The selection of roll label feeders revolves around the reel; sheet label feeders have no reel. The incoming material is pre-cut individual sheets, attached to lower paper, stacked in the magazine; peeling relies on the traction mechanism tensioning the lower paper to separate the sheets from the peeling platform. Therefore, the exclusive dimensions of the sheet model are only three: lower paper length, peeling width, and magazine depth.
Boundaries of the Three Models
| Model | Lower Paper Length (mm) | Peeling Width (mm) | Magazine Depth (mm) | Body (L×W×H mm) | Net Weight |
|---|---|---|---|---|---|
| PLF-100 | 50~230 | ≤105 | 150 | 970×260×260 | 40 kg |
| PLF-200 | 50~300 | ≤200 | 150 | 970×320×260 | 50 kg |
| PLF-300 | 50~350 | ≤300 | 150 | 970×483×260 | 60 kg |
The number after the model hyphen is the upper limit of peeling width, and the upper limit of lower paper length scales up accordingly: from 230 to 300, then to 350 mm. The magazine depth of all three models is 150 mm—what changes with lower paper length is the traction stroke, not the magazine capacity.
Why the Lower Limit of Lower Paper Length Is 50 mm
50 mm is the shared lower limit of all three models. If the lower paper is shorter than this, when the traction mechanism clamps the front end of the lower paper and pulls it back, the length available for tensioning is insufficient, and the separation of the sheet on the peeling platform becomes unstable. Conversely, a lower paper length exceeding 350 mm is also not within the standard models: either customize the traction stroke according to the lower paper, or switch to a non-standard peeling station.
How to Read the 150 mm Magazine Depth
The magazine depth is the layer that holds the sheets, and it has no conversion relationship with the lower paper length. How many sheets a magazine can hold depends on the stacked height of the sheets, so two things must be confirmed with the material supplier: the thickness of a single sheet (including lower paper), and the allowable stacking height of the magazine. This article does not provide calculated values.
Feeding Cycle and Operation Mode
The feeding cycle of the sheet model is 2~3 s, which is not on the same order of magnitude as the 0.1~2 s of the roll model—this is determined by the incoming material form, as the peeling action changes from continuous traction to sheet-by-sheet separation. The sheet model has two additional capabilities that the roll model does not: the operation mode can be selected as inline or standalone, and the drive method is electric plus pneumatic. The remaining positioning specifications are consistent with the roll model: placement accuracy ±0.2 mm, angle accuracy ±0.5°, position fine-tuned via fiber optics plus touchscreen, DC 24 V power supply (average current 80 mA, peak 1 A, power supply capacity should be configured for greater than 2 A).
What Materials Must Use Sheet Feeding
The premise is materials that must not be bent. Industry patent materials published in 2026, when describing sheet label feeders, give the incoming material premise as: certain materials cannot be bent and wound into rolls, and can only be cut into individual sheets for packaging and transport. On the production line, this is usually thicker metal reinforcement sheets, larger-sized sheet materials, or materials whose surfaces cannot withstand winding stress. For how to choose between sheet and roll, there is a separate article on the site.
Five Items to Ask for Selection
Peeling width (must accommodate the wider sheet), lower paper length, thickness of a single sheet including lower paper, incoming material form (whether already cut into sheets), and whether the feeder is installed beside the placement machine or at a standalone peeling station. When all five are complete, the reply gives a specific model, not a candidate list. The full series is on the sheet label feeder page, and an example of a wide-format model is PLF-200.
