KRONES, represented by J.L. Lennard , has released an inline machine for sleeving. The Sleevematic DS Inline gives clients the option for upmarket bottle dress in the lower speed range.
In order to launch new products and establish them on the market, firms in the beverage industry frequently opt for quality-enhanced dress. The trends involved range from films and pressure-sensitive no-label-look dress to all categories of sleeving.
Krones has expanded its range of labellers to include the Sleevematic DS (Direct Sleeving) and the Sleevematic DS Inline. Clients can choose between the rotary models AF (Applicator Force) and DS (Direct Sleeving) as one and two-carousel variants, plus the DS as an inline model with either one or two cutting units, which handles shrink-sleeves.
With the inline variant, the sleeve is transferred directly. It is pulled over the entire container by a lowering device, and fixed in place on the conveyor. The sleeve is positioned flush with the container's base by the lowering device and the driven brushes.
An expanding mandrel opens the sleeve, to ensure more accurate cutting. A vacuum device for opening the sleeve is therefore not required, nor is an additional transfer station. In the cutting unit, the sleeve is cut accurately to the selected length by several servo-controlled blades, but not until it has already been fitted. After the sleeve has been transferred to the bottle, it is shrink-fitted in a steam tunnel.
Sleeving technology produces several advantages for the plant concerned. The machine doesn't have to be cleaned after every shift like other labellers. Since no glue is required, it doesn't need a glue heater. The shrink-sleeve can also serve simultaneously as a tamper-evident seal. What's more, the Sleevematic DS Inline offers exceptionally short changeover times to different containers or sleeves.
The machine is protected by hinged-door guards, and features a through conveyor with its own frequency-controlled drive. The Sleevematic DS Inline achieves speeds of up to 20,000 bottles an hour with one cutting unit, and twice that with two units.
