DEVICE FOR DETECTING THE STRESS DISTRIBUTION OF METAL STRIPS STRESSED BY TENSION OF THE STRIP

摘要

The invention relates to a device for detecting stress distribution of metal bands loaded by band tension, comprising a measuring roller (A,B), at least one locating element (2) formed in the body (1) of the measuring roller (A,B), a measuring sensor (6) arranged in said locating element (2), a force transmitting element (5) inserted into said locating element (2), said force transmitting element having a load shoulder (5b) acting upon the measuring sensor (6). The cross-sectional surface of said load shoulder is smaller than the cross-sectional surface of the locating element (2). The device also comprises a cover (7) resting in the hole of the locating element (2). The surface of said cover pointing outward is arranged in a substantially surface-flushed manner relative to the peripheral surface of the body (1) of the measuring roller (A,B) and is connected to the force transmitting element by means of pressure connection. The device according to the invention makes it possible to detect the stress taking place in a metal band in a reliably manner and with a minimized risk of disturbing influences.
