<p>The applicator for clay onto a floor of a boat canal has an applicator head (11) with a vertical fed duct (15) and a transfer duct (12) to a horizontal discharge outlet (13). The vertical feed duct has a positioning support (20) which is connected to it by a lower horizontal pivot axis (21). It also has an upper adjuster formed by a cylinder and piston (23) with the piston rod (22) pivoted to the feed duct. The cylinder and piston assembly allows adjustment to compensate for the recoil action of the outlet flow.</p> |
