本考案は合成樹脂その他比較的気密性の材料よ
りなるチユーブ状物に印刷する装置に関するもの
で、この種の材料によるチユーブ状物に対しスム
ーズに適確な仕上りのよい印刷を行うための圧胴
を提供するものである。[Detailed description of the invention] The present invention relates to a device for printing on tube-like objects made of synthetic resin or other relatively airtight materials, and is capable of printing smoothly and accurately on tube-like objects made of this type of material. It provides an impression cylinder for printing.
従来よりインフレーシヨン法その他による合成

ラムとの間に蓄積されて印刷適性を阻害し印刷ず
れや欠字等の印刷不良を起す原因となつている。 Conventionally, in order to print characters, figures, etc. on synthetic resin tube-like objects using the inflation method or other methods, it is possible to print characters, figures, etc. on synthetic resin tube-like objects by folding the tube-like object flat and rolling it up into a long sheet of paper, which is then printed on a rotary printing machine. However, at this time, the air inside the tube is compressed and blocked by the impression cylinder and the printing cylinder, and is accumulated between the unwinding drum and the unwinding drum, which impedes printing suitability and causes printing defects such as printing misalignment and missing characters. It is becoming.
これを防止するためチユーブに脱気孔をあける
前処理を施すことが行われているが、二次加工工
程（被覆包装、或は製袋等）でこの部分を選別、
摘出しなければならず、不経済であり、また無駄
な労力を費やす欠点がある。 In order to prevent this, pre-treatment is performed to make deaeration holes in the tube, but this part is sorted out in the secondary processing process (coated packaging, bag making, etc.).
It has to be extracted, is uneconomical, and has the disadvantage of wasting effort.
さらに上記欠点を解決するための方法としてチ
ユーブ状物の少くとも一方の折目乃至その近傍を

適用できない。 Furthermore, as a method to solve the above-mentioned drawbacks, a concave groove is provided in the circumferential direction of the impression cylinder in a portion including at least one fold of the tube-shaped object or its vicinity, so that the tube-shaped object can be kept in a non-pressed state. A method is known in which printing is performed while forming an air passage on at least one side edge of the substrate. (Japanese Patent Publication No. 51-74710). However, this method is very effective when there is no printed surface on the side edge of the tube-like object, but when the side edge has a printed surface, this part is a concave groove provided in the circumferential direction of the impression cylinder. Since it is in a non-pressed state, it cannot be printed, and cannot be applied when printing on the entire surface of a tube-shaped object.
本考案は上記欠点を改良するため圧胴の胴長方
向と平行に凹溝を複数設け、空気通路としたこと
を特徴とする印刷用圧胴を提供するものである。 In order to improve the above-mentioned drawbacks, the present invention provides a printing impression cylinder characterized in that a plurality of grooves are provided in parallel to the longitudinal direction of the impression cylinder to form air passages.
以下図面により本考案を詳細に説明する。 The present invention will be explained in detail below with reference to the drawings.

通過しこの際印刷が施されるものである。 FIG. 1 is an overall schematic view of the present invention, and FIG. 2 is an overall schematic view of the impression cylinder shown in FIG. 1 in a different rotational position. A tube 5 is unwound from an unwinding drum 1 on which an original tube is wound, and is transferred to the winding side by a plurality of guide rolls 2. In the middle, the tube 5 passes through a printing position between the impression cylinder 3 and the printing cylinder 4, where printing is performed.

空気７は後方へ移動するため印刷前のチユーブは
ほとんど一枚のシート状になつてスムーズに印刷
位置に送入されて正常に印刷が行なわれる。 The impression cylinder 3 is provided with a plurality of grooves 6 parallel to the cylinder length direction. The tube 5 has an impression cylinder 3 and a printing cylinder 4.
Printing is performed by the pressure of Then, at the impression cylinder position shown in FIG. 2, the air 7 moves to the rear of the printing position. Although the amount of air that moves during the above operation is small, by providing a large number of grooves 6 in the impression cylinder 3, the air 7 moves backward, so that the tube before printing becomes almost a single sheet. The paper is smoothly fed into the printing position and printing is performed normally.
本考案における凹溝６の形状については印刷面
の欠字が発生しない微少なものを設ける必要があ
り、溝の深さを0.5〜1.0mmの範囲、好ましくは0.8

が内圧によつてチユーブを印刷胴面に押し付ける
ため欠字が発生しない。 The shape of the groove 6 in the present invention must be so small that it will not cause missing characters on the printed surface, and the depth of the groove should be in the range of 0.5 to 1.0 mm, preferably 0.8 mm.
The purpose can be achieved by setting the groove width to about 0.8 to 1.0 mm. In the groove in such a range, the air moving into the groove presses the tube against the printing cylinder surface due to internal pressure, so that no missing characters occur.
以上のように構成されているので本考案の圧胴
によれば、印刷工程中に送給される原反チユーブ
中に空気が蓄積することがなく扁平に密着状態で
折られたまま印刷位置にスムーズに供給され、ま
た欠字のない精度の高い印刷が可能となり、従来

く、長い巻長さの印刷したチユーブを得ることが
できる。 With the above-described structure, the impression cylinder of the present invention prevents air from accumulating in the tube fed during the printing process, and the tube remains flat and tightly folded until it reaches the printing position. It allows for smooth feeding, highly accurate printing without missing characters, and there is no need to provide vent holes every 30 to 50 meters as in the past, making it possible to obtain printed tubes with long roll lengths.
