These disc knives have the advantage of being easy to manufacture and requiring only radial polishing.

定がなされている。 A flat disc knife and a concave circular knife ground into a saucer shape are each clamped onto a cutter shaft by a ring which determines the spacing of the knife blades. These rings abut each other by their sides in their small-diameter areas, and the disc knife is inserted into the groove or recess between these rings and is pressed against the collar of the groove wall by means of washer-type worm springs or cup springs. (1a)
(see Figures and Figure 2a). These springs counteract the spring pressure when the entire disc knife is pressed against the wall of the recess as a rigid member and both cutter shafts, each with a disc knife and a grooved knife, are tensioned axially against each other. The dimensions are such that it can be lifted more or less from the wall of the recess.

The disc knife houses an inner peripheral portion of a cup spring having a spring force capable of biasing the other side surface of the disc knife radially outward from the circular edge and deforming the disc knife into a saucer shape, and protrudes from the cup spring. The outer peripheral portion of the counter knife is characterized in that it comes into surface contact with the counter knife due to elastic deformation.

Such a saucer-shaped deformation can also be obtained by applying a spring or cup spring force to the disk knife. The spring is inserted between rings pressed together on the cutter shaft. The pressure of the spring and the thickness of the disc knife are adapted to each other in such a way that the disc knife assumes a saucer-like or cup-like shape by elastic deformation.
That is, the disc knife 1 is clamped between the rings 5 pressed together on the cutter shaft 3, and the disc knife 1 is placed in the recess 7 formed by the step on the side of the ring 5. The cup spring 13, which springs the disc knife 1 into engagement with the side surface of one ring 5, is recessed 7.
the cup spring 13 has an outer diameter (DTellerf) larger than the diameter of the ring 5;
In a slitter for longitudinal cutting of a web of film material, which comprises at least one clamping device for clamping a flat disk knife 1, the disk knife 1 is not only elastically pressed against the side surface of one ring 5; so that the portion beyond the edge 17 of the ring 5 is elastically deformed in the axial direction,
The spring pressure of the cup spring 13 and the thickness 15 of the disc knife 1 are mutually adjusted.

A flat disc knife 1 and a polished concave circular knife 27 are respectively mounted on top. knife 1 is seated between and on rings 5;
Adjacent ring 5 by inserted cup spring 13
is pressed against the side of the During operation of the cutter, the disc knife 1 and the grooved knife 19, which is a counter knife, are moved into engagement with each other, and the cutter shaft 3 is biased in the axial direction with respect to the counter cutter shaft 21.
Conventionally, the cup spring 13 and the disc knife 1 have been mutually adjusted in such a way that in this step the disc knife 1 as a whole is lifted out of its abutment against the ring 5 (see FIG. 1b). In extreme cases, both knives assume an undesirable position relative to each other, as shown in FIG. 1c as a point of contact 29 between the cutting edge of the groove knife 19 and the side surface of the disk knife 1.

This knife has an arcuate cross section. The force, the material of the blade, and the amount of deflection of the disc are selected such that the disc knife recovers its flat shape when the force is removed. In this way, the advantage of being able to radially resharpen the entire pack of adjacent disk knives is retained.

たわみ得るように選択される。 FIG. 4 shows a clamping device which allows a saucer-like or cup-like deformation of the disc knife 1 only by means of rings 5 pressed against each other. Therefore, all rings 5 are formed in the same shape. Circular edges 9 and 11 with diameters d and D, respectively, cause elastic deformation of the flat disc knife 1. The width and depth of the groove 7 are selected such that the disc knife 1 can be freely deflected.

し0.5mmの厚さを有する。 The disc knife is tightened only along the two circular edge portions 9, 11 of the two adjacent rings 5;
The intermediate space of the recess 7 also has dimensions such that the disk knife 1 is elastically deflected in the axial direction. Precisely, the desired flexural deformation of the disc knife 1 is obtained by the dimensions of the circular edges 9 and 11 corresponding to FIG. 4. The disc knife 1 has a thickness of 0.4 to 0.5 mm.

変形を部分的に解除することができる。 The dashed line in FIG. 4 shows the relationship between the disc knife 1 and the grooved knife 19 in the cooperative state. Since the disc knife 1 remains in contact with the circular edges 9 and 11, the grooved knife 1 remains in contact with the circular edges 9 and 11, as in the case of the concave circular knife shown in FIG. 2c.
9 is obtained. of course,
In this case, by tensioning the cutter shafts 3 and 21 in the axial direction, the saucer-like deflection deformation of the disc knife 1 can be partially released.

す部分は作動状態を示す。 Further, due to the stepped shape of the ring 5 shown in FIG. 5, a safe and accurate mounting state can be obtained when the disc knife 1 is clamped by the cup spring 13 and the ring 5 on the cutter shaft 3. In the case of the conventional clamping device shown in FIG. 1a, if a small inadvertent event causes the ring 5, the disc knife 1 and the cup spring 13 to align, the disc knife 1
may enter between ring 5. This makes it impossible to press the rings 5 flat against each other. In the case of Fig. 5, even if each member is loosely assembled, the disc knife 1 has a diameter of
reliably centered on the stage of ring 5 with dSch,
The cup spring 13 is also mounted on its own ring stage. The disc knife 1 is received in a recess 7 formed by a step on the side of the ring 5 which is much wider than its thickness, whereas the cup spring 13 is formed in the adjacent ring 5 and is received in a recess 7 which is much wider than its thickness. It is seated on a step 23 having a diameter larger than the inner diameter dSch of 1. Further, the portion indicated by the broken line in FIG. 5 indicates the operating state.
