DEVICE FOR POSITIONING A SENSOR IN A PLANT FOR THE PRODUCTION OF BLOWN FILMS

摘要

A device for positioning a sensor (4) in a plant for the production of blown films comprises a rigid traverse (3) rotatably mounted on a pair of trolleys (2) that follow a circular track (1) and can be moved individually, the structure of the rigid traverse (3) being made up of at least three mutually sliding parts (3a, 3b, 3c) and the sensor (4) being mounted on the rigid traverse (3) at a central position and radially oriented towards the center of the circular track (1) on an intermediate part (3b) that is not secured to the trolleys (2) and always keeps the sensor (4) at a central position.
