Slitting & Rewinding Technical Guides

Practical, field-tested guides for slitting, rewinding and converting lines: how to size, select and maintain air shafts, differential shafts, magnetic powder brakes and clutches, tension controllers and web guiding systems. Written by XW Machinery application engineers for plant engineers and purchasing teams.

Not sure which shaft or brake fits your line? Send us your core size, roll weight and line speed — our engineers reply with a sizing recommendation.

如何選擇適合多複捲捲的正確差速軸

Pick the right differential shaft for multiple rewind rolls: count positions, choose the slip tech, set per-section torque, and fit diameter for uniform rolls.
