✂️ Slitting Looks Like “Just Cutting Width”. Most Customer Complaints About Telescoping, Edge Quality and Wrong OD Start Here.
📖 9-min read · Slitting · Production + PPC + Quality
After printing and lamination, wide rolls must become the exact widths the pouching line or customer needs. Slitting is fast — often 300–600 m/min — and that speed hides how sensitive tension, blade condition and wind-up settings are. This article focuses on what actually fails on the floor.
- Speed: often 300–600 m/min
- Main defects from poor slitting: telescoping, soft/hard edges, dust, width variation, wrong OD
- Key controls: tension profile, blade sharpness/type, lay-on pressure, core quality
1. What the Slitter Actually Does
Unwind the wide roll → control tension → cut with razor or shear knives into set widths → rewind each strip onto cores at controlled tension and taper. Every one of those steps can create a complaint that appears only at the customer or on the pouching machine.
2. Control Points PPC Should Track
- Correct width program vs order (wrong width is pure waste)
- Blade change discipline (dull blades create dust and poor edges)
- Tension recipe by structure (thin films need different settings than heavy laminates)
- Finished OD and meter length match to what pouching or customer expects

✂️ स्लिटिंग “सिर्फ चौड़ाई काटना” लगता है। टेलीस्कोपिंग, एज क्वालिटी और गलत OD की ज्यादातर शिकायतें यहीं से शुरू होती हैं।

चौड़े रोल को सही चौड़ाई में काटना तेज काम है (अक्सर 300–600 m/min)। स्पीड छुपा देती है कि टेंशन, ब्लेड और वाइंड-अप कितने संवेदनशील हैं।
