摘要

The mandrel (1) for producing manifold tubes from elastomer material with/without reinforcing layer, exhibits movable sleeves (7, 14), which have stops arranged on the inside and which exhibit aeration bores (21) leading in the axial abutting face of the stops. The sleeves are solvably secured against the relative movement to the mandrel. The fastening of the sleeves at an end of the mandrel shows an interlocking nose adjoining at a stop of the mandrel and intervening in a circular groove (18) of the mandrel. The mandrel (1) for producing manifold tubes from elastomer material with/without reinforcing layer, exhibits movable sleeves (7, 14), which have stops arranged on the inside and which exhibit aeration bores (21) leading in the axial abutting face of the stops. The sleeves are solvably secured against the relative movement to the mandrel. The fastening of the sleeves at an end of the mandrel shows an interlocking nose adjoining at a stop of the mandrel and intervening in a circular groove (18) of the mandrel. The bores starting from the axial abutting face of the stops runs off in a predetermined length in axial direction and after this predetermined length runs off in an angle of 45-90[deg] to the longitudinal axis of the sleeve.
