Abstract: An apparatus for transporting a package doffed by a spinning frame to a winder. Packages are independently transported on a package supply conveyor by means of a peg tray which includes a guide member for securing thereto an end of a yarn extracted from the package. The package carrying tray is delivered to a frictionless inclined pathway and proceeds under its own weight to a winding position adjacent a winding unit.

Abstract: Provided are pre-expanded polypropylene resin particles having a dimensional expansion coefficient of 1.5% or more determined with a thermomechanical analyzer at a constant compressive load of 1 mg during heating from 30° C. to 100° C. at a temperature increase rate of 10° C./min. Using the pre-expanded polypropylene resin particles can yield an in-mold foam molded product of polypropylene resin having few wrinkles and small dimensional shrinkage without pretreatment such as internal pressure application or compression packing during packing the pre-expanded particles in a mold for in-mold foam molding.

Abstract: Polyolefin-based resin pre-expanded particles include a polyolefin-based resin composition including a polyolefin-based resin, a sterically hindered amine ether flame retardant expressed by the general formula (1): R1NHCH2CH2CH2NR2CH2CH2NR3CH2CH2CH2NHR4 (1), and a phosphoric ester. The polyolefin-based resin pre-expanded particles are flame retardant polyolefin-based resin pre-expanded particles that can have good in-mold expansion moldability and exhibit excellent flame resistance compared to the conventional pre-expanded particles even when molded into a sample having a higher density or a larger thickness without using a halogen flame retardant, and that do not generate harmful gas during burning.
