5 Lifting strap or lashing strap with wide sclinnal fabric

7 The invention relates to textile lifting straps or lashing belts.

8 straps, the lifting strap ends are designed as loops. These loops

9 are usually hooked into the hook of a crane or lifting gear,

10 in order to be able to lift the load wrapped in the lifting strap using the crane.

11 Since two lifting straps are often arranged crosswise and all lifting

12 strap loops lead into a crane hook, the loop area must have a

13 have the smallest possible cross-section. Otherwise the crane hook is too small,

14 to accommodate all lifting strap loops. 15

16 According to the state of the art, it is therefore usual for the lifting strap to form

17 Fold the tape material once in the warp direction in the area of the ends to form a Hal-

18 ation of the band cross-section. The band folding is thus permanently

20 are sewn together. After sewing, the actual loop is formed.

21 by folding the strap end in the weft direction and placing the lashing strap end on

22 the remaining tape is sewn with a so-called main seam. 23

24 It is also known for lashing straps to have tapered ends.

25 areas. These end areas, which are tapered in cross-section,

26 to form a loop, which is secured by a loop holder on a

27 metal hooks are pulled. The end area is again covered with the remaining tape

28 sewn with a main seam for permanent adaptation of the hook on the

29 Lashing strap. To taper in the end area, the strap material is also

30 warp direction from one side or even from both sides and

31 sewn.
32

33 The disadvantage of this loop production according to the state of the art is the

34 Necessity of folding the belt material once in the warp direction, which

35 can currently only be carried out manually. Another disadvantage is the uneven transfer

36 passage from the middle area to the tapered loop area and the

37 inevitably forming abutting edge. In the area of the abutting edge, the

1 Tape material is particularly susceptible to damage. Object of the invention

2 is therefore to provide a loop area on lifting straps or lashing belts.

3 without having to fold and sew the tape material. 4

5 The solution to the problem consists in the combination of features of claim 1.

6 According to the invention, the distance between the fabric warp threads during the

7 Weaving process at or at the ends of the tape, i.e. in the later loop areas

8 chen continuously reduced. By reducing the warp thread spacing,

9 the width of the band is also reduced at the same time. This reduction in the band width 10 also causes the loop cross-section to taper.

12 The advantage of the invention is that the loop areas can be made as narrow as desired.

13 can be designed. The lifting straps have a larger diameter in the loop areas,

14 re belt height. In the area of the crane hook, however, the belt width and

15 the band height is not the bottleneck factor. With the help of the invention it is therefore possible

16 borrowed, either a larger number of lifting strap loops on existing

17 crane hooks or to lock the same number of lifting straps

18 loops to enable smaller and therefore lighter crane hooks to be used in the future.

19 Another significant advantage, both in terms of functionality and safety,

20 The advantage is the uniform flow of force over the force-carrying warp threads

21 in the transition area from the remaining band area to the loop area. The

22 The load-bearing capacity of the belt material used is therefore better utilized than

23 according to the state of the art, which significantly increases the safety of use. The

24 The soft, fluid band path created by the invention thus causes a

25 better utilization of the substance of the woven band material. Finally

26, the fixing seam for the band fold in the loop area is omitted, so that the

27 Loop area can no longer be destroyed even by wear of the fixing seam.

28 From a manufacturing point of view, the possibility of using numerically

29 controlled weaving machines, which only use the

30 warp thread spacing must be reduced.
31

32 Particularly advantageous in terms of force distribution is a continuously moving

33 reducing warp thread spacing according to claim 2. It is also advantageous here,

34 that the loop area in its actual contact zone with the crane hook

35 is particularly narrow and therefore space-efficient. 36

10 Fig. 3 a lashing strap end with permanently attached hook,

11 Fig. 4 shows a variant of the lashing strap end modified compared to Fig. 3 with per-

12 manently reduced lashing strap end width in the area of the folded back

13th volume end and

18 The band 1 has the band areas 2 and the loop area 3. in

19 Loop area 3 is the distance between the loops running in warp direction 4 and

20 drawings in detail not shown warp threads measured in weft direction

21 5 is less than in the belt areas 2 . This reduction in the warp thread

22 distance measured in the direction of fire 5 causes a tapering cross-

23 section of the band 1 in the loop area 3. In Fig. 1 below the

24 of the band 1 shown, three different band heights 6 are indicated graphically.

25 It can be seen that the band height 6 in the loop area 3 is much higher

26 than in band area 2. In addition, it is indicated that the band height 6 in the over-

27 transition area 7 between the band area 2 and the area of the loop

28 Reichs 3 with the smallest width measured in the direction of fire 5 is already higher

29 than in band area 2.
30

31 To form the loop 8, the band end 9 is pulled in warp direction 4 onto the remaining

32 before band 1 is folded back so that band 1 in the weft direction

1 5 is folded. The folded back end of the tape is then fastened using the main seam 10

2 is sewn with the remaining band 1 to form the loop 8.

4 In the lashing strap 11, the strap material in the loop area 3 is also

5 the band area 2 in its own width running in the weft direction 5 reduced

6 . The reduction of the width in the area of the loop 8 is again

7 by reducing the warp thread spacing measured in the weft direction 5.

8 Before sewing the loop 8 using the main seam 10, the lashing strap 11

9, the hook 12 is additionally attached in such a way that the lashing strap end is

10 a fixing slot 13 is pulled on the hook 12, is folded in the direction of the cord 4 and

11 is sewn to the remaining band 1 by means of the main seam 10.
12

13 In the embodiment shown in Fig. 4, not only the actual

14 loop 8 is tapered, but the entire area of the band end 9, which is on

15 the remaining band 1 is folded back and fixed by means of the main seam 10 on the

16 remaining band 1 is sewn. The area of the band that is not folded back

17 of the 10 has a width corresponding to the lashing strap width 14, while the

18 lashing strap end width 15 is significantly smaller than the lashing strap width 14. In contrast,

19 is in the embodiment shown in Fig. 5, alternative to the embodiment in Fig. 4

20 embodiment, the entire band end 9 is tapered. Both the

21 folded back area of the band end 9 as well as the area connected to the rest

22 Band 1 directly adjacent, non-folded back area of the band end 9

23 have significantly smaller lashing strap widths than lashing strap width 14.

24 denbreite 15. In both embodiments, the

25 lashing strap width 14 reduced lashing strap end width 15 also the length of the main

26 seam 10 is reduced, which reduces the amount of time required to make the main seam 10.

27 Sewing effort is significantly reduced.
