A common assumption is that a pop-up folder only runs one kind of paper. On the LKWP-980, the unwinding and tension sections are adjusted separately, so both wax paper and one-sided silicone paper run on the same machine. The two grades behave differently — wax paper is softer, silicone paper is slicker — so a grade change means retensioning the web, not modifying the machine. That is what lets one unit produce both baking liners and tray liners.
Folding governs how the sheets pull. The web is V-folded first, then cross-folded so adjacent sheets grip each other. Lift one sheet out of the box and the next one rises with it. If the fold angle is off, sheets either drag each other out in bunches or jam, which is why fold and cut-off settings matter more than raw speed.
Slitting sets finished width. The parent roll is up to 930mm wide and is cut into rows sized to the finished sheet. More rows mean more sheets per cycle. Tightly wound rolls or off-spec cores cause the unwind to wobble, which is what the tension control is there to hold steady.
Cut-off follows the end use. Serrated edges tear cleanly for hand-separated sheets; straight edges stay flat for automatic boxing. Both run on the same machine.
Finished sheets leave on a discharge conveyor that feeds straight into a boxing station. Everything is set from the touch screen — fold and slit parameters, plus running status on the same panel.

Q1: Can this machine run both wax paper and silicone paper?
Yes. Wax paper and one-sided silicone paper from 30–60 gsm both run on the LKWP-980. They differ in stiffness and surface slickness, so a grade change means adjusting the tension setting — not swapping parts or buying a second machine.
Q2: How do the wax paper and silicone paper products differ?
The finished form is the same pop-up folded sheet; the difference is the paper itself. Silicone paper handles grease and heat better, which suits tray liners. Wax paper suits dry baking and general lining. The customer picks the paper for the job, and the machine stays as it is.
Q3: Why do the sheets come out one after another?
Two folds working together. The V-fold sets each sheet's shape, then the cross fold overlaps neighbouring sheets. Pulling the top sheet lifts the corner of the one beneath — that overlap is what makes the pack a pop-up.
Q4: Is the fold angle adjustable?
Yes, fold and slit parameters are set on the touch screen. The angle and overlap need to suit the paper grammage: thinner paper has less stiffness, so it needs more overlap or the sheets pull out in clusters.
Q5: How wide can it cut, and how many rows per cycle?
The parent roll can be slit into as many rows as the finished width allows, within a maximum web of 930mm. More rows mean more sheets per cycle, so output scales with row count.
Q6: Serrated or straight edge — which fits my product?
Look at what happens downstream. Packs that consumers tear by hand for home baking suit serrated edges. Products that feed an automatic boxing line and need a clean, even edge suit straight cut. Both run on the same machine.
Q7: How long does a paper change take?
A change is a roll swap plus tension adjustment and a check on the fold settings — normal changeover work. The machine itself never needs rebuilding because of a paper change.
Q8: Can the finished sheets go straight into boxes?
Yes. Sheets leave on the discharge conveyor, and its end is the infeed position for a boxing station. The boxer is a separate unit, and the two interfaces can be matched at the selection stage.
Q9: What happens if the paper is outside the recommended range?
Below 30 gsm the paper lacks stiffness: folds collapse and sheets pull out in bunches. Above 60 gsm the paper is stiff, folding becomes difficult and roll diameter is limited. Choose paper within the stated range.
Q10: What does the workshop need to prepare?
A 380V three-phase supply with neutral and earth, and 0.5–0.8 MPa air at 300 L/min. The machine ships as a main unit plus a Roots fan, so confirm floor space and access route dimensions before ordering.
