とする。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a coated metal plate in which the surface of a strip-shaped metal substrate is coated with resin and cut at desired locations, and an object of the present invention is to easily achieve rust prevention on the cut end surface. .
かかる被覆金属板製造方法は、生産性の面では
高いが金属基板の切断端面は樹脂で被覆されず露
出するので金属錆が発生し外観を損う欠点があつ
た。 Although this method of manufacturing a coated metal plate is high in terms of productivity, it has the disadvantage that the cut end surface of the metal substrate is not covered with resin and is exposed, resulting in metal rust, which impairs the appearance.
本発明はかかる欠点に鑑みて為されたものであ

ものである。 FIG. 1 shows a metal substrate 1 made of a band-shaped material (hoop material) made of, for example, a steel plate or an iron plate, in which narrow bridge pieces 2 are arranged at desired pitches in the direction in which the band-shaped material extends.
It has cutting bands 2 arranged alternately with separation parts 2b, 2a, . (Only one location is shown in the figure.) Figure 2 shows the surface (of course, the end surface of the plate thickness) of the strip-shaped metal substrate 1 while it is continuously running in the X direction shown in the figure.
This shows a cross section of the cut band 2 of a coated metal plate 4 formed by continuously coating a resin coating 3 such as vinyl chloride resin, polyester resin, or polypropylene resin by, for example, extrusion molding or continuous dabbing processing. .
第３図は上記第１図及び第２図に示す工程を経

工程を示している。 FIG. 3a shows the bridging piece parts 2a, 2a... (of course, the resin coating 3 coated on the front and back sides thereof) and the separation part 2.
The first step is to separate the resin filled between b by shearing.
Fig. 3b shows the second step of peeling off the resin coating 3 covering the front and back surfaces of the crosslinking piece 2a from the crosslinking piece 2a using edged blades 5, 5; Figure 3c shows the third step of cutting the exposed tip of the bridge piece 2a short, and Figure 3d shows the resin coating 3 from which the exposed part of the shortened bridge piece 2a has been peeled off, and is heated to the cut end surface. 4th to fully cover
It shows the process.
第４図は本発明の異なる実施例に係る金属基板

れ前記実施例同様切断端面を樹脂で被覆される
が、切断端面が被覆金属基板の端面より突出しな
い点で優れた実施例である。 FIG. 4 shows a metal substrate 1 according to a different embodiment of the present invention, in which the width of the cutout portion 2b is the same as that of the bridging piece portion 2.
The width is widened near a (i.e., the bridge piece 2a
A cutting relief 6 is formed at the base of the cutter. The bridging piece 2a is cut near its both ends (as shown in the figures BB and B'B'), and the cut end surfaces are coated with resin as in the previous embodiment, but the cut end surfaces do not protrude from the end surfaces of the coated metal substrate. This is an excellent example in this respect.
第５図は本発明のさらに異なる実施例として、
裏面は防錆メツキ層７が露出し表面は樹脂被覆３
で覆われている金属基板１を巾全部に渡り切断
後、巾全部の樹脂被覆３をはく離する場合を示し
ており、前記実施例と同一思想のものであること
は容易に理解されよう。 FIG. 5 shows a further different embodiment of the present invention.
The rust-proof plating layer 7 is exposed on the back side, and the resin coating 3 is on the front side.
This figure shows the case where the resin coating 3 over the entire width is peeled off after the metal substrate 1 covered with the metal substrate 1 is cut across its entire width, and it will be easily understood that the idea is the same as that of the previous embodiment.
本発明の被覆金属板製造方法は、上述の如く、
架橋片部において切断し、この架橋片部の端面の
露出部のみを被覆するものであるので、被覆する

る。 As mentioned above, the coated metal plate manufacturing method of the present invention includes:
Since the bridge piece is cut and only the exposed end face of this bridge piece is covered, the area to be covered is small, and the part to be coated protrudes from the cut-off part, making the coating process easy. It can be done. That is, it is easy to peel off the resin coating near the cut end surface, cut out the exposed metal substrate, and heat the peeled resin coating again to cover the exposed portion of the metal substrate end surface.
このようにして帯状の金属基板を基礎とする高
生産性を維持しつつ切断端面の金属露出部に発生
する錆の防止が図られたのである。 In this way, it was possible to prevent rust from occurring on the exposed metal portion of the cut end face while maintaining high productivity based on the band-shaped metal substrate.
