Shearing machines

EXCLUSIVE HIGH PERFORMANCE CONFIGURATION


The"Diablo" version allows to shear polar fleece and terry velours up to double the speeds of conventional machines with completely automated adjustments



The know-how developed while serving the most qualified Companies worldwide has lead to today’s wide range of machines that can operate independently or in modular lines for shearing and raising/shearing customised according to different fabric structures and production requirements.

Exclusive anti-vibration shearing cylinder
The Lafer shearing cylinder is of a unique design, with a special anti-vibration technology, that ensures a perfect rotation in order to achieve an optimal cut. The cylinder revolves at a speed adjustable from 500 to 1500 rpm.

The Diablo shearing machine, presented in 2004, significantly improves the standard of shearing performance and quality.

Maximum shearing precision
The shearing precision on the Lafer machine is 0.03mm, whereas most other machines have a precision of only 0.1mm. This increased precision, gives a great advantage of much better control and a better shearing effect and quality.


Automatic shearing and velveting height control based on the fabric thickness
This device (available on request) optimises shearing by ensuring always the same pile height regardless of the actual thickness of the fabric.
Sensors continuously monitor the fabric thickness(sensitivity 0.03 mm) and the shearing and velveting parameters are automatically adjusted when the seam passes by adding the degree of shearing and velveting to the fabric thickness.


Shearing rest & ledger blade alignment
The alignment of the shearing rest & ledger blade is maintained constant when the shearing height is varied thanks to the particular “compass” movement.


Automatic fabric tension control
The fabric tension set between the draw rollers is automatically monitored by highly sensitive load cells hence it is possible to shear in continuous mode and with minimum tension every kind of woven, knit and stretch fabrics.
In order to prevent the fabric from slipping or dragging on the velveting brush when a strong action is set, the 2 draw rollers have a wide contact angle of the fabric to ensure the correct grip.


Automatic lubrication
It is critical to maintain the shearing cylinder evenly lubricated in order to ensure uniform shearing and the Lafer offers maximum reliability. The Lafer system can be programmed how often to oil the felt and how much oil is to be distributed. When the oil finishes the computer will give an alarm.


PC based machine management system
Lafer automated the functions of the shearing machine before any other maker and has and has continuously introduced innovative solutions to make operation easier and more efficient.


All functions are under control
The Lafer shearing machines are driven by AC motors controlled by sensorless vectorial inverters and the electronic control system is equipped with:

PLC programmable logic controller for the machine automations and alarms.

Operator interface by industrial PC using colour touch screen technology for setting and storing all operating parameters. Shearing parameters of each fabric can be memorised (over 1 million recipes can be stored) hence the desired effects can be easily and quickly reproduced.
