Provided in the vicinity of the cutting point of a cutting device that slits a strip into a plurality of strips by a plurality of upper round blades fitted and fixed to the upper rotary shaft and a plurality of lower round blades fitted and fixed to the lower rotary shaft As a prior art of the material pressing device for guiding the belt-shaped material, there are material pressing devices shown in Japanese Utility Model Laid-Open No. 62-88523, Japanese Utility Model Laid-Open No. 1-26211, or Japanese Patent Application Laid-Open No. 7-68411. It has been known.
[0003]
As shown in FIG. 4, the material pressing device disclosed in Japanese Utility Model Publication No. 62-88523 supports an endless belt 25 and the endless belt 25 rotatably at both ends so that the endless belt 25 rotates in a flat shape. This is an endless belt type material pressing device having two sets of rotating rolls 26 and a frame 27 that supports the two sets of rotating rolls 26.
[0004]
Further, the material presser shown in Japanese Utility Model Laid-Open No. 1-261121 is similar to the above-mentioned Japanese Utility Model Laid-Open No. 62-88523 in that the endless belt type material presser has a circulating movement speed of the endless belt. A drive pulley is added to adjust the drive to the same speed as the slitter plate, and the circulating speed of the endless belt that presses the slitted slitter plate can be the same as the slitter plate. As a result, the slipper plate is prevented from lifting while reliably preventing slippage between the circulating endless belt and the moving slitter plate, and a pattern is formed on the surface of the slitter plate by the endless belt that prevents lifting. It is a material presser device that can prevent sticking and wrinkles.
[0005]
Next, as shown in FIG. 5, the material presser disclosed in Japanese Patent Application Laid-Open No. Hei 7-68411 has an upper rotary shaft for the upper and lower rotary shafts 6 and 7 and an upper rotary shaft for the upper rotary shaft.

It is a material presser device with a backup ring that can control the change.
[0006]
[Problems to be solved by the invention]
On the other hand, when slitting a thin belt-like material such as a metal foil or a plastic film, for example, as shown in FIG. 6, the upper round blade 8 and the lower round blade 9 are relatively pushed up and down, and a predetermined amount It is necessary to secure the lap portion T. As a result, the belt-like material 24 entering from the entry side is cut at the intersection X on the entry side of the upper round blade 8 and the lower round blade 9, and the cut belt-like material 24 is respectively adjacent to the upper round blades 8, 8, or It is necessary to open to the intersection Y on the exit side while being sandwiched between the adjacent lower round blades 9, 9, and to be opened between the side surfaces of the adjacent round blades after passing the intersection Y on the exit side. .
[0007]
However, in this series of flows, irregular tension or compression acts on the thin strip 24, and the strip 24 is warped or twisted. As a result, the cut portion of the strip 24 is cut. There has been a problem that harmful defects such as burrs, high edges, and powder fall off occur. Further, in the vicinity of the exit intersection Y between the upper round blade 8 and the lower round blade 9, the belt-like material 24 between the side surfaces of the adjacent two round blades is round as it is sandwiched between the side surfaces of the two round blades. There is also a troublesome problem that the blade is dragged by the rotation of the blade and proceeds in the rotation direction. In order to solve this problem, the intersection X on the entrance side of the upper round blade 8 and the lower round blade 9, that is, between the vicinity of the cutting point by the upper and lower round blades and at least the intersection Y on the exit side, more preferably the upper and lower rounds. Between the vicinity of the cutting point by the blade and a predetermined position beyond the intersection Y on the exit side, the belt-like material 24 follows the outer peripheral surface of the upper round blade 8 or the outer peripheral surface of the lower round blade 9 in a uniform state. Thus, it is known that it is effective to press the belt-like material 24 against the outer peripheral surface of each round blade by the material pressing means.
[0008]
However, when trying to slit a thin strip material such as a metal foil by a slitter equipped with a material pressing device as shown in the aforementioned Japanese Utility Model Publication No. 62-88523 and Japanese Utility Model Publication No. 1-26211 Further, a pair of front and rear rotating rolls for supporting the endless belt in a flat shape, or a pair of front and rear pulleys are provided on both the upper surface side and the lower surface side of the belt material over the entire width of the belt material to be slit. Therefore, it is impossible to move the upper and lower rotating rolls or the upper and lower pulleys up and down until they cross the strip, and the endless belt cannot follow the outer peripheral surface of each round blade. It is impossible to press a thin belt-shaped material along the range of the length on the outer peripheral surface of each round blade with a belt. Slitter provided with a type of material presser device was not suitable for thin strip material slit such as a metal foil.
[0009]
Further, in a shearing device having a material pressing device using a pressing ring as shown in JP-A-7-68411, the belt-shaped material is pressed by a ring made of a rigid body. It is in a line contact state with respect to the outer peripheral surface of the belt, and it is impossible to press the belt-like material along the predetermined range with respect to the outer peripheral surface of the round blade. It could not be used for slits made of thin strips.
[0010]
Also, a material presser that presses the belt-like material by forming a presser ring lined with an elastic body such as rubber on the outer peripheral surface of the presser ring made of a rigid body as disclosed in JP-A-7-68411. Although the device can be considered, in the material presser device having such a configuration, when the elastic body is pressed against the outer peripheral surface of the round blade so that the outer peripheral surface of the round blade is within a certain length range, the elastic body Is compressed in the axial direction, but along with the compression in the axial direction, the outer circumferential surface near the compression part of the elastic ring also causes a pulling deformation in the circumferential direction. Detrimental tension in the direction will act, and favorable results will not be obtained for cuts in thin strips.
[0011]
The present invention has been made in view of the above-described conventional problems, such as a strip material such as a metal foil or a plastic film, or a composite strip material obtained by applying or adhering another substance to the surface of a metal foil or a plastic film, or the like. When cutting a raw material of a thin belt-like material into a plurality of strips with an upper round blade fitted and fixed to the upper rotary shaft and a lower round blade fitted and fixed to the lower rotary shaft, The strip material slit by the lower round blade is the intersection X of the upper round blade and the lower round blade on the entrance side, that is, from the vicinity of the cutting point by the upper and lower round blades to the exit intersection Y, or the upper and lower rounds. From the vicinity of the cutting point by the blade to the position past the intersection Y on the exit side, it can proceed along the outer peripheral surface of the upper round blade or the outer peripheral surface of the lower round blade in a uniform state The strip is secured to the outer peripheral surface of each round blade within a specified range.
