240 M: Precut Wad/Liner Inserting Machine with Vacuum Pick-and-Place System
A bowl feeder, star wheel and vacuum pick-and-place system automatically insert precut induction/EP/Foam wads into 20-50 mm caps.
Caps are fed into the bowl feeder and oriented cavity-facing-up, then delivered by a conveying belt to a star wheel that holds each cap in position. Each time the star wheel indexes, the vacuum system picks a precut induction/EP/Foam wad from the magazine and places it into the cap. An automatic count function stops the machine once your set quantity is reached.

A Precut Wad/Liner Inserting Machine with Vacuum Pick-and-Place System
The 240 M automatically inserts precut induction/EP/Foam wads into caps. Caps are fed into a bowl feeder and oriented cavity-facing-up, then delivered by a conveying belt to a star wheel that holds each cap in position while the vacuum system places a wad from the magazine into it.
It is built for 20-50 mm caps. All changeparts, including the star wheel, wad holder assembly and magazine, are machined on CNC equipment and are specific to the cap and wad size in use.
How the 240 M Works
Caps are fed in a bowl feeder, oriented cavity-facing-up, and delivered by a conveying belt to a star wheel that holds each cap in position. Each time the star wheel indexes, the vacuum system picks a wad from the magazine and places it into the cap.
1
Orient and Feed
A bowl feeder orients caps cavity-facing-up and delivers them by conveying belt toward the indexing station.
2
Wad Magazine
Precut induction/EP/Foam wads sit stacked aluminum-facing-down in a magazine, staged for pickup one at a time.
3
Star Wheel Indexing
The star wheel holds each cap in a fixed position as it advances to the placement station.
4
Vacuum Pick and Place
Each time the star wheel indexes, a vacuum cup picks one wad from the magazine and places it into the cap.
Machine Features
Built for repeatable wad/liner placement on 20-50 mm caps.
Star Wheel Cap Holding
The star wheel holds each cap in a fixed position as it indexes through the wad placement station.
Vacuum Pick-and-Place
Each time the star wheel indexes, the vacuum system picks a precut induction/EP/Foam wad from the magazine and places it into the cap.
Automatic Count Function
The machine can stop automatically once it reaches a set number of caps, which improves the efficiency of subsequent work.
Safety Stop for Missing Cap or Wad
Safety protection devices stop the machine automatically when there is no cap or no liner present.
CNC-Machined Changeparts
All parts are machined on CNC equipment for accuracy. Changeparts are designed specific to a cap and wad size dimension.
Stainless Steel Cap-Contact Parts
The bowl feeder, magazine and other cap-contact parts are stainless steel; the machine body is M S powder coated.

Automatic Count Function
The machine stops automatically once it reaches your set number of caps, improving the efficiency of subsequent work.
3 Changeparts
Switching Cap or Wad Size
Changing cap or wad size means changing the star wheels, wad holder assembly and magazine. It’s a changeover, not a different machine.
Safety Stop
No Cap or No Liner Present
Safety protection devices stop the machine automatically when there is no cap or no liner present.

Frequently Asked Questions: 240 M
How does the 240 M insert wads/liners into caps?
Caps are fed into a bowl feeder and oriented cavity-facing-up, then delivered by a conveying belt to a star wheel that holds each cap in position. Precut induction/EP/Foam wads are stacked aluminum-facing-down in a magazine. Each time the star wheel indexes, the vacuum system picks a wad from the magazine and places it into the cap.
What wad type does it insert?
Precut induction/EP/Foam wads.
What happens if a cap or wad is missing?
The machine is equipped with safety protection devices that stop it automatically when there is no cap or no liner present.
How does the vacuum pick-and-place system work?
The star wheel indexes caps under a vacuum pick-and-place system that inserts one precut liner into each cap as it passes.
What cap sizes does the 240 M handle?
20-50 mm caps.
What does the automatic count function do?
The machine can stop automatically once it reaches a set number of caps, which improves the efficiency of subsequent work.
What changes when I switch cap or wad size?
All changeparts are designed specific to a cap and wad size dimension. Changing cap or wad size means changing the star wheels at the wading station, the wad holder assembly and the magazine.
