摘要： PURPOSE: To provide an appearance suitable for slats of a blind and assure a sufficient strength by, after laminating a fabric band-shaped body on a metal band-shaped body and rolling it cylindrically, bending a side portion of the band-shaped body in U-shape. CONSTITUTION: A fabric band-shaped body 12 is laminated on a metallic band- shaped body 11 so as to roll it in a cylindrical outer shape. Next, each of the vertically side part of the metallic band-shaped body 11 is bent so that it becomes each of U-shaped seamed parts connected to each other at a seamed part. Then, a blind rail 13 suitable for slats of a Venetian blind is formed. At the compressive and pressing steps of a production process, the thickness of the fabric band-shaped body is reduced from a specified size of three times the thickness of the metallic band-shaped body to a specified size of two times the thickness of that body.

摘要： PURPOSE:To obtain a metallic pipe having built-in filament by advancing a metallic tape having a female body and a male body at both edges in the direction of longer axis, forming to round tubular form successively by a forming device, putting filament longitudinally inside, and coupling the female body and male body. CONSTITUTION:A metallic tape having a female body 2a and a male body 2b at both edges in the direction of longer axis is sent out from a reel 14, and made into a cylindrical formed pipe having open upper part by a forming device 15. Filament 1 is sent out successively from the opening from a reel 11 and put in the formed pipe. Then, the female body 2a and male body 2b at both edges are coupled by a joining device consisting mainly of a roll 12 for coupling. Thus, a metallic pipe 3 having built-in filament 1 is formed. This is taken up on a reel 13.

摘要： (57)【要約】本発明は、縦シームを有する金属容器、特に薄鋼板容器を加工するための圧延機械であって、フラットな金属プレートから円筒状のボディが曲げ加工され、該ボディの互いに隣接する突合せ縁が互いに溶接され、次いで、ディスク状の下部底部及び場合によっては対応する上部底部が円筒状のボディ（＝中間製品）に溶接されて、閉じられた容器又は上部で開放した容器が形成される。問題点は、内側の溶接シーム縁がしばしば早期の錆発生及び充填物汚染の原因になるということにある。本発明によれば、圧延プロセスは連続圧延機械（１８）において行われ、この場合、ボディ（１２）が一方のステーション（＝積込み位置Ａ）で積込まれかつ同時に完成したボディ（１２）が他方のステーション（＝積降し位置Ｂ）で積み降ろされる。この場合、上側の内側の圧延支持部材（２６）は中央で支承される。圧延プロセス中には圧延装置は外側で支承される。つまり、連続圧延機械（１８）の特殊性は、上側の圧延支持部材のいわば“交互の遊動式”の支承形式、即ち、交互の中央及び外側でのロックもしくは固定支承形式にある。

摘要： PURPOSE: To obtain a machine for forming a Pittsburg type duct continuously from a sheet material in which high productivity can be attained by bending first through third side faces sequentially after forming a male part at the front fringe of the material and finally performing a work for jointing male and female parts continuously. CONSTITUTION: When a metal sheet fed out from an uncoiler and shaped flatly is introduced into a forming unit 18, front edge of the material is fed onto a table 20 by the distance at the male part of a Pittsburg seam and then the material is grasped. A male part 54 is formed by turning a bend beam 42 by about 90 deg. and then the material is released and fed by a specified amount before being grasped and bent similarly to form the first side face of the duct part. Similarly, the material is fed by a specified amount at a time to form second and third side faces 58, 60 sequentially. Subsequently, the material is advanced over the edge part of V-shaped dies 24, 32 and Z-shape is formed as a preliminary female part which is then combined with the male part to form a duct.

摘要： PURPOSE:To restrict the generation of deformations and burrs during a working pass, by applying a chamfering work for a seam of a pipe formed by bending a square blank sheet, by forcing a projection of a die or a punch slidable against a die block so as to penetrate into said blank sheet. CONSTITUTION:A mobile die 6 is installed freely slidably against a die block 5 in order to apply a chamfering work to the cutting end face of a square blank sheet 4 sheared along a V-groove cut into a middle thickness prepared by a punch in a hoop material. A spring 15 is provided at the bottom of the die 6 which thereby goes down only when it is pushed down with a prescribed or larger force. A penetrating projection 8 is provided in the upper part of the chamfering side edge of the die 6; hereupon, the upper face of this projection 8 is formed into an impression face 8a inclining downward directing the side edge. Hereby, if the punch 7 is put down in order to apply a chamfering work, the projection 8 of the die 6 penetrates into the blank sheet 4 that is thereby restricted from escaping in the direction opposite to the working plane 9. Under this condition, the impression face 8a pushes the part to be worked of the blank sheet 4 toward the working plane 9 of the die block 5, and the chamfering work is performed therewith.
