Abstract: An apparatus for parting pipe has two shearing members bearing against each other and mutually movable along a cutting plane and with holes for the pipe which form exterior shearing edges. The pipe bore is supported by a mandrel divided into two sections mutually displaceable and forming interior shearing edges. The moving shearing member is driven by a crank mechanism, including a single crankshaft, at a mounting arrangement spaced from a bearing arrangement via which the fixed and the movable shearing members are mounted and guided and in which an elongate hole has its longitudinal axis directed towards the crankshaft and a bolt adapted to said hole.

Abstract: An apparatus for bending a pipe about a fixed forming member serving as abutment has members gripping the pipe externally as well as two mandrels intended to come inside the pipe. Each mandrel has an end piece movably carried by one end, the end pieces being against each other inside the pipe at the beginning of bending. During the initial bending phase, each end piece is urged outwards from the bending center to expand the pipe to such an extent that after terminating bending, the pipe is given a circular cross section subsequent to a certain amount of return spring of the pipe wall.
