Abstract
The invention relates to an apparatus () for producing a peripheral groove () in an end portion () of a metal tube (), in particular a metal tube () which is to be coated on the inside, the groove () being set up for receiving tube connectors, having a first, rotationally driven roller (), a second, freely rotating roller (), the first roller () having a roughened or structured surface () relative to the second roller (), a pressing device () for producing a relative movement between the first and second roller (), between a first and a second position, the rollers () 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 (), 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 () 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 () is pressed into the tube in the second position when the first roller () is driven.
