A device for cleaning rollers in paper producing machines such as those used to calendar paper in the process of manufacturing paper from pulp. The device cleans rollers in paper producing machines with a high pressure hydrospray, while the rollers remain in the machine, thus, eliminating the need to remove the rollers from the machine in order to clean them.

A roller cleaning machine for cleaning paper producing machine rollers, while such rollers are in place within the paper producing machine, including: a mobile lower base; an upper base, supported by said lower base, and pivotable with respect to said lower base; an extendable and retractable boom, attached to, and extendable outward from and retractable to said upper base; a hydronozzle positioned near a distal end of said boom for providing a high-pressure spray directed away from said boom in the direction of said machine rollers, and at substantially a right angle to the axis of said boom; said extendable and retractable boom further comprising a first stage, a second stage, a third stage and a fourth stage, each said stage sequentially extending outward in a telescoping fashion from said upper base, thereby allowing said boom to extend outward distally from said upper base, each said first stage, second stage, third and fourth stage of said boom being rigid thereby providing rigid support to said extendable and retractable boom thereby providing resistance to said boom to vibration, shaking, other stresses and further providing support for said boom against the net sideward thrust generated by the operation of said hydronozzle near said distal end of said boom; lower guides and upper guides along said extendable and retractable boom, said lower guides and upper guides further providing support to said boom against vibration, shaking, other stresses and against the net sideward thrust generated by the operation of said hydronozzle near said distal end of said boom, and said lower guides and upper guides further providing guidance for said telescoping of said boom stages; and an adjustable boom support for supporting and stabilizing said extendable and retractable boom against vibration, shaking, other stresses and against the net sideward thrust generated by the operation of said hydronozzle near said distal end of said boom said boom support being connected to said boom and adjustably extending downward toward a ground surface for adjustably connecting said boom with the ground surface, said boom support further comprising a hydraulic cylinder and dolly wheels, said hydraulic cylinder providing a means for adjusting said boom support and said dolly wheels providing a means of connecting said boom support to the ground surface for stabilizing said boom against side forces from the operation of said hydronozzle.
