Description

The innovation concerns a covered with self-adhesive film Tension band for fastening and securing the position of cables and pipes.

On ships, in factory halls and similar production systems, cable and pipe strings are usually made in groups laid in cable ducts, where they can be easily accessed and monitored at any time. To such cable and To fasten pipe strings individually or in groups in a parallel guide to a holding device, one uses usually thin flat steel strips, as they are also used in the packaging industry for packing cardboard boxes and boxes be used.

These tapes are cut from a supply roll in the required length and then after being looped around of the cable and pipe strands to connect the tape ends with a crimp sleeve.

If it is about the fastening of cables or pipes, these tapes must be sheathed, thus the sharp edges of the steel belt, especially in the event of vibrations or shocks, such as on ships or other vehicles, do not cut into the rope and cause damage. This sheathing So far this has usually been done by placing a plastic film strip on the top and bottom of the steel strip glued on, followed by two more adhesive film strips folded over in a U-shape Also cover the edges of the steel strip and the edge parts of the upper and lower foil cover.

Such a covered tape is complex to manufacture and therefore relatively expensive. With axial movements of the To hold strands, the edge coatings can come off.

To eliminate the above disadvantages, it is proposed according to the innovation that a single self-adhesive sheath be used To use plastic film tape, which envelops the steel tape in the manner of a helix so that slightly overlap the longitudinal edges of the film strip.

Further details can be found in the attached Drawing.

In the drawing show in high magnification:

FIG. 1 shows a chemical cross section through previously known encased tensioning straps,

FIG. 2 shows a plan view of a tensioning band according to the pattern

FIG. 3 shows a side view of FIG. 2

The following dimensions are given as an example:

Steel strap width: 10 - 20 mm

Steel strip thickness 0.3 - 1.00 mm
Foil width 30 mm

Foil thickness 0.15 mm
Foil tape overlap 3 mm
Helix angle of inclination approx. 45 °

The tension band according to the pattern not only avoids the disadvantages mentioned above, but also has the advantage that a longer length of tensioning strap can be accommodated on a supply reel with given dimensions. In the case of the previously known tensioning straps, the thickness of a winding layer on the supply reel results from the thickness of the steel strip plus four times the thickness of the foil strip,

whereas with the pattern-based tensioning band, the overlapping points usually do not lie on top of each other come, so that in general the position of a winding thickness is two film thicknesses less.

Claims (4)

Protection claims 1. Tensioning band covered with self-adhesive film for Fastening and securing the position of cable and pipe strings, characterized in that the sheathing is formed by a single self-adhesive plastic film tape, which the steel tape in Kind of a helix encased in such a way that the longitudinal edges of the foil strip slightly overlap. 2. Tensioning strap according to claim 1, characterized in that that the helix angle is about 45 °. 3. Tensioning strap according to claim 1 and 2, characterized in that the width of the foil tape is about twice that corresponds to the steel belt width. 4. Tensioning strap according to claim 1 to 3, characterized in that the overlap width of the helical applied film tape corresponds approximately to the tenth part of the film width.
