A square inch (approximately 10 cm) square is a typical size for each cell.

織物２ａ、３ａか製品ローリング速度で両ローラ１１１５間に滞在する時間は非 常に短いので、ローラ１１からの熱か両織物２ａ、３ａに充分に侵入してこれら を完全に溶融させ、両ローラ１１．１５の圧力及び熱から満足できるシールを形 成できないこともある。このためローラ１９か設けられており、ローラＩ９は、 複合シート２５がローラ１１とローラ２０との間の第２ピンチに入るまで、複合 シート２５を加熱されたローラ１１ど接触した状態に保つことにより熱侵入及び 溶融を生じさせる付加的接触時間を与える。第２ピンチローラ２０は、第１図に 示すように、加熱されたパターンローラ１１及び加熱されないパターンローラ２ １上に支持されている。滑らかなピンチローラ２０の重ｊ力く、ローラ２ｏとロ ーラ１１との間だけてなく、ローラ２０とローラ２１との間にもピンチを形成す る。滑らかなローラ２０の軸３２は側壁５０のスロット３３内で垂直方向に自由 に摺動し、前記ローラ間を通る織物層２ａ、３ａに対して均一な重量を維持する 。装置ｌの反対側は第１図に示す側部と同じであるが、駆動チェーン１８及び軸 上に取り付けられたチェーンスプロケットは設けられていない。破線は機械の側 壁５０のセクションの輪郭を示す。協働するクロス部材及びアタッチメント（図 示せず）を備えた側壁５０は機械ｌのフレームを構成する。ローラ１５．２０の カイトローラ３４．３３は、各側壁に同様に設けられている。シート２５はリブ ５４と接触して加熱されたローラ１１上に載り、シール領域は、／−ト２５が第 ２ピンチローラ２０により形成されるピンチを通過するまで、ローラＩＩの隆起 リブ上に留まる。リブにおけるこの第２の力の付与は、接合ラインすなわちシー ルライン５２ａ、５２ｂにおける接合すなわちノールの形成を肋Ｉ九単−のピン チローラを用いた場合に可能なロール速度及び温度よりも高速のロール速度及び 低いロール温度で機械を作動ｄ１能にする。殆どの場合において、従来よりも高 速及び低温で、充分なノールすなわち接合を形成することかできる。The time the fabrics 2a, 3a spend between both rollers 1115 at the product rolling speed is non-trivial. Since it is always short, the heat from the roller 11 sufficiently penetrates both fabrics 2a and 3a and completely melts and forms a satisfactory seal from the pressure and heat of both rollers 11.15. Sometimes it cannot be achieved. For this purpose, a roller 19 is provided, and the roller I9 is until the composite sheet 25 enters the second pinch between the rollers 11 and 20. By keeping the sheet 25 in contact with the heated roller 11, heat intrusion and Provide additional contact time to cause melting. The second pinch roller 20 is shown in FIG. As shown, a heated pattern roller 11 and an unheated pattern roller 2 It is supported on 1. The weight of the smooth pinch roller 20 is applied to the rollers 2o and 2o. A pinch is formed not only between roller 11 but also between roller 20 and roller 21. Ru. The shaft 32 of the smooth roller 20 is free vertically within the slot 33 in the side wall 50. to maintain a uniform weight on the fabric layers 2a, 3a passing between said rollers. . The opposite side of device l is the same as that shown in FIG. 1, but with drive chain 18 and shaft. No top-mounted chain sprocket is provided. The broken line is the machine side A section of wall 50 is outlined. Cooperative cross members and attachments (Fig. The side wall 50 with a (not shown) constitutes the frame of the machine I. roller 15.20 A kite roller 34,33 is provided on each side wall as well. Sheet 25 is ribbed 54 and is placed on the heated roller 11, and the sealing area is 2. The bump of roller II until it passes the pinch formed by pinch roller 20. Stays on the ribs. The application of this second force on the ribs is due to the joining line or seam. Formation of joints, that is, knolls in the line lines 52a and 52b, with the pins of rib I9. Higher roll speeds and temperatures than are possible with chill rollers. Allow the machine to operate d1 at low roll temperatures. In most cases, higher Sufficient knolls or junctions can be formed at high speeds and low temperatures.

加熱されないパターンローラ２１とピンチローラ２０との間に第３のピンチか形 Ｉ戊される。パターンローラ２１は、これか加熱されない点を除き、パターンロ ー５１１と同一に構成するのか好ましい。パターンローラ２１は、ローラ２１の 隆起リブ５５及び５５ａかシート２５」−に既に形成された接合ラインすなわち シールライン５２ａ、５２ｂに一致するように、パターンローラ１１にタイミン グが合わされる。ロー７７２１は、ローラ冊により形成されたパターンに関して 直接的に、ローラ１１に対する回転関係か調節され、この調節は、ローラ２１の 軸２８のスプロケットｌ　７　ｂを緩め、前記回転調節を行い、且つスプロケッ トを再び前記軸に係止することによって行う。この調節かなされたならば、チェ ーン１８がスプロケット１７ａ、＋７ｂの上及びスプロケット３６の下に掛けら れて緊張され、新しい回転関係か固定される。本機械ｌか採用する正方形すなわ ち矩形のシールパターンの長手方向のシールライン５２ａは、長手方向ノールラ イン５２ａを形成するリブ５４の周方向部分か機械において正確に整合するよう にローラＩＩ、２１を溝方向に位置決めすることにより満足のいくものか得られ る。A third pinch roller is provided between the unheated pattern roller 21 and the pinch roller 20. I will be decapitated. The pattern roller 21 is the same as the pattern roller except that it is not heated. - It is preferable to have the same configuration as 511. The pattern roller 21 is The joining lines already formed on the raised ribs 55 and 55a or the sheet 25'', i.e. Apply timing to the pattern roller 11 so as to match the seal lines 52a and 52b. are combined. Row 7721 concerns the pattern formed by the roller book. Directly, the rotational relationship to roller 11 is adjusted; Loosen the sprocket l7b of the shaft 28, adjust the rotation as described above, and This is done by re-locking the shaft to the shaft. If this adjustment is made, check The horn 18 is hung above the sprockets 17a and +7b and below the sprocket 36. The new rotating relationship is then tightened and fixed. This machine adopts square shape The longitudinal seal line 52a of the rectangular seal pattern is a longitudinal normal line. The circumferential portion of the rib 54 forming the inlet 52a is aligned accurately in the machine. Satisfactory results can be obtained by positioning rollers II and 21 in the groove direction. Ru.

ローラ１９及び、′又はスプロケット３５の調節により、前記横方向の整合に何 ら影響を与えることはない。By adjusting the rollers 19 and ' or sprockets 35, what can be done to said lateral alignment? It has no effect.

冷タイパターンローラ２１とローラ２０との間のピンチの効果は、両織物２ａ、 ３ａの間のシールを固化することである。加熱されたローラ１１との最終接触と 、滑らかなローラ２０．２１の間のピンチとの開を通過するときに、シールを形 成する熱可塑性接合部は、冷却され目、つ充分な物理的強度を得る時間か得られ る。The effect of the pinch between the cold tie pattern roller 21 and the roller 20 is that both fabrics 2a, 3a to solidify the seal between them.

滑らかなローラ２０とパターンローラ２■との間を通過後は、シート２５か完全 なものとなる。ノート２５は堆積粉末１２の盛り上がり状態のために完全な凸凹 状態になる。堆積粉末１２は小さな盛り上がりとして計画的に配置されており、 これにより、堆積粉末の周囲に後で形成されるシールライン５２ａ、５２ｂか、 任意の７−ルから任意の堆積粉末の縁に至る最大距離を維持して、粉末か前記シ ール内に含まれてしまう可能性をなくしている。完成品ロールの保管及び取扱い 性を考虜すれば、ロールをできる限りきつく且つコンパクトにするのか好ましい 。After passing between the smooth roller 20 and the pattern roller 2■, the sheet 25 or completely Become something. Note 25 is completely uneven due to the raised state of deposited powder 12. become a state. The deposited powder 12 is strategically arranged as small mounds, This allows seal lines 52a, 52b to be formed later around the deposited powder; Maintaining a maximum distance from any 7-hole to the edge of any deposited powder, the powder will This eliminates the possibility of being included in the Storage and handling of finished product rolls Considering the gender, it is preferable to make the roll as tight and compact as possible. .

従って、製品のシートの前記凸凹は小さいことか好ましい。Therefore, it is preferable that the unevenness of the product sheet be small.

シート２５は、ピックアップロール２２に近つくときに平板３７上を通過する。The sheet 25 passes over a flat plate 37 when approaching the pickup roll 22.

シート２５は水平に横たわり、平板３７ど接触している。平板３７は、ブラケッ ト４０、ねし４１及び溶接により平板３７に固定された偏心振動ユニット３９に よって振動される。平板３７及びバイブレータ（振動ユニフト）３９は弾性マウ ント３８を介してフレーム５０の所定位置に取り付けられており、弾性マウント ３Ｂはこれらの両取付は端部の間の弾性運動を可能にする。従って、シート２５ は高振動数の振動を受け、これにより堆積粉末１２は、シート２５の各セル５２ のノール５２ａ、５２ｂによって囲まれた領域の全体に亘ってより均一に分散す る。これにより、シート２５はより均一な厚さに薄くなり、巻取りロール（ピッ クアップロール）２２上にきちんと且つコンパクトに巻き上げる適合性を向上さ せる。The sheet 25 lies horizontally and is in contact with the flat plate 37. The flat plate 37 is 40, a screw 41, and an eccentric vibration unit 39 fixed to the flat plate 37 by welding. Therefore, it is vibrated. The flat plate 37 and the vibrator (vibration unit lift) 39 are made of an elastic mouse. The elastic mount 3B, both of these attachments allow elastic movement between the ends. Therefore, sheet 25 is subjected to high-frequency vibrations, which causes the deposited powder 12 to vibrate in each cell 52 of the sheet 25. to more evenly disperse the area surrounded by the nols 52a and 52b of the Ru. As a result, the sheet 25 is thinned to a more uniform thickness, and the sheet 25 is thinned to a more uniform thickness. Improved suitability for neatly and compactly rolling up onto let

巻取り駆動ロール２２の動力は、チェーン１８からスプロケット■７ｃを介して 得ることもてきる。巻取り駆動ロール２２は、実際の製品巻取りロール　２ｇの 駆動手段を提供すべく用いられる。なぜならば、この製造時点には困難な問題が 存在するからである。半塑性複合シートと種々の滑らかなピンチローラとの間の 摩擦は非常に小さい。このため、「オーバーフィード（過剰供給）」の傾向（す なわちパターンローラを通る織物よりも速く製品ブランケットを巻き上げる傾向 ）が生し、これにより、一方又は両方の織物シートか１つ以上の「ピンチ」を通 ってスリップし、１ｌｌＪ的なパターンが破壊されて、粉末がシール領域内に入 る可能性が生しる。また、織物がリブ５４上の加熱された領域において軟化され る間に、横方向シール５２ａにおける成る織物を引っ張る可能性も生じる。逆に いえば、巻取り速度が不充分になり、織物３ａがローラ８の回りを通るときに織 物３ａを緩めてしまう可能性がある。これにより、粉末がキャビティ９から早期 に落下してしまい、シール領域を汚染するため、満足のいくシールか得られな（ なる１、 従って、実際の製品巻取りロール２６は軸駆動形にはてきない。なぜならば、ロ ール２６の直径は絶えず変化し、従って、不安定な「巻取り速度」を生しさせる ことなしにｅｓｕｔ駆斬装置にギア連結できないからである。The power for the winding drive roll 22 is transmitted from the chain 18 through the sprocket 7c. You can also get it. The winding drive roll 22 is an actual product winding roll of 2g. Used to provide drive means. This is because there are difficult problems at this manufacturing point. Because it exists. between semi-plastic composite sheet and various smooth pinch rollers Friction is very small. This has led to a tendency towards "overfeed" (oversupply). i.e. the tendency to roll up the product blanket faster than the fabric passes through the pattern rollers ), which causes one or both sheets of fabric to pass through one or more "pinch" The 1llJ-like pattern is broken and the powder enters the seal area. There is a possibility that Also, the fabric is softened in the heated area on the ribs 54. There is also the possibility of stretching the fabric in the transverse seal 52a during the process. vice versa In other words, the winding speed becomes insufficient and the fabric 3a passes around the roller 8. There is a possibility of loosening the object 3a. This allows the powder to escape from cavity 9 early. This may cause the seal to fall and contaminate the seal area, making it impossible to obtain a satisfactory seal ( Naru 1, Therefore, the actual product take-up roll 26 cannot be of the shaft-driven type. Because, Ro The diameter of the roll 26 changes constantly, thus creating an unstable "winding speed". This is because the gear cannot be connected to the eSUT cutting device without any problems.

しかしなから、常に同一直径であり従って巻き取られた製品シート２６の直径の 如何に係わらず常に同じ供給速度をつくり出すことかできる比較的表面摩擦の大 きいコム表面ローラ２８を介してロール２６を駆動することはできる。ローラの 芯管２３上への捲回を開始し、側壁５０のスロット２４に貫通軸２２を配置する 。ロール２６は小径から大径に成長するであろうが、この間、駆動ロール２７の 表面速度（該速度はローラ８．１１．２１の表面速度に等しい）に等しい一定の 巻取り速度か維持される。機械の生産速度は可変速直流モータ５３の速度を制御 することにより定められる。このモータは、広範囲の負荷に亘って回転速度を厳 格に制御でき、且つ新しい材料の調節を行い且つスレッディング（ｔｈｒｅａｄ ｉｎｇ）を行うへ（、小さな増分で前方に［移動（ｊｏｇｇｅｄ）　Ｊできる。However, since it is always the same diameter, the diameter of the wound product sheet 26 is therefore always the same. Relatively large surface friction that can always produce the same feed rate regardless of the It is possible to drive the roll 26 via the Ki-comb surface roller 28. Laura's Start winding onto the core tube 23 and place the through shaft 22 in the slot 24 of the side wall 50 . The roll 26 will grow from a small diameter to a large diameter, but during this time, the drive roll 27 will grow from a small diameter to a large diameter. a constant speed equal to the surface speed (which speed is equal to the surface speed of the roller 8.11.21) Winding speed is maintained. The production speed of the machine is controlled by the speed of the variable speed DC motor 53. It is determined by This motor has tight rotational speed over a wide range of loads. It is possible to control new material and threading. ing) can be [jogged] forward in small increments.
