Additional feeding desk for Junior 36

The additional feeding desk extends the area for manual sheet feeding in the Junior 36 machine and improves operator’s comfort.

Plexi magazine for feeding for Junior 36

The auxiliary plexiglass magazine for Junior 36 machine is a small laying away table installed directly to the machine feeder. This auxiliary unit is suitable for the customers who process jobs with repeating processing parameters (sheet size, paper weight, etc.) on the machine. White or other initiating sheets are stored in the magazine and used by the operator for job start and end so as to achieve 100% job processing without any wasted sheet.

Auxiliary piston compressor

We supply the auxiliary piston compressor to the customers who have insufficient supply of local compressed air available.

Belt drive for sensitive films

Chain drive is followed by slight speed fluctuations that can leave a visible graphic pattern on sensitive laminating films (rainbow, holographic and metallic). Belt drive is free of this problem. An option for the Sagitta 76 model only.

Film roll perforator

Additional perforator is positioned directly on the reel. It is used in case of thick foils for more reliable separation of sheets and also in specific cases when the standard method of film cutting before separation cannot be used.

On-roll film slitter

Additional film slitter is positioned directly on the reel. It is utilized if a film of the required width is not available. The on-roll film slitter is to be positioned in such position where it trims film directly in the reel to the required size. Use of the slitter unit may affect the speed of job processing (in the same way like e.g. paper weight); actual laminating is usually carried out at a lower speed.

Sheet preheating

The laminator can be equipped with IR sheet pre-heating system. The infra-red heater is positioned before the laminating roll, i.e. it heats printed sheets before their laminating. Sheet heating before lamination brings good results in particular when laminating digitally printed sheets when toner is activated again by heat and the result of lamination is considerably higher.

For technical reasons, the tilting guiding plates which otherwise are standard parts of the machine must be removed from the machine if pre-heating system is mounted.

Polyurethane coated pressure roll

The pressure roll with polyurethane surface has higher surface hardness (90 shore) and longer service life. It is suitable in particular for processing of a higher number of jobs with sheets of a higher paper weight – the roll is more resistant to wear. Actual color may vary from shown picture.

Teflon coated pressure roll

Bottom pressure roll made of a non-adhering material is suitable for processing digitally printed materials. Thanks to its surface properties, it avoids unpleasant situations with sheet sticking on the roll and contributes to easier machine maintenance. The teflon pressure roll is installed at final machine assembly instead of a rubber pressure roll as a standard.

We recommend it for laminators intended for laminating digitally printed sheets, i.e. for Junior and Amiga series. Actual color may vary from shown image.

Universal pallet positioning kit

This option is to make the pallet driving in the feeder easier for an operator. Laser marker is drawing a line to be followed by operator in order to spot pallet into a right position. Side piling guide on operator side was re-designed to simplify the pile precise positioning. An option for the Sagitta 76 model only.

Air Shaft

The air shaft is intended for replacement of a stanard film unwinding shaft and makes replacement of film rolls very fast and easy.

Embossing modification

Structured lamination (embossing) system in a form of separately supplied embossing rolls is available for the Amiga 52 Tandem Embossing machine. The required design of the laminated sheets is achieved by replacement of the smooth laminating roll by the embossing roll. Embossing takes place together with laminating in this way.

PSA separation bar as addition to OTF (Pressure Sensitive Adhesive film))

The standard laminator is fitted with a rewinding unit and an additional bar for PSA film (pressure sensitive adhesive film) lamination. Interleaving paper is removed through the auxiliary bar and wound up on a rewinding shaft before entry in the laminating unit. The machine has to be fitted with a flying or hot knife for separation of such materials.

Vibrating knives

The vibration cutting knives represent an option for the system for sheet separation on the Delta 52 machine. Delta 52 machine is equipped only with the built-in perforator in the basic configuration; the vibration knives represent an auxiliary unit of the system for more reliable film slitting between sheets suitable in particular for high speed laminating.

Hot knife

The hot knife is used for separation of sheets in the cases when the standard process cannot be used. The hot knife is heated electrically and sheet separation takes place only after knife pressing by rotational movement of the unit against laminating film. The hot knife assembly includes an ultrasound detector which monitors sheet overlap and if overlap is indicated, a signal to the knife for separation is sent.

Automatic skew wheel

The skew wheel (roller) is a unit installed in the end of the machine behind the snapping rolls which create a wave on the sheet being laminated through roller turning and roller thrust force. Wave creating on the sheet makes separation easier for the snapping rolls.

The action of the automatic skew wheel (roller swinging mounting) when compared with the standard roller fixed mounting used on all laminators consists in the fact that a bar with roller is fitted with a pneumatic cylinder which presses the roller against sheet as required. Use of this option is suitable especially for long sheets where permanent roller pressing could result in formation of folds on the sheet. In case of the automatic skew wheel, the operator defines for how long a wave should be created and from what moment, i.e. when the roller should be pressed against sheet. The roller is pressed before fall of the snapping roll and is lifted immediately after sheet separation. Thanks to the roller swinging mounting, the operator can select from 3 modes:
– the roller pressed permanently (it operates like a fixed roller),
– the roller open permanently (not in use),
– the operator selects a cycle according to the sheet length

External OTF Module (OTF = Over Toner Foiling)

“Toner Foiling” is a solution for application of film which creates special effects (glossy, colourful or metallic areas) on the digitally printed sheet. The standard laminator is provided also with a winding up unit, a separation bar and a support sheet metal. The substrate film with surface sensitive with respect to toner passes through the machine in the same way as at standard lamination. The surface layer of the film adheres to the sheet areas printed with toner while white (i.e. unprinted) areas remain without effect in case of contact of the film with the processed substrate. The transfer film is wound up on a shaft at process completing.

Antistatic bar

The antistatic bar is a device which discharges static electricity created at friction between the laminated sheet and machine parts. This measure prevents in problems with sheet winding up on snapping roll and in potential damage of the machine. The bar is installed on the separator directly above snapping roll.

Air Ionizer

Jogger

The jogging table is type of the unloading table which is fitted with a vibration motor and ensures better sheet stacking on the table in this way. The jogger is produced in sizes for both B2 and B1 sheets and is available for various machine models either in basic configuration or as an option instead of the fixed delivery desk.

Automatic stacker (stacking onto pallet)

We offer the automatic sheet stacker in B1 and B2 size. It is a separate unit which is to be positioned behind the laminator instead of the delivery desk. The machines are ready for the sheet unloading in stacker variant so that they are fitted with a sheet separation detector; i.e. if sheet is not separated, the machine is slowed down and consequently stopped in order to avoid in sheet damage.

Film roll lift

The film roll lift is a simple lifting mechanism for easy film reel replacement in the machine. Replacement of even large film reels can be handled only by one person without problems.
