Abstract
Apparatus for bending pipes, particularly plastic or composite pipes, includes a chucking fixture for anchoring the pipes near the bending region, a bending template, the profile of which is made to fit the pipe cross section, and a bending cylinder which, in turn, has a profile that is made to fit the pipe cross section and is supported by a provided lever which, during a pivoting motion of the bending cylinder, is moved on a graduated circle about the bending template and runs concentrically to the surface of the bending template. In order to achieve easy manipulation, the apparatus is constructed as a manually operated device and parts of the apparatus are disposed on a mounting plate which is provided with a hand lever as a back-stop and which has a pivoted lever in the form of a hand lever for the bending cylinder.
