Designed as an inline alternative to manual film taping and high-energy thermal shrink tunnels, this cold-wrapping system utilizes a dynamic orbital ring to apply pre-tensioned stretch film across top faces, bottom undersides, and longitudinal edges (typically 20\u201335 \u00b5m LLDPE film at 150%\u2013250% motorized pre-stretch).

Engineering Frequently Asked Questions<\/h2>\n<p><strong>Q: Can cold stretch wrapping damage delicate painted or high-gloss surfaces?<\/strong>\nA: No. Conveyor rollers are sleeved in non-marking Shore A 75 polyurethane or NBR rubber, completely eliminating metal-to-metal rubbing. Furthermore, the powered pre-stretch carriage elongates the film before it leaves the dispenser, meaning the film touches the panel with uniform elastic recovery rather than abrasive sliding friction.<\/p>\n<p><strong>Q: How does the system handle wide, thin panels without lifting them off the rollers?<\/strong>\nA: Thin panels with broad surface areas are susceptible to aerodynamic flutter and tangential film pulling. The machine utilizes synchronized overhead pneumatic press rollers lined with non-marking soft rubber. Regulated under low pressure (0.15\u20130.25 MPa), these rollers exert stabilizing downforce along the workpiece centerline, keeping the board seated firmly on the drive rollers.<\/p>\n<p><strong>Q: Does the system require a human operator during wrapping?<\/strong>\nA: No. Infeed optical sensors register panel presence, overhead clamps engage dynamically, the film carriage anchors and wraps the part, and the pneumatic cutter and brush finish the tail automatically. Personnel are required only for loading raw film rolls and routine maintenance.<\/p>\n<p><strong>Q: What is the maximum throughput achievable on standard interior doors?<\/strong>\nA: For a standard 2,000 mm door running at a conveyor speed of 6.0 m\/min with 50% overlap, active wrapping requires approximately 20 seconds. Factoring in infeed positioning and tail cutting, total floor-to-floor cycle time runs between 28 and 35 seconds per door (yielding 90 to 110 doors per hour).<\/p>\n<hr \/>\n<h2>10.
