Application
This unit describes the skills and knowledge required to set up 3- or 5-knife trimmers or spine trimmers, and may involve gathering (collating) and fastening.
It applies to individuals who work under direct supervision with some accountability for the quality of outcomes.
No licensing, legislative or certification requirements apply to this unit at the time of publication.

5. Set up machine for trimming | 5.1 Trimmer knives are set up and adjusted according to job specifications 5.2 Clamping pressures are set up and adjusted according to job specifications 5.3 Stops and lays are set to remove desired trim |
6. Conduct sample run | 6.1 Material to be used for sample is organised correctly 6.2 Machine is set up and operated to produce a specified sample according to work health and safety requirements, manufacturer’s specifications and enterprise procedures 6.3 Sample is visually inspected and/or tested or laboratory testing is organised according to enterprise procedures 6.4 Results are interpreted to determine adjustment requirements 6.5 Adjustment changes are carried out according to product and machine specifications |
Evidence of Performance
Evidence of the ability to:
correctly set up trimming machines according to job specifications and within the production timeframe on TWO occasions using different grammage or thickness of sections or books, and different size alterations (e.g. A4 to A5)
demonstrate all safety devices on one of these machines:
book block trimmer or single section copy trimmer (3-knife section gather/stitch/trim)
OR
single section copy trimmer (1- or 3-knife multiple flat sheet gather/fold/stitch/trim)
OR
5-knife trimmer.
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:
explain information found on a job ticket or production control system
identify work health and safety factors that must be considered when:
handling knife blades during the knife change operation
setting up transportation systems
setting up three-knife stacking systems
setting up the trimming unit
explain how trimmer knives should be transported to and from the machine and the safety devices to use when replacing trimmer knives
identify danger areas at the delivery end of the book trimming machine and machinery safeguards for setting up the trimmer
list factors that indicate:
a new blade is needed
a cutting stick needs to be replaced
knives need to be replaced
explain important elements to consider when moving knives to suit a different size book and when moving knives to suit maximum/minimum size
list recommended knife angles for the trimming machine
describe what can occur if a dull blade is used continuously
explain differences between a sharp knife and a dull knife
explain when belt timing readjustment is required
identify what determines book transport speed, and adjustments required to ensure book is fast against book stops
explain adjustments required when the book is:
out-of-square
scratched or scuffed
explain how the batching device is activated
identify problems expected in the delivery area of the machine
explain how clamp pressure for each job is determined and the evidence that indicates clamp pressure is insufficient
determine machine adjustments required to remove:
more offcut from the fore edge of the book
more offcut from the head and tail of the book
explain how to correct these:
book out-of-square
book scuffing
wrong sections
incorrect cover creasing
wrong wire stitch positions
wrong sheet/section sequence
wet ink problems
book spines bursting
waste not transferring from cut line
identify areas to check on the final job sample
identify machine manuals, safety and other documentation relevant to this task, where they are kept, and information included in them.
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 special purpose tools, equipment and materials.
Assessors must satisfy NVR/AQTF assessor requirements.
Foundation Skills
This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.
