PROPF346 – Set up and control multi-knife trimming machinery

Overview

This standard is for print finishers using multi-knife trimming machinery. They will be expected to set up the equipment and control it whilst running production jobs.

This standard consists of two elements:

  • Set up multi-knife trimming machinery
  • Run multi-knife trimming machinery and monitor quality

This is what the standard covers:

  1. identifying the job requirements
  2. checking that the multi-knife trimming machinery is working properly
  3. checking that safety devices are working properly
  4. running the multi-knife trimming machinery safely
  5. adjusting settings, where necessary to maintain the required standard
  6. checking that work meets the required standard
  7. identifying faults and taking action to deal with them
  8. unloading and stacking the finished product

Performance criteria

You must be able to:

Set up multi-knife trimming machinery

  1. check that you have all the job details you need
  2. check that you have enough materials of the right type to meet job requirements
  3. report when materials provided are not correct or sufficient in accordance with organisational procedures
  4. set up the multi-knife trimmer in accordance with organisational requirements, so that:
    1. piles are fed squarely into the trimmer
    2. the clamp holds the pile firmly without marking
    3. piles are trimmed squarely
    4. piles are delivered without damage or distortion
  5. check the trimmed size is within variations permitted by your company
  6. change trimmer knives correctly and safely in accordance with organisational procedures
  7. check that samples produced by the machine match the required standard
  8. make any necessary adjustments to enable the standards to be met
  9. report when standards cannot be met in accordance with organisational procedures
  10. prepare your work area so that it is safe and ready for production

Run multi-knife trimming machinery and monitor quality

  1. run multi-knife trimming machinery so that it is safe, efficient and at the required speed in accordance with organisational procedures
  2. keep up sufficient supplies of materials to so that runs continue as long as necessary to meet job requirements
  3. check that your company's quality standards are met at regular intervals
  4. identify the causes of faults in production, which result in:
    1. unacceptable cut size variation
    2. score marks or shiny glue marks on cut surfaces
    3. ragged cut on bottom pages
    4. book spines splitting at head or tail
    5. books not square or spines creasing
  5. adjust machines, using approved methods and equipment, to correct faults which it is your job to remedy
  6. use agreed procedures to report faults which it is not your job to correct
  7. check that machinery is safe to operate, once faults have been corrected, in accordance with organisational procedures
  8. record the production and quality assurance details, checking information meets organisational procedures
  9. follow the organisational procedures for the removal of waste
  10. stack work using the approved method

Knowledge and understanding

You need to know and understand

  15. the causes of common faults and how to rectify them including unacceptable cut size variation, score marks or shiny glue marks on cut surfaces, ragged cut on bottom pages, book spines splitting at head or tail, books not square or spines creasing
  16. the causes of faults with raw materials, processes and machinery used in your business and how to identify and treat them
  17. techniques for controlling quality including inspection, testing, sampling and use of input and output controls
  18. the impact that faults, in the process you are involved with, have on later processes and the quality of the end product
  19. types of problems that may need to be solved including machinery - electrical, mechanical, electronic, settings, component wear and tear, consumables needing replacement, materials - defects, shortages, incompatibility, systems, organisation and lack of skills or knowledge
  20. sources of information for solving problems including manufacturer's documentation / troubleshooting guides, colleagues, tutors / trainers / mentors and reference material – in house or external, such as the internet
  21. techniques for solving complex problems including changing one thing only at a time and assessing effect of the change, using the problem solving cycle, root cause analysis, brainstorming and visual representations, such as fishbone / mindmap diagrams
  22. techniques for assessing machine faults including observation, listening, inspection of product, reports from colleagues / log reports, touch or smell (if safe to do so) and testing, such as electrical, mechanical, electronic
  23. the types of paper, board and other commonly used substrates including commonly used uncoated, coated, embossed papers and boards

Scope/range

In addition to being able to produce commercially acceptable work, operators should be competent to trim work printed on coated and uncoated stock.

Operators should be able to deal with all running problems within his/her responsibility. Operators are also responsible for ensuring that the machine is in a safe and clean condition for normal production operations.
