Raising machines


Lafer SpA has become the largest manufacturer of raising and shearing machines world-wide while providing a variety of different solutions for raising all kinds of fabrics whether knit or woven

Double or single drum configuration
Single drum raising machines with 24, 28, 32 or 36 raising rollers and double drum machines with 24, 28 or combined 24/36 raising rollers are available in various widths in order to satisfy different production requirements. Combined raising and shearing units (GLC) are also available.
State of the art controls simplify the raising process
Unlike conventional raising machines equipped with simple control units, Lafer has developed an exclusive system combining both PLC and industrial PC system with large touchscreen colour video with the objective of making raising a much easier process compared to other machines.
Advantages

1 million raising programs storage capacity.

On-screen troubleshooting guide with photos and instructions (over 100 alarms included).

The machine can be connected to a network through ethernet card (optional) so that production data can be monitored from a remote computer.

An optional modem allows troubleshooting directly from Lafer headquarters.

Electronic fancy brush synchro control prevents possible damages to raising fillet caused by non synchronized raising fillet cleaning brushes.
Precise fabric tension control
Fabric tension on the raising drum is one of the key parameters to achieve the desired raising effect. Fabric tension is set on the touch screen and is controlled by the computer.


Automatic minimum tension control by load cells (Patent Pending)
Optional load cells placed at the entry and exit of each drum allow to automatically maintain the minimum fabric tension set regardless of the raising energies. This prevents the fabric from becoming too loose at the drum entry and exit points allowing optimal raising on the entire drum and avoids bar marks, weft distorsions or other inconveniences.

Uniform raising
Special pressure rollers are fitted on the entry and exit draw rollers in order to prevent fabric slippages and ensure perfect raising uniformity.
Adjustable drum speed/direction (standard)
The drum has adjustable speed and can rotate in both directions compared to the fabric. On the twin drum machine drum speed and rotation direction can be varied separately.
Raising energies always constant.
An electronic system maintains the raising energies constant while varying the fabric or drum speed.


Follow the market
Lafer raising and shearing machines are highly versatile as they are designed to allow retrofitting in order to meet the continuous changes in the fashion trends.
