Application
This unit of competency covers the skills and knowledge required to set up and operate spun bond web forming machines used to manufacture non-woven textiles.
The unit of competency covers the skills needed for initial start-up and product changeovers of spun bond web forming machines, including machine settings, first-off runs and adjustments.
Work may be conducted in small to large scale enterprises and may involve individual and team activities.
No licensing, legislative or certification requirements apply to this unit at the time of publication.

Evidence of Knowledge
Evidence must be provided that demonstrates knowledge of:
safe work practices and procedures and use of personal protective equipment (PPE)
relevant Australian Standards
operational variables, including:
polymer throughput
air throughput
spinneret configuration (hole size and distance to collector)
spinning, drawing and deposition options and techniques

Assessment Conditions
Assessors must:
satisfy the assessor competency requirements that are in place at the time of the assessment, as set by the VET regulator
have vocational competency in setting up and operating a spun bond web forming machine, at least to the level being assessed, with relevant industry knowledge and experience.
Assessment should occur in operational workplace situations. Where this is not possible, or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment reflecting realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
Foundation Skills
This section describes those required skills (language, literacy and numeracy) that are essential to performance.
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
