Title:
SLITTER DEVICE
Document Type and Number:
Japanese Patent JP2023166172
Kind Code:
A
Abstract:
To disclose one example of slitter devices which can cut a sheet-like cutting-target, appropriately by a slitter blade.SOLUTION: A slitter device 1 comprises: a first roller 3A and a second roller 3B which come in contact with a cutting-target fa and rotate thereby transporting the cutting-target fa; and a cutter 5 having a slitter blade 5B which cuts the cutting-target fa, in a direction parallel to a transportation direction. The second roller 3B arranged at a downstream side in the transportation direction of the cutter 5 rotates at a circumferential velocity larger than a circumferential velocity of the first roller 3A arranged at an upstream side in the transportation direction of the cutter 5. Consequently, tensile force parallel to the transportation direction is generated in the cutting-target fa by difference between circumferential velocity of the first roller 3A and that of the second roller 3B, the cutting-target fa can be therefore cut appropriately by the slitter blades 5A and 5B.SELECTED DRAWING: Figure 1
