Product category: Laminating plant

Laminating machines

This type of equipment is suggested for products that require high stability and quality and for a maximum variety of treated items.

It is designed for hot lamination of up to six sheets or combined lamination using adhesives in one single work process and for subsequent embossing.

The heart of this type of equipment is the gradual and independent heating of each sheet on small diameter rolls, placed in very closed proximity, with specific surface finish and internal construction, appropriately driven, heated and cooled in order to provide the sheet with the best laminating conditions.

The sheets are laminated one by one with very wide entry angles to avoid air inclusions with the heating process being completed on other, small diameter rolls.

The material is embossed in a vertical position, after a final heating process with an infrared unit for adjustable and graduated heating across its width and length, with the engraved and rubber rolls designed to obtain the best thermal exchange between fluid and sheet, the absolute temperature accuracy and minimum possible flexions across the entire width.

Efficient control units for adjusting tension and the temperature, in addition to the subsequent sheet take-off, stabilizing and cooling rolls guarantee the production of a perfectly laminated material without any tension or with no air inclusions, with increased engraving speed and accuracy, perfectly flat and with no elastic memory

The remarkable production rates and the high efficiency of these equipment make the production of a wide range of products possible:

• Thickness range of the materials to be laminated - 0,06 - 1,2 mm

• Thickness range of finished products - 0,5 - 2,5 mm

• Film width more than - 2.500 mm

• Line speed higher than 50 m/min

Embossing units

RODOLFO COMERIO proposes its exclusive and patented system able to perform the embossing in register of any kind of material (extensible or reinforced).

This aim is achieved thanks to an highly innovative laminating and embossing line that allows to:

-Continuously unwind and automatically cut and join different materials to be laminated

-Center them

-Preheat them by means of infrared heaters

-Continuously laminate them

-Emboss the back surface of the obtained laminated material

-Emboss in register, by keeping in synchrony the pattern of the printed film with the engraving of the embossing roll

-The embossing unit is furthermore provided with a revolving device allowing the quick change of the engraved roll, minimizing production interruption and consequently the scraps

-Cool the laminated and embossed material

-Trim, cut and stack the slabs

Rotogravure Printing Machines

RODOLFO COMERIO offers rotogravure printing machines suitable for soft extensible films, which are typically troublesome for register keeping and request frequent production changes.

Their distinguishing features are their very accurate sheet conveying, their control in electrical axis of the printing units, the very short path between the printing units, the efficient horizontal drying tunnels and an innovative system for quick roll change.

RODOLFO COMERIO offers combined lines both for varnish, primer and colour printing and for water-based or solvent-based lacquering of extruded or calendered PVC film, artificial leather and coated fabrics, as well as for laminating with reinforcing fabrics or soft films and for surface embossing, for very different productions.

Distinguishing features of these lines are high-performing vertical drying tunnels provided with independent ventilation for each printing unit.

Roll mills

Machines designed to be installed in the calendering lines for plastics and rubber production or to be used in series in mixing rooms or separately, they all involve the fundamental principles of sturdiness, manoeuvrability and economy.

These principles are exalted by the use of steel frames and rolls, provided with self-aligning bearings, driven through reduction gears and independent universal joints or through hydraulic motors, and equipped with attachments purposely designed to eliminate any manual procedure.

These roll mills are suitable to:

- Act as a lung in calendering lines for plastics

- Automatically prepare the rubber compound in the mixing rooms

- Act as crackers and feeders of rubber calendering lines

- Mix special products such as silicone, asbestos, medical products, plastics and rubber in general

Product category: Rolls


The calender rolls are the heart of the machine, and the condition of the rolls affects the quality of the calendered product. The planarity of the film, the machine direction and transverse profiles, the surface aspect of the film, as well as the calendering rheology, basically depend upon the surface precision and finish of the rolls.

The rolls realized by RODOLFO COMERIO are ground, guaranteeing a very high working precision, by recreating the same working conditions under which they shall work, using the same bearings as used in the calender and applying the identical preloading forces.

- Surface linearity < 2 m

- Surface concentricity < 3 m

Inspecting Rereeling Machines

Machines suitably designed to allow the packaging of the rolls guaranteeing high output speeds maintaining full quality control with significant savings in term of labour costs.

These machines are perfectly suitable for quality control, cutting, automatic winding and packaging of PVC reels or other materials, single or laminated with other sheets, or with fabrics of different nature or paper.

Final packaging of the reels can be performed in different ways:

- with plastic film or paper sheet, automatically unwound and cut

- with shrinkable film which wraps up the roll at the outlet of rereeling machine

- by sealing the material end-tail by means of sprayed adhesive before rolling up the last material centimetres.

Phases of material threading up, winding with established length, sheet cutting, loading of the new cardboard core, packaging and storage follow a completely automatic cycle, with high output speed and total guarantee of constant tension and non-deformability of the sheet.

Winding is performed either by means of contact winding through a contact roll or by spindle axis control or using both systems.

Technical data:

Diameter of the reel to be unwound – 1500 mm

Maximum reel diameter wound in contact – 500 mm

Maximum reel diameter wound axially – 1000 mm

Diameter and width of winding cores - variables

Number of wound reels on core - variable

Cutting sequence time - < 1 min
