Description
本発明は負圧によって穿孔支持体上に適所に保持されている繊維体の圧縮方法、及び前記方法を実施するための装置に関する。
おむつ、失禁パッド、衛生ナプキン、パンティライナーの如き吸収物品の製造では、超吸収剤、結合繊維又は他の材料の添加あり又はなしで毛羽パルプが吸収層として使用されることが一般的である。毛羽パルプはマット成形機などに供給され、所望の形状を与えられる。成形されたパルプ体は次に圧縮されて所望の吸収特性を得る。パルプ体はしばしば穿孔された搬送トラックに搬送され、負圧によって搬送トラック上に適所に保持される。吸収物品の製造のための連続的プロセスラインの場合には、多数の個々の吸収体又は吸収材料の層はしばしば表面層材料の走行ウェブ上に押し出される。そして、個々の吸収体又は層が走行ウェブ上の正しい場所に到ることが製造の正確さのためにはもちろん最も重要である。
本発明によれば、この目的は以下の方法によって達成される。即ち、負圧によって穿孔支持体上に適所に保持されている繊維体の圧縮方法において、圧縮されるべき各繊維体が最初に第一支持体上に配置され、前記第一支持体が繊維体によって被覆される領域内に穿孔を有する部分及び穿孔を有さない部分を含むこと、繊維体の第一圧縮が第一支持体の穿孔を有さない部分(単数又は複数)を被覆する繊維体の部分において行われること、部分的に圧縮された繊維体が次に第二支持体に移送され、前記第二支持体が繊維体の圧縮された部分によって被覆される部分(単数又は複数)において穿孔を含むが繊維体の未圧縮部分によって被覆される一以上の部分内には穿孔を有さないこと、繊維体の第二圧縮は第二支持体の穿孔を有さない部分(単数又は複数)を被覆する繊維体の部分において繊維体が第二支持体に配置されたときに行われ、その後、もし必要ならば繊維体の圧縮されるべき全ての部分が圧縮されるまで同様の圧縮工程が繰り返されることを特徴とする方法。
本発明は添付の図面を参照して以下説明される:
図1は本発明の第一実施態様における圧縮装置の側面図を模式的に示す。
図2は図1の装置の平面図を示す。
図1及び2に示されている圧縮装置は第一移送車輪1、第一移送車輪1と相互作用する第一圧縮ローラ2、第二移送車輪3及び第二移送車輪3と相互作用する圧縮ローラ4を含む。移送車輪及び移送車輪と相互作用する圧縮ローラの回転方向は図1において矢印によって示されている。
Claims (5)
- 負圧によって穿孔支持体(1,3)上に適所に保持されている繊維体の圧縮方法において、圧縮されるべき各繊維体が最初に第一支持体(1)上に配置され、前記第一支持体(1)が繊維体によって被覆される領域内に穿孔を有する部分(8)及び穿孔を有さない部分(7)を含むこと、繊維体の第一圧縮が第一支持体(1)の穿孔を有さない部分(単数又は複数)(7)を被覆する繊維体の部分において行われること、部分的に圧縮された繊維体が次に第二支持体(3)に移送され、前記第二支持体(3)が繊維体の圧縮された部分によって被覆される部分(単数又は複数)(11)において穿孔を含むが繊維体の未圧縮部分によって被覆される一以上の部分(12)内には穿孔を有さないこと、繊維体の第二圧縮は第二支持体の穿孔を有さない部分(単数又は複数)(12)を被覆する繊維体の部分において繊維体が第二支持体(3)に配置されたときに行われ、その後、繊維体の圧縮されるべき全ての部分が圧縮されるまで同様の圧縮工程が繰り返されることを特徴とする方法。
- 支持体が走行する搬送トラック(1,3)からなること、及び繊維体が走行方向に延びる二つの横領域(8)において第一支持体(1)上に保持され、かつ走行方向に延びる中央領域(11)において第二支持体(3)上に保持されることを特徴とする請求項1記載の方法。
- 繊維体を圧縮する装置において、前記装置が第一搬送トラック(1)、第一圧縮装置(2)、第二搬送トラック(3)、及び第二圧縮装置(4)を備えること、前記第一搬送トラック(1)が第一搬送トラックの走行方向に延びる一以上の領域(8)において穿孔され、かつ一以上の真空箱(5)と相互作用し、かくして第一搬送トラックの穿孔された領域(単数又は複数)において第一搬送トラックの荷重支持側に負圧が形成されること、前記第一圧縮装置(2)を通して第一搬送トラック(1)が走行し、前記第一圧縮装置(2)は第一搬送トラック(1)の非穿孔領域(7)に位置される繊維体の部分において第一搬送トラック上に搬送される繊維体を圧縮するように配置されていること、前記第二搬送トラック(3)が第二搬送トラックの走行方向に延びる一以上の領域(11)において穿孔されており、前記領域が横方向において第一搬送トラック(1)の非穿孔領域(7)に対応し、一以上の真空箱(6)と相互作用し、かくして第二搬送トラックの穿孔された領域(単数又は複数)(11)において第二搬送トラックの荷重支持側に負圧が形成されること、及び前記第二圧縮装置(4)を通して第二搬送トラック(3)が走行し、前記第二圧縮装置(4)は第二搬送トラック(3)の非穿孔領域(12)に位置される繊維体の部分において第二搬送トラック上に搬送される繊維体を圧縮するように配置されていることを特徴とする装置。
- 第一及び第二圧縮装置が圧縮ローラ(2,4)からなることを特徴とする請求項3記載の装置。
- 第一及び第二搬送トラックが移送車輪からなることを特徴とする請求項4記載の装置。
