Armless: Compact Stacker for Finishing

Special compact-type stacker with split movable conveyor.

The stacker BERTECH model ARMLESS is the machine specifically developed to meet the needs of the finishing plant where in the same line both full hides and sides are processed.

This stacker is also useful for those tanneries that process small size leathers such as croupons, shoulders, sheep & goat skins on large machines (such as spray lines or ironing machines) and deposit the leathers on two stacks.
The name of the ARMLESS derives from the fact that this stacker is without arms since it is made of two movable, independent and self-standing conveyors that, when necessary, can work as a single one. A specific software allows the two conveyors to move either independently or perfectly paired and synchronized. Built following the highest quality standards, the stacker ARMLESS has a strong and solid structure made of materials that have been tested in tannery through long and intense productive cycles and its dimensions place it among the most compact machine of its category.
BERTECH is the sole manufacturer that equips its stackers ARMLESS and DYNAMIC of the anti-fall system of the lifting device considering it essential for the safety of the machine and operators.

Dynamic: Compact stacker for tanneries

Compact Traditional Stacker.

The BERTECH DYNAMIC stacker is built in two versions: one specific for the wet area and one for the dry area.

Built with high-quality materials, it has a solid and robust structure and is composed of components designed for use in tanneries. Its compact dimensions place it among the shortest in its category, while still featuring an inclined conveyor belt ramp ideal for any type of hide, without problems of rolling or slipping. BERTECH is the only manufacturer that equips its stackers, DYNAMIC and ARMLESS, as standard with the fall arrest system for the lifting group, an essential component for the total safety of the machine. Another feature that sets it apart is the usable working width, which is always equal to or greater than that described in the catalog.

Starlux: Rotary Press for Ironing and Printing

Through-feed press for ironing and embossing with automatic revolver-type roller changing device

Rotary press for continuous ironing, satin finishing and embossing. It has an automatic roller changing system with revolver device and an independent heating unit for each roller. It can store up to 3 large diameter operative rollers.

The Starlux can be supplied in a single version, double one or all three together.

The Starlux has the automatic roller changing system. Changing the rollers is very easy and fast. Each roller has its own thermal-oil heating unit for the independent management of the working temperatures. This system permits to change the operative roller many times a day without losses of time.

The operative rollers have an internal oil distribution system unique in its genre and the maximum difference of temperature all along the surface of the roller is one degree (1°C).

The Starlux can be supplied with one roller and the other two can be supplied separately thanks to the stability of the revolver roller changing system.

In conclusion the Starlux is the ideal machine to iron with pressure any kind of leather and soft leathers without compacting them, to process waxed leathers without changing their colours, to give an excellent glazing effect on the tops of the embossed leathers or to shine the tops of the milled leathers.

Think Green

Aware of its responsibilities, Bergi joined the “Supplier of Sustainable Technologies” project promoted by Assomac in 2017, with the aim of contributing to deepening the key issues related to the intelligent and conscious management of energy, water, and natural resources, with the perspective of qualifying the manufacturing industry’s production process as sustainable.

The focal point of the project is the “Green Label,” a voluntary declaration certifying the energy and environmental performance of machines, calculated based on internationally recognized parameters such as the CFP (Carbon Footprint, the amount of equivalent carbon dioxide emissions) measured using the shared and standardized Life Cycle Assessment (LCA) calculation methodology.

Special versions

MODEL S
Ideal machine for ironing by pressure or alternatively by thickness, for ironing only the peaks of heavy grains or ironing leathers without crushing the fibres, keeping them soft. The machine can work up to a pressure of 160 kg/cm. The motorized roller, which works the leather in synchro, allows thickness ironing and provides a very light touch on the leather surface without crushing it. It can be equipped with the transfer kit for the application of glossy, matte, laminated, sequined, patterned transfers to leather. The system is equipped with an accessory for protecting the felt with a reel of film.

MODEL V

Offers the possibility to change the contact angle between the leather and the operative roller by varying the geometry of the machine, thus allowing to increase and/or decrease the contact time of the leather with the heated roller.

MODEL SV

It represents a combination of the previous two.

PORTABLE HEATING UNIT

It's an accessory to be paired with the continuous press for printing with a winch, where at rest, there are rollers that need to be preheated before the change. This way, when the operator roller is changed, it's already at the desired temperature without any time loss. The heater is equipped with wheels and can be moved from one machine to another. It comes with an electrical system and is fully autonomous. It can reach temperatures of up to 160°C.

Rollers

S (600/800/1200)Buffing roller with wrapped paper and automatic paper tensioning system. This roller is supplied with an oscillator and rubber transport roller with physical characteristics and hardnesses chosen in cooperation with the customer to suit each type of processing.

PL (600/800/1200/1500/1800/2200/3000) V-shaped grooved green wool cloth polish roller. The inclined grooves guarantee a well spreading of the leather and an opening of the follicle for perfect cleaning. It is used in the intermediate stage to remove small defects and chemical impurities from the leather and is ideal for oiled and waxed leather. The green wool cloth roller can be manufactured in three different hardnesses (soft, medium, hard). The transport roller made of sandblasted and chrome-plated steel is supplied with this roller.

WW (600/800/1200/1500/1800/2200/3000)V-shaped grooved white wool cloth polish roller. The inclined grooves guarantee a well spreading of the leather and an opening of the follicle for perfect cleaning. The inclined grooves guarantee a well spreading of the leather and an opening of the follicle for perfect cleaning. It should be used in the final stage for polishing, as it has no warp and weft so it does not strip the skins. The transport roller made of sandblasted and chrome-plated steel is supplied with this roller.

C (600/800/1200/1500/1800) Channel-free cotton cloth roller made of cotton discs placed side by side. The discs are left soft for the application of the “carnauba” wax and the roller is equipped with a special support for the application and the dosage, through an external handle, of the wax. It is used in the final stage to obtain the “brush-off” effect on the finished leather. The transport roller made of sandblasted and chrome-plated steel is supplied with this roller.

Innova: Grinder for Soft Leather

Through-feed buffing machine for soft leathers

Through-feed roller buffing machine for 45° processing, suitable for soft leathers. The different inclination compared to the traditional Selecta, which works at 90°, makes it possible to halve the distance between the buffing point and the exit belt, ensuring the leather is laid out more flatly at the entrance of the dedusting machine.

Back to: Roller coating machines

Multicoat: Traditional Roller Infill Machine

Traditional roller infill machine.

The Multicoat roller padder is the latest version of BERGI S.p.A.’s traditional pigmenting machine.
Completely redesigned, the Multicoat is the result of many years of experience in the field of application, which began back in 1985.
In developing this new model, a lot of work has been done to achieve a machine that is simple to use yet highly versatile, to accompany the user in various work processes.
Wide opening of the doctor blade for easier roller cleaning, easily removable washing tank, electric adjustment of the thickness of the working right and left independently, are just some of the technical details that distinguish this machine.
