UNWINDING UNIT

This is where the coil paper is unwound and delivered to the machine to begin processing. Depending on the diameter of the coil axis, different coil heads can be attached to the coil and inserted in the unwinding unit. The coil width differs by the machine specifications.

A coil with a minimum diameter of 1550 mm and a maximum diameter of 2500 mm can be attached to the unwinding unit.

It can be either a single or double in the machine, depending on the customer’s requirements. It is capable of working with single, double, or triple layers of semi-finished goods. The shaft system requires the operator to remove and reinstall the shaft in order for pneumatic/hydraulic driven arms to automatically raise it off the ground. It can be loaded directly with a crane, depending on the diameter of the intermediate product. It issues a warning through the coil over the photocell on the main panel. The entire unit is powered by an AC motor.

Groups for Unwinding Unit:

1. Drive Group: This is the group where the belts that enable the coil to rotate are driven.
2. Baller Group: This is the group where the tension of the paper supplied from the coil to the machine is adjusted.
3. Hydraulic Mirror Group: This is the group where the coil is attached to the unit to rotate through the bearings and allows the coil to be shifted left and right.
4. Paper Processing Group: This is the group where the paper is unwound from the coil that is attached to the unit is brought to the exit of the unit.
5. Walking Group: This is the group where there are walking paths that allow access to the points where the coil must have interfered during its placement on the unit.

LAMINATION UNIT

This is the unit through which two separate sheets from the unwinding unit are fed between the lower and upper rubber embossments and the steel embossments, and also, the pattern is imprinted on the paper and a layer of paper is glued on and combined with the other layer for adhesion.

Groups for Lamination Unit:

1. Pressor Group: This is the group where two layers of paper adhere together.
2. Rubber Embossing Group: The group is equipped with rollers that press the paper layers onto the steel embossings, allowing the paper layers to take on the pattern created by the steel embossing.
3. Steel Embossing Group: This is the group where there are cylinders on which the patterns to be embossed on the paper layers are laid up.
4. Baller Group: This is the group where the tension of the paper is adjusted as the glued and adhere layers move from the lamination unit to the next.
5. Dr. Blade Group: This is the group where the glue that will be applied to the paper layers for adhesion is drawn from the glue tank and received by the Anilox roller.
6. Anilox Cylinder Group: Dr. This is the group that contains the anilox roller, which transports the glue from the blade group to the rubber roller through the pores on it.
7. Rubber Glue Cylinder Group: This is the group where the glue on the anilox roller is transferred to the rubber roller by touching one another, and the rubber roller transfers the glue to the paper running on the steel embossing.

REWINDING UNIT

This is the unit that rewinds the paper with the desired qualities on the core and delivers the product. The core can be fed automatically into the continuous paper flow.

The winding unit is capable of winding products with a diameter of 96-155 mm. The coil width differs by the machine specifications.

The Winding Unit mainly consists of the following Groups:

a) Winding Group: This is the group of cylinders on which the desired length of the paper is wound around the core.

b) Breaking Group: This is the group in which the wound product is broken off by breaking shoes.

c) Core Chamber and Conveyor Group: This is the group in which the core is held and transported to the winding area.

d) Perforation Group: This is the group on which the breaking marks on the paper are produced.

e) End-Glue Group: This is the group on which glue is applied on the core.

TAIL SEALER

This is the unit that performs the end-glueing of the rolled product created by rewinding the desired properties of paper onto the core.

The end-glue unit is capable of adhering the products with a diameter of 96-155 mm. The coil width differs by the machine specifications.

Groups for End-Glue Unit:

a) Blowing Group: This is the group in which the log (product) entering the unit is suspended and the winding is opened by blowing air and vacuum.

b) Gluing and Adhesion Group: This is the group where the blown end is glued and adhered to using pressure tapes.

ACCUMULATOR UNIT

Accumulator Unit This is the unit that stores lengthy product logs, dries end glue, and accumulates product in between cutting and winding.

This unit has a maximum production capacity of 300 pieces and a filling capacity of 200 pieces while in operation. The accumulator unit is capable of transporting products with a diameter of 96-155 mm.

LOG SAW

The logs that have been transported from the accumulator unit are cut and trimmed in this machine.

The reliability, flexibility, and ease of use of this machine project are achieved through the employment of advanced mechanical and electronic technologies.

Groups for Log Saw Unit:

a) Entry Conveyor Group: This is a group driven by a servo motor that pushes the product from the accumulator unit to the blade cutting point by propellers and positions it for being cut at the desired length.

b) Cutting Group: This is the group that cuts the product with circular blades in a hatchet motion.

c) Blade Sharpening Group: Circular blade is a pneumatically driven group that grinds the blade diameter down using diamond grinding stones and automatically moves and positions during the reduction of the blade diameter caused by the grinding.

d) Height Adjusting Group: This is the group that enables the blade to be moved up and down according to the diameter of the cutting blade.

e) Neck Group: This is the group that secures the product to be cut and adjusts the winding diameter.

f) Vacuum Group: This is the group where the burrs and dirt generated by the sharpening diamonds are vacuumed away by the blower motor and provide a clean cut.

UNWINDING UNIT 2

This is the unit that unfolds the layers of the coiled paper and feeds it into the machine. It is equipped with two coil suspension arms.

UNIDAD DE DESENROLLADO 2

Esta es la unidad que desdobla las capas del papel enrollado y lo introduce en la máquina. Está equipado con dos brazos de suspensión helicoidales.

CALENDAR UNIT

This is the unit that presses the paper before printing to achieve the desired surface quality.

PRINTING UNIT

This is the unit that uses the flexo printing technology to print on paper.

        CMYK

LAMINATION UNIT 2

This is the unit where two or three layers of paper are glued together and adhered to one another after passing through separate cylinders to take the embossed pattern.

EMBOSSING UNIT

This is the unit where the paper runs through the embossing rollers and is impressed with a pattern before being sliced in half at the exit. (It differs as a set according to the desired product features.)

FOLDING UNIT

This is the unit where the final folding, cutting, and completion of the paper takes place. It is used in either one or two sets. (It differs as a set according to the desired product features.)

TRANSFER UNIT

This is the unit that transports the desired quantity of stacked napkins to the packaging machine

PACKAGING UNIT

This device is used to package folded and cut napkins. It is capable of producing single or double packaging, depending on the customer requirements. This machine is capable of packaging napkins of pre-determined sizes with film coils (PE-OPP-PP, etc.) with a minimum thickness of 20-35 microns.
