Description of the Related Art Conventionally, as a clamping device used for cutting a sheet material such as a rubber sheet, as shown in FIG. 8, a plurality of pressing pieces are formed by forming slits at a predetermined pitch in a width direction of a sheet material a. A sheet material a is pressed against a receiving plate portion d by a holding plate c made of a spring steel thin plate formed with portions b... In some cases, the material a was configured to be cut.

ものである。SUMMARY OF THE INVENTION In order to achieve the above object, a sheet material clamping apparatus according to the present invention comprises an upper receiving plate, and an upper and lower plate which can be approached and separated from below. And a pressing portion for pressing the vicinity of the cut portion of the sheet material on the receiving plate portion, wherein the pressing portion is made of a cloth-like body curved in a mountain shape toward the sheet material side in a side view. A first pressing member and a second pressing member are provided, and the receiving plate portion is
A first receiving member having a horizontal receiving surface above the first pressing member;
A plate piece and a second receiving surface above the second pressing member
A second receiving plate, and the first receiving plate and the second
And between 2 receiving plate piece and the first pressing member between the second pressing member is obtained by attaching a movably cutter to cut.

のとき、第１押圧部材と第２押圧部材は、シート材の厚
みやプロファイルの変化に対応して弾性変形しつつシー
ト材を幅方向にわたって略均一な力で押圧する。When the first pressing member and the second pressing member are brought closer to the receiving plate, the sheet material is pressed against the receiving plate. At this time, the first pressing member and the second pressing member press the sheet material with a substantially uniform force in the width direction while elastically deforming in accordance with the change in the thickness and profile of the sheet material.
【０００８】第１押圧部材と第２押圧部材の間のシート
材にカッターが切り込まれるため、切断部の前後両辺が
固定された状態となる。このため、カッターによる切断
抵抗があってもシート材の位置ずれが防止される。[0008] Since the cutter is cut into the sheet material between the first pressing member and the second pressing member, both front and rear sides of the cut portion are fixed. For this reason, even if there is a cutting resistance by the cutter, displacement of the sheet material is prevented.

１押圧部材と第２押圧部材が自然に離れる。Since the first pressing member and the second pressing member are made of a cloth, the first pressing member and the second pressing member do not adhere to the sheet material. Therefore, when the first pressing member and the second pressing member are separated from the receiving plate portion after cutting, the first pressing member and the second pressing member naturally separate from the sheet material.

る。As a result, as shown in FIGS. 5 and 6, the first pressing member 5 and the second pressing member 6 of the pressing portion 3 are formed by the elasticity of the material (cloth) and the thickness of the sheet material 2. It elastically deforms in response to changes in the profile. Therefore, before and after the cutting portion B of the sheet material 2, the first receiving plate piece 12 of the receiving plate portion 1 is moved.
And the first receiving plate piece 13 and the first holding portion 3 below it.
The pressing member 5 and the second pressing member 6 can be fixed (clamped) by pressing with substantially uniform force in the width direction.

ても、シート材２が位置ずれすることはない。Thereafter, the cutter 14 is advanced from one end in the width direction of the sheet material 2 to the other end, and the sheet material 2 is cut in the width direction. At this time, since the sheet material 2 is fixed as described above, the sheet material 2 is not displaced even if there is a cutting resistance by the cutter 14.
【００２６】従って、図７に示すように、シート材２に
生じる切断面15, 15を、平面的に見て直線状とすること
ができ、正確な切断が可能となる。Therefore, as shown in FIG. 7, the cut surfaces 15, 15 formed in the sheet material 2 can be made linear when viewed in plan, and accurate cutting can be performed.

ものでも、直線的に切断できる。In the illustrated example, the sheet material 2 is composed of an inner liner 16 and chafers 17 and 17 provided along both ends of the inner liner 16 (see FIGS. 2 and 6). In addition to this, it is possible to cut linearly even an inner liner whose thickness gradually changes along the width direction as shown in FIG.

下流側へ搬送する際の送りミスを防止できる。After cutting the sheet material 2 as described above, the holding portion 3 is lowered. At the time of this lowering, the pressing portion 3 naturally separates from the sheet material 2. That is, since the first pressing member 5 and the second pressing member 6 of the holding portion 3 are made of a cloth, the sheet material 2 is formed from the structural characteristics of the cloth and the like.
Does not stick to. Therefore, it is possible to prevent a feeding error when the sheet material 2 is subsequently conveyed to the downstream side.
