Abstract
A method for forming a one-piece integral multi-durometer scraper blade for a conveyor belt cleaner. The scraper blade includes a body extending longitudinally between a first end and a second end and extending transversely between a base and a tip. The body includes a first body portion comprising a first elastomeric material having a first durometer of hardness, and a second body portion comprising a second elastomeric material having a second durometer of hardness.
Claims16
A method of forming a scraper blade for a conveyor belt cleaner, said method comprising the steps of:
- pouring a molten first material into a mold to form a first body portion of the scraper blade having a first durometer of hardness;
- pouring a molten second material into the mold to form a second body portion of the scraper blade having a second durometer of hardness;
- whereby said first body portion and said second body portion are molded as portions of a single unitary member in a substantially continuous molding process.
A method of forming a scraper blade for a conveyor belt cleaner, said method comprising the steps of:
- pouring a molten first material into a mold to form a first body portion of the scraper blade having a first durometer of hardness;
- pouring a molten blend of said first material and a second material into the mold to form a transition portion of the scraper blade;
- and
- pouring molten second material into the mold to form a second body portion of the scraper blade having a second durometer of hardness;
- whereby said first body portion, said transition portion, and said second body portion are formed as portions of a single unitary member.
A method of forming a scraper blade for a conveyor belt cleaner, said method comprising the steps of:
- pouring a molten first material into a mold to form a first body portion of the scraper blade having a first durometer of hardness;
- creating a varied composition material by changing the composition of the first material to a second material;
- pouring the varied composition material into the mold as the composition of the first material is changed to the composition of the second material, the varied composition material forming a transition portion of the scraper blade;
- pouring molten second material into the mold to form a second body portion of the scraper blade having a second durometer of hardness;
- whereby said first body portion, said transition portion, and said second body portion are formed as portions of a single unitary member.
A method of forming one or more scraper blades for a conveyor belt cleaner, said method comprising the steps of:
- pouring a molten first material into a first mold to form a first body portion of a first scraper blade, the first body portion having a first durometer of hardness;
- waiting a selected period of time after the molten first material is poured into the first mold;
- pouring a molten second material into the first mold after waiting the selected period of time after the molten first material is poured into the first mold to form a second body portion of the first scraper blade, the second body portion having a second durometer of hardness;
- whereby said first body portion and said second body portion are formed as portions of a single unitary member.
