- Type: rotary roll-fed labeler
- Application: plastic pre-glued label from reel.
- Possible labelling combination on the same labeller.
- Suitable to handle cylindrical and shaped (rectangular, square, oval and so on) containers, even empty.
- Production speed from 60 to 1.000 bpm, depending on the model.
Technical features:
The two MACROPROBLEMS typical to this type of labeling machine has been eliminated in one go. Standard Roll-fed machines utilize:
HOT MELT Gluing the label edges by means of a glue roller is known to present some disadvantages:
- glue spray and relevant cleaning of the application cylinder;
- deposit of residual films or labels in the glue regulator (production stops due to cleaning operations);
- periodic cleaning of the pads during the working shifts;
- oily fumes produced by the glue heating (150°);
LABEL CUT until today, on all roll-fed machines, the label cut is performed by interaction of rotary cutting blades and one or two fixed ones. The difficulties in the adjustment of the blades during their replacement (4 to 6 hours) are well-known, as well as the production stops due to imperfect label cut.
 
 
ADHESLEEVE
Is the cheapest and most ecological solution in the field of Roll-fed labeling. It uses reels with already applied glue strips, which are applied to the label during the film converting process.
ADHESLEEVE is a type of labelling machine which uses pre-glued transparent or white roll-fed film with thicknesses lower than the films that are normally used on the classic Roll-Fed labellers.
Due to the use of thermal-shrinkable pre-glued roll-fed films, Roll-Adhesleeve, on the same machine, is able to handle shaped containers creating a Sleeve-type packaging at definitely lower costs (40% savings), granting the same packaging quality.
ADHESLEEVE allows the reduction of the label costs granting at the same time a higher efficiency of the labelling machine and of the line in its totality.
Eliminating the use of the hot melt is the first major innovation which hallmarks this machine offering the following advantages:
- environmental: absence of fumes produced by heating the hot melt (to around 150°C);
- sanitary: it is no longer necessary to utilize solvents to clean the label application cylinder (having eliminated the hot melt no residual glue is left to clean)
- ecological: the absence of hot melt makes the label free from any contamination, so 100% recyclable, together with the bottle and the cap.
The second important innovation introduced by this new labelling technology is the method of label cut. As this is no longer affected by fixed cutting blades interacting with rotary ones, several BIG PROBLEMS are easily solved:
- Adjustments: not necessary to adjust the cutting unit for various film thicknesses, considerable changes in the ambient temperature, no worn out blades etc.
- Replacements: it takes only 10 minutes (at most) to replace the cutting devices without tools or adjustments! The life of the new cutting devices is much longer than the classical cutting system;
- Efficiency: 100% elimination of production stops, potentially due to imperfect label cut, film stretching with consequent reduction of its thickness, different film thicknesses due to an excessive quantity of paint on a reel, etc. The new cutting devices do not require any servicing or adjustment. Films with a different thickness from standard ones can be used.

FAQ

FAQ: ADHESLEEVE
FUNCTIONING
1. Which are the storage times of pre-glued reels?
Storage times are provided by the converters, but we can assert that, without prejudice to the ambient conditions recommended for the standard label reels, the pre-glued reels have the same storage times. ( As per the technical sheets issued to the customers )
2. Will the label reels, which are pre-glued and on which the glue is applied in register, leave glue traces / filaments on the pull rollers causing machine stops?
Due to the experience gained with this type of machine, we can unconditionally rule out this problem.
3. Can the temperature range, that can be registered in a bottling plant, affect the cutting blades?
Absolutely not.
4. Can a label reel featuring any defect in thickness (even of a few micron) cause problems in the label cut with relevant machine jams?
This kind of problem won’t arise, if the range of thicknesses supplied by us is followed.
5. Is it necessary to adjust the cutting blades, as it is for a standard Roll-fed machine?
The new cutting system does not require any blade adjustment.
6. Standard Roll-fed machines require, after a variable amount of working hours, a machine stop to clean the transfer pads from any residual glue. Shall this cleaning operation be made on the new system as well?
No, the features of the new machine do not require for this operation.
7. Could any condensation on the bottles cause problems during the application of the labels?
The bottles should be almost dry, as per any standard Roll-fed machine.
8. Can the label be applied on both plastic and glass containers?
Of course, the label can be applied indifferently on PET, PE, HDPE and glass containers.
APPLIED LABEL
1. Is it possible that the label overlap on both cylindrical and square bottles presents waving edges?
The homogeneous spreading of the glue on the reel, both on the leading and on the closing edges, best grants the overlap’s hold, even in case of thermal-shrinking of the label on the container.
2. Should the containers/bottles be stored for a long time, would the glue crystallize thus making the labels detach?
The water based adhesive, which is used in this case, has an excellent resistance to aging and oxidation due to UV rays. From the data supplied by our customers with regards to containers stored for 24 months in various conditions, no glue abjection/oxidation, and the consequent label detachment, occurred.
3. By storing the containers normally in the fridge, will the condensation that usually develops in room temperature conditions cause the label detachment?
Several tests that have been carried out in the last months at all temperature ranges and they have removed the slightest doubt on this hypothetical problem.
4. Is the aspect of the label affected by the glue application during the converting process?
No, the aspect of the label will remain unchanged in the course of time.
