    (54) Improvements in and relating to paper making machines


    (57) A paper making machine has a forming section (1 ....13), a press section (14 .... 23) and a dryer section (24 .... 30) each of which includes a multiple jet shower head assembly (32, 33, 34, 35) for conditioning the fabric, felt or screen of the section. Associated with each shower head assembly is a sensor (34) for sensing the condition of the fabric, felt or screen. The sensor (34) is linked to a computer (35) which controls the rate of traverse of the shower head assembly across the width of the fabric, felt or screen and the number of the jets in the head to be brought into use when the sensor indicates that conditioning is required to restore the condition of the fabric, felt or screen. Showering continues under the control of the computer in accordance with the sensed condition to maintain the fabric, felt or screen in an optimum condition
