LAB SPINNING EQUIPMENT
BSL
This bench spinning line is designed for laboratory R&D spinning tests on different type of spinning polymer solutions (called dopes). It is suitable for both Wet Spinning or Air Gap (Dry Jet) methods.

PISTON SPINNING HEAD
The Piston Spinning Head consists in:
- One cylinder containing dope (dope can be also in
a pre-filled cartridge). - One cylinder (or cartridge) housing heated.
- One piston that presses the dope contained in the cylinder.
- One spin pack with a spinneret, where dope is extruded in filaments.

COAGULATION BATH
The coagulation bath is designed to be suitable for both Wet Spinning and Air Gap Spinning configurations:
- Wet spinning is performed if the spinneret is immersed into the coagulation bath;
- Air gap spinning is performed if the spinneret is above the coagulation bath.
Coagulation bath solution is recirculated by means a pump.

WASHING ROLLS STANDS
The washing rolls are adjustable in inclination, to allow a multiwrap lacing.
The washing of the fiber is performed by feeding (hot) water on top of the rolls.
The excess of washing water is collected in a basin just underneath the washing rolls.

HOT ROLLS STAND
Hot rolls are suitable for fiber drying or heat setting.
The hot roll can tilt along vertical axis and horizontal axis.
A special support box makes hot rolls modular: multiple rolls can be installed on a stand in different configurations.

WND
WINDING MACHINE
The speed control of the winding machine can be performed in the following way:
- By operator input, when used as a stand-alone machine;
- By setting the same speed of last upstream roll, if integrated in the bench spinning line.
CONTROL SYSTEM
- Each unit of the bench spinning line can be controlled with any device which is running a browser compatible with HTML 5.
- This device should be connected via Ethernet to the controller.
The control page, or control screen, collects all the commands and the actual status of units, such as the speed of the rolls, the status of the machine, the presence of errors and the current output.
