摘要： An extruder, such as a double-screw extruder includes a double cylinder and a double-lead screw arranged therein with a drive train for the screw. The drive train has a coupling with the screw. The extruder includes a sensor for recording a moment load having torque and/or bending moment and for generating electronic data from the recorded moment load. A controller is provided in operative connection to a drive for the drive train and the sensor is in data connection with the controller. The controller is adapted to evaluate the data on the recorded moment load and to trigger a protective action if a threshold value set in the controller is exceeded. The evaluation includes a bending moment calculation. A plastic molding plant produces a film with the extruder along with a nozzle unit and a cooling and wind-up unit or a compounding plant. A method for operating such a plant for manufacturing a film includes the extruder.

摘要： The invention relates to a double-screw screw-spindle pump (10) of single flow design having a pump housing (11) which has a pump section (12), a bearing section (16) and a gear mechanism section (17) with a gear mechanism space (32), the bearing section (16) and the pump section (12) being configured separately from one another, having a conveyor housing part (13) as a constituent part of the pump section (12), in which two conveying screws (24, 25) which have flanks (42, 43) and are arranged on shafts (22, 23) are provided, the shafts (22, 23) being mounted in the bearing section (26) (external bearing) and extending into the gear mechanism section (17). It is an object of the invention to improve the abovementioned pump such that highly viscous, non-flowing media can be conveyed. The object is achieved by virtue of the fact that the pump housing (11) has an extruder section (14) which is connected to the pump section (12), that an extruder housing part (15) is provided, through which the shafts (22, 23) extend, and that extruder screws (27, 28) with flanks (50, 51) are provided on the shafts (22, 23).

摘要： An improved extrusion assembly is disclosed which better adapts to thermal changes resultant from the transport of high-temperature extrudate. An extrusion screw present in the assembly includes a hollow portion. A biasing member is disposed in the hollow portion. When the assembly is transporting high-temperature extrudate, the biasing member's included Belleville washer component compensates for the thermal expansion and contraction of the extrusion screw.

The rotor (6) is non-rotatably connectable to the drive shaft (1). The drive shaft (1) is connected non-rotatably to the roller or screw at a connection end (1a). The stator (5) is non-rotatably retained by a stationary component of the drive. The rotor (6) is mounted axially rotatably on a motor housing (7) with a motor bearing (8) facing the connection end (1a) of the drive shaft and with a motor bearing (9) facing away from the connection end (1a) of the drive shaft. The drive shaft (1) is guided coaxially to the rotor (6) through the drive motor (18) and beyond the drive motor (18), where the drive shaft has a free end (1b). The drive shaft is configured as a hollow shaft having an axial tempering medium channel (1c), which is coupled at the free end (1b) of the drive shaft to a tempering medium connection (12, 13).
