An roller-flanging device for flanging at least an end region of a cylindrical body includes a receptacle having a longitudinal axis common with the cylindrical body being flanged. Flange rollers are rotatably seated in the receptacle about the common longitudinal axis, and roll along a surface of the cylindrical body. The flange rollers each have a part with a cylindrical surface and a flange collar for forming a flange contour on the cylindrical body. At least one limiting body is disposed between contiguous ones of the flange rollers, and extends inwardly toward the common longitudinal axis beyond the circumscribed cylindrical surface of the cylindrical parts of the flange rollers at least when forming the flange. The at least one limiting body prevents burrs or material from the cylindrical body from reaching or extending beyond the cylindrical surface of the flange rollers, and assures a uniform flange diameter.

A method for producing a superconducting layer of YBa.sub.2 CU.sub.3 O.sub.7 on a sapphire substrate utilizes the steps of epitaxially growing an intermediate layer that at least contains a yttrium-stabilized zirconium oxide layer directly on the substrate, and then epitaxially growing a superconducting layer on the intermediate layer. In one embodiment, the step of growing the intermediate layer grows two sub-layers, with the first sub-layer being a yttrium-stabilized zirconium oxide layer and a second sub-layer being a yttrium oxide layer applied onto the first sub-layer.

A method and apparatus for producing can bodies, wherein blanks are laterally centered after removal from a magazine, are engaged in the center of their rear edge and are transported into a shaping station in which initially the center section of the blank is bent into its final shape. While doing this, a central force and friction lock is produced between a transporting means and the deformed blank to realize reliable guidance of the already partially bent blank. To further transport the blank, it is contacted at its rear edge in the already completely bent region by two lateral transporting devices and is advanced to a seam forming station, while the opposite longitudinal edges of the blank are brought to an adjoining relationship.

A conveying apparatus feeds can body blanks to a welding unit with the longitudinal edges of the can body blanks even, without being offset in the longitudinal direction. The apparatus includes a centrally disposed revolving device (5; 5'; 5") which serves as a transport unit for the can body blanks (1). Rockers (18) are connected by means of swivel axes (5b) to serve as pusher dogs. Each rocker (18) has two feed pins (18c, 18d) at its front end facing the direction of transport. In the pushing position, the feed pins simultaneously contact the rear edge of a can body blank (1) on either side of the longitudinal edges. Each of the rocker arms is provided with a control arm which extends past the swiveling axis and which has a control surface.
摘要:
A conveyor apparatus for sequentially advancing articles in a conveying direction comprises two parallel-spaced flexible pulling elements, each trained about an upstream and a downstream end wheel. A plurality of parallel-spaced article advancing bars, each oriented perpendicularly to the conveying direction, are supported by the two pulling elements and extend continuously therebetween. A stationary article supporting surface extends from between the first end wheels parallel to the conveying direction for supporting the articles as they are pushed in the conveying direction by respective article advancing bars. The article supporting surface has a starting location adjacent the upstream end wheels for sequentially receiving the articles to be engaged by an article advancing bar. The starting location is positioned relative to the upstream end wheels such that the article dwelling in the starting location is abutted by the article advancing bar at a moment when an imaginary plane passing through the article advancing bar and containing the rotary axes of the upstream end wheels defines, with the conveying direction, an angle of 45.degree. at the most, whereby a velocity component of the circumferential velocity in the conveying direction is at the most 71% of the circumferential velocity at the moment of contact between the article advancing bar and the article dwelling in the starting location.
