Abstract
Method for feeding material into a shaping device in a pneumatic materials conveying system, in which method material, such as waste material is fed into a shaping device, and/or through it, in a feeder channel by the aid of at least partly gravity and at least partly suction and/or a pressure difference, which shaping device is a rotary shaper, with which the material is processed so as to be denser and is conveyed onwards. In the material infeed direction before the rotary shaper is a movable arresting device, which arresting device has a first position, in which it extends into the feeder channel and in which first position the arresting device receives at least some of the force effect produced by the material in the feeder channel and in which the transfer of the material in the feeder channel is limited, if necessary, with the arresting device, and which arresting device has a second position, in which the arresting device does not extend into the feeder channel.
