handling knife blades during the knife change operation
setting up and operating the guillotine for a complex cutting job
checking and adjusting the machine
maintaining the production process
shutting down and/or cleaning the machine
determine information concerning cutting found in the job documentation or production control system, and how to interpret this information to ensure smooth workflow throughout the factory
explain SIX trade terms that may be used in the documentation for complex cutting or guillotine knife change operations
determine elements that must be considered when planning a cutting sequence
identify recommended knife angles for general cutting and the result if the:
knife angle is less than 19 degrees
knife angle is more than 24 degrees
explain the use of a double bevel on a guillotine knife
list factors that indicate a new blade is needed, and the result if a dull blade is used continuously
explain the difference between a sharp knife and a dull knife, and the information to record when a dull knife is replaced
explain when to replace a cutting stick, and the result of not replacing the cutting stick regularly
determine when a knife with a double angle is required
determine forces acting on a guillotine knife
list requirements to choose, and adjust the correct clamping pressure for a given job, and explain the result of the clamp pressure not being appropriate for the stock
identify clamp pressure recommended for:
NCR paper
80gsm offset paper
2400um strawboard
identify the largest and smallest size sheets that can be processed on this machine and the procedures used to complete undersize requirements
determine how to recognise a:
‘work and turn’ job
‘work and twist’ job
‘work and tumble’ job
‘work and back’ job
list problems that can occur when activating the automatic knife, and types of jobs unsuitable for automatic cutting
explain requirements of trimming multi-section books or magazines with bulky spines

list FIVE methods for identifying a lay and gripper edge if not marked
identify reporting procedures if the machine malfunctions
explain treatment/disposal of waste from the guillotine area
list ways to mark lay and gripper edges on sheets, and the result if the lay and grip edges are not recognised
determine need to build-up the clamp of a guillotine, and how to ‘pack-up’ the clamp of a guillotine
identify why:
the guillotine knife will not operate when the machine is turned on
a book block may be cut out-of-square
the program not working after it has been entered into the machine
identify parts of the guillotine to check if, after a cut, top sheets are:
longer than the bottom sheets
shorter than the bottom sheets
out-of-square
creasing along the cut line
list checks necessary when the clamp plate is removed and the machine adjusted
explain factors that indicate a need for machine lubrication, and the correct types and methods of lubrication
determine special operations essential when shutting down the machine
identify maintenance procedures to keep the machine in good condition and order, and methods to rid the machine of waste
list recommended cleaning agents to use on the guillotine
identify quality aspects to consider in a completed cutting job
list steps to ensure important features of the production control system are followed
determine items to check against the client sample (including the cutting result) and the steps required if the result does not coincide with the sample produced
determine areas of the finished product to inspect, and any production alterations required to meet client requirements
identify machine manuals, safety and other documentation relevant to this task, where they are kept, and the information included in them.
