Production line and factory setup overview
A small spiral-winding line converting slit kraft or recycled paper reels into industrial paper tubes and textile cores through paper conditioning, multi-reel pay-off, controlled ply gluing, spiral winding around a fixed mandrel, online length cutting, curing, optional recutting, edge finishing, dimensional and crush testing, bundling and dry storage. Product diameter, wall thickness and end use determine the mandrel, ply build and adhesive.
Recommended lowest-entry line configuration Launch one confirmed textile-yarn or film core, not a broad tube catalogue. Screen a two-head spiral winder covering roughly 20-200 mm internal diameter and 1-10 mm wall thickness, with 8-16 reel stands, stainless glue system, one contracted mandrel and belt, synchronized flying cutter, curing racks, precision recutter and crush/dimensional test tools. Buy pre-slit paper initially unless a slitter is justified by volume.
Production process and implementation sequence
- Paper-strip receiving and moisture conditioning
- Multi-reel loading and ply sequencing
- Adhesive preparation and controlled coating
- Spiral winding around the selected mandrel
- Synchronized online cutting
- Rack curing and moisture equalisation
- Precision recutting and edge finishing
- Dimension, straightness, crush and bundle release
Products, capacity and market fit
- Textile, tissue, film, tape and paper converters need dimensionally consistent winding cores.
- One buyer-approved diameter and crush strength keep mandrel and paper inventory low.
- Pre-slit paper permits a smaller entry before an industrial slitter is justified.
- Moisture, ply bond and straightness determine whether the core runs safely at speed.
- Textile-yarn winding core - Buyer spindle/chuck fit, internal diameter, wall, length, moisture, straightness and radial crush - Yarn, carpet and textile processors
- Film or paper converting core - Separate diameter, surface, crush and dynamic winding approval - Flexible packaging, tissue and adhesive-tape converters
