The present invention proposes a method for forming a roll carrying a certain length of closure tape for continuous feed into a diaper manufacturing line, said method comprising the steps of lamination of a continuous substrate with a continuous mechanical fastener strip at a distal portion of said substrate in the cross direction, application of adhesive to a second distal edge portion of said substrate in the cross direction and winding said adhesive applied continuous substrate into a roll. Said method further comprises unwinding a roll of a certain length of closure tape, subjecting said certain length of unwound closure tape to heat by means of heated cylinders after the open time of said pre-coated adhesive is terminated, cutting said certain length of unwound closure tape to specific shapes in the form of closure tapes, attaching said shaped closure tapes to diaper bodies at said adhesive pre-coated regions.
