Claim Text:
1. A method for feeding material into a shaping device in a pneumatic materials conveying system, comprising: feeding material into a feeder channel by the aid of at least partly gravity and at least partly suction and/or a pressure difference, feeding material from the feeder channel into and through a rotary shaping device to make the material denser after being compacted in the shaping device as compared to prior to entering the shaping device, feeding material from the shaping device into a conveying pipe, providing a movable arresting means for selectively engaging the material in the feeder channel, the movable arresting means being arranged in a material infeed direction before the rotary shaper, moving the movable arresting means between a first position wherein the movable arresting means extends into the feeder channel and in which first position the arresting means receives at least some of the force effect produced by the material in the feeder channel, and moving the movable arresting means to a second position wherein the arresting means does not extend into the feeder channel.
