Compact Decoiler and Straightener YSL-400–1000 | Yiming, Dongguan, China

Yiming's Compact Decoiler and Straightener (YSL series) combines an uncoiler and a leveller in one machine. It unwinds coil and flattens it for plate and coil material from 1.0–6.0 mm thick.

It is offered in five models for coil widths of 400, 500, 600, 800 and 1,000 mm. Leveling speed is 0–15 m/min, set by a frequency converter, and the leveling rollers are driven by large-module gears so the material surface is not rubbed or scratched.

Key Features

• Pneumatic compression relaxation creates enough tension to feed material into the straightening rollers, turning in step with them
• Head flattening device at the front of the feed roller helps the coil end enter the straightening wheels smoothly
• High-power straightening motor with worm gear reducer and sprocket chain drive gives a large leveling force
• Upper and lower rollers are driven together by large-module gears
• Worm gear fine-tuning for leveling adjustment
• Manual expansion of the material rack, supplied with 4 A-shaped racks, plus a coil pressing arm and powered inching of the rack
• Button interface operation and feeding and discharging guide device as standard
