Abstract: The invention relates to a matrix for a tire mold for vulcanizing tire blanks, the matrix forming a negative mold of a profiled tread of a tire, the matrix having a mold shell and at least one fin plate disposed thereon, the mold shell forming a mold inside and the fin plate forming a web of the negative mold, a slit being formed in the mold shell, the fin plate being inserted into the slit and attached to the mold shell. The slit penetrates a mold wall of the mold shell and extends from the mold inside to a mold back side of the mold shell, the fin plate being bonded to the mold shell from the mold back side.

Abstract: The invention relates to a lance for removing deposits adhering to the tube sheet of a steam generator, comprising a flexible strip which is introducing into intermediate tube areas of the steam generator, which has a cleaning head at the free end of the strip, and which comprises at least one water hose that is used to supply a flow of water to the cleaning head. In a use situation, the cleaning head comprises a working face which faces the tube sheet or deposits present thereon, an outlet opening which is fluidically connected to the water hose and opens into the working face, and a mechanical tool which acts on the deposits and removes material.

Abstract: A drum for the manufacture of a tire, in particular for winding or clamping a tire body, includes a circular cylindrical drum unit formed from circular-arc-shaped drum segments. The drum segments are movable in a radial direction, transversely to a rotation axis of the drum, such that an external diameter of the drum unit is changeable. The drum further includes an actuation device and a deflection device. The actuation device moves the drum segments. The deflection device has obliquely arranged telescopic guides that transfer an axial movement of the actuation device into a radial movement of the drum segments.
