PROBLEM TO BE SOLVED: To provide a method and device for manufacturing a cut object of an acrylic resin, which maintains productivity, suppresses manufacturing costs, restrains the occurrence of cracks, and prevents deformation.;SOLUTION: The method for manufacturing the cut object 40 of the acrylic resin includes: forming an acrylic resin band body 30 by melting and extruding the acrylic resin; maintaining the acrylic resin band body 30 at the temperature of (Tg-40°C) and higher (Tg represents glass transition temperature of the acrylic resin); and cutting the acrylic resin band body 30 at a temperature between (Tg-40°C) and (Tg-15°C). The manufacturing device 1 for the cut object 40 of the acrylic resin is provided with: a forming means 10 that forms the acrylic resin band body 30 by melting and extruding the acrylic resin; and a cutting means 20 that maintains the acrylic resin band body 30 at the temperature of (Tg-40°C) and higher, and cuts the acrylic resin band body 30 at the temperature between (Tg-40°C) and (Tg-15°C).;COPYRIGHT: (C)2009,JPO&INPIT
