The present invention relates to a tape guiding device for a coating device according to the preamble of claim 1.

Such a tape guide device is known, for example from the FR-A-2 230 207 patent.

In this patent, a winding machine with a tangential winding head is proposed for covering cables with tape. The placement of the elastic band is achieved by a uniform axial movement of the cable and by a tangential rotation movement of the ribbon around the cable by means of a winding head. By synchronizing the two movements, the tape can be wrapped around the cable without gaps or with a uniform overlap. In order to maintain a uniform tensile tension of the tape in relation to the cross section of the tape from the recovery roller to the cable, a tape guide device with tape deviation fingers has been provided, which leads the tape tangentially to the cable a coat. Through this configuration of a tape guide device, an optimum coating with

represent:

Fig. 1 is a perspective view of the tape guide device on a tangential winding head;

Fig. 2, a side view of the tape guide device; and

Fig. 3, a 90% rotated side view

In fig. 1 is shown a coating device (1) in an example of a tangential winding head (2), with a guide device (3) of the tape. On the tangential winding head (2), a ribbon supply roller (4) is mounted, oriented with its axis of rotation parallel to the longitudinal axis of the object (5) to be coated with the ribbon. The tape guide device (3) is rigidly connected with the tangential winding head (2) and consists of a winding cylinder (6) and an oscillatingly sensed tape deflection cylinder (7). for the coating of the object (5), the tangential winding head (2) rotates in the direction of the arrow (8), while the object (5) receives a progression movement along its longitudinal axis (9), synchronized with rotation By means of the two cylinders (6) and (7), the tape (10) is taken from the supply roller (4) at an angle of inclination tangential to the object (5).

Further details of the tape guide device (3) result from fig. 2, with the oscillation axis (11) of the ribbon deviation cylinder (7) arranged at the side and making a right angle with the longitudinal axis (9) of the object (5) to be coated and making a right angle tangentially in the middle of the cylinder (7). The ribbon deviation cylinder (7) is connected to the oscillating support (13) by means of an angled plate (12). As appropriate, the winding cylinder (6) or / and the ribbon deflection cylinder (7) can be selectively provided with a dead path, not shown, with which the retraction of the ribbon (10) is prevented, in especially when the tape is elastic.

In fig. 3 is a view in the direction of the arrow (A) of the tape guide device (3). Here you can clearly see how the ribbon deflection cylinder (7) with the oscillating support (13) can automatically orient itself, by means of the ribbon pulling force, according to a predetermined propeller angle (X) of the tape (10). The one-sided connection of the ribbon deflection cylinder (7) with the angled folded plate (12) has the advantage of making possible the simple manual placement of the ribbon (10) around the cylinder.
