quotes you a machine by its table size and calls it lamination size, a 3.2 m panel will not fit a machine sold as “3.2 m”. Ask for the maximum lamination length in writing, separately from the table dimensions.
Length does not only decide what fits. It decides how many panels leave the table per shift, because every panel that needs a join needs a second pass, a second alignment and a trim. A simple working formula:
Panels per shift = available minutes ÷ (load + pass + unload and trim + inspection)
Take a shop with 7 productive hours (420 minutes). On a 3,000 mm table with a 3,000 mm panel, a typical cycle is roughly 4 minutes to lay and align the substrate, 2–3 minutes for the lamination pass, and 3 minutes to unload and trim — about 10 minutes per panel, or roughly 40 panels per shift. Push a 4,000 mm job onto that table and you split it: one extra join, one extra alignment, one extra trim, plus the inspection time to sign off a visible seam. In practice that is 6–8 additional minutes on every single panel, and the joined panel still sells at a discount.
Treat these cycle times as a planning template, not a measurement. Time three of your own real panels before you commit — the ratio between the three models will hold even if your absolute minutes differ.
The working footprint grows by 210 mm from the LF1732-B4 to the LF1736-B4, and by another 400 mm to the LF1740-B4 (3890 → 4100 → 4500 mm long, all 2030 mm wide, 1235 mm high). That is before you add the operator zone.
If your weekly work regularly exceeds 4,000 mm, the correct answer is the LF1750-B4 (1600 × 5000 mm), not a workaround on a 4 m table. If your panels are consistent but your substrate is unusual — very thick composites, or a fixed jig requirement — the custom-size programme exists for that case and should be quoted from a drawing rather than from a catalogue.
Most sizing conversations waste a week because the buyer and the supplier are working from different assumptions. Bring these five numbers to the first conversation and the model usually picks itself:
With those five, the difference between a 3,000 mm and a 4,000 mm table stops being a preference and becomes arithmetic.
No. Its maximum lamination length is 3,000 mm. The 3,200 mm figure you may see in some listings is the table length, which includes the clamping and film-tail margin — it is not usable lamination area.
No. All three are 1600 mm (62.99″) wide, which takes a full 1.52 m roll of cast or calendered film with margin for edge trim. Width is not a decision variable here.
Yes — 50 mm (1.96″) maximum on all three. If you are laminating thick composite panels or foam board beyond that, tell us the thickness at the quoting stage; it changes the machine configuration, not just the length.
Plan from the working size plus an operator zone on the loading and unloading sides. The machines themselves are 2030 mm wide and 1235 mm high; length is 3890 mm, 4100 mm or 4500 mm depending on the model.
Yes. Send the panel size, substrate type, film type and a photo of your workshop, and we will return a size recommendation plus video of the matching machine running comparable material.
