  • APPARATUS FOR PRODUCING A POLYMER PELLET
    Publication number: 20110229594
    Abstract: An apparatus for producing a polymer pellet is provided. The apparatus includes a conveying mechanism configured to convey a coated polymer, a supporting mechanism configured to support the coated polymer, a supporting plate having a deforming and cutting mechanism configured to deform and cut the coated polymer, a reciprocating mechanism configured to reciprocate the supporting plate upwardly and downwardly, and a collector configured to collect cut pellets. The reciprocating mechanism holds the supporting plate so that the deforming and cutting mechanism faces the coated polymer.

  • Method of producing non-mutually-adhesive polymer pellet, and apparatus therefor
    Patent number: 7981339
    Abstract: A method and apparatus are provided for continuously producing a polymer pellet efficiently in which, in storing, transporting or feeding to a processing apparatus, the obtained pellets containing the adhesive polymer do not easily mutually adhere, and handling thereof is excellent. The method comprises a step of deforming at temperatures of about 30 to 150° C. under pressure an adhesive polymer coated with a thermoplastic polymer, and a step of cutting the deformed portion of the coated polymer.
