Fully Automatic PP Strap Winder with Inward-Winding Conveyor-Type and Outer-Layer Film Wrapping
Production Description
This fully automatic PP strap winder achieves a complete automatic cycle including winding, strap cutting, head clamping, outer-layer film wrapping, 90° coil flipping, and conveying to the discharge belt. A servo motor drives the traverse, with strap width (5-19 mm) set on the touchscreen.
After winding completes, the machine automatically stops, changes the paper tube, cuts the strap, clamps the tail, wraps the outer layer with film, flips the finished coil 90° onto the conveyor belt, returns to origin, and starts the next cycle - all without manual intervention.
The winding shaft is driven by a servo gear motor, with speed regulated by the tension arm angle and tension adjustable via a spring screw, effectively reducing coil curvature deformation. Measurement modes include length (meter) and weight.

Frequently Asked Questions
Is the paper tube change automatic?
Yes. After winding completes, the machine automatically stops, changes to a new paper tube, and performs strap cutting and head clamping.
Does outer film wrapping happen immediately after winding?
Yes. After winding, the machine cuts the strap, clamps the tail, automatically wraps the outer protective film, and only then flips the coil for discharge.
How is the finished coil removed from the machine?
The machine automatically flips the coil 90° onto the conveyor belt, which then carries it out. The operator simply picks it up at the end of the conveyor.
How is tension adjusted, and why does it reduce bending?
Tension is adjusted via a spring screw, while the tension arm angle controls winding speed. Proper tension prevents over-stretching or looseness, thus reducing curvature deformation after winding.
Is it easy to change strap width?
Yes. Simply select the corresponding width (5-19 mm) on the touchscreen, and the servo traverse system adapts automatically - no mechanical part replacement needed.
