Nippol Roller – The Latest Technology for Calendering Process

The continuously evolving demands of the industry have driven innovations and advancements in the calendering process. Nippol Roller equipped Polteks Touche Nip-Pro Calender Machines ensure extremely precise operation thanks to hydraulic oil actuated pistons located inside the roller. This precision enables the system to deliver flawless pressure even at low working pressure values.

Nippol – I Roller Technology

Creates a rigid nip pressure line against the counter roller on the entire width. With its unique design, the precise pressure generated by the piston caps inside the Nippol Roller ensures consistent performance throughout the entire operation.

• Working area can be adjusted according to the fabric width.
• Precise operation at all linear pressure values ranging from 25 to 450 N/mm.
• Long-term operation without oil leakage thanks to the specially designed sealing system.

Nippol – II Roller Technology

Unique design allows you to adjust pressure independently on both nips with piston caps inside the roller which can generate pressure to both sides. Nippol – II Roller can be retrofitted to the I type machine frames easily.

• Independent pressure values can be achieved on top and bottom nips.
• Working width can be selected to avoid edge wear and burns.
• Uniform linear pressure on the entire width against both the upper and lower rollers.

Touche Nip-Pro with InLine Air Permeability System

Allows the user to continuously monitor the air permeability value of fabric as it moves through the entire width of the fabric. According to the air permeability value of the fabric, the machine automatically adjusts its parameters to ensure consistent air permeability. The key advantages of this system are its ability to perform realtime measurements without frequent production stops and its capacity for automatic adjustments during operation.

Individual Zone Controlled Nippol Roller

With the individual zone controlled Nippol system, different pressure values can be created in different places of the roller. It is possible to send oil with different pressures to these zones, each supplied by a separate oil line. This system works simultaneously with our recently developed air permeability control unit, continuously adjusting the zone pressure based on the air permeability values measured from different areas of the fabric.
