The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the following is essential:

correctly set up trimming machines according to job specifications and within the production timeframe

demonstrate an ability to find and use information relevant to the task from a variety of information sources

demonstrate all safety devices on the machine

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

on TWO occasions using: different grammage or thickness of section or books AND different size alterations (eg A4 to A5)

apply these operations according to manufacturer's and job specifications, enterprise procedures and the listed Performance Criteria

demonstrate use of computerised control, monitoring and data entry systems if available and appropriate.

Context of and specific resources for assessment

Assessment must ensure:

assessment may take place on the job, off the job or a combination of these

off the job assessment must be undertaken in a closely simulated workplace environment.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct questioning combined with review of portfolios of evidence and third party workplace reports of on-the-job performance by the candidate.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

ICPSU202C Prepare, load and unload product on and off machine

ICPSU207C Prepare machine for operation (basic).

Required skills

OHS in relation to operating machinery

communication skills to read job specifications and to complete workplace documentation

organising such as laboratory testing and preparing materials and equipment for production

working in a team by maintaining the production process in association with others

using technology setting up the machine for cutting and trimming

problem solving by setting up and adjusting delivery system according to job specifications

Required knowledge

information that should be found on a job ticket or production control system

OHS factors that must be considered when handling knife blades during the knife change operation

safety devices that must be used when replacing trimmer knives

knives transportation to and from the machine

recommended knife angles for the trimming machine

factors that indicate a new blade is needed

the effect of continually using a dull blade

identifying a sharp knife from a dull knife

the need to replace a cutting stick

OHS factors that must be considered when setting up transportation systems

belt timing readjustment

adjustments to ensure book is fast against book stops

book transport speed determination

adjustment if the book is out-of-square

adjustment if the book is scratching or "scuffing"

OHS factors that must be considered when setting up three-knife stacking systems

danger areas that exist at the delivery end of the book trimming machine

problems that can be expected in the delivery area of the machine

batching device activation

OHS factors that must be considered when setting up the trimming unit

machinery safeguards that are to be considered when setting up the trimmer

clamp pressure determination for each job

what evidence indicates that the clamp pressure is insufficient

the need to replace the knives

important elements that must be considered when moving knives to suit a different size book

machine adjustments to remove more offcut from the fore edge of the book

machine adjustment to remove more offcut from the head and tail of the book

important elements that must be considered when moving knives to suit maximum/minimum size

correcting the following problems: 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

machine manuals, safety and other documentation that are relevant to this task, where they are kept and information that is included in these documents

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Cutting process may include:

single or multiple knife, manual or programmable 3- or 5-knife trimmers and spine trimmers.

Cutting units may include:

range of semi-automated, automated or computerised 3- or 5-knife trimmers and spine trimmers.

Substrate types may include:

range of substrates within the major categories of paper, pressure sensitive material, board, plastics.

Substrate handling may include:

large or small sheet handling systems.
