Durable Paper Tube Machine for Long‑term Use｜Model NRC350
1. Product Overview
1.1 Machine Introduction
NRC350 durable paper tube machine (spiral paper core machine) is a full‑set spiral winding production line dedicated to manufacturing spiral paper tubes from raw cardboard paper rolls. Also known as spiral paper core machine, this paper tube machine is a complete set of industrial equipment to convert cardboard paper rolls into finished spiral paper tube for daily and industrial usage.
The paper tube machine features simplified, compact and stable mechanical architecture for continuous heavy‑duty production.
Adopting simplified‑compact‑stable design philosophy, this spiral paper tube making machine supports single‑sided / double‑sided gluing, servo synchronous tracking cutting and automatic paper‑tape lubrication supply. It fits mass‑production needs for adhesive tape cores, DTY & POY textile paper cores and general‑purpose packing paper tubes.
1.2 Main Application Scenarios
- Transparent adhesive tape paper cores
- DTY & POY textile industry paper tubes
- General industrial packing paper tubes
- Multi‑layer spiral cardboard core tubes for various converting industries
