Abstract: An air nozzle of an air outlet in an interior of a motor vehicle. An operating element is adjustable around an axis of rotation. A kinematics adjustment system has a deflection unit where, via an adjustment of the operating element, a shut-off flap inside the air outlet is displaceable around a flap axis by the kinematics adjustment system. The operating element is disposed on an end of an actuator rod where the actuator rod is displaceable in a direction of extension from an actuating position into a locking position. The axis of rotation of the operating element runs transversely to the flap axis, a rotational movement of the actuator rod is deflectable by the deflection unit into a rotational movement of the shut-off flap, and, by displacing the actuator rod into the locking position, the deflection unit is lockable by applying a spring force to the deflection unit.

Abstract: A blowing head, a method for producing a blown film, and a blown film installation include the use of plate spiral distributors in blown film installations for distributing melt steams arriving from extruders and for combining the melt streams to form an annular gap stream in several layers in an annular gap leading to a tubular die. The melt streams in a plate spiral distributor are initially bundled and then forwarded in a bundled manner to a common co-extrusion flow. The distributer has a plurality of spirals in superimposed layers, and the spirals of two layers have a junction for pre-combining the melt streams of two layers, and in that starting from the junction, a common guide leading to the annular gap is provided for combining there the pre-combined melt streams with the annular gap stream.

Abstract: A machine tool has, on a machine bed, two stands which can be moved in the horizontal x- and z-direction, on which y-slides carrying tool spindles can be vertically moved. Arranged on one of the stands directly above a bridge projecting over its upper side is at least one tool magazine, with which a tool changer is associated for each stand. The drives for the y-slides are attached below the upper side of the stands to the stands.

Abstract: A flow-rearrangement device between the annular extrusion gap of an extrusion head and the feed for the thermoplastified synthetic resin has two disks with registering grooves forming rearrangement ducts communicating axial inlet bores with axial outlet bores to effect a flow rearrangement of the thermoplastified synthetic resin which produces microtexturing of the finished product. The extrusion head may be a film or foil blowing head.
