Elements and Performance Criteria

1. Prepare for job
   • Job specifications are read and interpreted from job documentation or production control system
   • Set-up is carried out correctly in minimum time with minimum wastage
   • Availability of all job related components is checked
2. Install and replace cutting knives into machine
   • Appropriate knives are selected and secured to the machine
   • Dull blades are securely bolted into protective holder
3. Set up section transportation system
   • Feeder is set up and adjusted according to job specifications
   • Section pick-up and transportation system is set up and adjusted according to job specifications
   • Transfer systems are set up and adjusted according to job specifications
4. Set up stacking system
   • Delivery is set up and adjusted according to job specifications
   • Section transfer and control system is set up and adjusted according to job specifications
5. Set up machine for trimming
   • Trimmer knives are set up and adjusted according to job specifications
   • Clamping pressures are set up and adjusted according to job specifications
   • Stops and lays are set to remove desired trim
6. Conduct sample run
   • Material to be used for sample is organised correctly
   • Machine is set up and operated to produce a specified sample according to work health and safety requirements, manufacturer’s specifications and enterprise procedures
   • Sample is visually inspected and/or tested or laboratory testing is organised according to enterprise procedures
   • Results are interpreted to determine adjustment requirements
   • Adjustment changes are carried out according to product and machine specifications

Performance Evidence

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.

Knowledge Evidence

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.
