Cable Coil Stretch Film Wrapping Machine WM-4818

›

The WM-4818 is the packing station at the end of a coiling line — it wraps a finished cable coil in stretch film so it can be shipped as a clean, self-contained package. A C-shaped film ring passes through the coil bore and orbits the coil cross-section while support rollers index the coil around, laying a continuous spiral of film over the whole ring. It takes coils from 120 mm inner diameter up to 400 mm outer diameter and 50 to 120 mm high, at approximately 120 coils per hour, with wrap turns, speed and head/tail turns set on an English touch screen.

Specifications

Key features

• Open C-shaped film ring — it passes through the bore of the coil, so a closed ring coil can be loaded and unloaded without threading the film by hand
• Support rollers index the coil while the film carriage orbits, so the film overlaps in a continuous spiral around the whole ring instead of only over one segment
• English touch screen with separate fields for wrap turns, running speed, head-end turns, tail-end turns, completion delay and a piece counter
• Bearing-guided film carriage keeps film tension steady as the ring turns, and reloading a film roll is a single spindle change
• Runs on standard mini stretch film rolls with a 26 mm core, 65 mm outer diameter and 63 mm width — a common, cheap consumable anywhere in the world
• Plugs into a 220 V supply and draws 1.2 kW at most; no compressed air line is quoted in the manufacturer specification
• Free sample test — send us a sample coil, we wrap it on this machine and send you the video before you order

What it processes

• Packing finished ring coils of flexible cable, cord and hose for shipment or retail sale
• Wire and cable factories that sell coils by the piece and need each coil sealed against dust, moisture and unravelling
• Cut-to-length and distribution warehouses repacking drum stock into wrapped customer coils
• Coils of hose, tube, rope or welding wire that fall inside the 120–400 mm diameter and 50–120 mm height envelope

Suited for: wrapping already-wound ring coils in stretch film — coil bore 120 mm or larger, outer diameter up to 400 mm, coil height 50–120 mm. Not suited for: winding or tying the coil itself. To wind the coil, use the WM-4810 wire coiling machine with meter counter (inner hole 30–350 mm, 380 mm reel) or the WM-4813 meter counting coil winding and tying machine (coil inner diameter 50–280 mm, outer diameter 350 mm, bundle Ø 18–65 mm), both of which can be set to produce coils that sit inside this machine’s wrapping envelope. To only tie a coil rather than film it, the WM-4804 cable coil twist tie binding machine ties bundles of Ø 5–35 mm. For coils above 400 mm outer diameter, step up to the WM-4821 large cable coil stretch film wrapping machine (coil Ø 420–550 mm, height 110–125 mm). For a bore under 120 mm, or coils above 550 mm, ask us about a custom build.

Where it sits in the line

Every other machine in this category makes a coil or holds it together — this one turns the coil into a shippable package. A typical finished-goods line runs coil, tie, wrap: the WM-4810 or WM-4813 winds the measured coil, a tie holds the turns, and the WM-4818 films it. Until the coil is wrapped it is still a loose bundle — it picks up dust on the pallet, the outer turns slacken in transit, and the customer receives something that looks like scrap length instead of product. Stretch film compresses the turns, seals the coil against moisture and dirt, and gives the coil a face that a label sticks to.

How the wrap happens

The film carriage does not swing around the outside of the coil. It rides on an open C-shaped ring that passes straight through the bore, so the film goes around the coil’s cross-section the way tape goes around a doughnut. Because the ring is open at the top, the operator drops a closed coil onto the support rollers without cutting or threading anything. The rollers then index the coil forward between wrap cycles, so successive spirals of film overlap all the way around the circumference and come back to the starting point.

That is also why the head-end and tail-end turn counts are separate fields on the screen. Extra turns at the start anchor the film tail; extra turns at the end close the wrap so it does not peel back in the carton. Wrap count and running speed are set per product and stored as a program, so a factory running three coil sizes switches between them from the screen instead of re-teaching the machine.

Send us two or three of your actual coils. We wrap them on this machine, film the cycle, and send you both the video and the finished coils’ wrap quality before you commit to an order.
