Rodolfo Comerio's 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.

Product category: Embossing equipment

Rodolfo Comerio's 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

Product category: Laminating plant

Rodolfo Comerio's 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

Company news




Aug 6, 2019

RODOLFO COMERIO conceives the first “super combined” calendering line

One of the major tire manufacturers in the world, for a new plant in India, chose RODOLFO COMERIO for the manufacturing of an innovative calendering line of 1,900 mm width, able to produce rubberized  textile cord and innerliner and that can also be prearranged for the future production of rubberized steel cord, thus maximizing profits and optimizing the return on invested capital.
This “super-combined” calendering line will be manufactured in RODOLFO COMERIO facilities in Solbiate Olona, together with the several Next-Generation calendering lines equipped with the most recent technologies invented and patented by the Italian manufacturer, ordered by global leader tire manufacturers.
Thanks to the Next-Generation calenders provided with the RC SF-FreeSystem Patented system of friction-free roll shifting, the tire manufacturers will be able to grant to their customers increasingly performing tires made of calendered material having the following characteristics and advantages:
- Improvement of the rubber penetration into the textile or steel cord
- Improvement of the thickness accuracy
- Improvement of the cords distribution end-count per inch (EPI or EPD)
- Possibility of reducing the thickness
- Improvement of the tires rolling performance
- Improvement of the tires resistance performance
- Improvement of the tires stability
- Consequent contribution to vehicle fuel saving
- Raw material saving
- Reduction of scraps
- Consequent cost saving
Moreover, the new technologies and the new systems adopted for the pre- and post-calender sections significantly increase productivity and guarantee high levels of safety for operators, whose manual interventions are considerably reduced thanks to highly automated production process solutions and consist of simply supervising the operations performed automatically by the new generation machines designed by RODOLFO COMERIO.
The “super-combined” calendering line marked RODOLFO COMERIO and destined for the Indian customer will be able to exceed the daily productivity of 370 tons and will be used to produce material for all types of tires, from giants for agriculture to tires for cars and also for those for 2 and 3-wheel vehicles.
RODOLFO COMERIO, thanks to an enormous use of resources, is bringing calendering technology - which in last few years had never known major developments - to levels that until recently were considered unattainable, with the aim of giving an innovative impulse to help its customers improve production yields but also of contributing to improve the performances of the finished product.
The company is also introducing new assistance plans to ensure even faster installations and start-up of plants to guarantee its customers a faster return on investment.
In RODOLFO COMERIO facilities, all the lines are always completely assembled, the tests and dry tests are performed for the solutions customized for the specific customer and, with the aid of 3D simulations, the installation and start-up phases in the customer’s building are simplified. For example, nowadays RODOLFO COMERIO is able to perform a mechanical installation of an entire line for the steel cord rubberizing within a period of time of approximately 2/3 weeks.
With the “RC TURN-KEYinstallation” pack, the Italian manufacturer supplies completely installed and commissioned calendering lines.
The experience gained over one hundred and fifty years of activity and an avant-garde Technical Department allow to offer customers this TURN-KEY pack, which is particularly suited to speed up the process and guarantee customers the maximum experience of the manufacturer.
The Customer thus has the advantage of having a single point of contact, limited responsibility to RODOLFO COMERIO, immediately knowing the final price of the whole plant and its installation and start-up, with no surprises and no need of overall cost containment.

RODOLFO COMERIO is the only interlocutor that deals with everything, more specifically:
• Perform technical inspection
• Study and identify the best solution for installation
• Prepare the necessary documentation
• Appoint the Works Management
• Appoint the Safety Coordinator
• Appoint a project manager
