Evidence of Performance
Evidence of the ability to:
correctly set up in-line bottom making machines for the manufacture of sacks or bags in accordance with job specifications, performance criteria, and with minimum downtime.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
list common faults associated with folder gluer machines, the causes, and methods to correct them
explain correct set-up procedures to meet work health and safety and enterprise requirements
explain the procedure for blade setup.
Assessment Conditions
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the converting, binding and finishing field of work and include access to scoring, folding, and gluing machinery used in the manufacture of sacks and bags.
Assessors must satisfy NVR/AQTF assessor requirements.
