The invention relates to a method for granulating plastics. According to said method, melt that is discharged from a melt generator is delivered to several pelletizing heads via a starting valve (1) that features several operating positions, the melt being granulated by means of the pelletizing heads. The invention further relates to a device for granulating plastics, comprising a starting valve (1) that is provided with at least one melt generator connection (3, 4), at least two granulator connections (5, 6), and a switching gate (14) for selectively connecting the melt generator connection to at least one of the granulator connections. One respective pelletizing head is connected to the at least two granulator connections while a melt generator having a variable melt volume flow rate isconnected to the melt generator connection. The invention is characterized in that several pelletizing heads having different passage capacities are used, whereby the throughput window is increased overall in order to be able to operate in a largely continuous manner without interruptions while inevitable starting processes are shortened or are minimized regarding the produced start-up material by connecting pelletizing heads having low throughput capacities.
