  • Patent number: 11161960
    Abstract: A method for rotary die cutting. The method may include providing, to an accumulator, an input comprising a melt. The method may include processing, by the accumulator utilizing a set of rolls, the melt to form a sheet of material. The method may include providing, from the accumulator, the sheet of material to a dandy roll. The method may include providing, from the dandy roll, the sheet of material to a rotary die. The method may include cutting, by the rotary die, a product from the sheet of material. The method may include providing, from the rotary die, the product to a stacker.
