One person used to stand at a bin, dropping wads into caps by hand. The 140 L does it instead. A star wheel indexes every cap into position, and a vacuum cup seats the wad, 40 to 60 times a minute, placed the same way every time.
Built for 20 mm to 120 mm caps on one frame, running induction foil liners, EP or Foam liners, or pulp wads without a head change.

Most plants that outgrow hand-lining caps don’t need the fastest machine in the catalog. They need one that gets the wad in straight, every time, without adding a second operator to the line. That’s what the 140 L is built for: a single-head machine that holds 40 to 60 caps a minute for a full shift, not just the first ten minutes.
It sits at the entry point of Sigma CapSeal’s wad/liner inserting range. If your SKU count or line speed outgrows a single head, the 240 L and 440 L run the same indexing and vacuum principle with more heads bolted on.
Four things happen between a bin of loose caps and a finished, lined cap dropping off the machine. Here’s the sequence, in the order it happens on the frame.
1
Caps load into the bowl feeder loose, in any orientation. The bowl sorts and flips them until every cap sits cavity-facing-up, then feeds them onto the conveyor belt one after another.
2
The belt carries oriented caps to the star wheel, which is the part actually doing the timing work. Each pocket on the wheel picks up one cap and holds it in place.
3
Separately, pre-cut wads sit stacked in a gravity magazine, liner-face-down, so the foil or EP surface is presented in exactly the orientation the vacuum head expects.
4
Every time the star wheel indexes forward, a vacuum cup lifts the bottom wad off the magazine stack and seats it into the cap held below. One index, one cap, one wad, 40 to 60 times a minute.

What matters when this machine has to run a shift without babysitting.
Mechanical timing means the cap is always in the same position when the vacuum cup fires. That consistency is what keeps reject rates down at the capping and sealing stage downstream.
Small pharma caps and large edible-oil caps run on the same base machine. Changing size means swapping star wheel and bowl tooling, not buying a second unit.
A vacuum cup actively places the wad rather than letting it fall, so it seats flat and centered even on caps that aren’t perfectly level on the star wheel.
Induction foil liners, EP or Foam liners, and pulp wads all run through the same vacuum head. What matters is the wad’s outer diameter matching the cap, not what’s laminated to it.
Run it as a standalone station feeding lined caps into totes, or position it ahead of a capping machine and an induction sealer so caps arrive pre-lined with no manual step in between.
Everything touching the cap or wad is stainless steel on a self-standing frame, built to the same GMP baseline as the rest of the Sigma range.
The star wheel and vacuum head stay fixed. What changes underneath them is the cap, the wad, and the container it ends up on.
All three run the same star-wheel indexing and vacuum transfer principle. The only real decision is how many caps a minute your line needs.
240 L
Double head, 80-120 CPM
Mid-volume lines running one or two cap sizes
440 L
Four head, 160-200 CPM
High-volume bottling lines feeding a fast capper
Running small pharma caps at high volume? Step up to the 240 L or 440 L. Running 80-120 mm caps at moderate, single-shift volume? The 140 L is sized for exactly that; don’t pay for heads you won’t use.
A single operator hand-lining caps rarely holds this pace for a full shift without drift in placement quality. The 140 L holds it at minute sixty the same as minute one.
A wad seated off-center or upside-down shows up later as a failed induction seal, and by then it’s a rejected bottle, not just a rejected cap. Catching it at the wad/liner-insertion stage instead is the whole point of automating this step.
A plant running two SKUs at, say, 30 mm and 90 mm doesn’t need two machines side by side. It needs one 140 L and two sets of star wheel and bowl feeder tooling.
Plenty of buyers run it by itself, feeding lined caps into totes for a separate capping step. Just as many bolt it straight onto the line, right before the capper and sealer, so caps show up already lined.
Nothing about the wad/liner insertion cycle changes. It’s the same bowl feeder, star wheel and vacuum sequence in both setups. Only the destination changes: straight to your capping head instead of into a bin.

Per Cap Size
A consistently lined cap, wherever a hand-inserted wad would slow the line down or introduce a bad seal downstream.
A centered wad ahead of induction sealing, so tamper evidence holds up at inspection.
Matches the speed a bottling line needs between filler and capper, without a second operator at the wadding station.
Airtight liner seating for cold-chain product, where a bad seal means a recalled batch.
Handles the larger end of the cap range for jugs and bottles without a second machine.
Liner seating that holds up on drums and jerricans that get handled hard in transit.
Handles the smaller end of the cap range at retail-line speed, where a crooked liner is obvious on the shelf.
Liner compatibility across foil and EP wads for containers with specific barrier needs.
Quick tooling changeover between customer SKUs without swapping machines.
High-volume liner insertion built into fast-moving consumer goods packaging lines.
The 140 L needs less planning than it might look like on paper. One electrical spec to confirm, a self-standing frame, and changeover parts sized once you send your cap and wad dimensions.

One-Stop Solution: Insertion to Inspection
Pair the 140 L with Sigma CapSeal’s cap assembly, induction sealing and vision inspection equipment, so wad/liner insertion, cap assembly, induction sealing and vision inspection all come from one applications team, one service network, and one set of spare parts to stock.
Why Choose Sigma CapSeal for Wad/Liner Insertion
Sigma CapSeal has built cap and closure automation since 1974 and shipped India and Asia’s first induction sealer in 1989. That same engineering team designed the star-wheel and vacuum system behind the 140 L, 240 L and 440 L. It’s equipment running in more than 85 countries, backed by a DSIR-certified R and D lab and a 98.94 percent on-time delivery record.

What packaging engineers, plant managers and procurement teams ask before they buy.
A bowl feeder orients caps and feeds them to a star wheel. On every index, a vacuum cup lifts a wad from the magazine and drops it into the cap below.
Head count and speed. 140 L: single head, 40-60 CPM. 240 L: double head, 80-120 CPM. 440 L: four heads, 160-200 CPM.
Either. Run it standalone into bins, or in-line ahead of a capper and induction sealer.
Yes, 415 V AC, three phase, 50/60 Hz, same as the rest of the Sigma range.
20 mm to 120 mm, on the same frame. Changing size means swapping star wheel and bowl feeder tooling, not buying a different machine.
Induction foil liners, EP or Foam liners, and pulp board wads, all on the same vacuum head. What matters is the wad’s diameter, not the liner material.
Depends on your cap and wad size, so we confirm it against your SKU at quoting rather than quoting one number for the whole range.
