PERFORMANCE AND BENEFITS TECHNICAL SOLUTIONS<br />

This device is designed to give cross direction activity to the stock in the forming zone of the Fourdrinier, which allows<br />

changing the orientation of the fi bres (contained in the paper stock).<br />

SPECIAL FEATURES<br />

The stroke can be mechanically adjusted by means of angular position of the rotating masses.<br />

The shaking device is controlled by a control cabinet. The controls are gathered on the operator screen.<br />

The use in combination with a carbon fi bre breast roll permits to reach higher shake numbers for the same force as a<br />

standard metallic breast roll, together with a reduced power consumption.<br />

In order to reach high values of stroke at high frequencies, <strong>ABK</strong> customizes each shake unit rod in terms of mechanical<br />

strength. Doing so, the range of frequency and stroke is optimized according to the customer needs.<br />

Our shake unit design integrates the lubrication unit together with its piping. This makes the unit very compact and<br />

easy to install.<br />

Recoiless Shake <strong>Unit</strong><br />

The inertial <strong>ABK</strong> shaking device consists of one basket hanging inside a main guard. This one is connected to the<br />

breast roll by means of one axis and hanging by bars.<br />

Two pair of off-centred and unbalanced loads are independently driven by two motors and angularly dephased ; the<br />

resulting force generates the back and forth movement of the breast roll. As no vertical force is created by the shaker<br />

and because only the inside basket is moving and not the main guard, no effort is transmitted to the civil works.<br />

The lubrication of the equipment is assured by a greasing plate consisting of pump, fi lter, exchanger, sensors permitting<br />

the continuous lubrication of the bearings and the gears.<br />

The unbalanced loads are driven by means of two servo-motors, the frequency depends on the number of revolution<br />

and the amplitude is a function of the phase-shift angle between the two pairs of loads. The 2 bottom and top loads<br />

are synchronized by gears.<br />
