Abstract: The invention relates to an apparatus (1) for producing a peripheral groove (101) in an end portion (103) of a metal tube (100), in particular a metal tube (100) which is to be coated on the inside, the groove (101) being set up for receiving tube connectors, having a first, rotationally driven roller (3), a second, freely rotating roller (5), the first roller (3) having a roughened or structured surface (6) relative to the second roller (5), a pressing device (15) for producing a relative movement between the first and second roller (3, 5), between a first and a second position, the rollers (3, 5) assuming a first spacing from one another in the first position, which first spacing permits an introduction of a wall of the tube between the rollers (3, 5), and assuming a smaller, second spacing from one another in the second position, which second spacing is smaller than a material thickness (M) of the wall of the tube.
It is proposed according to the invention that the first, driven roller (3) is set up to grip the tube from the outside in the second position and to rotate it, with the result that a peripheral groove (101) is pressed into the tube in the second position when the first roller (3) is driven.

Abstract: A pipe grooving device having a plurality of geared cams uses synchronizing gears, each of which meshes with two of the geared cams, to synchronize the rotation of the cams which engage the pipe element to form the groove. The position of the groove relative to the end of the pipe is controlled by a stop body which incorporates a plate mounted ring which engages and disengages with a pipe stop surface on one or more of the cams to limit or permit cam rotation. The pipe stop body is positioned within a cup which receives the pipe element. The cup limits pipe end flare and limits the tendency of the pipe to go out of round during the grooving process. The device mounts on a powered chuck which turns the pipe element.

Abstract: In the method for producing a set of cooperating embossing rollers, a modelling device is used for parameterizing the embossing rollers, the device comprising a test bench having a pair of rollers which are put under hydraulic pressure that can be measured and set, in order to determine from the measurement data the parameters for producing the embossing rollers. The use of a modelling device for obtaining the parameters for producing a set of embossing rollers makes it possible to use a very large variety of embossing patterns and foils with diverse properties as a basis and, by conducting tests on this very test bench, be able to efficiently narrow down and predetermine the properties of a final embossing device, preferably operated without hydraulics.

Abstract: A tube and method for sizing the effective inside diameter of the tube to a smaller effective inside diameter is provided. The method uses rollers that apply focused pressure to the tube to create a crease that reduces the effective inside diameter without substantially changing the outside envelope of the tube. The crease may be either a radius or squared. Reducing the effective inside diameter of the tube creates radiused surfaces for a self-tapping screw to cut threads.

Abstract: In a method for forming a pipe element, a spin forming tool is revolved in an orbit of increasing diameter within the pipe element. The pipe element is captured within a die. The method forms a circumferential shoulder at one end. The shoulder has an outer diameter greater than the outer diameter of the pipe element. A groove is formed adjacent to the shoulder. The groove has a floor surface with an outer diameter less than the outer diameter of the pipe element. A bead is formed contiguous with the groove. The bead has an apex with an outer diameter greater than the outer diameter of the pipe element.

Abstract: A plate workpiece processing tool includes a first tool portion and a second tool portion. The first and second tool portions are arranged along an application axis in spaced relation to each other such that a plate workpiece can be disposed therebetween. The tool also includes two or more processing devices that are carried by the first tool portion, and one or more counter-devices that are carried by the second tool portion. The processing devices are rotatable, relative to the first tool portion, about a first rotational axis that extends perpendicular to the application axis and are arranged to follow each other along an axis extending perpendicularly to the application axis. The processing devices and the one or more counter-devices are selectively alignable to form a plurality of alternative device pairings for processing plate workpieces therebetween.
