Abstract: The gear for twin-screw extruders having a first output shaft which is driven by a drive shaft and a second output shaft which is driven by the first output shaft via two side shafts which are arranged on both sides. The shafts are arranged parallel and inside a joint gearbox case which is divided along a vertical junction plane into two gearbox case halves. The junction plane extends between the axes of the two output shafts.

Abstract: A safety strip for use on moving devices with the danger of pinching has a plurality of contact elements assembled into a row under an axial prestress along the safety strip. Extending in these contact elements are electrically conductive contact pins that, in the off, i.e. non-operate state maintain a circuit through the adjacent contact elements by contact and in the event that the safety strip is deformed through some external force open the circuit through the spatial distance from each other. The axial prestress and control of the individual contact elements is effected by means of an elastic tubing. However, in the present state-of-the-art, such safety strips result in a high material load in the area of the contact zones between the individual contact elements and, in addition, have only a limited maintainability.
