Abstract
In order to open the start of a wadding from a wadding lap, a current of air is produced by a nozzle in the unrolling direction of the wadding lap substantially tangential of the wadding lap and with a spacing to the periphery of the wadding lap. The current of air is generated across the width of the wadding lap. In addition, a guide plate extends from the nozzle to guide the start of the wadding to a joining apparatus. The nozzle and guide plate are pivotally mounted about an axis of a lap roller to facilitate guidance of the opened start of wadding to the joining apparatus.
