Abstract
A plastic particle is formed of a plastic material having at least one integral protruding ring disposed on its outer surface. The ring may be continuous or intermittent around a perimeter of the plastic particle. Preferably, the particles have an outer diameter in the range of 0.007 inches to 0.040 inches.
Claims19
A plastic particle comprising a plastic material and having an integral protruding ring section disposed on the outer surface of said particle, wherein said particle has an outer diameter in the range of 0.007 inches to 0.040 inches.
A method of forming a plastic particle comprising a plastic material and having an integral protruding ring section disposed on its outer surface, the method comprising the steps of:
- providing a plastic particle having an outer diameter in the range of 0.007 to 0.040 inches comprising a plastic material which will form a protruding ring section on the outer surface of the plastic particle;
- heating the plastic particle until at least said integral protruding ring section is disposed on the outer surface of the particle.
A method of forming a plastic particle comprising a plastic material and having an integral protruding ring section disposed on its outer surface, the method comprising the steps of:
- providing a die with at least one die hole;
- extruding the plastic material through the die hole;
- severing the extrudate to create a plastic particle;
- cooling the plastic particle wherein said particle has an outer diameter in the range of 0.007 to 0.040 inches;
- heating the plastic particle to form said integral protruding ring section;
- and
- cooling the plastic particle containing said ring section.
A method of forming a plastic article from a plurality of plastic particles, the method comprising the steps of:
- providing a plurality of plastic particles having an outer diameter in the range of 0.007 to 0.040 inches further;
- forming a protruding ring section on said plastic particles;
- providing a forming surface for forming a plastic article;
- applying the plurality of plastic particles on the forming surface;
- heating the plastic particles while the plastic particles are disposed on the forming surface;
- and
- flowing the plastic particles while the plastic particles are disposed on the forming surface to form said plastic article.
