Abstract: In band ironers, laundry items are moved along a pressing surface of a stationary ironer roller by an ironer band that entrains the laundry items, wherein the laundry items slide with slip along a lateral surface of the ironer roller. As the speed of the ironer increases, slip between the laundry items and the lateral surface of the ironer roller increases. When the desired ironing quality makes less slip necessary, the circumferential speed of the ironer band has to be reduced, and the throughput of the band ironer suffers. The invention is to drive the ironer roller in a circumferential manner wherein the slip between the ironer roller and the laundry items is adjusted in an arbitrary manner as a result of adjusting the rotational speed of the drive of the ironer roller and/or the circumferential speed of the ironer band without reducing the throughput of the band ironer.
