Cylindrical brush and method of manufacture

A method for manufacturing a cylindrical brush of a cleaning tool, the method comprising the steps of:

• a) creating a molding assembly comprising:
• i) positioning at least one of a plurality of rail plates on a foam-fitting recess of a first plate having a plurality of first plate holes, each of the plurality of rail plates including a plurality of rail holes;
• ii) positioning the at least one of the plurality of rail plates aligned with the first plate on a second plate;
• iii) placing the second plate aligned with the at least one rail plate on a seal plate;
• and
• iv) placing a top plate having a plurality of top plate holes on the first plate thereby creating the molding assembly;
• b) locking the molding assembly utilizing at least one locking member;
• c) mixing polyvinyl alcohol (PVA) into a PVA gel;
• d) injecting the PVA gel into each of the plurality of top plate holes utilizing an injection device;
• e) enabling the PVA gel to seep down through at least one of a plurality of second plate holes on the second plate to create at least one of a plurality of PVA nodules;
• f) allowing the PVA gel to overflow thereby filling an internal cavity of the at least one of the plurality of rail plates and creating the plurality of PVA nodules at the second plate;
• g) placing the molding assembly into a heating apparatus;
• h) enabling the heating apparatus to cure the plurality of PVA nodules thereby creating at least one of a plurality of PVA nodule foam bars;
• i) removing the at least one locking member from the molding assembly;
• j) removing a portion of pegs of the PVA sponge material;
• k) removing the first plate and peeling off the remaining pegs of the PVA sponge material;
• l) Removing the seal plate thereby facilitating removal of the at least one of the plurality of PVA nodule foam bars;
• m) repeating steps a)-1) until the plurality of PVA nodule foam bars being created;
• n) inserting the plurality of rail plates along an outer wall of a core member having a plurality of core holes of the cleaning tool in a unique pattern such that the plurality of core holes aligns with the plurality of rail holes;
• o) installing each of the plurality of PVA nodule foam bars at each of the plurality of rail plates;
• and
• p) enclosing a pair of openings of the core member utilizing a pair of end caps;
• whereby the unique pattern of the plurality of rail plates along the outer wall of the core member allows the plurality of PVA nodules to clean electronic components efficiently when filled with water.

• iii) placing the second plate aligned with the at least one rail plate on a seal plate, the seal plate prevents the plurality of second plate holes from exposing to open air;
• and
• iv) placing a top plate having a plurality of top plate holes on the first plate and aligning the plurality of top plate holes with the first plate holes thereby creating the molding assembly;

• g) placing the molding assembly into a heating apparatus;
• h) enabling the heating apparatus to cure the plurality of PVA nodules to convert the PVA gel in the plurality of PVA nodules into a PVA sponge material thereby creating at least one of a plurality of PVA nodule foam bars;
• i) removing the at least one locking member from the molding assembly;
• j) peeling off the PVA gel that being cured on the top plate thereby removing a portion of pegs of the PVA sponge material;
• k) removing the first plate and peeling off the remaining pegs of the PVA sponge material;
• l) Removing the seal plate thereby facilitating removal of the at least one of the plurality of PVA nodule foam bars having a row of PVA nodules by poking the PVA nodules through the second plate holes;
• m) repeating steps a)-1) until the plurality of PVA nodule foam bars being created;
• n) inserting the plurality of rail plates along an outer wall of a core member of the cleaning tool in a unique pattern;
