Stop Turning Coils by Hand: Automatic Coil Turnover, Feeding and Wrapping Line

Executive summary Turning slit coils by hand or by crane is slow and puts people next to heavy, sharp-edged loads. Our line in this video turns the coil upright in a clamping upender, feeds it on a yellow roller conveyor and wraps it in an open-ring wrapper. The number of wrap passes follows from the coil size and the film overlap. We set both per project.

What the video shows

The video is a split-screen demo of one line. Flat slit coils lie on a long yellow roller conveyor, some with blue film on metal pallets at the side. At the turnover station, a blue frame with a yellow clamp holds a coil upright.

At the wrapping machine, an open-ring rotating arm wraps a coil standing upright. Other panels show the control console and the wrapping machine panel. FHOPE branding appears on the blue machines.

Turnover, feeding and wrapping in one line

Station What it does
Feeding The yellow roller conveyor carries flat slit coils in
Turnover The clamp upender stands the coil upright
Wrapping The open-ring arm wraps the upright coil through the eye
Outfeed The wrapped coil leaves for strapping or stacking

Turning the coil by machine keeps hands and crane hooks away from the coil edges. For eye-through wrapping on its own, see our eye-through film wrapping machine for steel and copper coils.

Wrap passes and film overlap per coil

Each pass of the ring lays one band of film through the eye. The passes needed depend on the mean circumference and the advance per pass. Illustrative example:

Item Value
Coil OD (illustrative) 1,200 mm
Coil ID (illustrative) 508 mm
OD circumference, π × 1,200 about 3,770 mm
Film width (illustrative) 100 mm
Advance per pass at 50% overlap 50 mm
Passes, 3,770 ÷ 50 about 75

We count passes at the OD, where overlap is lowest, so the whole coil gets at least 50%; the eye always gets more.

When this line fits

Situation Why the line helps
Slit coils arrive flat The upender stands them up for wrapping
Many coils per shift Turning and feeding no longer wait for a crane
Sharp coil edges Nobody handles the coil by hand
Coils need full cover The ring wraps through the eye

If coils must leave flat, we add a second turnover station after wrapping. For heavy coils that are stacked after wrapping, see our buyer’s guide to stretch wrapping and downender stacking.

Controls and safety

The clamp upender turns heavy coils and the ring arm rotates at speed. Keep people out of the turnover and wrapping zones while the line runs. Hands on a coil beside the upender are safe only with the station stopped and isolated.

The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 sets general requirements for packaging machines.

Selection checklist for a coil turnover and wrapping line

  • Slit coil OD, ID, width and weight range.
  • Coils per hour.
  • Eye position at infeed and at dispatch.
  • Film type and overlap.
  • Strapping or stacking after wrapping.
  • Floor space and conveyor length.

Engineering FAQ

Q: Why turn slit coils upright before wrapping? A: The open-ring wrapper in our line wraps the coil standing upright, through the eye.

Q: How many wrap passes does a coil take? A: About 75 for a 1,200 mm OD coil with 100 mm film at 50% overlap, counted at the OD, in our example.

Q: Where should overlap be set? A: At the OD, because the eye always gets more overlap.

Q: Can coils leave the line flat? A: Yes, with a second turnover station after wrapping.

Q: Does anyone handle the coil by hand? A: Not during the cycle. The conveyor feeds it, the upender turns it and the ring wraps it.

Next step

We plan your coil turnover and wrapping line in three steps:

  1. Submit your layout drawing with slit coil sizes and output to info@fhopepack.com.
  2. Receive a proposal within 48 hours, with the station layout and film plan.
  3. Book a site survey to check the floor space and conveyor run.
