The present invention provides an apparatus with increased flexibility associated with various types and characteristics of filters, so that these sheets can be manufactured using the laid sheet material supplied by the apparatus. An apparatus for feeding a continuous web of curled sheet material (2) to a rod forming apparatus comprises a winding unit (3) for unwinding the sheet material from a bobbin (21) provided with the sheet material. A sheet-feeding unit (7) for bringing the sheet material together, and a continuous web of sheet material (2) disposed upstream of the sheet-feeding unit (7) when viewed in the conveying direction of the sheet material (2) And a control unit (9) for controlling the various units of the apparatus in response to sensor signals received from the respective units.
