| 摘要 |
The invention relates a device for suctioning off waste products of the production machine comprising a suction chamber at which at least a suction element is assembled which extends into a suction space, which is outside the suction chamber in order to convey waste products into the suction chamber, wherein the suction element comprises an inlet area, which is facing the suction space and an outlet area, which ends in the suction chamber.;According to the invention, the suction element comprises a circumferential wall, which is configured with such a curved distribution that during the suctioning a middle negative pressure zone results in the outlet area spaced apart from the wall, which comprises a lower negative pressure than the negative pressure, which results in the outer negative pressure zone between the middle negative pressure zone and the wall wherein the waste products within the suction element flow through mainly in the middle and a contacting of the waste products at the wall can be minimized. |

1. Device (1) for suctioning of waste products (2) of the production machine (3), which are configured as continuous stripes, with
a suction chamber (10) at which at least a suction element (20) is assembled which extends into a suction space (4) which is outside the suction chamber (10) in order to convey waste products (2) into the suction chamber (10), wherein the suction element (20) comprises an inlet area (24), which is facing the suction space (4) and an outlet area (28), which ends in the suction chamber (10) characterized in that the suction element (20) comprises a circumferential wall (30), which is configured with such a curved distribution that during the suctioning a middle negative pressure zone (51) results in the outlet area (28) spaced apart from the wall (30), which comprises a lower negative pressure than the negative pressure, which results in the outer negative pressure zone (52) between the middle negative pressure zone (51) and the wall (30) wherein the waste products (2) within the suction element (20) flow through mainly in the middle and a contacting of the waste products (2) at the wall (30) can be minimized, wherein a means (60, 61, 62, 63, 64) extends into the interior of the suction element (20) in a way that the cross section of the suction element (20) narrowed between the inlet area (24) and the outlet area (28). |
