【発明の詳細な説明】 印刷装置のシリンダに 張り付けるためのブランケット 〔技術分野〕 本発明は、基台と弾性層とを具備する、印刷装置のシリンダに張り付けるための ブランケットに関する。[Detailed description of the invention] in the cylinder of the printing device blanket for pasting 〔Technical field〕 The present invention provides a method for pasting onto a cylinder of a printing device, comprising a base and an elastic layer. Regarding blankets.
印刷機は通常、さまざまな機能を果たす多数のシリンダを含む。 Printing presses typically include a number of cylinders that perform various functions.
特に多くのシリンダが、紙と直接接触して作用するよう配置され、紙にインクを 移す（圧胴）か、あるいはいつくかの他の機能、典型的には紙の移送あるいは供 給機能（移送シリンダ）および圧胴からの圧力に反作用する（圧力シリンダ）の ような機能を果たすように配置される。In particular, many cylinders are arranged to work in direct contact with the paper, applying ink to the paper. (impression cylinder) or some other function, typically paper transport or serving. feeding function (transfer cylinder) and reacting to the pressure from the impression cylinder (pressure cylinder). arranged to perform such functions.
前記シリンダが異なる機能を果たすためであっても、これらは、基台と弾性層と を具備する同じブランケットの形式が張り付けられる。圧胴の要求に適するよう 特に開発されてきたこのブランケットは、圧力および移送シリンダに同様に頻繁 に用いられ、紙に作用するすべてのシリンダ対に対し同様な機械特性および動特 性（特に変形可能性および周面速度）を提供するようにかつしたがって紙の取り 扱い性および印刷の正確さの最も高い可能性を保証するようにする。Even if the cylinders serve different functions, they are different from the base and the elastic layer. The same type of blanket is affixed. To suit the impression cylinder requirements This blanket, which has been specially developed, is frequently used in pressure and transfer cylinders alike. similar mechanical and dynamic properties for all cylinder pairs that act on paper. (particularly deformability and circumferential velocity) and therefore the handling of the paper. To ensure the highest possibility of handling and printing accuracy.
この選択は、しかしながら、圧力および移送ロールを清掃するのに必要な頻繁な 停止のため装置の生産性を損ない、圧力および移送ロールは、刷りたての紙から 多量のインクと紙の繊維粒子とを拾い上げる。This choice, however, reduces the pressure and frequent pressure required to clean the transfer rolls. Due to stoppages that impair the productivity of the equipment, the pressure and transfer rolls are It picks up a lot of ink and paper fiber particles.
本発明の基礎となる問題は、圧力および移送シリンダに用いたとき印刷の正確さ を損なわずに、簡単には汚れずまたどんな場合においても迅速にきれいに洗える 張り付けのブランケットを提供することである。 The problem underlying the invention is the accuracy of printing when used with pressure and transfer cylinders. Does not stain easily and can be quickly cleaned in any case without damaging the surface. The purpose is to provide a blanket that can be pasted.
この問題は、本発明による印刷装置のシリンダに張り付けるためのブランケット によって解決され、前記ブランケットは基台と弾性層とを具備し、また弾性層側 に外側フィルムをさらに具備し前記フィルムが印刷インクに対し低い親和力を有 することを特徴とする。This problem can be solved by using a blanket for sticking to the cylinder of the printing device according to the invention. The blanket includes a base and an elastic layer, and the elastic layer side is further comprising an outer film, said film having a low affinity for printing ink. It is characterized by
フィルムは、基台と弾性層とに依存するブランケットの弾性特性には影響を及ぼ さないが、インク粒子および紙の繊維がブランケットに付着する可能性を急激に 減少させる。The film does not affect the elastic properties of the blanket, which are dependent on the base and the elastic layer. However, it rapidly increases the chance that ink particles and paper fibers will stick to the blanket. reduce
前記フィルムは、適当な重合体材料から形成され、好ましくは、塩化ポリビニル （ＰＶＣ）、ポリエステル、ポリエチレン、フン化ポリビニル（ＰＶＦ）および ポリテトラフン化エチレン（ＰＴＦＥ）から選ばれる。ＰＶＦが優れた結果を生 じさせることが明らかとなっている。The film is formed from a suitable polymeric material, preferably polyvinyl chloride. (PVC), polyester, polyethylene, polyvinyl fluoride (PVF) and Selected from polytetrafluorinated ethylene (PTFE). PVF produces superior results It is clear that
有利には、フィルムは、弾性層を硬化させる前に、低温圧延方法によって弾性層 に適用される。このようにして、基礎となる弾性層上のフィルムの完全な接着が 達成される。Advantageously, the film is coated with the elastic layer by a cold rolling method before curing the elastic layer. Applies to. In this way, complete adhesion of the film on the underlying elastic layer is ensured. achieved.
選択的には、フィルムは、弾性層／基台の組立体から構造上依存しなくてよく、 またシリンダの準備７組み立ての段階の間、それに単に組み合わされてもよい。Optionally, the film may be structurally independent from the elastic layer/base assembly; It may also be simply assembled thereto during the preparatory 7 assembly stage of the cylinder.
本発明によるブランケットのさらなる特徴および利点が、添付圃面を参照したそ の好ましい実施態様の以下の詳細な記載によって明らかになろう。Further features and advantages of the blanket according to the invention can be found in its description with reference to the attached field. will become clear from the following detailed description of preferred embodiments of.
図面において、 図１および図２は、本発明のブランケットが張り付けられたロールを使用する２ つの印刷装置を略示する部分斜視図であり、図３は、本発明のブランケットの断 面図である。 In the drawing, Figures 1 and 2 show two cases in which a roll to which the blanket of the present invention is attached is used. FIG. 3 is a partial perspective view schematically showing one printing device; FIG. It is a front view.
〔発明を達成する最良の態様］ 図１に略示されたのは、印刷装置Ｓ、特に、紙Ｃのｍ個Ａに４色刷りするための ユニットＳ１と、紙Ｃの他側Ｂに単色刷りするためのユニットＳ２とを具備する ロトオフセント印刷装置の詳細図である。各ユニットＳＬ、Ｓ２は、本発明によ るブランケット２が張り付けられた圧胴Ｒと圧力シリンダＰとを具備する。[Best mode of achieving the invention] What is schematically illustrated in FIG. It includes a unit S1 and a unit S2 for monochrome printing on the other side B of the paper C. 1 is a detailed view of a roto-off cent printing device; FIG. Each unit SL, S2 is The pressure cylinder P includes an impression cylinder R and a pressure cylinder P to which a blanket 2 is attached.
図２は、代わりに、異なる印刷装置、特に、祇Ｃ′の２つの側Ａ′およびＢ′に 単色刷りするためのユニットＳ′とその側Ａ′に４色刷りするためのユニットＳ ２’とを具備するフレキソ印刷装置の詳細図を示す、各ユニットＳＬ’、Ｓ２’ は、本発明によるブランケット２が張り付けられた圧胴Ｒ′と圧力シリンダＰ′ とを具備する。FIG. 2 alternatively shows that different printing devices, in particular two sides A' and B' of C' Unit S' for monochrome printing and unit S for four-color printing on its side A' Each unit SL', S2' shows a detailed view of a flexo printing apparatus comprising: are an impression cylinder R' and a pressure cylinder P' to which a blanket 2 according to the invention is attached. and.
ブランケット２は基台３と弾性層４とを具備し、基台３は弾性材料の層６が間に 順番に挟まれた複数の襞５から成る０層６の１つは、閉じたあるいは開いたセル を有する細孔構造から成るいわゆる圧縮性層でよい。The blanket 2 comprises a base 3 and an elastic layer 4, the base 3 having a layer 6 of elastic material in between. One of the layers 6 consisting of a plurality of folds 5 sandwiched in sequence is a closed or open cell. It may be a so-called compressible layer consisting of a pore structure having .
ブランケット２は、弾性層４上に適用されかつフッ化ポリビニル（ＰＶＦ）から 形成される外側フィルム１０をさらに具備する。A blanket 2 is applied on the elastic layer 4 and is made of polyvinyl fluoride (PVF). It further includes an outer film 10 formed.
ブランケット２を製造するために、初期の段階において、基台３とその上の弾性 体との従来の方法がなされる。In order to manufacture the blanket 2, in the initial stage, the base 3 and the elastic Traditional methods with the body are done.
その方法は、弾性材料で襞を被覆しかつ低温圧延方法でさらなる襞を互いに連結 させる、後に続く段階を含む。The method involves covering the folds with an elastic material and connecting further folds to each other by a cold rolling method. including the steps that follow.
層４を有する基台３を硬化させ弾性層４の安定化をする前に、フィルム１０はそ の上で低温圧延される。この後、未処理のブランケット２が硬化され、したがっ て弾性層４の安定化とその上でのフィルム１０の固定とが同時に達成される。Before curing the base 3 with the layer 4 and stabilizing the elastic layer 4, the film 10 is Rolled at low temperature. After this, the untreated blanket 2 is cured and thus Thus, stabilization of the elastic layer 4 and fixation of the film 10 thereon are simultaneously achieved.
したがって得られたブランケット２は、印刷インクに対し非常に低い親和力であ りかつすぐにきれいに洗うことができる外側表面を有する。さらに、フィルム１ ０は、表面摩耗の優れた抵抗と、また印刷装置に通常使用される溶剤の作用に対 する化学的抵抗とを提供する。The resulting blanket 2 therefore has a very low affinity for printing inks. It has an outer surface that is easy to clean and can be easily cleaned. Furthermore, film 1 0 provides excellent resistance to surface abrasion and also to the action of solvents commonly used in printing equipment. chemical resistance.
