A method and device for feeding laundry pieces to a laundry treatment installation. Laundry pieces are fed to ironers by infeed machines. In practice, a front transverse periphery of a laundry piece is folded back on itself. In order to prevent this, infeed machines have stretching installations that have belt conveyors that lie on top of one another, one of which is briefly decelerated so as to unravel a front transverse periphery of the laundry piece that is folded back on itself. This deceleration decreases the infeed performance. One belt conveyor of the present stretching installation is at least temporarily driven at a faster speed to unravel a transverse periphery of the laundry piece that has potentially folded back on itself before the laundry piece runs into the ironer, increasing the infeed performance as it is no longer necessary for either of the belt conveyors to be decelerated.
