When cutting paper and cardboard, dust and jagged edges can affect cleanliness, presentation, and subsequent operations. Knives for paper and cardboard must be selected depending on the machine and the type of work: longitudinal, transverse, guillotined or slotted cutting. Each operation requires its own geometry and assembly.
Separate defects by operation
Do not mix longitudinal cutting powder with guillotining defects in the same diagnosis. Keep samples identified by machine, tool and material. Record weight or structure, coatings and variation between lots. If the defect appears only with one product, examine its characteristics and processing conditions before changing all blades.
Check edge, support and transportation
A uniform cut requires that the material arrives stably and that the cutting elements work according to their design. Inspect supports and complementary parts according to the manual. Kanefusa has different tools for paper conversion, including slitter and guillotine; The manufacturer’s information should be consulted for the corresponding application.
Organize sharpening control
Identify each set and write down the dimensions after intervention. Maintain acceptance criteria for edge, finish, and cut quality. Do not modify angles or minimum dimensions without technical approval. The number of sharpenings is not enough to decide a recall: the condition of the part, the remaining geometry and the service limits matter.
Information for a spare parts consultation
Send make and model, reference, plan, measurements and assembly photographs. Add samples of the defect and describe the specific operation. Avoid requesting a tool solely by industry name. When comparing alternatives, measure accepted product between changes, associated cleaning and duration of interventions, in addition to the life of the edge.
Frequently asked question
Does more pressure always improve the edge?
A defect must not be compensated for with changes outside the authorized parameters. Determine the cause and use the appropriate settings for the equipment and material.
