Abrégé

Provided is a method for producing recycled pellets, capable of using loss films that have been inapplicable so far including a thick loss film, a wide loss film, and a loss film made of a material that has high hardness and therefore is less likely to be bent, and also capable of producing recycled pellets similar to virgin pellets. A method for producing recycled pellets includes the steps of: twisting one or more loss films (R) continuously supplied in one direction while applying a stretch to the loss film; pressurizing a twisted part to pressure-bond contact parts of the loss film (R), thereby forming a twisted string (R); and cutting the twisted string (R) to produce recycled pellets (P). The loss film (R) is preheated at a softening temperature of the loss film (R) prior to twisting the loss film (R) while stretching it.

Abrégé

Provided is a recycled pellets production method, in which loss films that have not been used so far, including a thick loss film, a wide loss film and a loss film made from a material that has high hardness and therefore is less likely to be bent, can be used, and whereby it becomes possible to produce recycled pellets similar to virgin pulp.　A recycled pellets production method is provided, in which: one or more loss films (R) that are supplied continuously in one direction are twisted while stretching the loss films; a pressure is applied to twisted portions in the loss films to compress parts at which the loss films are contacted with each other, thereby forming a twisted string (R); and the twisted string (R) is cut into pieces to produce recycled pellets (P). In the method, before the twisting of the loss films (R) while stretching the loss films (R), the loss films (R) are pre-heated at the softening temperature of the loss films (R).

Abrégé

Provided is a granule trace amount stable supply apparatus that can evenly and stably supply a trace amount of additive agent to a starting material hopper. The present invention relates to a granule trace amount stable supply apparatus 10. A cylindrical body 16 constituting a starting material conveying path has a starting material inlet 16a formed in an upper surface of a rear-end portion and has a starting material outlet 16b formed in a lower surface at a leading end. A conveyance screw 18 is provided rotatably in the interior of the cylindrical body 16. A cover member 20 is provided between the starting material inlet 16a and a base 18a of the conveyance screw 18 located directly below the starting material inlet 16a and covers an upper surface 18b of the base 18a and a rising-side lateral surface 18c of the base 18a while the conveyance screw 18 is rotating.
