L3214 Laser Cutter User’s Manual
Laser cutting system components 20
2.2 Edge detection unwinder
A motorised unwinder eliminates fabric distortion while cutting by securing a constant and
stable fabric feed onto the cutting bed. As the roll unwinds, a loop is created to relax the
material, reducing distortion, and secure an accurate cut. This loop is kept constant with the
use of the droop sensor or the tension bar.
2.2.1 Safety Information
2.2.1.1 General
The unwinder is used for feeding the laser system with synthetic or natural materials. Using
the unwinder for any other purpose is forbidden. Do not leave any safety covers open when
operating.
WARNING: Frequent heavy lifting and handling of the rolls of fabric can cause back
injuries. Use appropriate lifting and handling tools or ask assistance to reduce this
risk.
Always turn off the unwinder before opening the safety covers or investigating a malfunction.
Only authorised personal may then switch on the unwinder to investigate the problem.
Always turn off the unwinder before opening the electrics cabinet.
Do not move the unwinder when in operation. Space should be kept clear at both ends of the
unwinder to allow for full travel of the upper frame. Do not lean anything against the unwinder.
WARNING: There is a risk of injury from being caught or trapped in moving
machine parts. Keep hands, hair, clothing and jewellery away from moving parts.
Do not wear jewellery, loose clothing, scarves or open jackets or shirtsleeves.
2.2.1.2 Residual Risks
The upper frame of the unwinder travels laterally if required to supply the laser cutter with
fabric correctly. The timing of these movements cannot be anticipated, so great care should
be taken when being around the unwinder during operation. Operator presence is not required
during roll feeding. The lateral travel of the feed mechanism has a limited range.
2.2.1.3 Noise
The noise level does not exceed 70 dBA.
