Winding direction for automatic label applicators

When labels go on an automatic applicator, winding direction isn't a preference, it's a machine spec. A wrongly wound roll can't be flipped by hand without rewinding the whole run. It's one of the few mistakes that genuinely stops a line, so it's worth a minute of attention at order time.

The eight standard options

The industry standard numbers positions 1 to 8. Options 1-4 mean labels face out of the roll, 5-8 face in. Within each group the orientation differs: head first, foot first, left edge first or right edge first.

• Position 1: face out, label head unwinds first.
• Position 3: face out, foot unwinds first.
• Positions 2 and 4: face out, left or right edge first - common on wrap-around labels.
• Positions 5-8: same orientations, but with the face wound inwards.

What else matters besides direction

• Core diameter: usually 40 mm or 76 mm. Your applicator typically accepts only one.
• Maximum roll outer diameter (OD): limited by machine space. Exceed it and the roll won't fit.
• Labels per roll: if you need a fixed count per roll for shift planning, say so.
• Gap between labels: some sensors need at least 3 mm to detect reliably.
• Sensor type: on clear materials an ultrasonic sensor is more reliable than an optical one.

What to send us in the brief

Ideal: applicator brand and model plus the winding position from the manual. If the manual isn't at hand, a photo of an old roll mounted on the machine settles it in two minutes. If labels are applied by hand, we wind standard: face out, head first.
