接合方法及び装置の改良に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention conveys at high speed a web wound around a long roll that is coated with paint or emulsion or printed, and moreover efficiently transports the web of the preceding roll. We aim to improve efficiency by ensuring that the trailing edge is stably joined to the leading edge of the web of the subsequent roll, and the joint location does not become an obstacle to coating or printing even when webs of various widths are joined together. The present invention relates to improvements in web joining methods and devices for achieving this.

けてスプライスしていた。これがスプライサ−と言われ
ているものである。Conventionally, a long web of film or paper wound into a roll is unwound and conveyed at high speed at a constant speed while applying an emulsion to the surface of the web, coating a light-shielding substance, or applying a moisture-proof sheet. In coating machines, laminating machines, and printing machines that laminate or print, the machine operation is stopped while the web is conveying the web end of the leading long roll and the web tip of the following long roll. Without much effort, I trimmed the ends of each web, brought them together, and then attached them with splicing tape and spliced them. This is called a splicer.
そしてその動作は、高速で運転中に行われるため、安定
した高精度の作動が要求され、両ウェブの貼り曲がりや
接合テープの貼りずれやはみ出しが起こらぬようウェブ
端部の切り揃えのタイミングと接合テープの貼りつけの
タイミングの合致を安定させることに留意した機構をも
たせている。Since this operation is performed at high speed during operation, stable and highly accurate operation is required, and the timing of trimming and aligning the edges of the webs must be adjusted to prevent bending of both webs or misalignment or protrusion of the joining tape. It has a mechanism that takes care to stabilize the timing of bonding tape application.
このような点に不安定さが残ると途中で継ぎ目がはがれ
切断してその前後に大量の不良品を出しジャムった前後
のウェブを取除く作業は困難をきわめ時間のかかる故障
となっていた。If instability remained at such points, the seams would peel and break midway through, resulting in a large number of defective products before and after, making it difficult and time-consuming to remove the jammed webs. .

はローラに巻きついてウェブ全体に支障を起こすことが
ある。However, in coating machines that apply emulsion onto webs of photographic film, especially medical X-ray film and photographic paper, it is often necessary to join webs of different widths together or to coat front and back sides. . In this case as well, the joining tape must be applied to the webs whose ends are butted together without any creases or twists, and in addition, both ends of the joining tape applied from both sides must be attached to the edge of each web. It must not be visible to the outside. The protruding portion may come into contact with the conveying roller and become stained with glue, or worse, it may wind around the roller and cause trouble to the entire web.
従来、接合テープは長目に切って継目を貼り、ウェブの
エツジからのはみ出しをエツジの内側に折り返していた
。しかし接合部でつき合わされる両ウェブの幅が異なる
場合は折り返しても狭幅の方のウェブに対してははみ出
したままとなり、前述の支障を解消することができない
状態である。Conventionally, splicing tape was cut into long lengths, seams were applied, and the protruding edges of the web were folded back inside the edges. However, if the widths of the two webs that meet at the joint are different, even if the web is folded back, the narrower web will continue to protrude, making it impossible to solve the above-mentioned problem.
そのためにむしろ接合テープを短くしてウェブのエツジ
からはみ出ないようにすると、両ウェブのつき合わせ部
の端部のかどがきり立つことになり搬送中にひっかかり
を生ずるような支障がある。For this reason, if the joining tape is shortened so that it does not protrude from the edge of the web, the edge of the abutting portion of both webs will become sharp, which may cause problems such as catching during conveyance.

。その場合、接合テープが短ければ短い程被害が大きく
なる。In addition, there is generally a gap between the two webs, and if such a gap is encountered during emulsion coating, the laminar flow will be disturbed during the laminar flow coating of the emulsion from the slide hopper. The resulting disturbance persists for quite a long time, resulting in streak-like uneven application. In other words, this will impede the coating of the portions near the edges. In that case, the shorter the bonding tape, the greater the damage.

標にする。The present invention solves these problems and prevents the joint edge portion from getting caught in the conveyance path during conveyance, causing conveyance problems such as jams, even when the widths of both webs are the same or different. The glue from the joining tape may come into contact with the conveyor rollers or guide rollers, staining them or causing conveyance problems.
The goal is to prevent the soot from causing any damage or staining the subsequent web coating surface, and from disturbing normal coating.

41, 131 and guide roller 142.143.144
and 132, 133, 134, and 135. As a result, the cutting waste is stably transported to the collection box 151 without being spilled on the way, and
Inside! The scraper 152 provided therein removes the film and stores it in the box 151. Further, the box 151 is suctioned by a suction pipe 152 to ensure that the cutting waste is collected into the box 151 more reliably. At the same time, the belt 136 is kept clean so that no harm will occur even if the belt 136 is conveyed near the webs X and Y.

2 is cut in an arc from the downstream side to the upstream side in the conveyance direction of the web, and the leading edge of the cutting chips that started to be cut at the beginning is cut into webs X and Y before the last one is finished cutting. The mechanism is such that the cutting chips are gripped by conveyor belts 136 and 146 that are driven in synchronization, and can maintain a stable posture during collection and conveyance of the cutting chips.
尚、ガイド板１３７は切断屑の途中でのこぼれが飛散し

ツジ部の角が、搬送中の障害になることもなくなる。With such a gentle curve, both edges of the web joint are shaped, so there is no risk of them coming into contact with mechanical parts during conveyance and causing trouble. This also eliminates the possibility of the exposed adhesive portion of the adhesive paper adhering to the web conveyance roller or conveyance belt and causing trouble to the coating machine or printing machine. Furthermore, the edges of the cut edges of the joints of both webs of different widths do not become an obstacle during conveyance.

(However, this does not apply to double-sided coated films, etc.) [Effects of the Invention] According to the present invention, even if two webs of different widths are joined, the edges can be shaped into a smooth shape, and coating or printing Stable and normal conditions such as coating are maintained, and transport problems such as snags caused by irregular edges during transport during processes including intermediate drying are also eliminated.
