SLR Machine

SLR super stretch sleeves

The SLRs apply stretch sleeve labels in a rotary architecture with a carousel equipped with different labeling stations (the number of stations depends on the speed to be reached), with both full body and partial sleeves. The machine’s architecture also allows the application of Super Stretch labels.

The bottles (or any other container) to be labeled are inserted, by means of a timing screw, into the starwheel synchronized with the rotating carousel of the machine.

The rotary carousel is equipped with a series of labeling stations, each essentially consisting of:

Divaricatore

  1. sleeve expanders
  2. sleeve gripper and pre-stretching
  3. sleeve positioning grippers
  4. bottle holding and lifting plate

The sleeves, pre-perforated and wound on a reel, are fed from an external sleeve feeder to the applying head which provides for the separation of the labels themselves along the perforation line and for their insertion on each of the sleeve expanders on the carousel. (Photo “Divaricatore”)

The expanders hold the label from the inside and rotate themsleves at 180 ° to insert the sleeve in the gripper and pre-stretch which keeps it in the open position to allow the insertion, from below upwards, of the bottle.

At this point the holding plate gradually raises the bottle pushing it into the label After the complete insertion of the bottle in the label, the plate makes the bottle descend to the conveyor level and leads it to the starwheel at the exit to transfer it back onto the conveyor belt.

  • Stretch sleeves are made of polyethylene, a completely recyclable material
  • Cost savings up to 50% compared to shrink systems and ROSO systems
  • Less use of materials up to 30% compared to the use of shrink materials (smaller layout, lower environmental impact in terms of carbon footprint
  • Suitable for super-stretch because the gripper is very robust and can open the sleeve with 6-8 sectors that distribute the stretch well
  • high speed rotary system
  • 360 ° visibility
  • Bright graphics and intense colors
  • Perfect adaptation to the shape of the container
  • Possibility to apply stretch labels also to containers with petaloid bottom
  • There is no need for glue or use of heat and therefore reduced use of energy
  • Full compatibility in terms of recycling, easy separation of the label from the container
  • Strong resistance to chemical agents
  • The machine can apply labels on containers both full and empty of PET, PE, PVC, metal and glass, dry or wet
  • Resistant to UV exposure
  • It is not necessary to provide for a preliminary drying of the bottles since the condensation on the walls favours the insertion of the stretch sleeve, instead of limiting it, as it happens with shrink sleeves.
  • No cutting systems or photocells are required to control the print register, to the advantage of system reliability.
  • Bottle sizes from 0.33 lt to 2 lt

Usually the stretch sleeves are supplied with a pre-perforation between one label and the other to facilitate the separation at the application on the bottle. Our machine can feature an alternative solution for the separation of the sleeve one from the other: the sleeve tubular, in its original flat form, without the pre-perforation, is fed through a pre-cutting unit, which is formed by a couple of parallel shafts with toothed blades.
Vision system for the detection and ejection of incorrectly labelled bottles.
