Set up and control multi-knife trimming machinery

​

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

​

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:
   piles are fed squarely into the trimmer
   the clamp holds the pile firmly without marking
   piles are trimmed squarely
   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

11. run multi-knife trimming machinery so that it is safe, efficient and at the required speed in accordance with organisational procedures
12. keep up sufficient supplies of materials to so that runs continue as long as necessary to meet job requirements
13. check that your company's quality standards are met at regular intervals

14. identify the causes of faults in production, which result in:
    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

15. adjust machines, using approved methods and equipment, to correct faults which it is your job to remedy

16. use agreed procedures to report faults which it is not your job to correct
17. check that machinery is safe to operate, once faults have been corrected, in accordance with organisational procedures
18. record the production and quality assurance details, checking information meets organisational procedures
19. follow the organisational procedures for the removal of waste
20. stack work using the approved method
