Multifunction coating head
The new Starline RBS is a multi-functional coating head offering on the same station any possible wet coating possibility.
It's designed for both direct and transfer coating operation, then to manufacture artificial leather, coated textiles and other coated materials in bobbin.
With Starline RBS it is possible to apply any kind of solvent based or water based resin (PU, acrylic, silicone, etc) and to work with foamed products.
A rotating turret enables to quickly and easily change the coating system as required by the production requirements of the moment.The coating systems available on the machine are:
- thickness coating over counter-roller;
- "on-air" coating (floating knife) by doctor blade (knife);
- SYNCHRO rollercoating over counter-roller;
- REVERSE rollercoating over counter-roller;
- "on-air" REVERSE rollercoating.
The Starline RBS features a solid monolithic steel frame, welded for an higher torsional rigidity and a turret supporting the roller changing device. The latter can be configured to mount two engraved rollers and one doctor blade (coating knife) or two blades and one engraved roller.
The micrometric adjustment of the coating thickness is motorized, with value digital display on the control panel, and can be set independently right/left or in tandem.
The two drives for the colour doctor blade (one for SYNCHRO operation, the other for REVERSE) are fully pneumatic. The doctor blades themseves are now mounted with auto-aligning supports to assure a perfect alignment and constant uniform pressure over the entire length of the cylinder. This system improves the life duration of engraved roller and doctor blade and a better precision in terms of weight of chemical deposited onto the web. The colour doctor blade, made of extremely rigid steel that guarantees a vibration free action, is provided with an alternative oscillating movement for its cleaning and even wearing out.
Starline RBS is equipped with piping for the resin distribution and engraved roller cleaning at colour change.
All the functions of the machine, controlled by a PLC of the last generation, are located in a large and convenient control panel that can be positioned by the operator.
A wide range of options is available to fit out the machine for the required field of application, such fabric wideners, pumps, rubberised counter-roller and other dedicated accessories.
