The configuration conditions on both sides are the same for each arrangement of the core material, and wide-spaced parts are formed alternately in the center and both sides, making it easy to cut, have a large tensile resistance, and there is no risk of twisting or deformation, making it a sealing part. This relates to a core material that has great pressure support properties when

る。 This core material is usually a thin metal strip-shaped flat plate about 0.5 mm in diameter, with grooves spaced at equal intervals in the longitudinal direction on both sides.
Two longitudinal holes and one longitudinal hole are drilled alternately in the horizontal direction, and a rubber-like substance such as rubber or plastic is coated with an extruder, and after hardening and molding, breaking is performed. This is a core material for forming a seal component by cutting a short space between the longitudinal hole and the groove in a process and curving it in a direction perpendicular to the longitudinal direction so as to fit into the attachment part as the seal component.
従来薄板からなる細長い帯状の心体は、第1図
および第2図の構成を基本構造とするものであ
る。 The basic structure of a conventional elongated belt-shaped core body made of a thin plate is shown in FIGS. 1 and 2.

ある。 That is, the core body 1 in FIG. 1 has longitudinal holes 2 arranged in parallel with their ends aligned in a direction perpendicular to the longitudinal direction, leaving side widths SW of the same length in the longitudinal direction on both sides. A notch 4 is formed on the side edge at a relative position of 2, and an engraved part 3 is formed between the notch 4 and the elongated hole 2 so as not to penetrate to the back surface.

に湾曲してシール部材を構成するものである。 In this case, in the braking process,
The strips 5 between each other are separated into pieces in the covering rubber. The seal member is curved in a direction perpendicular to the longitudinal direction so that the seal member can be fitted into the mounting portion of the seal member.
第2図は、長手穴2をジグザグ状に設け、側縁
部8の切欠部4と長手穴2との間に、広間部6と
狭間部7を交互に形成してブレーキング工程にて
狭間部7を切断するものである。 In Fig. 2, the longitudinal holes 2 are provided in a zigzag shape, and wide portions 6 and gap portions 7 are alternately formed between the notch 4 of the side edge 8 and the longitudinal holes 2, and the gaps are formed in the braking process. This is for cutting the section 7.
この場合は、切断部が交互に形成されるため、
細片部5はばらばらにならず被覆ゴム中にてジグ
ザグ状に連綴されるものである。 In this case, the cuts are formed alternately, so
The strip portions 5 do not fall apart and are continuous in a zigzag pattern within the covering rubber.
前者の第1図の場合は、次のような欠点があ
る。 The former case shown in FIG. 1 has the following drawbacks.
○イ シール部材製造中に心体に相当な張り力が作
用するため、押出し工程、加硫工程において切
断さればらばらとなる場合がある。B. During the manufacturing of the seal member, a considerable amount of tension is applied to the core, which may cause it to be cut and come apart during the extrusion and vulcanization processes.
○ロ 心体がばらばらにならなくとも、ゴム中に埋
設された心体を一定長に裁断後、ブレーキング
工程に付する事によつてばらばらになるので、
一定長より長くなり寸法的に不安定なものとな
る。○B Even if the core does not fall apart, it will break apart if the core embedded in the rubber is cut to a certain length and then subjected to the braking process.
If it becomes longer than a certain length, it becomes dimensionally unstable.
○ハ 心体がばらばらの状態で、シール部材に引張
り力を掛け、これを所要の一定長に裁断すると
その後収縮により寸法的に不安定な製品しか得
られない。○C If a tensile force is applied to the sealing member while the core body is in pieces and the sealing member is cut to a certain required length, the resulting shrinkage will result in a dimensionally unstable product.
○ニ 完成されたシール部材を所定の箇所に装着す

封部の密封効果にもむらを生じ、また、装着場
所が大きな曲率の場合は密封部分が倒れる。When the completed sealing member is attached to a specified location, uneven tensile force occurs in the longitudinal direction, causing uneven sealing effect of the sealing part, and if the attachment location has a large curvature, the sealing part may collapse.
○ホ この心体は、貫通打刻部と非貫通打刻部を形

生が多い。○E This center body forms a through-embossed part and a non-through-embossed part, and is stretched both vertically and horizontally by pressing and stretching, and the through-embossed part is opened to form a longitudinal hole 2, and the side width is Since the SW portion is formed to have a particularly thin thickness, cutting defects at the stamped portion often occur during this pressing and stretching process.
以上の欠点を勘案し、ばらばらにならないよう
に、非貫通打刻部を無くする必要があり、その構
成が第2図の例である。 In consideration of the above-mentioned drawbacks, it is necessary to eliminate the non-penetrating embossed portion in order to prevent it from falling apart, and the structure thereof is shown in an example in FIG.
第2図の例示の心材は、側縁部8と長手穴2と

らにシール部材の円滑な湾曲性が得られない欠点
をも有するものである。 The exemplary core shown in FIG. 2 has wide portions 6 and narrow portions 7 alternately formed between the side edge portion 8 and the longitudinal hole 2;
It has a structure in which the cut portion is obtained by forming the gap 7 near the side edge 8, and stress concentration is not obtained in the cut portion during the braking process, so the cut portion is not easily cut and requires a considerable number of braking cycles. Moreover, the number of times of cutting is also variable and varies widely, and there is a drawback that the adhesion between the covering rubber and the core body is reduced by the time it is completely cut, and the rubber is seriously damaged. It also has the disadvantage that it does not provide good performance.
因つて、考案者らは、探究の結果、容易に切断
し且つブレーキング回数のバラツキが少なく集中

接着力の低下の少ない、引張り抗力が大きく均等
で、各工程において捩れ変形の虞れがなく、心材
としての支持強度の大なる心材の構成を得たもの
である。 Therefore, as a result of research, the inventors found that it is easy to cut, the number of braking cycles is small and the cutting is concentrated, and the tensile resistance is large and uniform, with less damage to the covering rubber-like material and less decrease in the clamping adhesive force. In this way, there is no risk of twisting and deformation in each process, and the core material has a high supporting strength as a core material.

応じて適宜に色色な変形曲線が考慮される。 This core material for seal parts is provided with grooves having curved tips of the same height in the width direction on both sides of a thin metal strip plate, arranged in parallel at equal intervals in the longitudinal direction, and grooves facing each other in the width direction. In between, rows with two longitudinal holes drilled and rows with one longitudinal hole drilled in the horizontal center are provided alternately in the longitudinal direction. A short spaced part is formed between the mutual curved tips of the groove part and the longitudinal hole, and a wide spaced part is set between the central longitudinal hole at the center of the width and the groove parts on both sides, The short distance is between the mutually curved tips of the groove and the elongated hole, so that it is very easily cut during the braking process.
The cross-sectional area is made as small as possible, and the area near the short distance is formed by connecting the upper and lower covering rubber-like materials to strongly sandwich and hold it elastically. The bending stress that is repeated during the cutting process is concentrated, and the rubber-like material is used to elastically support the material even after cutting, and the cut portions are formed symmetrically on both sides of the same arrangement, and the uncut portions are connected. Widely spaced parts are formed alternately in the center and on both sides, so that the tensile resistance is uniform and large.
It constitutes a core material that has a large supporting capacity as a core material and is highly stable without the risk of twisting or deformation.
Note that the shapes of the curved tips of the grooves and the elongated holes are not limited to those shown in the drawings of the embodiments, and suitably colored deformation curves may be considered as necessary.
次に、実施例に示す例示の図面に基づいて、こ

の大なる特徴を有するものである。 As described above, in the core material for sealing parts of this invention, since the short interval parts SI are formed on both sides of the straight line in the same arrangement, the repeated bending operation in the braking process can be easily and smoothly performed. The bending stress is concentrated on both short-spaced parts, and the number of times of braking is reduced to prevent damage to the rubber-like material and a decrease in the clamping and covering force. Because it is formed, the tensile resistance is large and uniform, there is no risk of twisting or deformation in the manufacture of seal parts, and it is extremely stable, and it also has great support as a core material. .
