Abstract

Claims (45)

1 . A collecting bag for receiving material to be collected, the collecting bag comprising:

a woven-fabric cloth delimiting a receiving space, wherein the receiving space is delimited by outer edges of the collecting bag;

said woven-fabric cloth being at least partially air-permeable;

said receiving space having an inlet opening for a conveying airflow which supplies the material to be collected and an outlet opening for at least partially discharging the conveying airflow into the environment;

said receiving space having a closable emptying opening for retrieving the material to be collected;

said inlet opening being provided on a first edge of the outer edges of the collecting bag;

said emptying opening being provided on a second edge of the outer edges of the collecting bag, wherein said second edge of the outer edges is opposite to said first edge of the outer edges;

said first edge of the outer edges and said second edge of the outer edges being opposite one another at a spacing and connected to one another by way of a first longitudinal edge of the outer edges of the collecting bag and a second longitudinal edge of the outer edges of the collecting bag;

said outlet opening for at least partially discharging the conveying airflow being disposed in a side wall of the collecting bag, between said emptying opening and said inlet opening;

said outlet opening being assigned a closure element which in a closure position completely closes the outlet opening;

said outlet opening being formed by a fabric net which is held in said side wall; said closure element is a closure cloth which covers said fabric net in a planar manner;

said closure cloth being attached to said side wall except at an outflow opening; and,

said outflow opening being configured to be closed by a closing flap fixed to said side wall of the collecting bag.

2 . The collecting bag of claim 1 , wherein said side wall defines a side wall area; and, said outlet opening defines an outlet opening area which corresponds to 10% to 20% of said side wall area.

3 . The collecting bag of claim 1 , wherein the collecting bag between said first edge and said second edge is divided into a first half and a second half by an imaginary central plane; said outlet opening lies in said first half; and, said inlet opening lies in said second half.

4 . The collecting bag according of claim 1 , wherein said outlet opening lies closer to said emptying opening than to said inlet opening.

5 . The collecting bag of claim 1 , wherein said outlet opening is formed by a fabric net which is held in said side wall.

6 . The collecting bag of claim 1 , wherein said outflow opening is co-aligned with said second longitudinal edge of said collecting bag.

7 . The collecting bag of claim 1 , wherein said emptying opening has at least one opening edge which is reinforced with a flat bar; said flat bar in a longitudinal direction thereof is divided into at least two mutually separate segments; and, said emptying opening is configured to be closed by folding back said at least one opening edge which is reinforced with said flat bar.

8 . The collecting bag of claim 1 , wherein the collecting bag in a lateral view has a rectangular basic shape with narrow sides and longitudinal sides; said first edge and said second edge are on said narrow sides; and, said first longitudinal edge and said second longitudinal edge are configured on said longitudinal sides.

9 . The collecting bag of claim 1 , the collecting bag, proceeding from said first edge with said inlet opening is configured so as to widen in a direction towards said second edge with said emptying opening.

10 . The collecting bag of claim 1 , wherein said inlet opening is configured having an inner channel section of a defined length that opens into said receiving space.

11 . The collecting bag of claim 10 , wherein said inner channel section widens from said inlet opening towards said receiving space.

12 . The collecting bag of claim 10 , wherein said inner channel section, which adjoins said inlet opening, opens into said receiving space as a diffusor.

13 . A collecting bag for receiving material to be collected, the collecting bag comprising:

a woven-fabric cloth delimiting a receiving space, wherein the receiving space is delimited by outer edges of the collecting bag;

said woven-fabric cloth being at least partially air-permeable;

said receiving space having an inlet opening for a conveying airflow which supplies the material to be collected and an outlet opening for at least partially discharging the conveying airflow into the environment;

said receiving space having a closable emptying opening for retrieving the material to be collected;

said inlet opening being provided on a first edge of the outer edges of the collecting bag;

said emptying opening being provided on a second edge of the outer edges of the collecting bag, wherein said second edge of the outer edges is opposite to said first edge of the outer edges;

said first edge of the outer edges and said second edge of the outer edges being opposite one another at a spacing and connected to one another by way of a first longitudinal edge of the outer edges of the collecting bag and a second longitudinal edge of the outer edges of the collecting bag;

said outlet opening for at least partially discharging the conveying airflow being disposed in a side wall of the collecting bag, between said emptying opening and said inlet opening;

said outlet opening being assigned a closure element which in a closure position completely closes the outlet opening;

said outlet opening being formed by a fabric net which is held in said side wall; said closure element is a closure cloth which covers said fabric net in a planar manner;

said closure cloth being attached to said side wall except at an outflow opening;

an opening edge of said closure element that delimits said outflow opening being reinforced with a flat bar; and,

said flat bar in a longitudinal direction thereof being divided into at least two mutually separate segments.

14 . The collecting bag of claim 13 , wherein said side wall defines a side wall area; and, said outlet opening defines an outlet opening area which corresponds to 10% to 20% of said side wall area.

15 . The collecting bag of claim 13 , wherein the collecting bag between said first edge and said second edge is divided into a first half and a second half by an imaginary central plane; said outlet opening lies in said first half; and, said inlet opening lies in said second half.

16 . The collecting bag according of claim 13 , wherein said outlet opening lies closer to said emptying opening than to said inlet opening.

17 . The collecting bag of claim 13 , wherein said outflow opening is co-aligned with said second longitudinal edge of said collecting bag.

18 . The collecting bag of claim 13 , wherein said emptying opening has at least one opening edge which is reinforced with a flat bar; said flat bar in a longitudinal direction thereof is divided into at least two mutually separate segments; and, said emptying opening is configured to be closed by folding back said at least one opening edge which is reinforced with said flat bar.

19 . The collecting bag of claim 13 , wherein the collecting bag in a lateral view has a rectangular basic shape with narrow sides and longitudinal sides; said first edge and said second edge are on said narrow sides; and, said first longitudinal edge and said second longitudinal edge are configured on said longitudinal sides.

20 . The collecting bag of claim 13 , the collecting bag, proceeding from said first edge with said inlet opening is configured so as to widen in a direction towards said second edge with said emptying opening.
