Cable tie device

^ The invention relates to a cable binding device, more precisely a device for wrapping several electrical cables with an adhesive tape. It can also be used to hold multiple rods, tubes, To wrap hoses or other elongated objects with tape, wire, string or other binding material and with it to bundle.

With the increase in the laying of bundled single conductor cables instead of three-wire cables in the 10 kV range, there is a need to run the cables at regular intervals for short-circuit reasons To bundle distances »This is usually glass fiber reinforced Adhesive tapes are used, which are currently applied by fitters (^ by hand. This work is cumbersome, time consuming and expensive.

The invention is therefore based on the object of an assembly tool to create what a shortening and simplification allows the cables to be wrapped with adhesive tape.

According to the invention, this object is achieved in that at a base plate, which is the shape of a one-jaw wrench has, the mouth is narrower than the circular opening behind it, and that a guide ring around this opening is attached with a groove in which a ring also having a mouth is rotatably guided, which is a holder for the Binding material roll.

According to the further invention, the binding ring is driven by means of a toothed ring which is introduced into it by means of an endless one Chain that runs over several guide rollers and that of a crank arranged on the handle part of the base plate moved by hand with a toothed ring or driven by an electric motor (claims 2 and 5).

The binding ring could also be driven by a V-belt and pulley, or by omitting the transmission links directly from an electric motor connected to it. '

When driven by a chain, its guide rollers and the crank drive are preferably arranged in a Y-shape: 3 rollers in the corner points and the crank in the star point (claim 3). This has the advantage that the crank and the binding ring rotate in the same direction have what makes the handling of the assembly tool easier.

The chain guide can also have a triangular shape: 2 rollers in the upper corners and the crank in the lower corner (claim 4) = This results in a slight shortening of the tool Sj but unequal direction of rotation of the crank and the binding ring.

An embodiment of the invention is shown in the drawing and is described in more detail below. Show it

The structure and operation of the binding device can be easily understood from the above. In addition, what is essential to the invention To take a closer look at the jaw part: The jaw opening 2 of the base plate 1, guide ring 4 and binding ring 5 is the same size and the opening angle from the center of the circular opening 3 to the outer corners of the mouth of the binding ring 5 lies between 60

- 'and 90 (claim 6). The mouth opening is preferably between 60 and 100 mm, the diameter of the circular opening 3 between 70 and 130 mm. These values apply to the preferred Embodiment of the binding device for wrapping three-core cables in the 10 kV range. Versions for other purposes can be smaller or larger.

The roll with the binding material is firmly attached to the holder 6, which is firmly attached to the binding ring 5. Sliding on is made easier by the rounded upper edge of the holding cylinder or its slightly conical shape. The fastening is done by a press fit, spring or pin. The way of working () is simplified if one uses rolls with a binding material length that is just sufficient for one wrapping point (claim 7). The fitter takes the binding device with the handle 10 in his hand and grasps the cables to be bundled with the widened mouth 3. Then sr sets the beginning of the adhesive tape on a cable and cranks off the tape, the binding ring 5 with the tape roll on the holder 6 encircles the cable and so wraps it.
