Abstract:
A linear drive for a stretch and/or blow moulding machine has a force sensor for detecting actual force absorption of the linear drive during operation, a storage device in which data for a desired force absorption during operation are stored, and a comparison device for comparing actual force absorption with desired force absorption and a signal emitter for outputting a signal if a previously defined deviation between desired force absorption and actual force absorption is exceeded. Also provided is a method for determining a friction coefficient of a linear drive for a stretching and/or blow moulding machine, by determining a desired force absorption of the linear drive during operation, detecting using a force sensor, actual force absorption of the linear drive during operation, comparing actual force absorption with desired force absorption, and outputting a signal if a previously defined deviation between desired force absorption and actual force absorption is exceeded.
