Abstract

Belt mangles, in which a revolvingly driven mangle belt runs along on the outside of the mangle body which is curved in a trough-like manner, convey in an entrained manner laundry items to be mangled along a smooth flattening face of the mangle body. Slippage between the mangle belt and the laundry items, which causes the quality of mangling to suffer, can occur. A mangle belt is provided with a structured outer face to bear on the laundry items to be entrained. The outer face is formed from a needled felt from highly temperature-resistant man-made fibers. On account of the structuring of the outer face of the mangle belt, a rough entrainment face or adhesion face, respectively, for the laundry items, that ensures slippage-free entrainment of the laundry items by the mangle belt while conveying the laundry items along the flattening face of the mangle body, is created.

First claim

The invention claimed is:

1. A mangle for mangling laundry items, having at least one stationary mangle body ( 11 ; 31 ; 32 ; 44 ; 74 ) and at least one revolvingly drivable mangle belt ( 18 ; 38 ; 51 ; 77 ) which is assigned to the at least one mangle body ( 11 ; 31 ; 32 ; 44 ; 74 ), wherein the laundry items are conveyable by the mangle belt ( 18 ; 38 ; 51 ; 77 ) through a mangling gap ( 19 ) between the mangle body ( 11 ; 31 ; 32 ; 44 ; 74 ) and the mangle belt ( 18 ; 38 ; 51 ; 77 ), wherein the at least one mangle belt ( 18 ; 38 ; 51 ; 77 ) comprises an outer face ( 20 ; 39 ; 53 ; 95 ) which is structured so as to entrain the laundry items, wherein the at least one mangle belt ( 18 ; 38 ; 51 ; 77 ) comprises longitudinal bracings ( 64 ; 69 ) and/or transverse bracings ( 65 ; 70 ).

2. The mangle according to claim 1 , wherein the outer face ( 20 ; 39 ; 53 ; 95 ) of the mangle belt ( 18 ; 38 ; 51 ; 77 , which entrains the laundry items, is configured so as to be rough or roughened, respectively.

3. The mangle according to claim 1 , wherein the outer face ( 20 ; 39 ; 53 ; 95 ) of the mangle belt ( 18 ; 38 ; 51 ; 77 ) is configured so as to be rough and roughened in such a manner that the outer face ( 20 ; 39 ; 53 ; 95 ) disposes of a coefficient of friction which is greater than a coefficient of friction of the laundry items.

4. The mangle according to claim 1 , wherein the outer face ( 20 ; 39 ; 53 ; 95 ) of the mangle belt ( 18 ; 38 ; 51 ; 77 ) which comes into contact with the laundry items is configured so as to be an entrainment face, adhesion face and/or friction face.

5. The mangle according to claim 4 , wherein the mangle body ( 44 ) is configured so as to be planar, and the outer face ( 53 ) or entrainment face, adhesion face and/or friction face, respectively, of the mangle belt ( 51 ) cooperates with the flattening face ( 45 ) of the planar mangle body ( 44 ).

6. The mangle according to claim 1 , wherein the mangle belt ( 18 ; 38 ; 51 ; 77 ) comprises at least one entrainment layer ( 63 ; 67 ), wherein a side of the entrainment layer ( 63 ; 67 ) which points toward the laundry items or the mangle body ( 11 ; 31 ; 32 ; 44 ; 74 ), respectively, forms the outer face ( 20 ; 39 ; 53 ; 95 ).

7. The mangle according to claim 6 , wherein the longitudinal bracings ( 64 ; 69 ) and/or transverse bracings ( 65 ; 70 ) are disposed in the entrainment layer ( 63 ; 67 ) or cooperate with a traction support ( 68 ) of the mangle belt ( 18 ; 38 ; 51 ; 77 ), wherein a reverse side of the entrainment layer ( 63 ; 67 ), which lies opposite the entrainment layer ( 63 ; 67 ), is fixedly connected to the traction support ( 68 ).

8. The mangle according to claim 6 , wherein the at least one entrainment layer ( 63 ; 67 ) is at least in part formed from a coarsely structured felt-type material having a structured surface for forming the outer face ( 20 ; 39 ; 53 ; 95 ).

9. The mangle according to claim 8 , wherein the felt-type material of at least the entrainment layer ( 63 ; 67 ) is at least for the most part formed from heat resistant plastic material.

10. The mangle according to claim 6 , wherein the at least one entrainment layer ( 63 ; 67 ) is at least in part formed from a felt-type material having a structured surface for forming the outer face ( 20 ; 39 ; 53 ; 95 ).

11. The mangle according to claim 10 , wherein the felt-type material of at least the entrainment layer ( 63 ; 67 ) is at least for the most part formed from plastic material wherein the plastic material is heat resistant.

12. The mangle according to claim 11 , wherein the felt-type material is a needled felt.

13. The mangle according to claim 10 , wherein the felt-type material of at least the entrainment layer ( 63 ; 67 ) is at least for the most part formed from man-made fibers.

14. The mangle according to claim 13 , wherein the felt-type material of at least the entrainment layer ( 63 ; 67 ) is a needled felt.

15. The mangle according to claim 14 , wherein the felt-type material of at least the entrainment layer ( 63 ; 67 ) is at least for the most part formed from heat resistant plastic fibers.

16. The mangle according to claim 1 , wherein the mangle body ( 11 ; 31 ; 32 ) is curved in a trough-like manner, so as to form an outer face or lower-side flattening face ( 12 ), respectively, which is outwardly curved in a convex manner, and the outer face ( 20 ; 39 ) of the mangle belt ( 18 ; 38 ) which bears on the laundry items cooperates with the flattening face ( 12 ) of the mangle body ( 11 ; 31 ; 32 ), which is outwardly curved in a convex manner.

17. The mangle according to claim 1 , wherein the respective mangle belt ( 18 ; 38 ; 51 ; 77 ) is configured for pressing the laundry items against the mangle body ( 11 ; 31 ; 32 ; 44 ; 74 ).

18. The mangle according to claim 1 , wherein the mangle body ( 44 ) is configured for pressing the laundry items against the mangle belt ( 51 ), and/or means by way of which the laundry items are pressable by the mangle body ( 44 ) against the mangle belt ( 53 ) are provided.

19. The mangle according to claim 1 , wherein the mangle body ( 74 ) is configured as a stationary drum, wherein the mangle body ( 74 ) for the most part is surrounded by the revolvingly driven mangle belt ( 77 ).

20. The mangle according to claim 1 , wherein the at least one mangle body ( 11 ; 31 ; 32 ; 44 ; 74 ) is at least in part configured so as to be double-walled and comprises at least one cavity ( 13 ; 46 ) for a heat-carrier medium in the double-walled region.

21. The mangle according to claim 1 , wherein the mangle body ( 74 ) is configured as a stationary cylindrical drum, wherein the mangle body ( 74 ) for the most part is surrounded by the revolvingly driven mangle belt ( 77 ).
